Vorrichtung zum Bündeln und Übertragen von Licht

摘要

An apparatus includes a reflective surface (30) for high efficiency collection, transmission and emission of light. Light collected by ellipsoidal and hyperboloidal portions (32, 34) of the reflective surface (30), is directed into a light guide (28). Additionally, a paraboloidal portion may be added and used in combination with a lens element to distribute the light reflected by the reflective surface in a beam pattern. When used as an emitter lens profile is smaller than the overall diameter of the reflective surface. When used as a collector (20) the reflective surface (30) receives and concentrates light onto the end of a light pipe. <IMAGE>
