因應全球暖化和能源危機對再生能源的需求，太陽能成為節能技術的發展重點。而隨著照明科技的演進，照明消耗能源佔人類活動總耗能之比例亦明顯提升。因此，如何將太陽光譜中的可見光波段應用於照明亦成為熱門研究議題。然而，當太陽光應用於照明時，光源易受天氣、季節、…等影響而擾動，因而需要輔助光，以使光源之照度及顏色穩定。且為便利控制光特性，常以易於電控的固態照明光源(如LED)作為輔助光源。此法雖可提供足夠的照度與光色，但對於照明而言，柔和均勻的光線分布亦是不可或缺，是以發展均光技術係太陽光照明系統之重要研究課題。 由於照明所需之太陽光譜為可見光波段，故本研究先以奈米濾光元件將太陽光譜中的可見光取出。再以發光二極體(LED)光源作為補償光，使之與太陽可見光於混光模組中以適當配比混合。並於混光模組中設計均光元件，使太陽可見光與LED光可均勻混合，以實現均勻度良好之舒適輸出光。本研究預計達成均勻度達80%以上且光效良好之太陽光奈米均光照明系統。 ;Along with the development of the lighting technology, lighting takes an increasing portion of the world energy consumption. Thus, applying sunlight for lighting becomes have drawn high attention in recent years. When sunlight is utilized as a light source, it’s easy to be fluctuated because of the weather and season and auxiliary light source is required to stabilize the illuminance and color. For the flexibility of the control, the LED is a good candidate as the auxiliary source. Since the uniform illumination is an important factor, the research of homogenizing the light mixed from sunlight and LEDs is an important topic. In this research, a nano-filter is used to take out the visible portion of sunlight for lighting application. Then the LED is exploited as the auxiliary light source and mixed with sunlight. A homogenizing component will be designed to make the mixed light uniform and to realize mild illumination. The aim of this research lies in a nano-filter-involved solar lighting system with the uniformity of higher than 80%. ;研究期間：10501 ~ 10512
