Abstract:	本計劃目標為將高效能白光LED以應用於室內照明，目的是在提高LED的信賴性與發光效率，同時使LED應用於室內照明上能夠在光學品質、色彩品質與人因科技上皆能達到良好的表現，以加速LED應用於室內照明。本計畫總共分為總計劃與四項子計畫：子計畫一為高效能LED封裝，其整合發展“高功率LED晶圓級封裝製程技術開發＂，同時開發高功率LED熱模擬技術，以達成一階封裝熱阻低於1 ℃/W的目標。子計畫二開發高演色性多色螢光粉的計算鋪陳技術，使螢光粉之使用在演色性與明視效率的雙重考慮下在效率上獲得最佳化，同時配合螢光粉鋪陳技術優化發光光型，使得LED演色性(CRI)超過92 (冷白CCT: 5500K-6500K)、95(暖白CCT: 2800K-3200K)、空間色偏為暖白在±40K以內、冷白在±100K以內。子計畫三高效能LED室內燈具光學設計，將以世界領先水準之精準光源模型與精準散射腔體模型結合多年光學設計之經驗，設計高效率低眩光之泛光燈具，其光學效率將達90%，並且預計於2013年達成140 lm/W；此外，將發展RGB混光燈具，使其光學效率達到70%，並搭配子計畫二之發展之智慧電控技術用以調變混光燈具之不同色溫。在子計畫四LED智慧照明人因科技上，將建立之光學眼球模型及人因視覺測試環境與實驗流程，探討人眼視覺模型與眩光評價技術、LED藍光成份對視覺生理之影響以及中介視覺適應之節能照明調控技術，將本計畫之高效能LED燈具導入更具人性化之使用階 The three-year project is aimed to develop high-efficiency and high-reliable white LED to the application in indoor lighting. The objective is to provide LED solid-state lighting (SSL) with high optical quality, high color rendering index and human-factor technology, and to speed up the practical application of LED SSL to indoor lighting. The project contains four sub-projects besides the leading sub-project. The first sub-project is for high-efficiency LED package technology, which will establish the chip-scale improvement, the developments of "high-power LED wafer level packaging process technology," "thermal resistance measurement," and "wafer-level simulation technology" is to achieve lower than 1 ℃ / W of thermal resistance in the first-order package. In the second sub-project, we will expand the calculation and special distribution for several phosphors to get high CRI in the second sub-project. After our optimization, the CRI of LEDs will be higher than 92 (CCT: 5500K-6500K) & 95 (CCT : 2800K-3200K). Also, the △CCT will be lower than ±40K for warm white ±100K for cool white LEDs. The third sub-project is about the optical design in LED indoor lighting in extreme high quality. The team members will apply the world-leading techniques in optical design for LED SSL to develop indoor luminaires with low glare with high optical efficiency in diffusing and projection luminaries. The optical efficiency will reach 90% and above, and the luminous efficacy of system will reach 140 lm/W. Besides, the optical efficiency of the luminaire with RGB color mixing will reach 70%. Combing the electric control technology by the second sub-project, we can modulate different color temperature of the luminaire with RGB color mixing. In the fourth sub-project, the optical human-eye model and the visual evaluation platform will be utilized. Also the development of the human vision model and glare-evaluation technique, investigation of LED blue-spectral content to visual and biological effects, and development of energy-saving lighting technique based on mesopic vision model will be successfully achieved. According to the fourth sub-project, the indoor luminaire with high quality will be more practical for human being. 研究期間：10001 ~ 10012
