"由於發光二極體的照明亮度會隨著溫度升高而大幅降低，因此散熱將會是影響發光二極體照明效率的重要參數。計畫中擬以熱電偶量測不同功率LED 晶片與不同散熱模組尺寸上之基板與散熱片的溫度，並以照度計量測其散熱效率對照明亮度之影響。此外，為評估其之精確性，計畫中亦將採用格點對應與截斷級數兩種數值方式，進行比較評估。若上述實驗結果與模擬數據之誤差超過5%，則進一步導入失效模式實驗計畫法，以密閉絕熱空間之溫差推估熱傳率，進一步將兩種實驗方式數據與兩種數值分析結果作比較。經由計畫之研發，期望能提升大功率LED 晶片引起之高溫的散熱效能，進而提升亮度達到提升照度及節能之效益。"
"Since the brightness of LED will rise with the temperature of chips decrease, so it is the important parameter of influencing the lighting efficiency of LED to dispel the heat. The proposal will measure the temperature of LED chips with different power and fin assembly with different sizes by using thermocouples. And measure the influence of the effect of heat transfer on the brightness by using the illuminometer. Besides, in order to estimate the accuracy of the research, the proposal wills comparison the accuracy by using the both numerical methods of Point-Matching method and Series Truncation method. In case of the experimental data and numerical results to exceed precision of 5%. The project will further introduce the experimental design of Failure mode and effects analysis (FMEA). And predict the heat transfer rate via the temperature different of space of heat insulation. Through the analysis of the proposal, expect to be able to improve the heat dissipation efficiency under the heat generation of high brightness, high power LED, and then improve the luminance and energy saving."
