ILLUMINATION SYSTEM AND METHOD FOR RECYCLING LIGHT TO INCREASE THE BRIGHTNESS OF THE LIGHT SOURCE

摘要

An illumination system for increasing the brightness of a light source of the present invention includes an optical recycling apparatus 200 coupled to a light source 100, preferably a light emitting diode (LED), for spatially and / or angularly recycling light do. The optical recycling apparatus 200 may use a reflector or mirror 400 to spatially recycle a portion of the light emitted by the LED to the light source 100 and / And increases the brightness of the output of the light source 100.
