The invention relates to a lighting control system with at least two lamps, each of an operating device for locking to change a respective illumination level of the at least two lamps, an input coupled to the respective operating device by means of a communication link Steuerge ¬ advises, and with at least two sensors, each of said at least two lamps is assigned at least one sensor. Each operating unit is adapted to change the respective illumination intensity of the at least two lights, if the respective operating device is addressed by means of a standardized data protocol from the Steuerge ¬ advises. The at least two sensors are adapted to generate a signal that is adjustable in response to which the respective illumination intensity of said at least two lamps. Both the respective operating device and the at least two sensors are adapted to each generate a standardized address, which is determined by the control unit.

State of the art

A generic light control system which according to the so-called standard DALI (Digital Addressable Lighting Interface, digital addressable lighting interface of ¬ le) works, is known. Here, calls for the tax laws advises the at least two sensors and the operation device by means of a DALI command broadcast (Broadcast method) on, to generate a corresponding to the DALI standard, of standardized ¬ th address. By means of a search algorithm can then be present in the light ¬ control system standardized addresses, WEL che were generated from the sensors and operating devices found by the control unit.

A disadvantage of such a lighting control system, the fact is to be considered that a number is limited to within ei ¬ nes lighting control system addressed by the control unit operators, and therefore sensors and operating devices on sixty-four participants together. If the lighting control system and so a relatively large number of sensors, then to obtain the maximum number of addressable operating devices reduced.

Summary of the Invention

The object of the present invention is therefore to provide a lighting control system of the aforementioned type, in which a maximum number on the previous hi ¬ nausgehende number of participants by the control device is responsive.

This object is achieved by a lighting control system having the features of patent claim 1 and by a method of operating a lighting control system having the features of patent claim 13.

Advantageous developments with convenient continuing fertilize the invention are specified in the respective dependent claims. The generic light control system according to the invention then further formed a way that the sensor detects the standardized address comprising adapted to a proprietary data protocol of the control unit to be processed th, wherein the respective operating device is designed to ignore the proprietary data protocol. By using different data protocols to the respective response of the sensors and the operating devices, the maximum number of standardized addresses having participants can be increased in the light control system. The lighting control system is largely standardized ¬ Siert, as participants standardized addresses aufwei ¬ sen. Simultaneously, the light control system is particularly convenient and low fuel consumption can be controlled, since a particularly high number of sensors can be used without using the sensors due to the number of standard according maximum usable operating devices is reduced. The lighting control system is particularly flexible expandable addition, as additional participants are integrated into the lighting control system retrofitted easily.

In an advantageous embodiment of the invention, the sensor is associated with one, in particular visual and / or akusti ¬ SChE signaling device by means wel ¬ cher a spoken to the standardized ad ress having the sensor is signaled. The Senso ¬ ren are thus adapted to an operator to communicate their spatial arrangement or the respective mounting location. For locating the addressed sensors these are prompted by the control unit to make itself by an optical and / or acoustic signal. The optical and / or acoustic signal off Bende sensor is therefore wanted by the operator to determine a spatial arrangement of the sensors.

In a further advantageous embodiment of the invention, the at least two sensors are adapted to the standardized address, which is determined by the control unit to generate a random address. When generating random addresses, especially at random addresses that are 24 bits long according to the DALI standard, is particularly safe ensured that each sensor egg ne unique address generated.

Advantageously, the controller is to be ¬ sets, allocate the standardized address sensor having a standardized operating address. As Be ¬ can drive addresses, especially if the Lichtsteuer- system operates according to the DALI standard, short addresses to be shared ¬ which enable a particularly rapid response of the sensors. After the DALI standard short addresses are 6 bits long. Moreover, a sensor, wherein the standardized operating address has been allocated, are combined with one or more subscribers to a group.

Furthermore, it has been found to be advantageous if the at least two sensors are adapted to receive a Adressiertsein to communicate. For example, the sensor can communicate that it has already delivered an address ¬ reported and under the ongoing commissioning of the lighting control system re-addressing is not possible. Alternatively, a question may be communicated by means of the sensor whether a re-addressing of the sensor with a new address is desired. The lighting control system is particularly flexible in that a further sensor is also subsequently be easily integrated into the lighting control system.

In an advantageous embodiment of the invention the control unit is adapted to store a the sensor face assignable, in particular graphical and / or textual Raumin ¬ formation. After locating the addressed sensor by the operator, the operator can thus the spatial information which gungsort over the Anbrin- is the sensor information, entered in the control unit. The graphical space information may in this case comprise a map, textual spatial information a textual description of the mounting location of the sensor. As a result, allows the control unit to Anbrin- gungsort of the sensor, the location of the signal generation, the standardized address of the sensor, in particular, assigns to its standardized operating address.

In a further advantageous manner comprises Lichtsteuersys ¬ tem a particular graphic, Benutzungsschnittstel- Ie, which is adapted to receive a sensor and / or the light attributable to communicate information. This allows a functionality of the lighting control system simply illustrated, in particular visualized who ¬. For example, may be communicated, which currently sen sors generate a signal and / or as a strong signal from the sensor is generated. Similarly, a current release of the illuminance of the light can be communi cates ¬.

It is advantageous furthermore, if the and / or the light identifiable information summarizes the sensor a particular graphical and / or textual, spatial information environmentally. Thereby, the mounting location of the sensor and / or the lamp to a user of Lichtsteuersys ¬ tems, such as the operator, to communicate.

Advantageously, the at least two sensors are connected in parallel. This one installation cost to install the sensors is particularly low and there are a variety of topologies allows the mounting of the sensors. Furthermore, as particularly easy to add the lighting control system subsequently more sensors. In addition, for the light control system a control unit is used, which has only one input for the connection of sensors while still providing a discrimination of the single addressed sensor is made possible.

In a further advantageous embodiment of the invention, the at least two sensors comprise an optical sensor and / or a presence sensor. The presence sensor can be configured as a passive sensor which detects as an infrared radiation of the environment and / or as an active sensor, which can transmit ultrasound and / or electromagnetic waves and received. Likewise, a plurality of sensor functions can be formed integrally in a single sensor.

The sensors enable adjustment of constant light levels in an illuminated by the lamp chamber as a function about the incidence of daylight in the room. Furthermore, allows for particularly efficient operations of the lighting control system when the lamp is then operated le ¬ diglich when about the presence sensor reports a presence of a person in the room. Furthermore, it has shown to be advantageous when the associated one light sensor is formed in the lamp in ¬ tegriert. Thus, the sensor in a particularly simple manner can be mitverkabelt with the wiring of the luminaire.

Provided that the light control system, which operates an individual control of operating devices of the lamps, such as electronic ballasts, made possible by means of the control unit according to the DALI standard can, a five-core cables are used instead of egg ¬ nes conventional three-core cable for wiring of the lamps. In this case, it is advisable to use the two free wires for DALI and to connect the sensors as the devices of the lamps on the DALI line.

Finally, the light control system may be integrated into a building management system, in which the at least two sensors include a temperature sensor and / or an air humidity sensor and / or an air quality sensor. When integrating the lighting control system in the building management system mitverkabelte temperature sensors, humidity sensors and / or air quality sensors can be used for economical and efficient operation of the building management system with the optical sensors and / or presence sensors. Here, for example, from the temperature sensors, humidity sensors ¬ and / or air quality sensors supplied information about operation of the air conditioning equipment used. The generation of the addresses of Temperatursenso ¬ reindeer, humidity sensors and / or air quality sensors, allocating operational addresses as well as the response of these sensors by means of the control unit is in this case analogous to that described for the optical sensors and / or presence sensors methods.

The control system for the inventive light beschrie ¬ surrounded preferred embodiments and advantages also apply for the method of operating a lighting control system.
