Embodiment Construction

[0025] The lighting device according to the invention can be used in a vehicle, preferably in a motor vehicle, in the front and / or rear area of ​​the vehicle.

[0026] exist figure 1 and 2 shows a rear lighting system comprising a housing 1 into which a flashlight or reversing light light source is integrated in the upper region 2 . In the middle area 3 connected to the upper area 2 and in the lower area 4, a rear light illuminant 5 is arranged, which has a plurality of LED light sources 6 arranged on a common printed circuit board and areal light sources. waveguide7. The strip-shaped LED light source 6 is arranged in the central region 3 of the housing 1 and couples light in on the narrow side of the light guide 7 . On the side facing the bottom 8 of the housing 1, the optical waveguide 7 has an outcoupling element (not shown), so that the coupled-in light is located at the bottom of the optical waveguide 7 facing away from the housing 1 in order to generate the rear light...

Abstract

The invention relates to a lighting device for a vehicle, comprising a laser light source (11) and a light-guiding device in front of the laser light source for generating a predetermined light function, wherein the light-guiding device has a reflector (12), The reflector serves as a reversing reflector for a laser light source (11), wherein the laser light source (11) is oriented deflectively with respect to a horizontal and / or vertical plane and next to, between, and positioned above or below such that the light (17) emitted by the laser light source (11) is emitted in the direction of the reflector (12) and is redirected by the reflector into the main emission direction for generating a predetermined light function, wherein , the lens (19) is arranged to collect the light (17) of the laser light source (11) towards the direction of the reversing reflector (12), or the light guide has only one light distribution towards the main emission direction for generating the light function A lens (39), wherein the lens is arranged in front of the laser light source (31) along the main emission direction.

Description

technical field [0001] The invention relates to a lighting device for a vehicle, comprising a laser light source and a light guide device in front of the laser light source for generating a predetermined light function, characterized in that the light guide device has a reflector for the Reversing reflectors acting on laser light sources, wherein the laser light sources are oriented twisted relative to a horizontal and / or vertical plane and are positioned beside, above or below the reflector such that the light emitted by the laser light source The light is emitted in the direction of the reflector and is deflected by the reflector into the main emission direction for generating a predetermined light function, wherein the lens is arranged for focusing the laser light source in the direction of the reversing reflector, or the light guide has only A lens for generating a light distribution of the light function in the main emission direction, wherein the lens is arranged in fron...
