Abstract

An illumination device for a motor vehicle includes one or more multi-color LED units which each have a settable color point and settable brightness, wherein each multi-color LED unit is an individual semiconductor component having multiple single-color LEDs of different colors and a microcontroller. The single-color LEDs and the microcontroller are surrounded by a housing of the semiconductor component. The microcontroller is designed to control each single-color LED of an associated multi-color LED unit depending on a current temperature value of the associated multi-color LED unit in such a way that a set color point and a set brightness are held constant during operation of the associated multi-color LED unit.
