LIGHT-INFLUENCING ELEMENT FOR INFLUENCING THE LIGHT EMISSION OF ESSENTIALLY POINT LIGHT SOURCES

摘要

An optical element for influencing the light emission of a substantially punctiform light source, in particular an LED. The optical element has a truncated pyramid- or cone-like basic shape with an approximately rectangular base that forms a light-emitting surface, and the optical element also has a cover surface which faces the light source and which forms a light inlet surface. Lateral face regions of the optical element, the regions extending from the cover surface in the direction of the corners of the base, are formed by flat or rotationally symmetrical surface regions.
