Illumination device comprising multiple LEDs and a sensitive switch

摘要

The illuminant has an opto-electronic sensor arrangement (3) working according to the reflex light scanner principle, an electronic control unit which controls the emitter (5) heads for and the switching element depending on the output signal of the photo-sensitive element (7). One of the multiple light emitting diodes of the illuminant forms the emitter. The electronic control unit is adjusted to control the emitter for sending the light measuring ray, as well as the light emitting diodes, as illuminant.
