High efficiency light source utilizing co-generating sources

摘要

A general service incandescent lamp including a housing with electrically conductive base (s); a transparent envelope; a radiation discriminative reflective film reflecting wasted radiation for recycling; a electrically driven filament; wherein an improvement is a new use of lightweight low thermal capacity insulator of fibrous ceramic material spatially formed to shade the lamp base from filament and/or reflected energy from a reflective film; wherein an improvement is to use the ceramic to shape the output beam to the solid angle of radiation; wherein an improvement contains a low thermal capacity insulator with candoluminescence material that when thermally exited emits radiation via candoluminescence improving the lamp's efficacy and color; wherein an improvement contains a larger optical spot size focusing requirement for the reflective mirror as compared to the spot size formed by the lamp's filament cross section, wherein an improvement is use of a polarized discriminative reflective film.
