Abstract
(DE)
Die Erfindung betrifft eine Beleuchtungseinrichtung (1) für ein Fahrzeug sowie ein Betriebsverfahren für eine derartige Beleuchtungseinrichtung. Die erfindungsgemäße Beleuchtungseinrichtung (1) besitzt eine aus einer Vielzahl elektronisch ansteuerbarer und zwischen zwei Spielgeleinstellungen umschaltbarer Mikrospiegel (130-134) aufgebaute Spiegelfläche (13), die von einer Lichtquelle (11) beleuchtet wird. Durch Umschalten eines Teils der Mikrospiegel (130-134) kann die Lichtverteilung (17) des die Lichtaustrittsöffnung (16) verlassenden Lichtes nahezu beliebig variiert werden. Insbesondere können auf diese Weise so unterschiedliche Beleuchtungsfunktionen wie Fernlicht, Abblendlicht, Nebellicht etc. mit nur einer Lichtquelle (11) realisiert werden.
(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.
(FR)
L'invention concerne un système d'éclairage (1) pour véhicule, ainsi qu'un procédé d'exploitation d'un système d'éclairage de ce type. Ce système d'éclairage (1) comprend une surface spéculaire (13) composée d'une pluralité de micromiroirs (130 à 134) à commande électronique et commutables entre deux positionnements spéculaires. La surface spéculaire est éclairée par une source lumineuse (11). Le fait de commuter une partie des micromiroirs (130 à 134) permet de moduler pratiquement à volonté la répartition (17) de la lumière sortant de l'orifice de sortie de la lumière (16). Ce système permet de mettre en oeuvre des fonctions d'éclairage aussi différentes que les phares, les feux de croisement, les feux antibrouillards, etc. avec une seule source lumineuse (11).
