[[alternative]]Reflector Design for LED Luminaires

碩士電機工程學系[[abstract]]由於發光二極體（Light Emitting Diode, LED）具有指向性的特性，若直接應用於一般照明系統中，則會產生照度分佈不均勻的現象，而必須借助於二次光學設計，以達到均勻的照明。本論文提出一個應用配光曲線的概念於LED照明模組之設計，藉由所設計之反射罩並結合高功率LED來實現所欲達成之配光曲線分佈，以期在目標照射面產生均勻照度分佈並符合CNS照度規範。本論文之LED照明模組主要應用光學軟體TracePro進行設計，並透過該軟體來探討LED模組陣列於整體目標照度面上的影響，進而決定效率最佳的LED照明模組陣列，以產生符合法規規範的照度分佈，並能有效地減少能源的損耗。由光學模擬之結果顯示，本論文所設計的各種排列之照明模組陣列，其光學效率可達96%，而照度均勻度在0.7以上。[[abstract]]Since light emitting diode (LED) has the characteristic of directional property, it is not suitable to be directly applied to general lighting systems, otherwise, it will cause the phenomenon of uneven illumination. Thus, a secondary optics is required to achieve uniform illumination. In this thesis, an LED illumination module design is presented based on the concept of the candle power distribution curve. Therefore, the wanted distribution can be implemented with an appropriately designed reflector and a high-power LED so that the goal to achieve uniform illumination distribution and to conform to the CNS (National Standards of the Republic of China) standard can be obtained on the target plane. This lighting module is designed using the TracePro software, and the influence of the arrayed LED illumination modules on the whole target plane is also explored with the same software. Finally, the optimal LED illumination-module array can be determined to produce the intensity distribution conformed to the CNS standard, and hence the loss of energy can be reduced effectively. The optic simulation result shows that the optical efficiencies of the various illumination-module arrays in this the thesis can achieve 96%, and the uniformity of illumination is up to 0.7
