Title: ILLUMINATION DEVICE
Abstract:
The invention relates to an illumination device, in particular for a motor vehicle, comprising one or more multi-color LED units (3) which each have a settable color point and settable brightness, wherein each multi-color LED unit (3) is an individual semiconductor component having multiple single-color LEDs (301, 302, 303, 304) of different colors and a microcontroller (4), wherein the single-color LEDs (301, 302, 303, 304) and the microcontroller (4) are surrounded by a housing of the semiconductor component. The microcontroller (4) is designed to control each single-color LED (301, 302, 303, 304) of an associated multi-color LED unit (3) depending on a current temperature value of the associated multi-color LED unit (3) 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 (3).
