Lighting device for vehicles
A lighting device for vehicles with a multitude of light modules, each comprising a light source arranged on a substrate and a lens arranged at a distance to the light source for the creation of a given light distribution. A fixed side light module and a fixed main light module are provided as a light module. The side light module has an asymmetric lens, so that a light beam radiated by the side light module creates a side light distribution extending a main light distribution created by the main light module in the lateral direction.
1. A lighting device for vehicles comprising:
at least one light module comprising:
a fixed main light module including:
a light source arranged on a substrate, and
a lens arranged unobstructedly at a distance to the light source, said lens for the creation of a given light distribution; and
a fixed side light module adjacent to the fixed main light module including:
a light source arranged on a substrate,
an asymmetric lens arranged unobstructedly at a distance to the light source so that a light beam radiated by the light source of the side light module creates a side light distribution extending a main light distribution created by the main light module in the lateral direction, and
wherein the light source of the side light module is arranged offset in the horizontal direction relative to an optical axis of the main light module, so that the side light distribution of the side light module abuts on the main light distribution of the main light module in the horizontal direction.
2. The lighting device according to claim 1 wherein the asymmetric lens of the side light module has a cut edge at a distance relative to a vertical center plane of the asymmetric lens being smaller than a distance of an opposite outer edge of the asymmetric lens relative to the vertical center plane.
3. The lighting device according to claim 2 wherein a cut face abutting on the cut edge of the asymmetric lens of the side light module has a depth relative to a base plane of the asymmetric lens which is larger than a half of the overall depth of the asymmetric lens.
4. The lighting device according to claim 1 wherein the side light module can be switched on or off depending on a steering direction of the vehicle.
5. The lighting device according to claim 1 wherein the side light module and the main light module each have a lens holder being fastened on a heatsink carrying the substrate for the respective light source.
6. The lighting device according to claim 1 wherein the light source of the side light module and of the main light module is embodied by a straight row of semiconductor-based light sources arranged next to one another, wherein the row of the semiconductor-based light sources of the side light module is arranged rotated by an angle relative to the row of semiconductor-based light sources of the main light module.
7. The lighting device according to claim 1 wherein the lens of the main light module is embodied plano-convex and that the asymmetric lens of the side light module is embodied partly plano-convex, wherein the asymmetric lens of the side light module has a cut-off lateral area.
8. The lighting device according to claim 1 wherein the side light module is arranged offset in parallel relative to the main light module in a common housing.
