Description
Die vorliegende Erfindung betrifft eine Leuchtenanordnung für ein Fahrzeug mit eher Lichtquelle, einer Lichtscheibe, die in Richtung der Lichtemission der Lichtquelle angeordnet ist, und einem Lichtleiter, der im Bereich der Lichtemission der Lichtquelle angeordnet ist und der in diesem Bereich eine Lichteinkoppelfläche umfasst, auf die von der Lichtquelle emittiertes Licht fälltThe present invention relates to a lighting arrangement for a vehicle with a light source, a light disk, which is arranged in the direction of the light emission of the light source, and a light guide, which is arranged in the region of the light emission of the light source and in this area comprises a light coupling surface, to which light emitted by the light source falls
Bei der Neugestaltung von Fahrzeugen ergibt sich das Problem, dass aus aerodynamischen und gestalterischen Gründen der Bauraum, welcher für Leuchtenanordnungen bereitgestellt wird, sehr begrenzt ist. Dies muss bei der Gestaltung der Leuchten, die im Fahrzeug an der Vorder- und Rückseite sowie in den Seitenbereichen vorgesehen sind, berücksichtigt werden.When redesigning vehicles there is the problem that for aerodynamic and design reasons, the space that is provided for lighting arrangements, is very limited. This must be taken into account when designing the lights that are provided in the vehicle at the front and rear as well as in the side areas.

Es ist die Aufgabe der vorliegenden Erfindung, eine Leuchtenanordnung der Eingangs genannten Art bereitzustellen, durch die verschiedene lichttechnische Funktionen für das Fahrzeug bereitgestellt werden können und die gleichzeitig an sehr begrenzte Bauraumverhältnisse für die Aufnahme der Leuchtenanordnung im Fahrzeug angepasst werden kann.It is the object of the present invention to provide a luminaire arrangement of the type mentioned above, can be provided by the various lighting functions for the vehicle and can be adapted to very limited space conditions for receiving the lamp assembly in the vehicle at the same time.
Diese Aufgabe wird durch eine Leuchtenanordnung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen ergeben sich aus den Unteransprüchen.This object is achieved by a luminaire arrangement with the features of
Die erfindungsgemäße Leuchtenanordnung ist dadurch gekennzeichnet, dass der Lichtleiter Auskoppelflächen umfasst, durch welche Licht bezüglich der Fahrtrichtung des Fahrzeug seitlich abstrahlbar ist. Dabei stellt das von dem Lichtleiter abgestrahlte Licht ein Seitenlicht („sidemarker light” für US-Fahrzeuge) bereit. Durch die Leuchtenanordnung wird das von einer Lichtquelle für eine herkömmliche Lichtfunktion an der Vorderseite oder am Heck des Fahrzeugs für das Seitenlicht ausgenutzt. Dabei ist es nicht erforderlich, eine weitere Lichtquelle für das Seitenlicht vorzusehen. Ferner ist der Bauraum, welcher für das Seitenlicht nötig ist, auf Grund der Verwendung des Lichtleiters sehr gering.The luminaire arrangement according to the invention is characterized in that the optical waveguide comprises decoupling surfaces through which light can be emitted laterally with respect to the direction of travel of the vehicle. The light emitted by the light guide provides a side light ("sidemarker light" for US vehicles). The light assembly exploits that from a light source for a conventional light function at the front or at the rear of the vehicle for the side light. It is not necessary to provide another light source for the side light. Furthermore, the space required for the side light, due to the use of the light guide is very low.
Die Lichtscheibe erstreckt sich erfindungsgemäß im Wesentlichen senkrecht zur Fahrtrichtung. Der Lichtleiter erstreckt sich zumindest abschnittsweise im Wesentlichen parallel zur Fahrtrichtung. Vorzugsweise schließt der Lichtleiter direkt an die Lichtscheibe an und krümmt sich zur Seite des Fahrzeugs. Dabei besitzt der Lichtleiter erfindungsgemäß im Wesentlichen die Form eines Torus.The lens extends according to the invention substantially perpendicular to the direction of travel. The light guide extends at least partially substantially parallel to the direction of travel. Preferably, the light guide directly connects to the lens and curves to the side of the vehicle. In this case, the light guide according to the invention essentially has the shape of a torus.
Das durch die Lichtscheibe durchtretende Licht kann beispielsweise ein Abblendlicht oder ein Schlusslicht bereitstellen. Die erfindungsgemäße Leuchtenanordnung stellt somit eine Kombination eines Abblendlichts mit einem Seitenlicht bzw. eines Schlusslichts mit einem Seitenlicht bereit.The light passing through the lens may provide, for example, a low beam or a tail light. The luminaire arrangement according to the invention thus provides a combination of a low beam with a sidelight or a tail light with a sidelight.
