Abstract:	本論文主要從照度的觀點來探討陣列光源在不同距離下的能量變化及分佈，並以平方反比定律為基礎來定義其遠場距離，進而界定出其中場之範圍及歸納其在中場之照度特性。而在光源的選擇上，亦不同於市售的典型朗伯光源陣列，本論文利用不同散角之單一光源所組合而成的兩種非典型陣列光源來進行分析，提供在照明燈具的設計上更多元化的參考方向。;In this thesis, we discuss the illuminance change and distribution of light sources array at different distances, and the far field distance is determined according to the inverse square law. In such a way, the range of mid-field can thus be well clarified, and the characteristic of illuminance in mid-field is explored in the same time. We use two kinds of atypical array light sources with different FWHM for a single non-Lambertian light source. By further analyzing the central illuminance distribution, some novel but essential design rules are proposed for the reference in the lighting design.
