Abstract
A lighting device for vehicles has a light source and an optical waveguide, which itself includes a first optical waveguide segment with a light entry surface for light from the light source, a second optical waveguide segment with a light emission surface for the light. The emission surface has an optical structure, and a reflection segment between the first and second optical waveguide segments that has a reflective surface that reflects the light entering the optical waveguide toward the second optical waveguide segment. The light emission surface has an edge without an optical structure. The reflection surface has diffusion elements at the edge where part of the light entering the optical waveguide is deflected toward the second optical waveguide segment, and is emitted at the edge of the light emission surface in the second optical waveguide segment.
