隨著LED發光效率的提升，均勻性、人眼眩光及燈源演色性問題將是未來研究的重點，因此，本計劃所發展的照明技術將針對上述問題提出探討。預計將於第一年計畫中，利用LightTools光學軟體模擬室內照明之照度，再導入LED與太陽光混合照明儲能系統加以模擬分析，並設計防眩光照明。再將桌平面所模擬得到的照度資料由Matlab個別計算照度平均值與均勻度，並由DIALux室內照明設計3D模擬軟體模擬實際情境並分析環境色溫，最後再計算日光燈與LED燈，太陽光與LED混合照明儲能系統所使用之功率及經濟效益並進行比較。藉導引太陽光之後，預計可節省許多照明之用電量並還可進行額外的儲能，最後計算各種日照狀況時的使用功率及經濟效應，並進行相關元件進行開發。計畫預計於第二年初期收集傳統大型室內照明設計之方法，研究傳統燈源與燈具的特性與效率，並針對傳統大型室內照明進行檢討；中期時，我們將設計開發適合之大型室內高功率LED照明。同樣先以LightTools設計LED光源進行配光曲線與照明照度之模擬，再由DIALux室內照明模擬軟體模擬實際照明情境，並分析該大型室內照明之狀況，預計將於第二年個別設計符合照度標準且均勻度佳的照明環境，同時將設計出光線夠亮、夠集中且對運動選手、表演者或是觀眾不會產生嚴重眩光之舒適照明環境。 As the rapid development of the efficiency of high power LED has been improved, the problems of uniformity, glare, color temperature and color rendering are all the important issues that we want to figure them out. Also, the global warming problems are getting worst and worst, the development of renewable energy will be the next world-wide topic in the near future, sunlight energy is one of them. In the early 1st year, we plan to present a new design of sunlight/LED hybrid illuminating and solar-energy saving system for indoor illumination. We design an light integrating collector to uniform the collected sunlight that collected by concentrator, and LED light, and then lighting our indoor spaces in Lambertian form after scattering by a diffuser. We also simulate the illumination and calculate the efficiency and find that the sunlight/LED hybrid illumination is better than that of traditional lighting. Finally, we will build them in scale sample. In the 2nd year, we plan to design the sunlight/LED hybrid illuminating and solar-energy saving system for high-power LED lighting that use for wide range interior spaces, such as gymnasium. We will consider the illuminated environment for athletes, audiences, and photographers when designing the brightly and comfort viewing environment. Finally, we will build them in scale sample, too. 研究期間：10001 ~ 10012
