Abstract
(EN)

The invention relates to a lighting system (1) for vehicles and to a method for operating a lighting system of this type. The inventive system (1) has a mirror surface (13) made up of a plurality of electronically controllable micromirrors (130-134) which can be switched between two mirror positions. Said mirror surface (13) is lit by a light source (11). The distribution (17) of the light leaving the light outlet opening (16) can be modified to suit almost any requirement by switching a part of the micromirrors (130-134). The system can therefore provide full-beam lights, low-beam lights, fog-lights, etc. using just one light source.
