Abstract:	在本論文中我們使用藍光雷射二極體激發黃色螢光粉產生白光雷射照明，並提升白光雷射照明之效率與其輸出能量。首先遵循於由孫慶成教授之固態照明團隊所建立之準確螢光粉光學模型流程，針對藍光雷射二極體應用於螢光粉之特性分析。再者，設計半球反射杯之光子循環機制透過光子回收方法，使整體白光雷射照明效率提升，並使用建立完成之螢光粉模型，進行模擬與實驗結果之佐證。最後，使用角度多工方式將三支雷射光同時輸入系統架構之中，並且分析在控制系統光展量時，能以線性疊加之方式輸出能量，再搭配使用之散射架構方式解決整體白光雷射照明之空間色偏均勻度。;In this thesis, we utilize blue laser diodes as light sources to excite yellow phosphor and enhance output power and efficiency for phosphor-converted white light laser lighting. We started from following the phosphor optical model developed in the laboratory led by Dr. Ching-Cherng Sun to analyze the optical characteristic of yellow phosphor applied on blue laser diode. Second, we designed a hemisphere reflector to perform photon-recycling to increase the optical efficiency of the system setup. In addition, the experimental measurement was compared with the simulation with the phosphor model. Finally, we designed angle-multiplexed laser injection to linearly increase the output flux with holding the étendue of whole system. Finally, we reduced the angular correlated color temperature deviations of the laser light source module with use of various diffusers.
