Abstract (en)
[origin: WO2017207683A1] Optical lenses for illumination purposes (L) are proposed, comprising a lateral surface (C) and a light exit surface (B), wherein the underside is shaped in a plane fashion and has an optical relevant cutout for receiving a light source, which is distinguished by the fact that the lens (L) has a lateral surface (C) that is wholly reflectively coated, and has a light exit surface (B) having the two vertices (b1) and (b2), wherein (b1) and (b2) represent respectively the highest and lowest vertices upon the transition from the light exit surface (B) to the lateral surface (C).
