摘要:	本論文首先針對現今國際球場照明情況進行探討，以國際單項運動總會聯合會所制定的羽毛球場照明標準為準則，採用LED做為光源，提出一具有光塑形效果之透鏡及其所衍生出之高性能球場燈照明設計，該透鏡之光學效率可達 77.6%。其次，於本論文中，將此高性能燈具與市售LED 燈具分別以兩側排列、四角排列以及環形排列方式之國際球場進行模擬分析，並提出相對應的照明改善方案。最後，根據模擬分析，採用本論文所提出的高性能燈具之國際球場照明效果，球場平均照度可高於 1000 lx，均勻度則大於 0.9，並且在球場及其周圍 36 m × 21 m 之範圍內的光學利用率高達 60 %，不僅可以符合國際規範的照明標準要求，亦可達到抑制眩光、增加球場照度與對比度、及達到節能減碳之效益。;In the thesis, according to the lighting condition of several international sport fields and the badminton lighting standard by SportAccord, we used LED as the light source and proposed a lighting design with a specific lens for beam shaping. The optical efficiency of the specific lens was 77.6%. Besides, we introduced the designed luminaire and general commercial lamps to international sport fields with three different geometry arrangements, such as at two sides, at four-corner, and along ring structure. The lighting performance in these sport fields were analyzed. Finally, with use of the designed luminaire, the average illuminance and the uniformity on the ground of sport field were higher than 1000 lx and 0.9, respectively. The optical utilization factor at the region of 36 m × 21 m was higher than 60%. Therefore, the proposed luminaire with beam shaping effect not only fits the lighting standard of international sport field but also achieves anti-glare property. Also, the illuminance and contrast across the sports field were enhanced, so that the design perform high-quality lighting and energy saving.
