Lighting device for vehicles, has curvature of elongated light guide that is limited in extension direction, where radius of curvature of light guide is greater than double transverse extension of light guide

摘要

The lighting device has a light source (2) and an elongated light guide (1) associated with the light source, where the light guide extends in its extension direction (E) for forming a curvature (8). The light guide has a circumferential surface. The curvature of the elongated light guide is limited in the extension direction. The radius of curvature (r-L) of the light guide is greater than double the transverse extension (d-L) of the light guide.
