    • 本論文中，我們選用高功率白光LED為光源，設計一在俯角15˚時，投射出矩形光型的燈具，此燈具以兩組對稱擺放時，能夠在目標面上達到高均勻度。一般架設於球場四周的燈具，為了將光投射到更廣的範圍，會將燈具傾斜一角度，而造成原本矩形之光型會因旋轉而使光型變為一個梯形的形狀。在本論文研究中之一重大目的，是將此倒梯形之光型修正回原本之矩形光型以達成上述之照明效果，此外我們也由實驗驗證模擬之精準度。根據本研究中之設計結果，我們將多個燈具陣列式配置，探討在不同的場館照明下空間中的照度分布以及光學有效利用率，如：羽球場、排球場以及游泳池等，皆能在各個場地中達到高均勻度。最後，探討其燈具之公差。

    In this paper, we design a lamp with high uniformity and rectangular light pattern based on power-chip white LEDs. Furthermore, the distortion of pattern caused by the depression angle of the lamp is compensated in our design. According to the result of this design, we can consider the array of the lamps and discussing the illuminance distribution in different stadium lighting, such as: badminton court, volleyball court, and swimming pool. Finally, we will analyze the tolerance of this lamp.
