Description
Die Erfindung geht aus von einer Beleuchtungseinrichtung eines Fahrzeugs mit wenigstens einer Lichtquelle für eine Beleuchtungsfunktion, von der Licht ausgesandt wird, das in einer Lichtaustrittsrichtung aus der Beleuchtungseinrichtung zur Erzeugung der Beleuchtungsfunktion austritt. In der Beleuchtungseinrichtung ist wenigstens ein Lichtleitelement vorgesehen, das quer zur Lichtaustrittsrichtung verläuft. Von der Lichtquelle ausgesandtes Licht wird in das Lichtleitelement eingekoppelt und aus diesem über seine Längserstreckung verteilt in Lichtaustrittsrichtung ausgekoppelt.The The invention is based on a lighting device of a vehicle with at least one light source for a lighting function, is emitted by the light, in a light exit direction from the illumination device for generating the illumination function exit. In the lighting device is at least one light guide provided, which extends transversely to the light exit direction. From the light source emitted light is in the light guide coupled in and out of this its longitudinal extent distributed in the direction of light exit coupled.

Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Beleuchtungseinrichtung mit den Merkmalen gemäß Anspruch 1 hat demgegenüber den Vorteil, dass mit dem Lichtleitelement eine große, langgestreckte Lichtaustrittsfläche erreicht ist, ohne dass der Bauraum, insbesondere die Bautiefe, der Beleuchtungseinrichtung wesentlich vergrößert ist. Darüber hinaus kann über den Reflektor von der Lichtquelle ausgesandtes Licht mit hohem Wirkungsgrad in das Lichtleitelement eingekoppelt werden.The Lighting device according to the invention with the features according to claim 1 has in contrast the advantage that with the light guide a large, elongated Light-emitting surface is achieved without the space, in particular the depth, the lighting device is substantially increased. Furthermore can over the reflector from the light source emitted light with high efficiency be coupled into the light guide.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Beleuchtungseinrichtung angegeben. Durch die Ausbildung gemäss Anspruch 2 kann der Wirkungsgrad, mit dem von der Lichtquelle ausgesandtes Licht in das Lichtleitelement eingekoppelt wird, nochmals erhöht werden.In the dependent claims are advantageous embodiments and further developments of the illumination device according to the invention specified. Due to the design according to claim 2, the efficiency, with the light emitted by the light source in the light guide is coupled, again increased become.
