Abstract (en)
[origin: WO2014125115A1] An optical unit (20) for influencing the light emission of an LED light source (150) comprises a lens body (1), which has a light-injecting surface facing the LED light source (150) and a light-emitting surface (10) opposite the light-injecting surface. A jacket surface (8) of the lens body (1) causes total internal reflection at least for some of the light rays entering via the light-injecting surface, and the light-emitting surface (10) is divided into at least two separate emission regions (101, 102, 103) which are formed in such a way that beams emitted by means of said emission regions (101, 102, 103) each illuminate a substantially identical region of a surface (200) to be illuminated that is arranged in front of the optical unit (20).
