Description

The The present invention is in the field of bus-enabled operating devices for illuminants (ECGs for gas discharge lamps, Converter for LEDs, OLEDs ...). The invention relates in particular the physical allocation of one or more operating addresses to such a control gear.

In larger rooms and buildings are in the Usually a variety of lighting fixtures available, wherein individual groups of these lighting fixtures, z. B. single lines an arrangement of ceiling lights, with a control element, z. B. a simple switch, on or off. In the simplest case, this can be achieved by starting from a first control element a supply line is laid on which connected all lighting fixtures are that are operated with the first control should. In the same way, the other controls and wired respectively associated lighting fixture. These However, the procedure involves laying a variety of utility lines required and has the additional disadvantage that Once selected, hard-wired assignment of lighting fixtures changed to a control only with great effort can be.

This disadvantage is in principle by that in the European patent application EP 90 100 465 encountered by the same applicant. According to this previously known control system, an upstream control receiver is provided for each consumer. Furthermore, 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 the control receivers are connected to the commander via a common control line and a supply line, so that simplifies the wiring of the control receiver and the associated consumers. However, the assignment of the individual consumers to a superordinate consumer group is done 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, is 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.

to Commissioning of the known control system must therefore for initialization the consumer set a commissioning program in motion, which requires the previous programming by a specialist. As described, the central controller recognizes the configuration of the to the consumer connected to the tax receiver the transmitted from the tax receiver to the commander Production number (source address). Is the production number z. B. due to a longer storage of the lighting between The production and installation faulty, it comes inevitably to errors in the operation of the tax system. This puts in addition to the necessary Programming by a specialist is a major disadvantage the known control system.

From the DE 4327809 is a method for controlling groups summarized consumers in response to the operation of a provided for each consumer group control known. In this case, during a commissioning phase for determining the group assignment of the consumers, the consumers of a first consumer group are each connected to first control receivers,

• A first group address, which indicates the assignment of the first consumer group to a first operating element, is stored in the first control receiver,
• 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 operating element, stored as a result of actuation of the second operating 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 receivers,
• - Wherein a group address is transmitted during an operating phase due to an operation of a specific control element to all the control receiver, which indicates the operated control, and the control of a consumer connected to a control receiver only takes place when stored in the respective control receiver group address matches the transmitted group address.

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

These The object is achieved by the features of the independent Claims solved. The dependent claims form the central idea of the invention particularly advantageous further.

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

• Sending an address assignment command via a bus to at least one operating device in order to place the operating device in an address allocation mode,
• - sending an address to be given over the bus, and
• - Allocation of the address to be given to a control gear whose light sensor detects a changing light incidence.

Consequently This method can also be applied to bulbs, the not readily available for physical address assignment from a version can be taken out.

to Detection of light incidence change can be done before switching on the illuminant is a reference measurement performed and this reference value are stored.

The to be given address can be assigned to a control gear whose light sensor is increased in the address allocation mode Light incident detected.

Of the Light can be transmitted through a reflective surface, eg. changed the hand of a user or an external light source become. As a result, namely emitted by the light source Light amplifies reflected back to the light sensor.

in the Address allocation mode, the operating device can be independent each other at least two different bulbs, in particular LEDs of different spectrum, operate and the operating device specific to each of the least two different bulbs be assigned an address.

The Operating device can be used for address allocation for the Operation of different bulbs the different bulbs drive sequentially.

When Light sensor may be a photodiode, in particular a reverse operated LED to be used.

The Operating device can be a RGB (red, green, blue) light-emitting diode module operate.

A Central unit can complete the assignment of an address Feedback via the bus or via electrical Characteristics, in particular detect a jump in the current consumption, if the operating device, which completed an address allocation has switched on another light source.

6 a flowchart for explaining the method according to the invention for addressing tion on the part of the central unit.

First, a first embodiment of a lighting system according to the invention 9 based on 1 be explained. Several operating devices 3 are over one or more bus lines 2 connected. To the one or more bus lines 2 is a preferably central control unit 1 connected. Each operating device 3 controls one or more bulbs 5 or comparable building services equipment, preferably one or more LEDs.

It however, may alternatively or additionally other bulbs, such as, for example, halogen or gas discharge lamps be provided.

Each operating device 3 is still a light sensor 6 assigned. 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.

According to the invention, an address is now physically allocated to an operating device by the incidence of light on a light sensor assigned to the operating device 6 "Manipulated" is. This can, for example, by using the light emitted by the lamps themselves (ie, by reflection of 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 respectively.

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

2 shows a second embodiment of the operating device in which this as a multi-channel system 3 will be shown. In this case, a multi-channel system is understood to be an operating device which can operate a plurality of light-emitting means, which are preferably different with respect to the emission spectrum, independently of one another.

In the present example are several differently colored LEDs 5 intended.

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

As a reflector 4 the emitted light of the first LED 5 serves, for example, a kind of "cat's eye". In this embodiment, each illuminant has an associated light sensor; Alternatively, however, a light sensor could also be used for several lamps. Furthermore, all bulbs are turned on here, an address assignment to the first light source in this case takes place in such a way that the reflector 4 is held directly above the light source associated with the light sensor.

A third embodiment is in 3 explained. This is also a multi-channel system 3 , where here is an RGB light emitting diode module 8th (or multiple LEDs of the same color) and an additional light sensor 7 are provided. In the embodiment, it is shown how the red light emitting diode 5 acts as a light emitter. The green LED 6 serves as a light sensor by reversing, ie operated with a reverse voltage and thus as a photodiode. The operation of this RGB module 8th is shown in the flow chart of 5 explained in more detail.

An example of an addressing method in a multi-lamp operating device is described in US Pat 4 shown.

In This embodiment assumes that each light source in each case a corresponding light sensor, for example another, reverse operated LED has. However, it would be conceivable also a control gear, in which there are several bulbs share a light sensor.

Of the Start of the process is, for example, triggered by a User at a user interface of the central control unit, initiated in step S101 by sending an address assignment command, the control unit in the sense of a "broadcast" over sends the bus, causing each connected operating device is placed in an address allocation mode.

Thereon there will be a first operating address to be given by the control unit sent.

in the Step S102, the operating device switches the first channel x. The first (or possibly only) light source attached to the channel Hangs, is also turned on. At a second Channel x + 1, the operating device takes in step S103 one Reference measurement before, the result in the operating device is stored.

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

To do this, a light sensor measures at channel x + 1 In step S104, the current brightness is subsequently compared with the reference value in step S105.

Becomes now light emitted by the light source at channel x through conscious Manipulation of the user reflects that increases on the light sensor on channel x + 1 incident light.

at Measurement of such a light value increase leaves the process. The current bus address to be assigned is in S106 on the first Channel x is laid and this assignment is in a memory of the operating device stored.

This Address assignment of individual channels is repeated in this way often until the last channel of an operating device has an address has been assigned. For this the algorithm jumps every time at step S107 to step S102 for turning on the lighting means back to channel x. At each return, x incremented by 1, leaving the next to address assignment is prepared.

After this all channels have been processed, too all bulbs switched on. This or the associated Channels are turned off again in step S108 before completion.

This Switch off, d. H. the resulting load capacity and / or a bus feedback from the operating device can provide the control unit with information on how many and which addresses belong to a multi-channel operating device.

A concrete application example of the addressing method 4 is in 5a and 5b shown. This is a lighting system with operating device, which is equipped with an RGB light-emitting diode module and an additional light sensor. This corresponds to the embodiment in 3 ,

To initialization by the controller and after that Operating apparatus in step S201 in an address allocation mode has been offset, a first one to be issued is set in step S202 Address A is sent from the control unit.

The Red LED is then turned on in step S203. At the green, reverse operated LED is subsequently a reference light measurement in step S204 made, which serves as a reference measurement.

thereupon a loop goes through steps S205, S206 until a reflector illuminates the light emitted by the red LED the green LED reflected back.

at Measurement of this increase becomes address A at step S207 Channel laid by the red LED.

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

The Control unit registers this jump in the power consumption and sends out a new address B in step S209.

Of the Process repeats itself for the green LED, where the red LED is still lit and the blue LED is reversed operated as a light sensor.

As 5b shows, the blue LED last the additional light sensor is used to detect the change in 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, revers operated operated as such. For this, however, the algorithm would have to be adjusted so that at least one LED is switched off before.

After this each of the three channels of the RGB light emitting diode module has an address has been assigned, the three LEDs turn on in step S220 out again.

Alternatively, it is also possible to perform this addressing method for only a single LED. In this case, because there is no second LED, there must be an external light source 10 , For example, a laser pointer can be used. As an external light source 10 But other sources of light can be used, especially if 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 be received either by an additional light sensor or one of the existing LEDs, which is used reversely operated as such. 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, which in the embodiment in 1 is shown in 6 played.

In This example is from the control unit via a feedback the allocation of an address by a change, in particular detected a jump in the current consumption.

Conceivable But would also be a collection of other electrical or other characteristics or signals, such as light. Possible But would also be an immediate communication of the operating devices with the central unit via a bus or other means of communication.

To the start of the process in step S301 takes place in step S302 and step S303, an initialization takes place. This will be in Step S302, an address assignment command to all the operating devices connected. These are put into the address allocation mode. Subsequently, in step S303, in each operating device, the first channel activated.

Alternatively, however, other procedures of initialization can be used, for example, an address assignment 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. Furthermore, not necessarily only one channel must be activated, it can also several, or as in 2 shown, all channels are activated.

After the initialization, a first address a is sent out from the control unit in step S304. This state continues through loop S304, S305 until a change, in this case a jump in current draw, is measured in step S305. The change in current is triggered by the fact that either one channel has been addressed in an operating device 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 switched off all. In the first case, the change in power consumption is characterized by a slight increase, in the second case by a clearer decrease. This distinction can be used for additional process steps that are described in 5 not shown.

To the current consumption change detected in step S305 At step S306, the control unit becomes another address a = a + 1 selected.

If the total power consumption of all bulbs is not zero, which is means that at least one operating device still the first Channel is activated, the procedure is repeated by step S307 is returned to step S304.

In In this example, the user may be the next to be addressed Select operating device yourself. It would be possible but also a different way in which the user the next to be addressed control gear prescribed For example, by this by a random mode or selected according to a scheme implemented in the control unit becomes.

If after passing through the algorithm the total power consumption of all Illuminant is zero in step S307, it means that all operating devices have completed the addressing. Accordingly the process is completed in step S308.
