Abstract

The lamp has LEDs (13e1, 13e2, 13e3) controllable and activatable by a signal line, and an electrically erasable programmable read only memory (EEPROM) (22e). The EEPROM registers a data set describing characteristics of the LEDs, where the data set contains an information about a maximum, measured luminous flux, measured light color, light wavelength, exactly measured spectrum of light and temperature-dependent behavior of the LEDs. An independent claim is also included for a device for controlling a lamp with two different colored LEDs.

Description

The invention initially relates to a luminaire according to the preamble of claim 1.

Such lights are known and widely used. They have been manufactured by the Applicant for decades.

In particular, the invention relates to an interior or exterior light that can illuminate or illuminate a building part surface, a building surface or an object or can backlight a surface in the manner of an orientation light or decorative light. Furthermore, in particular, the invention relates to such lights, which are in the manufacture, ie factory, equipped with at least one light source.

From the German patent application DE 198 17 073 A1 of the Applicant, it is already known to combine several lights to a network of lights, this, a variety of individually controllable lights having system includes a control unit that can address the individual lights and this control commands or control information sends via a separate signal transmission line. In particular, it is provided in the lights of the prior art that each lamp has a single light source, that is, a single lamp that can be addressed by the transmitted via the signal lines control information, for example, to turn on or off to be dimmed to to blink. The like. In the event that the lamp has a plurality of bulbs of different colors, the control information can also cause a color change or control the light to achieve a color mixed overall light distribution.

The invention relates in particular to a luminaire which can be incorporated into a system or network of individually controllable luminaires and which can be connected to other luminaires and to one or more controllers or control units via a signal line.

In particular, but not exclusively, the luminaire according to the invention can be incorporated into a network of luminaires which operates according to the DALI protocol. DALI (digital addressable lighting interface) is a signal transmission protocol established by the DALI working group at the Zentralverband der Elektrotechnik- und Elektronikindustrie.

From the pre-published manual DALI "AG DALI an activity of the operating committee in the ZVEI", Richard-Pflaum-Verlag Munich, a system for controlling a plurality of lights out, in which each lamp is assigned its own DALI ballast, which has a memory , in which address data and light scene information can be written. The combined into a DALI network Luminaires are connected to the common control via the signal transmission line.

Another generic lamp is described in the post-published German patent application DE 10 2005 009 228 of the applicant.

In the event that several lights in the immediate vicinity, for example next to each other, are arranged and, for. Together, illuminating a surface or illuminating surfaces in the immediate vicinity, the observer almost inevitably feels compelled to compare the colors and brightness emitted by the individual luminaires, that is, luminous fluxes. If, for example, a wall several meters long is flooded by a plurality of luminaires designed as wallwashers, color differences of the individual luminaires, as well as differences in brightness, are obvious.

Depending on which illuminant or which illuminant the luminaire has, variations in the maximum possible luminous flux of the luminous means, with regard to the light color generated by the luminous means, but also aging or temperature-related differences in color or brightness of the illuminant, can already occur due to the production. These are especially useful if several light sources of different colors are arranged in one luminaire and a color mixture is to take place.

The invention is therefore the object of developing a lamp according to the preamble of claim 1 such that it offers the opportunity to prevent the disadvantages described above.

The invention solves this problem with the features of claim 1, in particular with those of the characterizing part, and is accordingly characterized in that the lamp has a memory in the one Record is written that describes at least one property of this bulb.

The principle of the invention thus consists essentially in allocating a memory to the luminaire into which a data record is written. The data record describes at least one property of this luminous means. The property to be described may be, for example, the maximum luminous flux of this luminous means. In particular, in the case of designed as a LED bulb is to be noted in this context that the LED manufacturers offer lot sizes of LEDs that vary even with the best quality and presorting between 70% and 100% in their maximum possible luminous flux. The maximum possible luminous flux is e.g. in particular determined by the wafer quality. This means that a first LED of this lot size can generate a 100% luminous flux and another, second LED of this lot size only a 70% luminous flux. If these two LEDs of the same color installed in two different lights and would not take into account the different levels of maximum luminous flux, so would a lamp with the first LED with maximum control in a traceable manner generate a higher brightness than the other LED.

In the manner according to the invention, the property of the luminous means, that is to say for example the maximum luminous flux, in particular the measured, maximum possible luminous flux of this luminous means, has been inscribed directly or as related information in a memory of the luminaire as a data record. This data set can be taken into account in the later activation of the luminous means, so that when the two luminaires with the two LEDs receive a drive signal to emit maximum brightness, that LED which can generate a higher maximum luminous flux is dimmed by a factor of 70% while the second LED, which can only produce 70% luminous flux, will not be dimmed and will produce its maximum luminous flux. In this way, both lights can produce an equal brightness, so that overall a more uniform impression can be produced. The data set therefore offers the possibility of making a correction taking into account the property, in particular the measured property of the individual luminous means.

The data set is preferably written into the memory at the factory. This can be done, e.g. immediately after the maximum luminous flux has been measured or e.g. when the bulb is mounted in the luminaire. The memory may e.g. be provided by a separate electronic component, which is connected upstream, for example, an existing in the lamp control gear and which retransmits the signals received from a controller via the signal line in the manner of a repeater to the operating device and thus to the light source, automatically correcting taking into account Property of the bulb is made.

Alternatively, the memory can also be read out by a controller connected to the signal line, wherein the controller subsequently takes into account the property of the respective luminous means in the activation of the respective luminaire. In this case, for example, the memory may also be provided by an operating device present in the luminaire, e.g. from a light scene memory of a DALI operating device.

Similarly, as LED's may have different maximum luminous fluxes, LEDs may also vary in color and, for example, have wavelength differences of +/- 5 nm. This parameter can also be determined as a measured value and written into the memory as a property of the luminous means in the form of a data record. In particular, if a plurality of light sources of different colors are provided, an optimized color mixing can take place with knowledge of the exact color of light that the light source generates, so that a plurality of lamps can produce an identical color impression by means of a correspondingly intelligent control.

The record to be written into the memory may contain information about the exact light color of this light source. Instead of an indication that the LED emits, for example, red color, now the exact wavelength of the red region, in particular the maximum of the emission spectrum of this LED can be entered into the memory in the case of a designed as an LED light source. In particular, the measured light color of the light source is recorded as a data record. In addition to the exact light color, a spectrum, ie a spectral light distribution of the light source, can also be written into the memory as a data record. The exact spectrum of the light source can be measured equally at the factory, the spectra of the individual bulbs, in particular with LEDs, can vary.

As a property of the luminous means, in addition to information about the maximum luminous flux and / or information about the exact light color, for example, a temperature-dependent behavior of the luminous means and / or an aging-dependent behavior of the luminous means is considered. Both behaviors can refer both to the maximum permissible luminous flux and to a spectral change. The properties of light bulbs not only play a role in LEDs but also in other light sources, for example in OLEDs or optionally in fluorescent lamps. The invention thus relates to lights, regardless of which type is the existing light in the lamp.

The temperature dependency of the luminous means can play a role, for example, at different ambient temperatures or different chip temperatures, in particular when using LEDs as light sources, the chip temperature also being dependent on the switched-on duration of this LED up to this point in time. In the event that the lamp is associated with a sensor which can detect a temperature, for example an ambient temperature or a chip temperature, in any case a temperature influencing the operation of the luminous means, as a result of the storage of the information on a temperature-dependent behavior of the luminous means, a corresponding correction or adaptation of the control information obtained via the signal line, in particular in the manner described above, for adapting a luminous flux to be emitted or for adapting a color mixing.

If the data record contains information about a light-dependent behavior of the light source, it is advisable to assign a device to the memory which records the operating time of the light source. This can be done for example in the manner of an operating hours counter, for example, in the case of LEDs as a light source not only the turn-on but also the inrush currents or, more precisely, the work done by LEDs plays a role, but are easily detected with a corresponding electronics can. If one knows the total operating time of the luminous means and the aging-dependent behavior of the luminous means, which can show an influence on a spectrum shift and / or on a maximum luminous flux, a corresponding correction or adaptation can take place.

If the luminaire contains information about an aging-dependent behavior of the luminous means, it can furthermore be advantageously provided to control the luminous means in consideration of maximum permissible operating temperatures or, e.g. in the case of LEDs, taking into account maximum allowable operating currents. Without this, e.g. A control unit must automatically limit the maximum permissible operating temperatures or the maximum permissible operating current, thus increasing the service life of the lamps.

Preferably, the lamp is connectable via the signal line with a controller. It can be one or more controllers.

Further preferably, the controller communicates with the lamp via control signals according to the DALI protocol. This allows recourse to a widely used standard.

The luminaire can have a memory which contains a data record or a memory in which a plurality of data records are written or a plurality of memories in which a plurality of data records are arranged.

The memory (s) may include one or more data sets describing one or more characteristics of one or more bulbs.

Preferably, the lamp has a controllable by the controller operating device, in particular a DALI operating device, on. This allows the recourse to known components.

According to a first embodiment of the invention, the memory is arranged in the operating device, i. provided by the operating device. In this case, for example, the memory may be formed by a light scene memory, which is already located in a DALI operating device, so that an existing memory can be used. According to the invention, this memory is described in the factory with the data record or with the data sets which describe the property or the properties of the luminous means or of the luminous means.

The data record located in the memory of the operating device can be transmitted by the controller via the signal line in an advantageous embodiment of the invention when the memory is read. Even if the memory is not arranged in an operating device but in a separate electronic component, it can be provided that the memory can be read out by the controller and the data record can be transmitted to the controller via the signal line. The data record can be recognized and processed by the controller. The controller can then, upon receipt of the data set, send control signals to the luminaire which the Take into account the property of the bulb. This means that the controller transmits control information to the luminaire, in particular to an operating device contained in the luminaire, which are corrected or adapted on the basis of the now communicated properties of the luminous means.

For example, if the controller has received the information that a first lamp of a first lamp can emit a maximum possible 100% luminous flux of a specific light color and another lamp of another lamp of the same light color can emit only a 70% maximum possible luminous flux, and it is desired that both If luminaires are to generate uniform light with the maximum possible brightness, then the controller can send a signal to the first luminaire, according to which the higher-power luminous means existing there should only generate a 70% luminous flux and the weaker luminous means contained in the second luminaire is maximally activated, so that in consequence both luminaires with the two lamps each generate the same luminous flux. Thus, for example, the desired uniform illuminance can be achieved.

According to an advantageous embodiment of the invention, the controller uses the data set for a correction of the control signals to be sent. This means that the properties of the lighting means can be taken into account by the controller before the transmission of the control signals and, in particular in the event that at least two lighting means are connected to the controller, an adaptive correction based on the notified property is made.

The data record can also be stored, for example, in another memory, which is assigned to the controller, for example. It is then no longer absolutely necessary to leave the data record in the memory in the luminaire, so that this memory can be overwritten.

In particular, a reading of the memory and a transmission of the data set to the controller in the context of an initialization of a lighting network done, the controller in a detection process in which the lights are provided, for example, with individual addresses and information about the type of light sources are obtained , also the records that relate to the property of the bulbs to be transmitted.

According to an alternative second embodiment of the invention, the memory is part of a separate electronic component which is connected to the operating device of the signal line. Such a separate electronic component can be connected upstream of an operating device and thus be arranged between the operating device and the controller. It can correct or adjust the control signals received from the controller, which are intended for the operating device, taking into account the data set and send the adjusted control signals to the operating device. In this way, the controller does not notice at all that a component is present which carries out a correction of the transmitted control signals.

It also results in the possibility that the device is connected to several operating devices and receives control signals from the controller, which are intended only for a control gear. When carrying out a corresponding correction, and assuming a corresponding connection wiring, the component can also correct the received control signals to different operating devices or send them in an adapted manner. For this purpose, the component preferably has one or more memories in which different data sets of different lighting means are inscribed. The different light sources are assigned to the different operating devices.

The component can therefore also, for example, the control signals intended only for one operating device, which it receives from the controller, taking into account the different data sets differently correct and adjust differently, and send the differently adapted control signals to the plurality of operating devices. In this way, the device can manage multiple lights in the manner of a sub-system within a network of lights, eg within a DALI network.

According to a further advantageous embodiment of the invention, the lamp has at least two lamps of different colors, which are individually addressed by a controller to achieve a color mixed total light distribution. Further preferably, each illuminant is assigned a data record which describes the property of the associated luminous means.

This embodiment of the invention enables a color-miscible luminaire which contains, for example, a red, a green and a blue luminous means or, alternatively, additionally contains a cyan and an amber-colored luminous means or, alternatively, also contains altogether only two illuminants of different white color, for mixing different shades of white. In the simplest case of a luminaire containing a red, a green and a blue LED, the three LEDs can be measured in the manner described above in the manufacture of the luminaire, with their maximum possible luminous fluxes and their exact, precise light colors in the form of the in the memory or recorded in the memories contained record.

In the case of a lamp comprising a red, a green and a blue LED, there is typically a so-called RGB ballast, ie an operating device which controls all three LEDs together. This operating device can now be preceded by a component which contains a memory in which the data sets which describe the properties of the different three light sources are stored.

If the component receives a control signal from the controller, after which the lamp should generate a certain color, eg a yellow one Color mixing, the device can make a corresponding adjustment in knowledge of the properties of the bulbs and colors or mix colors less strong, so that in total exactly the desired color is achieved.

The invention further relates to a luminaire according to the preamble of claim 32.

Such a lamp is known and has been manufactured by the applicant for some time.

As described above, there is the fundamental problem, at least in the case of some light sources, that they differ with respect to their exact color values and their maximum luminous fluxes. Although a red LED basically produces red light. However, the exact light color can vary by a few nanometers, which is usually production-related and practically unavoidable. Even with other colored bulbs, e.g. blue LEDs, green LEDs or other types of light sources, such as OLEDs (organic LEDs) and other illuminants can detect such deviations of the exact color values and also the maximum lumen output, i. of the maximum luminous flux, occur

While the deviations of the exact color values of the individual illuminants are relatively unproblematic when it comes to a monochromatic luminaire, there is the problem with luminaires that mix color-mixed light, ie light colors, that the desired color is often not exactly met. In particular, if several lights are directly spatially associated with each other and to generate an identical light color, color variations of the mixed colors may arise.

The invention is therefore the object of developing a lamp according to the preamble of claim 32 such that a higher color fastness, ie a higher color rendering quality can be achieved.

The invention solves this problem with the features of claim 32 and is accordingly characterized in that the luminaire has a memory into which a data record containing information about the exact color values of the individual luminous means and / or containing information about the maximum luminous fluxes of the individual luminous means is written is, wherein a correction device is provided which corrects the control signals, taking into account the exact color values and / or the maximum luminous flux and performs a control of the individual lighting means with corrected control signals.

The exact color values and / or the maximum luminous flux can be written into the memory at the factory or directly in the form of a data record containing this information. The writing process may be preceded by a measuring operation which measures the exact color value at the factory, for example the exact wavelength emitted by the individual LED and / or the maximum luminous flux.

A correction device can carry out an adaptation and correction of the control signals with knowledge of the data set, so that the control of the individual light sources is carried out in a corrected manner. This allows exact mixing colors, i. color-mixed light distributions are generated, which correspond exactly to the color mixing value that is desired.

For the purposes of the invention, a measured color value is regarded as the exact color value, which takes into account that a color specification, such as red or blue, is far too inaccurate. As an exact color value, for example, a wavelength specification in nanometers is considered, which is itself subject to a measurement accuracy of, for example, +/- 1 nm when measuring the wavelength, but in the result represents a much more accurate indication than the mere color red or green or blue.

The correction device may be part of an electronic component, which is preferably arranged in the luminaire. The correction device can automatically process the data record and thus take into account the information about the exact color values and the maximum luminous fluxes.

According to an advantageous embodiment of the invention, the correction device may also be part of an operating device for at least one light source. Thus, an operating device, for example, an electronic ballast, for the light source, which may optionally also control a plurality of bulbs, a corresponding electrical component, such as a μ-processor containing, which has the correction means and a correction of incoming to the lamp control signal for driving the bulb can make automatically.

In particular, if an operating device has its own controller, this controller can also represent the correction device and take over the correction function.

In an alternative embodiment of the invention, the correction device is assigned to the controller, so that the controller sent via a signal line to the lamp control signals reach the lamp already in a corrected manner, because the correction is made in the controller.

The invention further relates to a lamp according to the preamble of claim 37 and in turn is based on a lamp according to the preamble of claim 32, as it has become known by the applicant by public prior use.

This invention has the object, a luminaire according to the preamble of claim 37 further develop such that in a simple manner exact mixed colors can be generated.

The invention solves this problem with the features of claim 37, in particular with those of the characterizing part, and is accordingly characterized in that the luminaire has a memory in which a data set contains information about the exact color values of the individual luminous means and / or containing information about the maximum luminous fluxes of the individual luminous means are inscribed, wherein a device for generating color-mixed light distributions is provided, which generates a specific, exact mixed color by controlling the individual luminous means, taking into account the exact color values and / or the maximum luminous fluxes.

The principle of the invention consists essentially in that a device for generating color-mixed light distributions is provided which generates a specific, exact mixed color by controlling the individual lamps, wherein the exact color values of the individual lamps and / or their maximum luminous fluxes are taken into account. The exact color values and the maximum luminous fluxes are written directly or as a data set which describes the exact color values and / or the luminous fluxes of the individual luminous means in a memory of the luminaire. For this purpose, the exact color values and / or the luminous fluxes of the individual luminous means are measured beforehand. The memory is typically described at the factory.

The device for producing color-mixed light distributions can use this data set. This makes exact mixed colors possible.

The device for producing color-mixed light distributions can be arranged in the luminaire or be part of a controller connected to the luminaire via a signal line.

In the event that this device is associated with the lamp, there is a particular advantage when the lamp is a memory in which a data record is stored with information about a plurality of available, exact mixed colors. This embodiment of the invention, by arranging this memory, which may be a separate memory or uses a same memory space as the dataset, allows for recourse to a plurality of previously defined exact mixing colors from which one or more exact mixing colors can be selected and generated by the device can be. In the simplest case, the lamp has a memory in which in addition to the record also a number of previously defined, ie factory defined exact mixed colors is arranged, wherein an adjustment can be provided, for example in the manner of a rotary switch, in particular in the manner of a Farbpotentiometers, the one Setting the predefined colors allows. According to the invention, the predefined colors are exact mixed colors, ie they take into account the exact color values and / or luminous fluxes of the individual luminous means which have previously been obtained by measurement.

The invention further relates to a device for controlling at least one luminaire according to the preamble of claim 40. More particularly, this invention relates to a device for controlling at least one luminaire according to claims 1 to 39.

The invention is based on a control device, as it has become known through public prior use of the applicant.

The object of the invention is to develop a device according to the preamble of claim 40 such that it provides a simplified control of the lights to achieve a color mixed overall light distribution of the lamp.

The invention solves this problem with the features of claim 40, in particular with those of the characterizing part, and is accordingly characterized in that the device taking into account Information about the exact color values and / or the maximum luminous fluxes of the individual illuminants indicates a color space achievable by the luminaire.

The principle of the invention consists first of all in that the exact color values and / or the maximum luminous fluxes of the luminous means of the luminaire are detected, i. be measured and communicated to the device. This can be done, for example, as explained above, according to which the luminaire has a memory in which data records containing information are entered the exact color values and / or the maximum luminous fluxes. In particular, the device can read out the exact color values and / or the maximum luminous fluxes or a data record which describes these values via a signal line which connects the device to the luminaire and subsequently take them into account. The device can be made known about the exact color values and luminous fluxes but in principle also in other ways.

Since the device knows the exact color values and luminous fluxes of the individual illuminants, it can display a color space that can be reached by the luminaire. A color space achievable by the luminaire represents a group of color-mixed total light distributions, that is, several different colors that can actually be reached by this luminaire. While theoretically, by mixing light from a red, a green, and a blue light bulb, virtually all colors can be mixed in infinitely fine graduations, with a real light, due to the exact color values and the maximum light fluxes of the individual bulbs, only a subset may be possible of all possible colors. The actually achievable color space is thus possibly also infinitely large with an infinitely fine, gradual activation, but still smaller, than a theoretically possible color space, which does not take into account exact color values and maximum luminous fluxes of the luminous means.

The device displays the actually achievable color space, for example in the form of a standard color chart, as a color wheel, as a color palette or as another diagram, which allows the selection of colors comfortably. Significantly, an operator or a user of the device will only be shown the colors that the device can actually actually generate, with high color fidelity achieved because the displayed color displayed, for example, on a screen of the device is actually also exactly and identically corresponds to the color, which can produce the lamp as a color mixed overall light distribution.

The fact that the user is immediately displayed, which actual colors are available, the selection of colors can be made easier.

According to an advantageous embodiment of the invention, the device contains information about a sub-color space, which represents a real subset of the achievable color space. This embodiment of the invention provides that a sub-color space, i. a subset of the group of actually achievable colors of the luminaire is formed. This sub-color space is a true subset of the achievable color space and can be displayed to the user. The sub-color space contains, for example, colors to create special color moods. The user can access this sub-color space directly. This makes sense, for example, if an operator wants to allow only very specific color ranges, such as pastel shades or favorite shades, or those mixed shades which are typical for the operator of the device, e.g. corporate identity colors or the like. Also, special colors that match certain color moods can be achieved.

Under color spaces are particularly advantageous when certain special colors are desired in certain applications, for example in the shop lighting, where it is also on Color fastness arrives, so that a customer who looks at a garment in a particular color, is not surprised if this garment shows in daylight outside the shop area in a different color. Also for the simulation of certain color situations, for example in connection with cosmetic advice or the like, the definition of a particular sub-color space and the display capability of a sub-color space may be advantageous.

Further advantageously, it can be provided that the sub-color space is displayed in the manner of a template projected onto the achievable color space. Such a template may, for example, be a continuous curve or area which is projected onto the entire accessible color space by the display device, preferably in an overlapping representation. This allows a lighting designer in particular a quick overview of the ratio of the sub-color space to the achievable color space.

Further advantageously, the device may comprise a memory having a group of several sub-color spaces. From this group can be selected by an operator further advantageously a particular sub-color space. This allows a factory definition of certain sub-color spaces that allow comfortable adjustment of color mixed total light distributions by an operator, for example by a lighting designer, after installation of the device on site and allow a uniform lighting situation, for example, at different locations of a company, to obtain identical colors ,

Finally, the invention also relates to a luminous means for a luminaire according to the preamble of claim 46.

Such a luminaire for a lamp is known and widely used and may be formed for example by a fluorescent lamp, an LED or any other light source. The light source is used in a luminaire and is mounted for this purpose, for example, within a luminaire housing, or to a luminaire.

The object of the invention is to develop the known light source according to the preamble of claim 1 such that an improved control of the light source is possible.

The invention solves this problem with the features of claim 46, in particular with those of the characterizing part, and is accordingly characterized in that the lamp is associated with a memory in which a record is writable.

The principle of the invention thus consists essentially in allocating a memory to the light source. This means that the memory can be arranged or attached directly to the light source. For example, the memory may be arranged on a structural unit which carries the lighting means, e.g. on a mounting plate, a circuit board or on a socket body for the bulb. Alternatively, the memory can also be disposed as detachable from the light source data carrier releasably relative to the light source. For example, For example, a data carrier such as CD-ROM, RFID (radio frequency identifying tag) or the like can be supplied with it when purchasing a light source.

The memory is preferably an electronic memory which contains a data record which describes a property of the luminous means. Preferably, a property of the luminous means is stored as a data record which describes a maximum permissible luminous flux of the luminous means and / or an exact color value, that is to say a precise designation of the color value emitted by the illuminant during operation or of a color spectrum. Alternatively or additionally, information about an aging-dependent behavior or a temperature-dependent behavior of the luminous means can also be written into the memory.

In the event that the memory is directly associated with the lamp and, for example, part of a lamp-carrying unit, e.g. a board is, the memory can be read, for example, after mounting the lamp, or the unit in the light. The readout can either be done by an existing in the lamp electronic component or / and by a controller that is connected to the lamp via a signal line, performed. The reading of the data record allows the lamp, or the controller, to carry out a correction of control signals and to achieve the previously described advantages, which have been described in connection with a luminaire or with a device for controlling luminaires, alike. The lighting means may also be associated with a correction device which, taking into account the data record, carries out a correction of control signals obtained.

Incidentally, the claims relating to a luminous means 46 to 57 are best understood in consideration of the statements made above, so that reference is made to the corresponding text passages to avoid repetition and also for the purpose of reference to one or more features.

It should be noted that the proposed memory, which is associated with a light source, can provide the previously described memory of a luminaire or can replace it or supplement it. In the event that the lamp has a memory which is arranged separately from the memory of the luminous means, a transmission of the memory contents of the luminous-energy store to the memory of the luminaire lends itself. In the event that the memory of the lamp represents or replaces the memory present in the luminaire, no additional memory beyond the memory of the luminous means is required.

On the one hand, the luminous means according to the invention makes possible a simplified factory assembly, since a measurement of the properties of the Bulb can be omitted in the manufacture of the lamp and can already be made by the lamp manufacturer. As a result, steps can be omitted in the lighting manufacturer, since only the reading of the memory of the lamp must be performed. On the other hand, the luminous means according to the invention also enables an unproblematic replacement of bulbs of defective bulbs of a luminaire according to claims 1 to 39, so that a replacement illuminant, which is assigned a memory having a data set containing information about properties of the luminous means, this record for the previously described color compensation or Color correction can provide.

First, a first embodiment of the lamp according to the invention will be explained with reference to FIG. 1, which is designated in the figures in their entirety by 10. It should be noted that in the following description of the figures, even for different embodiments, identical or comparable parts or elements have been designated for clarity with the same reference numerals, partially with the addition of small letters and partly with the addition of additional Arabic numbers or an apostrophe.

Fig. 1 shows a signal line 11, to which a first lamp 10 and a second lamp 10b is connected. The signal line can be, for example, a two-wire 24 V control line, which can transmit signals according to the DALI protocol. Alternatively, however, any other signal lines, depending on the type of protocol used, are used, for example, DMX protocols, TCP / IP controls, EIB (European installation bus) systems, LON (local operating network) -BUS Systems or lighting control buses of other lighting manufacturers can be used.

The signal line 11 is connected to a controller 12 which can send out the control signals and send them to the individual lamps 10, 10b. Optionally, the transmission of the control information can also be bi-directional.

The number of lights 10, 10b connected to the controller 12 depends on the control system used and, for example, in the case of the DALI control system, 64 subscribers per controller 12. If necessary, a plurality of controllers 12 can also be provided.

For simplicity, in the following description of embodiments of the invention, it is assumed that it is a DALI control system with a two-wire signal line 11 and from a controller 12 which can emit control signals according to the DALI protocol, wherein the reader from the However, it is clear from the previous explanations that other control systems can also be used.

The luminaire 10 has, preferably within a luminaire housing, not shown, a lighting means 13, an operating device 14 for the lighting means 13 and an electronic component 15.

The signal line 11 is connected via a section 16 to the separate electronic component 15. The component 15 is connected via a portion 17 of a control line to the operating device 14, and the operating device 14 is connected via a line 18 to the lamp 13.

In the exemplary embodiment of FIG. 1, the operating device 14 is a DALI operating device, that is to say an operating device which fulfills the requirements of the DALI protocol. It should be noted that any other operating devices can be used.

A power supply line 19 supplies the lights with an operating voltage of e.g. FIG. 1 shows, for the sake of simplicity, only a section of the power supply line 19 which supplies the luminaire 10, wherein it is clear that the controller 12, the luminaire 10b and further luminaires, not shown, are preferably connected in common to the voltage supply line 19.

Within the luminaire 10, a first section 20 of the voltage supply line 19 supplies the operating device 14 with operating voltage. The line 18, which connects the operating device 14 with the lighting means 13, supplies the lighting means 13 with operating voltage, wherein the power supply of the lighting means 13 takes place in a controlled manner by the operating device 14.

A further section 21 of the voltage supply line can also supply the electronic component 15 with operating voltage.

In an embodiment of the invention, not shown, a power supply of the separate electronic component 15 can also be done via the operating device 14, so that in this case the line section 21 could be omitted and a line would run from the operating device 14 to the device 15.

Alternatively, it is also possible to supply the device 15 with an operating voltage, which receives the device 15 directly from the voltage applied via the signal line 11 and 16 control signal. In this case, the arrangement of an accumulator in the device 15, for storing the energy is recommended.

In accordance with the invention, the component 15 has a memory 22, which is shown only schematically in FIG. This memory 22, for example an EEPROM, is described with a data record which describes a property of the luminous means 13, in particular contains a measured value of a parameter of the luminous means 13.

In particular, the memory 22 contains information about the maximum luminous flux that the luminous means 13 can emit. Alternatively or additionally, the memory 22 contains information about the exact color emitted by the luminous means 13 and which is also present as a measured value. Both measured values are written into the memory 22 in the factory during the manufacture of the luminaire 10. This information is now available to the electronic component 15 as a basis for a correction or adaptation of the control signals which the component 15 contains from the controller 12.

It should be noted that the component 15 is connected upstream of the operating device 14. The controller 12, for example, is not informed that the lamp 10 has a separate component 15, believes to send their control information or control signals directly to the operating device 14.

If, for example, the information is inscribed in the memory 22 that the luminous means 13 can generate a maximum luminous flux of 70%, this information can be used for a correction of the signal, which is described below. However, it should first be pointed out that the second luminaire 10b according to FIG. 1 has a second luminous means 13b, from which it should now be assumed that it has the same color as the luminous means 13 in the luminaire 10. The two luminous means 13, 13b are intended furthermore emit blue light, for example. However, the bulb 13b can produce a maximum luminous flux that is 100%. This information about the maximum luminous flux is stored in the memory 22b of the electronic component 15b of the luminaire 10b.

If the two lamps 10, 10b now receive the signal from the controller 12 to produce a maximum luminous flux of 100%, a different control of the two lamps 13 and 13b can take place, although the controller 12 is identical to both lamps 10, 10b Send brightness values, that is, control commands that are to cause the bulbs to output a maximum luminous flux.

The electronic component 15 of the luminaire 10 can now determine, taking into account the data set of the memory 22, that the luminous means 13 can only supply a maximum luminous flux of 70%, which represents the lower limit of a tolerance range of different maximum luminous fluxes, that is to say a minimum current. The electronic component 15 will therefore pass on the input control signal from the controller 12 in the simplest case uncorrected to the operating device 14, so that the associated lamp 13 receives the information to generate a maximum luminous flux, due to the technical characteristics of the bulb 13 such described is 70%.

By referring to the data record in the memory 22b, the electronic component 15b of the luminaire 10b can determine that the luminous means 13b can emit a 100% luminous flux and knows that a correction of the signal contained by the control unit 12 must take place in the sense of damping or dimming. Equally, the electronic component 15b knows that a dimming by a factor of 0.7 or 70% has to occur in order to be able to generate a luminous flux of the luminous means 13b which is identical in comparison with the other luminaires 10. Accordingly, the electronic component 15b performs a correction of the received control signal and sends to the operating device 14b a correspondingly corrected control signal via the signal line section 17b, so that the operating device 14b only dimmed the lighting means 13b and finally the lighting means 13b emits only a 70% luminous flux.

The previous description makes it clear that the electronic component 15, 15b or, if appropriate, a correction device 24 arranged there corrects the control signals received from the controller 12. The correction or adaptation of the control signals takes place taking into account the information contained in the memory 22 or 22b Record. Different components 15, 15b also assume different corrections because the different lamps 13, 13b have different properties.

The function of the component 15, 15b can therefore also be regarded as that of a converter, that is to say of a repeater, with a correction function. The data records remain permanently inscribed in the associated memories 22, 22b, for example, so that the lamps 10, 10b can also be detached from the signal line 11 and, for example, connected to another controller without this information being lost.

A significant advantage of this embodiment is that the controller 12 does not recognize that the data sets are used to correct the control signals. Thus, the luminaires 10, 10b according to the invention can also be connected to any other controllers 12, which according to the same protocol, e.g. according to the DALI protocol, modulate control signals on the signal line 11, and still be achieved the advantages of the invention.

In an alternative embodiment of the invention, the controller 12 can read the memory contents of the memory 22, 22b, wherein the corresponding data sets can be transmitted via the signal line 11. The controller 12 can refer to these records and process the records, for example, to indicate to an operator, which technical properties have the connected lights.

Finally, there is also the possibility that the control center 12, taking into account the transmitted data records from the memories 22 and 22b itself sends corrected signals to the lights 10, 10b. In this case, however, the electronic components 15, 15b may not carry out any further correction of the control signals obtained, since the different components 15, 15b have already corrected different ones in this case Control signals received. Accordingly, it is possible to design the electronic components 15, 15b such that, once the contents of the memories 22, 22b have been read out by a controller 12, they suppress or cancel the correction function and forward the incoming signals to the operating unit 14 unchanged ,

In the previously described embodiment of FIG. 1, it has been assumed that the electronic component 15 is a separate component from an operating device 14 contained in the luminaire 10. However, the embodiment of FIG. 2 is intended to make it clear that the memory 22 does not necessarily have to be provided by a separate component 15.

FIG. 2 shows in a representation similar to FIG. 1 a schematic block diagram, with two lights 10c and 10d, each having a lighting means 13c and 13d, which is connected via a voltage supply line section 18c and 18d with an associated operating device 14c and 14d , The respective operating device is connected via a signal line section 16c or 16d to the signal line 11 which connects the lights 10c and 10d to a controller 12.

The structure of the power supply line 19 according to FIG. 1 is not discussed in detail in FIG. 2. The viewer of Fig. 2, however, it is clear that a comparable power supply of the lights 10 c, 10 d is provided, where there for the sake of clarity, only the signal line 11 is shown.

The memory in which the data record is written, which describes a property of the associated light source 13c or 13d, is now a memory 22c or 22d of the existing operating device 14c or 14d. The operating device 14c, 14d is a DALI operating device, which has a light scene memory according to the definition of the DALI protocol. This can be described, for example, with the data record. Others too, Memory available in the operating device 14c or 14d can be described with the data record or with the data records.

In contrast to the exemplary embodiment of FIG. 1, in the exemplary embodiment of FIG. 2 no correction of the control information received by the controller 12 takes place in the luminaire 10c or 10d. Instead, after connecting the lights 10c and 10d to the signal line 11 from the controller 12 during an initialization or in a subsequent process step of the memory contents of the memory 22c and 22d read and transferred the record or records to the controller 12. The controller 12 may subsequently send corrected control information to the individual lamps 10c or 10d taking into account the data records, so that the goal described with reference to FIG. 1, for example a uniform brightness of the different lamps 10c, 10d, is achieved in an analogous manner.

FIG. 3 shows a further exemplary embodiment of a luminaire 10e according to the invention in a schematic, block diagram-like illustration, comparable to FIG. 1. Again, a separate electronic component is designated by 15e, which has a memory 22e. In addition, an operating device 14e is arranged in the luminaire, to which three different luminous means 13e1, 13e2 and 13e3 are connected, which are formed, for example, by a red LED, a green LED and a blue LED. The operating device 14e may, for example, be a conventional RGB DALI operating device for three LEDs.

The operating device 14e and the electronic component 15e are supplied with operating voltage via sections 20 and 21 of a voltage supply line 19. Analogously to FIG. 1, the electronic component 15e is connected via a section 16 to the signal line 11 and above to a controller 12. Comparable lights 10e 'and 10e "are also connected to the signal line 11.

In the memory 22e of the electronic component 15e, one or more data sets are stored which, instead of or in addition to the maximum luminous fluxes of the individual luminous means 13e1, 13e2, 13e3, can also contain the exact color values of the luminous means 13e1, 13e2 and 13e3, for example in the form of can actually be measured in nanometers wavelength actually emitted by these Leuchtmittel. For example, in the manufacture of the lamp can be determined 10e that the blue lamps 13e3 having a wavelength le3 that the green lamps 13e2 having a wavelength le2 and that red lamps 13e1 a wavelength le ₁ has.

The red, green and blue light sources of the luminaire 10e ', which are not shown in FIG. 3, can emit, for example, different wavelengths, which may differ from the wavelengths le3, le2 and le1.

For example, LEDs of green color may vary between 505 nm and 515 nm, this value being merely exemplary. For example, while the green LED 13e1 of the luminaire 10e emits green light of wavelength 515 nm, the corresponding green LED of the luminaire 10e 'not shown in FIG. 3 could emit green light of the wavelength 505 nm. The lamp 10e 'and other lights that are connected to the same signal line 11, in turn, can easily produce different green values.

Likewise, the red and blue LEDs may have different values. Finally, lamps that also have other colored lamps, for example, in addition to a red, a green and a blue LED also have a white and / or a yellow LED and / or a cyan and / or an amber LED, vary accordingly.

While the color variations are less problematic when only monochromatic lights are considered, so do too small color differences in the order of magnitude of individual nanometers and deviations in the maximum luminous flux to a greater extent then noticeable when color mixtures take place, as they are possible with lamps according to FIG. 3.

If the luminaire 10e is controlled, for example, by the controller 12 via the signal line 11 in such a way that the luminaire 10e is intended to produce a mixed color of a specific color, then in a conventional controller 12 the luminaire 10e receives a correspondingly composed signal, which is sent to the operating device 14e and causes the three bulbs 13e1, 13e2 and 13e3 to be driven accordingly. If the lights 10e 'and 10e "produce the same color, these lights receive from the controller 12 an identical control signal.

In the luminaire 10e according to the invention according to FIG. 3, a data record is stored in the memory 22e of the component 15e which describes the exact light color and the maximum luminous fluxes of the individual luminous means 13e1, 13e2, 13e3. This can either be an immediate information of the light colors and luminous fluxes actually emitted by the individual illuminants. Alternatively, however, this information may be expressed as a deviation from a standard value, or in an alternative manner in the form of a correction factor.

If the luminaire 10e now receives the signal, for example from the controller 12, to produce a specific mixed color, then the electronic component 15e, knowing the exact color values and the maximum luminous fluxes of the three luminous means 13e1, 13e2, 13e3, can correct the control signals obtained and three illuminants 13e1, 13e2, 13e3 via the operating device 14e in a corrected manner, so that the lighting means 13e1, 13e2, 13e3 together generate as a result of the corrected drive exactly the light color that was intended to produce by the controller 12.

In this way, despite different color values and different maximum luminous fluxes of the luminous means contained in the three luminaires 10e, 10e ', 10e ", it is possible for the three different luminaires to actually emit the same colored light.

The exact mechanism of the correction using a correction matrix will be explained below. However, it should already be noted at this point that the luminaire 10e according to FIG. 3 shows an electronic component 15e in which, in addition to the memory 22e, a separate component 24e is arranged, which represents a correction device. This correction device, which receives the control signals which the luminaire 10e receives from the controller 12 so that subsequently the corrected values can be forwarded to the operating device 14, can be formed by a separate electronic component and in particular contain a μ-processor. Alternatively, however, the memory 22e and the correction device 24e may also be formed by a common component 15e, as shown in FIG.

In addition, it is pointed out that a corresponding correction device 24 is also shown in FIG. 1, it being clear to the person skilled in the art that such a correction device can also be used in all other illustrated and not illustrated exemplary embodiments.

However, it should first be noted that a correction by the electronic component 15e can also take place, for example, if only the signal is transmitted from the controller 12 via the signal line 11 to the lamp 10e that the lamp 10e should generate red light. If the light color emitted by the light source 13e1 does not correspond exactly to the desired light, but if it varies, for example, by a few nanometers, a correction of this light can also take place by adding slight green or blue light components through the light sources 13e2 or 13e3.

It should be noted that Fig. 3 shows an embodiment which operates with a separate electronic component 15e in the manner of the embodiment shown in Fig. 1 with an electronic component 15. In analogy to FIG. 2, however, the function of the memory 22e can also be incorporated into the operating device 14e with a luminaire 10e having a plurality of luminous means 13e1, 13e2, 13e3 of different color. Such an embodiment is not shown for reasons of clarity.

Equally, the memory 22e of the electronic component 15e can also be made readable by the controller 12, wherein in the case of reading and transmission of the data set, in turn, the correction function of the electronic component 15e should be switched off.

Fig. 3 also shows a sensor 23 for detecting a temperature. For example, the ambient temperature of the luminaire 10e, but alternatively, for example, also a chip temperature of the LED chip can be measured. Finally, it is also possible to measure different temperatures of the individual lamps 13e1, 13e2, 13e3.

Since it is known that the ambient or operating temperature of the individual lighting means, in particular in the case of LEDs as lighting means, influences the operation of the LED itself, knowledge of the existing temperature of the lighting means can also be used to correct or adapt the control of this lighting means. For this purpose, a data record which describes the temperature-dependent behavior of the individual light sources 13e1, 13e2, 13e3 can also be stored in the memory 22e. Since often the exact operating temperature can not be determined, but this temperature results to a certain extent also from the currents flowing through the LED before the measurement time or from the current load in combination with the ambient temperature, the electronic component 15e may also have a device be assigned to the current or the previous in the last Moments, for example, in the last 30 s or 60 s carried out control of the different bulbs 13e1, 13e2, 13e3 considered, in knowledge of the current or the past control can be closed to the current temperature and stored in the memory 22e temperature-dependent behavior of the individual Bulb can be considered in a correction of the control signals in an optimized manner.

One or more temperature sensors 23 can also be used in the same way in the other embodiments.

Finally, it is also possible to provide an operating hours counter in the electronic component 15e which, as it were, notices which lamp of the associated lamp (for example 10e) is loaded in which way. For this purpose, the memory 22e can contain a further data record which knows the aging-dependent behavior of the individual lighting means. Correction by the component 15e can now again take place in such a way that an adjustment of the signals received from the controller 12 via the signal line 11 is carried out with knowledge of the hours of operation of the individual lamps and corrected control signals from the electronic component 15e are sent to the operating unit 14e become.

With knowledge of the temperature-dependent behavior of the lamps and / or with knowledge of the aging-related behavior of the lamps, a high color fastness of the lamp can also be ensured over different temperature ranges and / or over a very long period of time.

Similarly, in embodiments not shown may also be provided that the records relating to the temperature-dependent and aging-dependent behavior of the bulbs are transmitted via the signal line 11 to the controller 12 and this memory 22e is read out.

Furthermore, it can be provided that a data set on the temperature-dependent or aging-dependent behavior of the lamps is already included in the controller 12 and, for example, in the context of an initialization process, the controller 12 of the lights (eg 10e) only informed which lamps in the Lamp are included.

FIG. 3 furthermore shows that a further memory 25e is arranged in the electronic component 15e. This memory 25e serves to receive a mix record, i. Information about several, available for selection, exact mixed colors. An exact mixed color is defined as a color which results from mixing the colors generated by the individual luminous means, this mixture taking into account the exact color values and / or the maximum luminous fluxes of the individual luminous means 13e1, 13e2, 13e3. Exact mixed colors, or a mixed data set containing a plurality of these exact mixed colors, is written into the memory 25e at the factory. A selection can be made, for example, via a schematic device, designated by 26 in FIG. 3, which can be designed, for example, in the manner of a color potentiometer and, for example, can provide 12 adjustable colors. Also push button od. Like. Can be provided.

The advantage of such a device 26 for setting an exact mixed color is that several different lights can contain the same mixed data sets, so that taking into account the different exact color values and the different maximum luminous fluxes of the different bulbs of different lights a user in a simple way Possibility to have multiple lights produce an identical exact light color.

The skilled person will appreciate that the memory 25e and the memory 22e may also be formed by a common memory.

Likewise, it will be appreciated that the device 26 for adjusting a mixed color together with the reservoirs 22e and 25e and optionally together with the correction device 24e and any other devices of the device 15e, not shown, constitutes a device for producing color-mixed light distributions.

The device 26 may under certain circumstances be addressed by the controller 12, alternatively, but also be manually adjustable and produce the desired, exact mixed color, without the need for a control signal of a controller 12 requires.

Advantageously, the data record written in the memory 22, 22b, 22c, 22e contains information about both the maximum luminous flux and the exact color value. Depending on the type of lamp 10 arranged in the luminaire, however, it may also be sufficient to write information into the memory via only one of the two indications. For example, an indication of the exact color value is sufficient if the illuminant in question varies greatly with regard to the color value, but only varies very slightly with respect to the maximum luminous flux.

In the opposite case, that is, when there is a strong variation of the luminous flux at the different LEDs, but these practically do not vary in terms of their color value, it may be sufficient to write into the memory a record containing only information about the maximum possible luminous flux.

Finally, depending on their nature, different light sources can also have different age-dependent and temperature-dependent behavior. Then, if this arrest has a strong effect on the luminous flux or on the exact color value, it is advisable to include in the dataset information about this behavior or this behavior in the event of a correction of the actuation signals consider. If the temperature-dependent or aging-dependent behavior practically has no effect on luminous flux and color value, this behavior can be disregarded.

4, a further embodiment of a luminaire 10f according to the invention will now be explained with reference to FIG.

Fig. 4 shows a lamp 10f, which is connected in a conventional manner to a common signal line 11, wherein comparable to a representation according to FIG. 2, the associated power supply line is omitted for clarity. The lamp 10f consists of two partial lamps 10f1 and 10f2, each having three colored lamps. The partial luminaire 10f1 holds a red lamp 13f11, a green lamp 13f12 and a blue lamp 13f13. The lighting means can be formed by LEDs as well as the three light sources 13f21, 13f22 and 13f23 of the second part light 10f2.

Each partial light 10f1, 10f2 contains its own operating device 14f1 or 14f2, which may be, for example, a DALI-RGB Vorschaitgerät.

The peculiarity of this luminaire 10f now consists in that a common electronic component 15f is provided for both partial luminaires 10f1, 10f2, which may also be arranged separately, ie, for example, at a distance from one another, which has a memory 22f. The memory 22f contains a data record which contains the properties of the different luminous means 13f11, 13f12, 13f13, 13f21, 13f22, 13f23 of the different partial luminaires 10f1 and 10f2 and contains, for example, the exact color values and / or the maximum luminous fluxes of the individual luminous means. The electronic component 15f may moreover have its own DALI address and thus be recognized by the controller 12 as a separate subscriber. In this case, the component 15f may be responsive to the controller 12 like a conventional DALI operating device. However, the electronic component 15f has the peculiarity that it does not simply forward the control signals contained by the controller 12, but corrected to both operating devices 14f1 and 14f2 of the two part lights 10f1 and 10f2 retransmitted. The correction is dependent on the illuminant and is typically different for the two sets of light sources in the two part lights 10f1 and 10f2.

If the electronic component 15f receives, for example, a control signal from the controller 12, according to which a specific light color is to be generated, an appropriate forwarding of the partial illumination 10f1 and 10f2 can be effected as a result of individual correction and adaptation to the actual exact color values and maximum luminous fluxes of the individual luminous means corrected control signals to the operating devices 14f1 and 14f2 done so that the two different partial lights 10f1 and 10f2 actually produce exactly the same light color. In this case, the electronic component 15f can also address or manage a plurality of operating devices 14f1, 14f2, so that virtually a subsystem of a DALI network can connect to the output side of the component 15f. Since the electronic component 15f has only one address in the DALI network, a very large number of lamps, which would be limited to only 64 users without a component 15f, can thus be achieved in the DALI network.

However, such an arrangement, according to which an electronic component 15f serves to save DALI addresses in the overall DALI network and to supply a plurality of operating devices 14f1, 14f2, is particularly advantageous when the electronic component 15f ensures that the luminous means of the individual Partial lights 10f1 and 10f2 should generate substantially the same light color.

Fig. 4 also shows that the device 15f may be equipped with two or more different temperature sensors 23f1 and 23f2, which measure and take into account the different temperatures. In this respect, a correction due to the temperature-dependent behavior of the individual lamps in the manner described above can take place.

Fig. 5 first shows a standard color chart, as known to those skilled in the field of lighting technology and as described for example in the manual for lighting, Lange, publisher; German Phototechnical Society, 4th edition, 1996, I. page 16 is shown and has been executed.

Without explaining at this point the basic principle of a standard color chart, which is assumed to be known, it is indicated that the standard color chart represents a substantially triangular area, the red color in the right corner area 27, and blue color in the lower right area 28 having 29 green color in an upper edge region. A central area 30 contains substantially white light. The unspecified intermediate areas contain mixed colors that result from mixing of the individual primary colors.

The standard color chart shows all theoretically possible colors of an ideal luminaire with three ideal illuminants.

A real blue light source, for example a blue LED of a luminaire, emits, as stated above, different exact color values. The crosses 31 indicated in the region 28 of FIG. 5 represent a group of measuring points which have been measured on different blue LEDs, as are typically supplied by the LED manufacturer to a luminaire manufacturer. Since these measured values lie in different places in the color triangle of the standard color chart, not even the entire color space of the color chart according to the area 32 can be achieved by mixing with light of a red, a green LED, which are also present in the same luminaire and differ equally but only a limited, in Fig. 5 by way of example triangular indicated reachable color space 33. The achievable color space is therefore significantly limited compared to the theoretically possible color space. This achievable color space 33 is different for each lamp due to the different color values of the individual lamp and provides the totality of the color mixed total light distributions actually achievable by the luminaire.

The device 12 for controlling, in particular, a plurality of luminaires 10e according to FIG. 3 or other luminaires now has, in one exemplary embodiment, a display device which is denoted by 34 in its entirety in FIGS. 6 and 7. Shown in FIGS. 6 and 7 are only the contents of the display. The display in the manner of a standard color chart was chosen here by way of example again, with other color space representations, for example color circles, color palettes or the like, being possible.

FIG. 6 shows that the display device, for example in the form of a computer screen, represents the actually achievable color space 33 of the associated luminaire. In the event that different lights are connected to the device 12 for controlling a plurality of lights, the device 12 may also perform a comparative study of the different achievable color spaces of the individual lights, and find the lowest common denominator, i. the actually achievable color space 33, which can reach all connected to the controller 12 lights. This color space 33 thus shows in the form of a triangle, according to the display content according to FIG. 6, of the operator all possible mixing colors which can actually be reached by the luminaires.

6 additionally shows five circles 35a, 35b, 35c, 35d, 35e, which are projected in the manner of a template onto the actually achievable color space 33. The five, discrete, i. spaced circles form in the sum of a sub-color space 35, which represents a real subset of the achievable color space 33.

FIG. 7 shows in a representation comparable to FIG. 6 the actually achievable color space 33 and another lower color space 36, which differs from the lower color space 35 according to FIG. The sub color space 36 is a substantially closed sheet of a predetermined contour K, which in turn is a true subset of the actually achievable color space 33. Also, the sub-color space 36 is projected onto the actually achievable color space in the manner of a stencil.

An operator can now advantageously select from a plurality of possible sub-color spaces (e.g., 35 and 36), which are preferably stored in the memory of the device 12, a desired sub-color space.

The operator thus has a very convenient way to create predetermined, exact mixed colors.

Merely in addition, it should be noted that the luminaire according to the invention can be provided with an override line 37 in all exemplary embodiments, as illustrated by the luminaire 10b of FIG. The override line 37 allows recourse to the operating device in the conventional, uncorrected manner, bypassing the electronic component 15b. Such override or random access may be desired, for example, when a user wants to generate the maximum possible luminous flux of the associated luminaire 10b, regardless of the light color generated thereby, or in the event that the user does not place any value on the compensation and correction options.

Furthermore, it should be noted in addition that the luminaire according to the invention, insofar as it provides a separate electronic component 15 with a corresponding memory and in particular ensuring a correction function, can act in the manner of a converter, and in particular DALI control signals in corrected DALI control signals for a downstream operating device can implement. Alternatively, conversions can also be made that perform a protocol translation, in the manner of a gateway, eg from DMX to DALI or from DALI on DMX or from DALI to pulse width modulated signals or from DALI to a LON BUS or an EIB BUS or vice versa. This conversion function is preferably integrated directly into the separate electronic component 15, 15b, 15e, 15f.

In the following, it will be explained how the electronic component 15e of a luminaire 10e according to FIG. 3, in particular how the correction device 24e of the component 15e of the luminaire 10e, can correct the control signals received from the controller 12:

besitzen, wobei die einzelnen Anteile Ir, Ig und Ib jeweils die Stromanteile andeuten, die die drei Leuchtmittel 13e1, 13e2 und 13e3 aussenden sollen. So kann der Stromanteil Ir den Lichtstrom bezeichnen, den das rote Leuchtmittel 13e1 aussenden soll. Es wird deutlich, dass die Stromanteite Ir, Ig und Ib jeweils zwischen 0 und 100 % liegen können, wobei es sich anbieten könnte, und wobei dies auch von dem DALI-Protokoll vorgesehen ist, jeden der drei Werte Ir, Ig und Ib mit acht Bit zu belegen, so dass 256 unterschiedliche graduelle Unterteilungen möglich sind.The signal emitted by the controller 12 and arriving at the device 15e may, for example, take the form of a current vector of the form $$\mathrm{I}=\left(\begin{array}{c}\mathrm{I}\mathrm{r}\\ \mathrm{I}\mathrm{G}\\ \mathrm{I}\mathrm{b}\end{array}\right)$$

possess, wherein the individual proportions Ir, Ig and Ib respectively indicate the current components, which should emit the three bulbs 13e1, 13e2 and 13e3. Thus, the current component Ir can denote the luminous flux which the red luminous means 13e1 is to emit. It can be seen that the current components Ir, Ig and Ib can each be between 0 and 100%, which it could offer, and this is also provided by the DALI protocol, each of the three values Ir, Ig and Ib with eight Bit to occupy, so that 256 different graduations subdivisions are possible.

darstellen lässt, wobei die drei Variablen Or, Og und Ob jeweils den Lichtstrom bezeichnen, den die drei Leuchtmittel 13e1, 13e2 und 13e3 nach Durchführung der Korrekturen tatsächlich emittieren sollen. Die Variable Or bezeichnet den von dem roten Leuchtmittel 13e1 zu emittierenden Lichtstrom. Wiederum können die Werte Or, Og und Ob zwischen 0 und 100 % liegen und entsprechend einer 8-Bit-Auflösung 256 Lichtstromwerte umfassen.The current vector I with the current components Ir, Ig and Ib is thus present as an input signal or input to the component 15e. From the component 15e, an output signal (output) should be output and forwarded to the associated operating device 14e, which is likewise a vector of the form $$\mathrm{O}=\left(\begin{array}{c}\mathrm{O}\mathrm{r}\\ \mathrm{O}\mathrm{G}\\ \mathrm{O}\mathrm{b}\end{array}\right)$$

The three variables Or, Og and Ob respectively denote the luminous flux which the three luminous means 13e1, 13e2 and 13e3 are supposed to actually emit after the corrections have been made. The variable Or denotes the luminous flux to be emitted by the red luminous means 13e1. Again, the values Or, Og and Ob can be between 0 and 100% and include 256 luminous flux values corresponding to an 8-bit resolution.

und enthält somit neun Einträge, für die sich z.B. die folgenden typischen Werte ergeben könnten:The electronic component 15e now automatically performs a correction of the input signal 1 to an output signal O, wherein for the sake of simplicity, a correction of the form O = K * I is made and K represents a matrix. The matrix or the entries of this matrix correspond to the aforementioned data record and contain the information about the properties of the lighting means. The matrix forms, for example, the form: $$\mathrm{K}=\left(\begin{array}{ccc}\mathrm{r}\mathrm{r}& \mathrm{r}\mathrm{G}& \mathrm{r}\mathrm{b}\\ \mathrm{G}\mathrm{r}& \mathrm{G}\mathrm{G}& \mathrm{G}\mathrm{b}\\ \mathrm{b}\mathrm{r}& \mathrm{b}\mathrm{G}& \mathrm{b}\mathrm{b}\end{array}\right)$$

and thus contains nine entries for which the following typical values might result, for example:

The values for rr, gg and bb are ≥ 70% and ≤ 100% if the lamps used are colored LEDs. Likewise, the values rg, rb, gr, gb, br and bg are ≥ 0 and ≤ 5%.

Furthermore: Midestoutput (for example 70%) <(rr + rg + rb) ≤ 100%

The minimum output is, for example, the lowest possible maximum luminous flux of a luminous means.

aufweist. Dies bedeutet, dass von der Steuerung 12 das Signal ausgesandt wird, wonach lediglich das rote Leuchtmittel 13e1 angesteuert werden soll.For clarity, assume that the input signal is the form $$\mathrm{I}=\left(\begin{array}{c}1\\ 0\\ 0\end{array}\right)$$

having. This means that the signal is emitted by the controller 12, after which only the red light source 13e1 is to be activated.

Since the red light source 13e _{1 has} an exact color value, a so-called actual color value, which may deviate from a desired color value, that is to say an ideal red by a few nanometers, the requirement arises for low light components of green or blue light through the light sources 13e2 and 13e3 to mix in order to achieve the desired shade of red, ie the desired color light-mixed total light distribution.

so dass deutlich wird, dass für den Fall, dass die Variablen gr und br von Null verschieden sind, ein Output-Vektor $$\mathrm{O}=\left(\begin{array}{c}\mathrm{r}\mathrm{r}\\ \mathrm{g}\mathrm{r}\\ \mathrm{b}\mathrm{r}\end{array}\right)$$

entsteht, mithin ein Steuersignal als Output an das Betriebsgerät 14e gesandt wird, welches auch Lichtanteile grünen und blauen Lichtes enthält, wenn gr und br ungleich Null sind.The output is calculated according to the formula $$\mathrm{O}=\mathrm{I}*\mathrm{K}=\left(\begin{array}{c}1\\ 0\\ 0\end{array}\right)*\mathrm{K}.$$

so that it becomes clear that in the case that the variables gr and br are different from zero, an output vector $$\mathrm{O}=\left(\begin{array}{c}\mathrm{r}\mathrm{r}\\ \mathrm{G}\mathrm{r}\\ \mathrm{b}\mathrm{r}\end{array}\right)$$

Thus, a control signal is sent as output to the operating device 14 e, which also contains light components of green and blue light, if gr and br are not equal to zero.

From the above it is clear that the variables gr and br indicate additional light components which are to be mixed into the light of the red light source 13e1 in order to produce a specific, predefined, exact red tone.

In other words, the electronic component 15e takes account of an exact color value of the red luminous means 13e1, that is to say an actual value which can deviate from a desired value of the red luminous means 13e1. The correction device 24e or the component 15e can make the desired correction by applying the correction matrix K and produce an exact mixed color.

From the above, it follows that the matrix K contains nine constants, which are typically one byte each, i. 8 bits in size, can be selected.

$$\mathrm{K}\left(\mathrm{T}\right)=\left(\begin{array}{ccc}\mathrm{r}\mathrm{r}\left(\mathrm{T}\mathrm{r}\right)& \mathrm{r}\mathrm{g}\left(\mathrm{T}\mathrm{g}\right)& \mathrm{r}\mathrm{b}\left(\mathrm{T}\mathrm{b}\right)\\ \mathrm{g}\mathrm{r}\left(\mathrm{T}\mathrm{r}\right)& \mathrm{g}\mathrm{g}\left(\mathrm{T}\mathrm{g}\right)& \mathrm{g}\mathrm{b}\left(\mathrm{T}\mathrm{b}\right)\\ \mathrm{b}\mathrm{r}\left(\mathrm{T}\mathrm{r}\right)& \mathrm{b}\mathrm{g}\left(\mathrm{T}\mathrm{g}\right)& \mathrm{b}\mathrm{b}\left(\mathrm{T}\mathrm{b}\right)\end{array}\right)$$

The correction matrix becomes more complicated if, in addition to the consideration of production-related color differences and maximum possible luminous flux differences, a temperature dependence is also taken into account. For this purpose, the output O results from a temperature-dependent correction matrix K (T) and the input signal I according to the formula: $$\mathrm{O}=\mathrm{K}\left(\mathrm{T}\right)*\mathrm{I}.\mathrm{}\mathrm{in\; which}$$

$$\mathrm{K}\left(\mathrm{T}\right)=\left(\begin{array}{ccc}\mathrm{r}\mathrm{r}\left(\mathrm{T}\mathrm{r}\right)& \mathrm{r}\mathrm{G}\left(\mathrm{T}\mathrm{G}\right)& \mathrm{r}\mathrm{b}\left(\mathrm{T}\mathrm{b}\right)\\ \mathrm{G}\mathrm{r}\left(\mathrm{T}\mathrm{r}\right)& \mathrm{G}\mathrm{G}\left(\mathrm{T}\mathrm{G}\right)& \mathrm{G}\mathrm{b}\left(\mathrm{T}\mathrm{b}\right)\\ \mathrm{b}\mathrm{r}\left(\mathrm{T}\mathrm{r}\right)& \mathrm{b}\mathrm{G}\left(\mathrm{T}\mathrm{G}\right)& \mathrm{b}\mathrm{b}\left(\mathrm{T}\mathrm{b}\right)\end{array}\right)$$

This matrix shows that the individual nine contents of the matrix K (T) are temperature-dependent. The temperature-dependent behavior of these values should therefore be known, at least approximately known.

The temperature Tr is, for example, the temperature of the red lamp, the temperature Tg is the temperature of the green lamp, and the temperature Tb is the temperature of the blue lamp.

Under certain circumstances, it is sufficient to measure a common ambient temperature, for example a board temperature, wherein only a single temperature measurement value M is available. Knowing the channel output O and the temperature measured value M, it is possible to deduce the actual temperature of the individual lamps (red, green, blue).

wobei $$\mathrm{O}=\mathrm{K}\left(\mathrm{A}\right)\ast \mathrm{I}.$$

Die Werte Ar, Ag und Ab, d.h. die Alterungen eines Leuchtmittels, ergeben sich aus einer Integration des zugehörigen leuchtmittelabhängigen Output-Signals über die Zeit. Insofern erfolgt eine Zwischenspeicherung der einzelnen Outputs integriert über die Zeit.Finally, the correction matrix K may additionally also contain a correction function that takes into account the aging dependence of the light generation of the individual lighting means. This results in a correction matrix that takes into account the aging-dependent behavior $$\mathrm{K}\left(\mathrm{A}\right)=\left(\begin{array}{ccc}\mathrm{r}\mathrm{r}\left(\mathrm{A}\mathrm{r}\right)& \mathrm{r}\mathrm{G}\left(\mathrm{A}\mathrm{G}\right)& \mathrm{r}\mathrm{b}\left(\mathrm{A}\mathrm{b}\right)\\ \mathrm{G}\mathrm{r}\left(\mathrm{A}\mathrm{r}\right)& \mathrm{G}\mathrm{G}\left(\mathrm{A}\mathrm{G}\right)& \mathrm{G}\mathrm{b}\left(\mathrm{A}\mathrm{b}\right)\\ \mathrm{b}\mathrm{r}\left(\mathrm{A}\mathrm{r}\right)& \mathrm{b}\mathrm{G}\left(\mathrm{A}\mathrm{G}\right)& \mathrm{b}\mathrm{b}\left(\mathrm{A}\mathrm{b}\right)\end{array}\right).$$

in which $$\mathrm{O}=\mathrm{K}\left(\mathrm{A}\right)*\mathrm{I},$$

The values Ar, Ag and Ab, ie the aging of a luminous means, result from an integration of the associated illuminant-dependent output signal over time. In this respect, an intermediate storage of the individual outputs is integrated over time.

The consideration of the production-related color and luminous flux differences and the temperature- and age-dependent differences finally leads to a temperature- and age-dependent correction matrix $$\mathrm{K}\left(\mathrm{T}.\mathrm{A}\right)=\left(\begin{array}{ccc}\mathrm{r}\mathrm{r}\left(\mathrm{T}\mathrm{r}.\mathrm{A}\mathrm{r}\right)& \mathrm{r}\mathrm{G}\left(\mathrm{T}\mathrm{r}.\mathrm{A}\mathrm{r}\right)& \mathrm{r}\mathrm{b}\left(\mathrm{T}\mathrm{r}.\mathrm{A}\mathrm{r}\right)\\ \mathrm{G}\mathrm{r}\left(\mathrm{T}\mathrm{G}.\mathrm{A}\mathrm{G}\right)& \mathrm{G}\mathrm{G}\left(\mathrm{T}\mathrm{G}.\mathrm{A}\mathrm{G}\right)& \mathrm{G}\mathrm{b}\left(\mathrm{T}\mathrm{G}.\mathrm{A}\mathrm{G}\right)\\ \mathrm{b}\mathrm{r}\left(\mathrm{T}\mathrm{b}.\mathrm{A}\mathrm{b}\right)& \mathrm{b}\mathrm{G}\left(\mathrm{T}\mathrm{b}.\mathrm{A}\mathrm{b}\right)& \mathrm{b}\mathrm{b}\left(\mathrm{T}\mathrm{b}.\mathrm{A}\mathrm{b}\right)\end{array}\right)$$

Preferably, the correction means 24e takes this correction matrix into account, and converts the control signals received from the controller 12 in accordance with the input vector 1 by multiplication with the matrix of K (T, A) into an output signal O which is sent to the operating unit 14e.

As previously described, application of the matrix may also be done directly in the controller 12, e.g. the matrix values of the production-related matrix K, i. a non-temperature and non age-dependent matrix, have been transferred as a result of a read-out of the memory of the lamp to the controller.

Alternatively, only a part of the matrix correction, for example only the correction based on the aging-related behavior or based on the temperature-related behavior, by the controller, whereas a correction taking into account the maximum luminous flux and the exact color values only in the luminaire.

8 shows a schematic, fragmentary, partially sectioned side view of an exemplary embodiment of a luminous means 13g according to the invention, which is formed, for example, by an LED, as shown schematically in FIG. 8, by an SMD (= surface mounted diode) LED. The lighting means 13g is attached to a circuit board 38. On the board 38 is a memory 22g into which a data set, e.g. a matrix which contains entries which describe the properties of this luminous means 13g is inscribed. The light propagation of the LED is shown in FIG. 8 only indicated by schematic arrows.

It is clear to the observer that the lighting means 13g together with the circuit board 38 and with the memory 22g forms a manageable unit which can be fixed in a luminaire. The memory 22g may be electrically connected to the lighting means 13g via printed conductors, not shown, on the circuit board 38. In this case, the memory 22g, typically of an electrical component, more preferably containing a μ-processor, is formed, also be associated with a drive unit for the lighting means 13g.

The lighting means 13g may be a single-color LED or may also be provided by a plurality, possibly also differently colored LEDs.

If the memory 22g is electrically connected to the light source 13g, it suffices to provide the unit designated overall by 39 in FIG. 1 with a pair of connecting leads, not shown, which are connected to a light, not shown in FIG. 8, for example a light 10 According to FIG. 1, can be connected.

In the event that the memory 22g is not electrically connected to the lighting means 13g, separate connections or supply lines can be provided which connect the memory 22g and, separately from this, the lighting means 13g to elements of the light 10.

In the memory 22g is written in a manner previously described according to the embodiments of Figures 1 to 4 or in a similar manner, a record, which also allows a correction of control signals. The difference now is that the memory 22g is associated with the lighting means 13g. The memory content 22 g can either be read out so that the correction function is performed by a correction device which is arranged in the luminaire but separate from the assembly 39. Alternatively, the controller 12, for example, according to FIG. 1, take over the correction function. Finally, it is also possible to assign a correction device 24g according to FIG. 8 to the light source 13g and to arrange this correction device 24g directly on the structural unit 39 which carries the light source 13g. Correction device 24g and memory 22g may also be part of a single electronic component in the exemplary embodiment which is not shown, which may comprise, for example, a μ-processor and an EEPROM memory.

The memory 22g, which is associated with the lighting means 13g, can also be arranged structurally separate from the lighting means 13g and from the building unit 39 and, for example, as a data carrier enclosed with the lighting means 13g, e.g. in the form of a CD-ROM or in the form of an SD card, with which bulbs 13g or with the unit 39 are supplied. In this case, the lighting means 13g and the memory 22g form an allocation unit, which, however, does not necessarily require a structural connection with one another. If memory 22g and lighting means 13g are structurally separated from one another, a decentralized reading of the contents of the memory 22g is also possible, for example, the light source 13g can be connected to the light 10 and the memory 22g can be connected to the controller 12 separately from this connection process and be read out can.

Both a structurally separate arrangement of memory 22g and lamp 13g and a memory unit 22g and lamp 13g comprehensive unit 39 may allow in one embodiment of the invention, a reading of the memory 22g by a component of the lamp when the bulb 13g is mounted in the lamp or is mounted.

Although Fig. 8 indicates an LED, any other type of lighting means may be provided with a comparable memory 22g. For example, a socket body carrying the luminous means, a type of lamp base or a support structure for the luminous means may be provided with the memory 22g. In the event that the lighting means forms a structural unit together with an operating device for the lighting means, the memory 22g can also be arranged on this structural unit.

The record may be written in the memory 22g when the bulb 13g or the package 39 carrying the bulb 13g is manufactured. The factory-inscription of the data set is therefore preferably at the lamp manufacturer.

Within the framework of the invention, every possible combination of all the features disclosed herein lies with one another, even if they are described in different exemplary embodiments.
