The light conductor has a light entry face at one or both ends, a light exit face (5) extending along its axis and a light reflecting surface (4) facing the light exit face, with at least one de-focusing side face (6,7) between the light exit face and the light reflecting surface, e.g. a pair of concave de-focusing side faces positioned symmetrical to the light exit face and the light reflecting surface. |
