摘要: 近年來由於環保及節能意識日漸抬頭,歐美日等先進國家逐漸重視這議題,其中LED具有省電、無汞汙染等優點,可以用來取代傳統的白熾燈及日光燈,因此提升LED的效率為大家努力的方向。 本論文使用光學模擬軟體SPEOS進行光學的設計及模擬,利用改變LED封裝的幾何形狀去控制LED的光形,再進行尺寸的最佳化,讓LED的輸出功率達到最高。在LED光形半功率全角為120度、100度、80度和60度時,分別可以提高LED的輸出功率10.97%、9.95%、7.49%和4.39%;透過封裝尺寸的優化,可以提高LED的光萃取效率,達成提高LED效率的目的。
The developed nations lately emphasize the concepts of energy saving and environmental protection; Therefore LED gains saving much attention due to its advantages, such as no mercury pollution and low power consumption. Still the key issue is to improve the lighting efficiency. This thesis using optical design and simulation software called SPEOS to model the various directivity LED lamps and optimize their geometrical parameters to extract maximum output power. It is shown that for FWHM (Fall Width Half Maximum) angle equal to 120 degree, 100 degree, 80 degree, 60 degree, the improvement of power is 10.97%, 9.95%, 7.49%, 4.39% respectively. Using the methods which optimize the geometrical parameters can achieve our goal.
