Description

Address assignment for bus-compatible light-emitting device devices, in particular for LEDs

The present invention is in the field of bus-compatible operating devices for light bulbs (ECGs for gas discharge lamps, converters for LEDs, OLEDs ...). In particular, the invention relates to the physical allocation of one or more operating addresses to such an operating device.

In larger rooms and buildings usually a variety of lighting fixtures are available, with individual groups of lighting fixtures, z. B. individual lines an arrangement of ceiling lights, with a control element, eg. B. a simple switch, on or off. In the simplest case, this can be achieved in that, starting from a first operating element, a supply line is laid, to which all lighting fixtures are connected, which are to be actuated by the first operating element. In the same way, the other controls and associated lighting fixtures are wired. However, this approach makes the laying of a variety of supply lines required and has the additional disadvantage that a once selected, hard-wired assignment of lighting fixtures to a control can be changed only with great effort.

This disadvantage is counteracted in principle by the control system described in the European patent application EP 90 100 465 of the same Applicant. According to This prior art control system is provided for each consumer an upstream control receiver. Further, the known control system comprises a commander, with which the controls are in communication, and a control line for the transmission of control commands from the commander to the control receivers and possibly also of control signals in the reverse direction. All control receivers are connected to the commander via a common control line and a supply line, so that the wiring of the control receiver and the associated consumers simplified. However, the assignment of the individual consumers to a superordinate consumer group is carried out by a relatively complicated and complicated programming process. Essentially, the programming process is based on the fact that a production number (originating address) already stored in the control receiver during production, which identifies the specification of the connected consumer, can be identified by an operating address, which is e.g. B. the room number, the group number and the single consumer number can be replaced is replaced.

For commissioning the known control system, therefore, a commissioning program must be set in motion to initialize the consumer, which requires the previous programming by a specialist. As described, the central commander recognizes the configuration of the one connected to the control receiver

Consumer at the from the control receiver to the

Commander transmitted production number

(Source address). If the production number z. B. due to a longer storage of the lighting fixture Between the production and the installation faulty, it inevitably leads to errors in the operation of the control system. In addition to the necessary programming by a specialist, this represents a significant disadvantage of the known control system.

From DE 4327809 a method for driving groups summarized consumers in response to the operation of a provided for each consumer group control is known. During a commissioning phase, the determination of the

Group assignment of consumers the consumers of a first consumer group each with first

Connected to control receivers, - a first group address, which indicates the assignment of the first consumer group to a first operating element, stored in the first control receivers,

the consumers of a second consumer group are each connected to second tax receivers,

- A second group address, which indicates the assignment of the second consumer group to a second control element, stored as a result of actuation of the second control element in the second control receivers, while the stored in the first control receivers first group address is maintained, possibly with existing groups of consumers will be successively treated in the same way until all consumers are connected to associated tax recipients,

- Wherein during an operating phase due to an operation of a particular control element to samtliche control receiver a group address is transmitted, which indicates the operated control element, and the control of a consumer connected to a control receiver only takes place when the stored in the respective control receiver group address matches the transmitted group address.

It is an object of the invention to propose an improved address allocation.

This object is achieved according to the invention by the features of the independent claims. The dependent claims further form the central idea of the invention particularly advantageous.

A first aspect of the invention relates to a method for allocating an address to a bus-enabled operating device for light sources, in particular LEDs. The operating device is connected to a light sensor, which is assigned to the light sources, comprising the steps:

Sending an address assignment command via a bus to at least one operating device to set the operating device in an address allocation mode, sending an address to be assigned over the bus, and allocating the address to be assigned to an operating device whose light sensor detects a changing light incidence.

Thus, this method can also be applied to bulbs that can not be easily taken out of a socket for physical address assignment. In the address allocation mode, the operating device can switch on at least one connected illuminant.

In order to detect the change in light incidence, a reference measurement can be carried out before the light source is switched on and this reference value can be stored.

The address to be assigned can be assigned to an operating device whose light sensor detects an increased incidence of light in the address allocation mode.

The incidence of light can be changed by a reflective surface, for example the hand of a user or an external light source. As a result, the light emitted by the light source is reflected back to the light sensor.

In the address allocation mode, the operating device can independently operate at least two different light sources, in particular LEDs of different spectrum, and the operating unit can be assigned an address specifically for each of the at least two different light sources.

The operating device can drive the various lamps sequentially for address allocation for the operation of the various lamps.

As a light sensor, a photodiode, in particular a reverse-operated LED can be used.

The operating device can operate an RGB (red, green, blue) light emitting diode module. A central processing unit can detect the completed allocation of an address by means of feedback via the bus or via electrical characteristic values, in particular a jump in the current consumption, if the operating device which has completed an address allocation turns on a further illuminant.

Another aspect of the invention relates to an operating device for lamps, in particular LEDs, which is designed to carry out a method of the type described above.

Lighting system, in particular for exterior lighting, with a central control unit, at least one operating device for lighting means, in particular LEDs, which is connected to the control unit via a bus, wherein the illumination system is designed for carrying out a method of the type described above.

Further advantages, characteristics and features of the invention will now be explained with reference to the figures of the accompanying drawings.

Fig. 6 is a flowchart for explaining the inventive method for

Addressing on the part of the central unit.

First, a first exemplary embodiment of an inventive lighting system 9 will be explained with reference to FIG. 1. Several operating devices 3 are connected via one or more bus lines 2. To the one or more bus lines 2, a preferably central control unit 1 is connected. Each operating device 3 controls one or more lighting means 5 or comparable building technology means, preferably one or more LEDs.

However, alternatively or additionally other illuminants, such as, for example, halogen or gas discharge lamps may be provided.

Each operating device 3 is further assigned a light sensor 6. This can be, for example, a reverse-operated LED, which thus serves as a photodiode. A reversely operated LED is particularly advantageous if it serves as a light source in normal operation.

In accordance with the invention, an address is now physically assigned to an operating device by the incidence of light on a light sensor 6 assigned to the operating device

This can be done, for example, by using the light emitted by the lamps themselves (i.e., by reflecting this light in the direction of the light sensor), by an external light source 10, for example a laser pointer, or by shading the light sensor 6.

In the exemplary embodiment of FIG. 1, the light emitted by the luminous means is reflected by a reflecting surface 4, in this case one hand, so that a change in the incidence of light, in particular an increase in the light measurement, results for the light sensor 6.

2 shows a second exemplary embodiment of the operating device, in which this is shown as a multi-channel system 3. In this case, a multi-channel system is understood to mean an operating device which has a plurality of preferably can operate independently of each other with regard to the emission spectrum different light sources.

In the present example, several differently colored LEDs 5 are provided.

The multi-channel system can be covered with a diffusing screen 7 in order to mix the light of the individual LEDs and thus to produce the impression of a mixed light, in particular of a white light, on the viewer.

As a reflector 4 of the emitted light of the first LED 5 is used, for example, a kind of "cat's eye." In this embodiment, each light source has an associated light sensor, alternatively, however, a light sensor could be used for multiple bulbs For m this case, the first light source takes place in such a way that the reflector 4 is held directly over the light sensor associated with the light source.

A third exemplary embodiment is explained in FIG. 3. This is also a

Multi-channel system 3, in which case an RGB light-emitting diode module 8

(or more LEDs of the same color) and an additional one

Light sensor 7 are provided. In the exemplary embodiment is shown how the red light emitting diode 5 acts as a light emitter. The green light-emitting diode 6 serves as a light sensor by reversing, that is operated with a reverse voltage and thus as a photodiode. The operation of this RGB module 8 is explained in more detail in the flowchart of FIG. An example of an addressing method in a multi-lamp operating device is shown in FIG.

In this exemplary embodiment, it is assumed that each luminous means has in each case a corresponding light sensor, for example a further, reversely operated LED. However, it would also be conceivable to have an operating device in which several lamps share a light sensor.

The start of the method is initiated, for example, triggered by a user at a user interface of the central control unit in step SlOl by sending an address assignment command, which sends the control unit in the sense of a "broadcast" on the bus, which puts each connected device in an address allocation mode becomes.

Thereupon, a first operating address to be issued is sent by the control unit.

In step S102, the operation ger turns on the first channel x. The first (or possibly only) light source, which depends on the channel, is thereby also switched on.

On a second channel x + 1 takes the operating device in

Step S103 before a reference measurement, the result is stored in the Betriebsgerat.

In a following step S104, S105 it is detected whether at the second channel x + 1 (light measuring channel) a significantly higher

Light is measured. For this purpose, a light sensor on channel x + 1 m measures the current brightness in step S104. Subsequently, this is compared with the reference value in step S105.

If light emitted by the light source at channel x is reflected by deliberate manipulation of the user, the light incident on the light sensor on channel x + 1 increases.

When measuring such a light value increase leaves the flow. The current bus address to be assigned is placed in S106 on the first channel x and this assignment is stored in a memory of the operating device.

This address assignment of individual channels is repeated until the last channel of an operating device has been assigned an address. For this, the algorithm jumps back to step x at step S107 to step S102 for turning on the illuminant each time. For each jump, x is incremented by 1 so that the next one is prepared for address assignment.

After all channels have been processed, therefore, all bulbs are also turned on. This or the associated channels are turned off again in step S108 before completion.

This shutdown, ie, the load current that suddenly drops due to this and / or a bus pressure message from the operating device, can provide the control unit with the information about how many and which addresses belong to a multi-channel operating device. A concrete application example of the addressing method from FIG. 4 is shown in FIG. 5a and FIG. This is a lighting system with Betπebsgerat, which is equipped with an RGB light emitting diode module and an additional light sensor. This corresponds to the exemplary embodiment in FIG.

After initialization by the control apparatus and after the operation apparatus has been set in an address allocation mode in step S201, a first address A to be issued is sent out by the control unit in step S202.

The red LED is then turned on in step S203. Subsequently, a reference light measurement, which serves as a reference measurement, is carried out on the green, reverse-operated LED in step S204.

Thereafter, a loop of steps S205, S206 runs until a reflector reflects the light emitted from the red LED back to the green LED.

When measuring this increase, the address A is set to the channel of the red LED in step S207.

After the operating device has assigned the address to the channel, it switches on the next LED in step S208, in this case the green LED.

The control unit registers this jump in the power consumption and sends a new address B in step S209. The process repeats itself for the green LED, whereby the red LED still lights up and the blue LED is operated reversely as a light sensor.

As shown in FIG. 5b, the additional light sensor is last used in the blue LED in order to detect the changed incidence of light. However, it is also conceivable that no additional light sensor is used, but one of the existing LEDs, in this case the red or the green, reverse operated operated as such. For this, however, the algorithm had to be adapted insofar that at least one LED is switched off in front of it.

After each of the three channels of the RGB light emitting module has been assigned an address, the three LEDs turn off in step S220.

Alternatively, it is also possible to carry out this addressing method for only a single LED. In this case, because there is no second LED, there must be an external one

Light source 10, for example, a laser pointer can be used. As an external light source 10 but also others

Light sources, especially when they emit a well-directed light. The emitted light can also be in the non-visible area, for example, an infrared remote control can be used. In this way, single-color systems can be addressed, in which no separately controllable LEDs are present.

The external light source (10) can also transmit the address to be assigned directly via a modulation of the emitted light. This light can either be through a additional light sensor or one of the existing LEDs, which is used reverse operated as such, are received. The operating device can read the data from the received modulated light and determine the address based on the data.

An example of the addressing method in the control unit shown in the embodiment in FIG. 1 is shown in FIG.

In this example, the control unit detects a feedback message about the allocation of an address by a change, in particular a jump in the current consumption.

However, it would also be conceivable to record other electrical or other characteristic values or signals, for example the light. However, it would also be possible to directly communicate the operating devices with the central unit via a bus or other means of communication.

After the start of the process in step S301, initialization takes place in step S302 and step S303. In this step, an address assignment command is switched to all the operating devices in step S302. These are put into the address allocation mode. Then, at step S303, the first channel is activated at each operation device.

Alternatively, however, other procedures of initialization can be used, for example, an address allocation command can only be given to a single operating device. This may be previously selected by a random mode or according to a scheme implemented in the control unit. Still must not necessarily only one channel are activated, it can also several, or as shown in Figure 2, all channels are activated.

After the initialization, a first address a is sent out from the control unit in step S304. This state stops in through the loop S304, S305 until a change, in this case a jump in current consumption, is measured in step S305. The current change is triggered by either a channel has been addressed in a Betriebsgerat and then another channel with associated light source has been turned on or that an operating device has completed the addressing of all channels and then turned off all. In the first case, the power consumption change is characterized by a slight increase, in the second case by a clearer decrease. This distinction can be used for additional process steps, which are not shown in Fig. 5.

After the current consumption change detected in step S305, the control unit selects another address a = a + 1 in step S306.

If the total current consumption of all the lighting means is not zero, which means that at least one operating device still has the first channel activated, the process is repeated by jumping back from step S307 to step S304.

In this example, the user can select the next operating device to be addressed himself. However, another approach would be conceivable in which the User is prescribed the next device to be addressed, for example by being selected by a random mode or by a scheme implemented in the control unit.

If, after passing through the algorithm, the total current consumption of all the lighting means in step S307 is equal to zero, this means that all operating devices have completed the addressing. Accordingly, the process is completed in step S308.
