節能、減碳已經成為全球能源議題。同時，隨著LED的發光效率提升與價格降低，在能源短缺的現今，被視為將取代傳統光源，成為下一代新型光源。因此LED光源在照明市場應用前景備受看好。 本論文根據LED的光強度分佈特性及光度學原理做為四種照明模組設計的理論基礎。除此之外；我們參考CIE所發表關於室內工作場所照明規範來做光學設計並且利用ASAP 光學模擬軟體及DIALux進行照明方面的光學效能評估。 從模擬結果得知：(1)加上光學元件的照明模組可以降低眩光問題。(2) 室內照明應用上，使用照明均勻性高的照明模組可以更有效地節省能量消耗。 Due to being excessive development, the earth resource has showed up severe crisis, and the energy saving and carbon-dioxide emission reducing become a critical forum of world. Furthermore, the higher the LED luminous efficiency and consistently lowering the price of the LED force the LED being the new alternative for replacing the traditional light sources, and becoming the next generation sources. Therefore, LED light source being the most interesting and energy saving light source in the lighting market. There are four kind of lighting module was designed which design rule is according as luminous intensity distribution of LED and photometry in this paper.Beside, the CIE (The International Commission on Illumination) have release one standard which specifies lighting requirements for indoor work places. We are following this standard to do optical design and evaluate performance by ASAP and DIALux. The simulation result is (1)：When optical element is integrated to LED lighting module which can reduce the glare issue. (2) High illumination uniformity lighting module can save energy consumption more effectively for indoor lighting application.
