Abstract
The present invention relates to a lighting device for vehicles. The lighting device has a flat optical waveguide containing two opposing flat sides, a light input surface for the entry of light, and a light output surface for emitting the entering light at a light output side of the flat waveguide. The light input surface has a central input section disposed in the main beam direction in front of the light source, and an outer input section adjacent thereto. The central input section and the outer input section are shaped such that a first sub-light bundle of the light striking the central input section strikes a central region of a sub-surface of the light output surface disposed in the main beam direction in front of the light input surface after being reflected at the flat sides. A second sub-light bundle of the light source, striking the outer input section, strikes an outer region of the same sub-surface, adjacent to the central region.
