Abstract

The invention relates to an illumination device comprising at least one light (23) provided with at least one LED (22a to 22d), and a microcontroller (10). The microcontroller (10) is designed to vary the colour of the light emitted by the at least one light (3) in a correspondingly controlled manner. The illumination device also comprises at least one temperature sensor (14) coupled to the microcontroller (10), and the microcontroller (10) is also designed to vary the colour of the light emitted by the at least one light (20) according to the temperature measured by the temperature sensor (14). The invention furthermore relates to a cooling device comprising at least one such illumination device.
