Abstract

An illumination arrangement is provided with a control unit, an illumination module including an LED matrix for the generation of light, and a peripheral module connected to the illumination module. The control unit generates data for controlling the illumination module and for controlling the peripheral module. The data for controlling the illumination module and for controlling the peripheral module is transferred to the illumination module. The data for controlling the peripheral module is transferred to the peripheral module. An RGB signal is generated by the control unit for generating a light pattern by the illumination module, and is transferred to the illumination module. The image data of the RGB signal is the data for controlling the illumination module or at least forms a part of the data for controlling the illumination module, and the RGB signal has a range not used for image data.

First claim

The invention claimed is:

1 . An illumination arrangement comprising:
a control unit; an illumination module connected to the control unit via a bidirectional first channel, wherein the illumination module includes an LED matrix for generating light; and a peripheral module connected to the illumination module via a second channel; wherein the control unit generates data for controlling the illumination module and data for controlling the peripheral module, wherein the data for controlling the illumination module and the data for controlling the peripheral module are transferred to the illumination module via the first channel, wherein the data for controlling the peripheral module is transferred to the peripheral module via the second channel, wherein the control unit generates an RGB signal for generating a light pattern by the illumination module, and transfers the RGB signal to the illumination module via the first channel, wherein image data of the RGB signal is the data for controlling the illumination module or forms a part of the data for controlling the illumination module, and wherein the RGB signal has a range that is not used for image data, wherein the data for controlling the peripheral module is included in the range of the RGB signal that is not used for image data.

2 . The illumination arrangement in accordance with claim 1 , wherein the RGB signal has a range which is a blanking range that contains further data for controlling the illumination module.

3 . The illumination arrangement in accordance with claim 1 , wherein the second channel is a bidirectional channel via which data is transferred from the peripheral module to the illumination module and, after being received by the illumination module, is transferred to the control unit via the first channel.

4 . The illumination arrangement in accordance with claim 1 , further including a headlamp, wherein the illumination module and the peripheral module are modules of the headlamp.

5 . The illumination arrangement in accordance with claim 4 , wherein the peripheral module includes electromechanical actors, by which lighting technology properties of the illumination module are manipulated or are performed via a drive of mechanical components of the headlamp.

6 . The illumination arrangement in accordance with claim 5 , wherein the drive is a stepper motor for swiveling the illumination module or a cover for shading the light generated by the illumination module.

7 . The illumination arrangement in accordance with claim 1 , wherein the peripheral module is a light matrix manager or an IC for controlling light functions.

8 . The illumination arrangement in accordance with claim 1 , wherein the data transferred from the peripheral module to the illumination module is diagnostic data that shows the state of the peripheral module.

9 . The illumination arrangement in accordance with claim 1 , wherein the first channel is conducted via a UART connection, SPI connection, a I2C connection, or a GMSL connection.
