Abstract:	本研究是進行全彩發光二極體模組，遠光場之分光曲線量測系統研製。卽量測全彩發光二極體之發光源，在一定距離外的光強度分佈。目的是檢驗所照明設備，是否有發光不均的缺陷，以達到品質管理，及製程缺陷等問題之改善。一般遠光場量測儀，均採用單感測器，及相當多之轉動件來達成量測目的。如此不但量測時間較長，且系統複雜不易維護，成本也高。因此本研究是將複雜之轉動件，簡化成單一轉動方式之機構，如此可在系統維護，及製作成本上減少許多，可大大提升遠光場量測儀之整體效率。 The purpose of this research is to set up a far field measurement system for light emitting devices. The system used thirteen (13) photo-detector array modules to form a 90 degree arch with a diameter of 63.2cm. Each module comprised eight photo-detectors
