【摘要】 本文介绍一种折反式ＬＥＤ聚光器件。这种器件可将ＬＥＤ发光管芯向侧面发射的光全反射聚光。同时将向正面发射的光折射聚光，聚光效率较一般的折射聚光ＬＥＤ高２倍以上更多还原

【Abstract】 A kind of catadioptric LED light condensing device is represented in this paper. It can totally reflect and condense the lights which emit towards side direction, also by refraction, it can condense the lights in right direction. The lights condensing efficiency is at least two times more than other refractive condensing LED.更多还原
