Resolution lens i.e. light-diffusing cylindrical lens, for light source i.e. LED, of vehicle, has central lens section with light inlet surface exhibiting shape of saddle surface that has curved concave shape along longitudinal extension

摘要

The lens (1'') has a reflection surface (8a) arranged between a light coupling surface (3a) and a light uncoupling surface (7) to reflect a mixed light to a reflection section (10). A longitudinal extension larger than a transverse extension is formed in a plane that is arranged orthogonal to an optical axis (4) of the resolution lens. A light inlet surface (2) of a central lens section (9) exhibits the shape of a saddle surface, where the saddle surface has a curved concave shape along the longitudinal extension.
