Embodiment Construction
[0025] An embodiment of the invention will be described below with the aid of a lighting system in a motor vehicle, which has a plurality of LED units as a lighting unit. Preferably, the lighting device is an ambient interior lighting device. The LED unit is in figure 1 LE1, LE2, . . . , LE26 are plotted in the schematic illustration of . In other words, the lighting device includes 26 LED units. These LED units are connected to the control unit or control device 1 via a communication bus 2 in the form of a LIN bus. By using the LIN bus, technically no more than 26 lighting units can be operated in the lighting device. In the embodiment described here, the LED unit is an RGB LED unit which contains red, green and blue LEDs and which can produce different colors by corresponding color mixing of these LEDs. Furthermore, the brightness of the LEDs and thus the total brightness of the RGB-LED unit can vary.
[0026] LED units LE1 to LE26 via message ME (see figure 2 ) are m...
