摘要

本研究主要探討平板燈蝠翼光形最佳化與燈具配置關係，以最佳之工作面照度均勻度為目標，同時考慮眩光指數與燈具佈燈問題，以找出相對合適之蝠翼光形。目前，蝠翼光形可增加工作面均勻度之特性已被接受，但是對於標準蝠翼光形形狀參數之訂定仍不明確。除此之外，由於一般設計者對於蝠翼光形對應之光品質影響了解有限，使得一般蝠翼光形燈具所測得之眩光指數仍然過高。因此，本研究目的在訂定蝠翼光形參數與輸出光品質之分析，並進一步探討不同長寬比場域中最合適蝠翼光形參數，以達到最少燈具數量並同時兼具高品質光輸出之室內燈具設計。

關鍵字詞：蝠翼光形、照度均勻度、統一眩光指數

The Relationship Between Batwing Distribution And LED Fixture Mounting Arrangement

Abstract

In this study, an investigation of the relationship between batwing distribution and fixture mounting arrangement is proposed. Over the past few years, the idea of batwing distribution can improve the work-plane illuminance uniformity have been accepted conceptually. However, little attention has been given to the point on defining batwing distribution. Based on the procedure of optimizing illuminance uniformity in different room sizes, Unified Glare Rating (UGR) and the luminaire arrangement in indoor environment, the most suitable batwing distribution has been defined. By using this method, someone can use the suitable fixture number to improve the lighting environment. Therefore, an energy saving lighting environment could be realized.

Keywords: batwing distribution, illuminance uniformity, unified glare rating
