本論文主要是在探討以LED為投影機光源時，其收光元件利用複合式拋物面收光器(Compound Parabolic Concentrator，簡稱CPC)原理之設計流程，並使用此流程找出最佳化之收光設計，並實際製作出收光元件，再搭配LED晶片封裝成收光模組。最後將此收光模組應用於市售投影機之光機系統，分析其輸出、系統效率及均勻性In this thesis, we study to optimize the optical system with RGB LEDs. We start from the design of the compound parabolic concentrator to collect the light from LEDs and maintain the etendue requested by the optical system. At the same time, we simulate the optical distribution with specific LED arrangement. We compare the experimental measurement with the simulation and finally design an optical module for the LED projection system, where the system efficiency as well as uniformity are analyzed.
