REDUCED-FOOTPRINT ILLUMINATION SYSTEM USING HIGHLY-EFFICIENT OPTICAL COLLECTION AND REFLECTION SURFACE(S) AND METHOD FOR MANUFACTURING OPTICAL ELEMENTS USED THEREIN

摘要

An improved optical collection and transmission surface includes a plastic mold injection surface including staggered multiple transmission sites each with a recessed portion in which incident light is not lost during reflection towards the propagation surface. A device implementing the surfaces is plastic-mold injected of high quality acrylic at in a preferred embodiment and can be economically optionally polished or finished to achieve desired quality surfaces.
