摘要:
An apparatus includes a reflective surface for high efficiency collection, transmission and emission of light. Light collected by an ellipsoidal and hyperboloidal portion of the reflective surface is directed into a light guide. 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, the reflective surface receives and concentrates light onto the end of a light pipe.
