The unit has a light guiding body expanding in a light propagation direction (15), where the body is arranged optically downstream to a LED (20). A base surface (71) and a cover surface (51) are formed in a longitudinal section, where the surfaces limit the body. The base surface has a curved section (62), which is positively curved relative to the direction, and the cover surface has another curved section (76), which is negatively curved relative to the direction. The curved sections limit a light inlet surface of the body, where one of the curved sections has an inflection point (66). |
