Abstract

For solving the problem of non-uniformity of light emitting diode(LED) illumination, based on basic principles of non-imaging optics and geometric optics, the design procedure of a LED reflecting secondary optical system was deduced. Then a LED reflecting secondary optical system was designed and its illumination uniformity was simulated. Aiming at the problem reflected by the simulation result, the designing procedure was improved. Then the secondary optical system was redesigned, the result of simulation shows this optical system can achieve the illumination uniformity.
