Abstract

A lighting arrangement with a control unit and two LED lighting modules, each comprising an LED matrix. Control information, including an image signal for generating a light image, can be generated with the control unit for each lighting module, and the light image can be generated with the LED matrix of each lighting module, which the control unit has generated for this lighting module. The control unit is connected to the lighting modules for the transmission of the image signals. The first lighting module has a processing unit and a first interface via which the information for the lighting modules can be extracted from the signal generated by the control unit. The processing unit provides the information intended for the second lighting module at the first interface of the first lighting module, and wherein the second lighting module is connected to the first interface of the first lighting module.

First claim

What is claimed is:

1. A lighting arrangement comprising:
a control unit; and
first and second LED lighting modules, each comprising an LED matrix,
wherein information is generated by the control unit, the information including at least control information and an image signal for each of the first and second lighting modules to generate a light image,
wherein the light image is generated by each of the first and second lighting modules, respectively, with the LED matrix of each of the first and second lighting modules,
wherein the control unit is connected to the first lighting module for the transmission of the information to the first and second lighting modules,
wherein the first lighting module has a processing unit and a first interface, and via the processing unit of the first lighting module, the control information and the image signal for each of the first and second lighting modules is extracted from the information generated by and transmitted to the first lighting module from the control unit,
wherein the second lighting module is connected to the first interface of the first lighting module,
wherein the processing unit of the first lighting module provides the control information and the image signal that is pertinent to the second lighting module to the second lighting module via the first interface of the first lighting module,
wherein the lighting arrangement has at least one peripheral module or actuator for adjusting a focal length, an aperture, or an angular position of one of the first or second lighting modules,
wherein the at least one peripheral module or actuator is assigned to the one of the first or second lighting modules, and
wherein the at least one peripheral module or actuator is connected to the first interface of the first lighting module, to a second interface of the first lighting module or to a third interface of the first lighting module and the processing unit of the first lighting module extracts information for controlling the at least one peripheral module or actuator from the information generated by and transmitted to the first lighting module from the control unit and provides the information for controlling the at least one peripheral module or actuator to the at least one peripheral module or actuator via the first, second or third interface of the first lighting module.

2. The lighting arrangement according to claim 1 , wherein the lighting arrangement has a power supply unit for supplying the first lighting module and the second lighting module with electric current.

3. The lighting arrangement according to claim 2 , wherein the power supply unit is connected to the first interface of the first lighting module or to a second interface of the first lighting module and the processing unit of the first lighting module extracts information for controlling the power supply unit from the information generated by and transmitted to the first lighting module from the control unit and provides the information for controlling the power supply unit to the power supply unit via the first or second interface of the first lighting module.

4. The lighting arrangement according to claim 1 , wherein the connection between the control unit and the first lighting module is a GMSL connection or an Ethernet connection.

5. The lighting arrangement according to claim 1 , wherein the first interface is an RGB video interface.

6. The lighting arrangement according to claim 1 , wherein the second interface is a CAN/UART interface.

7. The lighting arrangement according to claim 1 , wherein the third interface is an SPI interface.

8. The lighting arrangement according to claim 1 , wherein the second interface is a CAN/UART interface.
