Abstract:	本論文中，我們建立複眼透鏡系統之模型，其該系統可將發光二極體所發射出之光線進行分配，用以得到高均勻的照明光形。首先，我們根據中場原理對歐司朗的光源CQAR 以及CR7P 建立光源模型。接著依據我們所建立的光源模型，設計出光整合系統並分析在不同種條件下，如何獲得一均勻的照明光形。藉由模擬與實驗結果的比較，我們驗證所建立系統模型的準確性。最後，我們針對尚未通過複眼透鏡時的非均勻的照明光形，進行光整合系統的優化，用以得到最佳均勻度的光形。 In this thesis, we model a system that uses fly’s eye lens to redistribute light from an LED source to obtain high uniformity illumination. First, we establish successfully two optical models for Osram CQAR and CR7P based on mid-field concept. By using these two light source models, we design the beam integrator system and we analyze several parameters for the system to get a uniform pattern. We demonstrate our model by comparing our simulations with a real optical system. At last, we optimize the system to get the best uniformity when the light pattern before the fly’s eye lens is not smoothing
