Bauteile einspart und der Montageaufwand reduziert wird.Further intended a motor vehicle with such license plate lighting to be provided. The production costs should be reduced be, by z. B. saves components and reduces assembly costs becomes.
Diese Aufgabe wird erfindungsgemäß durch eine Kennzeichenbeleuchtung mit den Merkmalen des Anspruchs 1 und ein Kraftfahrzeug mit den Merkmalen des Anspruchs 9 gelöst. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.These The object is achieved by a license plate illumination with the features of claim 1 and a motor vehicle with the Characteristics of claim 9 solved. Further advantageous embodiments and further developments emerge from the dependent claims.
Die erfindungsgemäße Kennzeichenbeleuchtung ist gekennzeichnet durch einen Lichtbaustein mit zumindest einer Lichteinkoppelfläche und zumindest zwei Lichtauskoppelflächen sowie durch mindestens eine erste und mindestens eine zweite Lichtquelle. Die Lichtemission der ersten Lichtquelle wird in die zumindest eine Lichteinkoppelfläche eingekoppelt und über die erste Lichtauskoppelfläche so ausgekoppelt, dass das Kennzeichen beleuchtet wird. Die Lichtemission der zweiten Lichtquelle wird in die zumindest eine Lichteinkoppelfläche eingekoppelt und über die zweite Lichtauskoppelfläche so ausgekoppelt, dass Licht für einen Rückfahrscheinwerfer nach hinten emittiert wird.The License plate lighting according to the invention is marked by a light component with at least one light input surface and at least two light output surfaces and by at least a first and at least one second light source. The light emission the first light source is in the at least one light input surface coupled and via the first light output surface so decoupled that the license plate is illuminated. The light emission the second light source is in the at least one light input surface coupled and via the second light output surface so decoupled that light for a reversing light after emitted at the rear.
Gemäß einer bevorzugten Weiterbildung weist der Lichtbaustein eine erste Lichteinkoppelfläche für die erste Lichtquelle und eine zweite Lichteinkoppelfläche für die zweite Lichtquelle auf.According to one preferred development, the light module has a first Lichteinkoppelfläche for the first light source and a second light input surface for the second light source on.
Unter einem Lichtbaustein im Sinne der vorliegenden Erfindung wird ein transparentes, Licht leitendes Element mit mindestens einer Lichteinkoppelfläche und mindestens einer Lichtauskoppelfläche verstanden. Bei der erfindungsgemäße Kennzeichenbeleuchtung hat der Lichtbaustein eine, bevorzugt zwei Lichteinkoppelflächen und zwei Lichtauskoppelflächen. Der Lichtbaustein kann z. B. aus Glas oder einem Kunststoff, insbesondere Polymethylmethacrylat (PMMA) bestehen.Under a light module in the context of the present invention is a transparent, light-conducting element with at least one light input surface and understood at least one light output surface. at the license plate lighting according to the invention has the light module one, preferably two Lichteinkoppelflächen and two light output surfaces. The light brick can z. Example of glass or a plastic, in particular polymethylmethacrylate (PMMA).
Gemäß einer bevorzugten Ausbildung der erfindungsgemäßen Kennzeichenbeleuchtung ist die Lichteinkoppelfläche für die erste Lichtquelle nicht parallel zur ersten Lichtauskoppelfläche. Gleichermaßen kann die Lichteinkoppelfläche für die zweite Lichtquelle nicht parallel zur zweiten Lichtauskoppelfläche sein. Des Weiteren kann die Richtung der Lichtemission der ersten Lichtquelle in dem Lichtbaustein so verändert werden, dass die Richtung des bei der ersten Lichtauskoppelfläche ausgekoppelten Lichts nicht parallel zu der Richtung der Lichtemission der ersten Lichtquelle ist. Gleichermaßen kann die Richtung der Lichtemission der zweiten Lichtquelle in dem Lichtbaustein so verändert werden, dass die Richtung des bei der zweiten Lichtauskoppelfläche ausgekoppelten Lichts nicht parallel zu der Richtung der Lichtemission der zweiten Lichtquelle ist. Der Lichtbaustein verändert somit die Richtung des von den Lichtquellen emittierten Lichts. Dies hat den Vorteil, dass die Lichtquellen nicht gegenüberliegend zu den Lichtauskoppelflächen angeordnet sein müssen, sondern die lichtleitende Wirkung des Lichtbausteins ausgenutzt wird, um die Lichtquellen dort anzuordnen, wo Bauraum für die Lichtquellen zur Verfügung steht.According to one preferred embodiment of the license plate lighting according to the invention is the light input surface for the first light source not parallel to the first light output surface. equally can the light input surface for the second light source not be parallel to the second light output surface. Of Further, the direction of the light emission of the first light source in the light brick are changed so that the direction of the decoupled at the first light output surface light not parallel to the direction of light emission of the first light source is. Similarly, the direction of the light emission of the second light source in the light brick are changed so that the direction of the decoupled at the second light output surface Light not parallel to the direction of light emission of the second Light source is. The light module thus changes the Direction of the light emitted by the light sources. This has the Advantage that the light sources are not opposite to the Lichtauskoppelflächen must be arranged, but the light-guiding effect of the light module is exploited to to arrange the light sources where space for the light sources is available.
Falls es für die Veränderung der Richtung der Lichtemission der ersten und/oder zweiten Lichtquelle erforderlich ist, kann der Brechungsindex des Materials des Lichtbausteins auch variabel sein. D. h. der Lichtbaustein weist in diesem Fall einen inhomogenen Brechungsindex auf.If it for changing the direction of the light emission the first and / or second light source is required, the Refractive index of the material of the light module also be variable. Ie. the light module has in this case an inhomogeneous refractive index on.
Die zweite Lichtquelle ist mit einem Steuergerät verbunden, welches bei der erfindungsgemäßen Kennzeichenbeleuchtung die zweite Lichtquelle zur Bereitstellung der Lichtfunktion eines Rückfahrscheinwerfers ansteuert. Dasselbe oder ein separates Steuergerät kann mit der ersten Lichtquelle verbunden sein und diese zur Bereitstellung der Lichtfunktion der Kennzeichenbeleuchtung ansteuern. Dabei wird die zweite Lichtquelle von dem Steuergerät insbesondere unabhängig von der Ansteuerung der ersten Lichtquelle angesteuert.The second light source is connected to a control unit, which in the license plate lighting according to the invention the second light source for providing the light function of a Reversing lights drives.
