摘要

隨著人們對永續發展的綠建築理念的瞭解與接受，越來越多的人開始關心居家和工作場所裡的能源使用效率。一種名為太陽能自然光追蹤照明系統，可藉由持久性增強室內照明強度與光線品質方式，達成可觀的降低使用照明電力，可滿足上述節能減碳的需求，並且已有逐漸的廣被使用在室內照明中的趨勢。本研究目的旨要以實驗方法對太陽能自然光追蹤照明系統特性能進行有系統的研究探討。研究第一階段是以實作方式研製一太陽能自然光追蹤照明系統，並進行運作可能性研究；第二階段建立實驗測試系統，以實測方式紀錄並探討分析一天室內動態自然光照明強度分布特性。此外並探討不同設計參數如導光板材質、放光板材質、追日系統機構靈敏度及天候環境等對照明品質性能的影響。
實驗結果顯示：(1) 本追日系統有10度偏差量，導致18%的照明衰退率; (2)室內照明照度為戶外日射照度的10% (100W)。(3)單盞太陽能追日式自然光照明每年節省電能292度。

With the increasing awareness of sustainable and green building, more and more people are concerned with the efficiency of energy use at home and at work. A solar tracking skylight illumination system, which enables us to conserve energy by producing increased interior light levels for a longer duration than normally possible, can fit to the above need and have widen been used in the indoor illumination gradually. In this study, an experimentally investigation is conducted to explore the dynamic illuminative performance of solar tracking skylight illumination system. In the first stage of this research, a tracking skylight illumination system is tried to be developed by implement. In the second stage, the experimental test apparatus is set up and the basic lighting intensity distribution of skylight illumination system will be examined. In addition, the effects of various design parameters, e.g., the material of reflective panel and diffusive panel, the sensitivity of tracking skylight illumination system and skylight condition, are also analyzed. The results show that (1) The maximum amount of deviation of this solar-tracking system was found to be up to 10° from the accurate sun path through the whole year, which results in 18% decay in lighting intensity；(2) Illumination of indoor lighting is 10% (100W) of outdoor solar radiation intensity; (3) A set of solar-tracking skylight system can save electronic power about 292 kw-hr per year.
