本論文主要針對非對稱二次光學透鏡做相關的研究。藉由環帶光通量的概念和二次全反射透鏡之數學式推導，可以簡單且快速地運算出相關座標以形成所需透鏡，並利用光線追跡軟體TracePro得以驗證設計結果。本文中，以等照度透鏡之設計為範例驗證環帶光通量設計的概念和方法。
本論文主要針對現行階梯教室整體照明環境照明品質欠佳的不足提出改善對策，並利用等照度配光概念設計出以非對稱光斑為目標的燈具，提升整體照明品質，提供使用者更加舒適的照明光環境。為了具體驗證提出之照明燈具對整體照明環境的改善效果，本文設計了二組對照組:以現行T5螢光燈管為照明的階梯教室和以對稱光斑LED光源為照明的階梯教室，並依據不同功能需求以調整相關照明指標作加權計算和評比，以選出最適合之燈具。研究證實，本文提出之非對稱光斑為照明的階梯教室可以提供最佳之照明品質。

The thesis focused on the design of secondary optical lens of asymmetrical distribution. The idea of zonal flux analysis provides us a fast and efficient way to analyzing the luminous flux of the sources and our targets while using the proposed secondary optical TIR lens design method to develop the luminaires. By using 3D model software SolidWorks we can build up our lens and verifying our design through ray tracing software TracePro. A TIR lens with symmetrical distribution was given in the thesis to prove the feasibility of the proposed methods. Moreover, due to the needs of designs to improve the lighting environments of current lecture halls, we designed two luminaires with asymmetrical distribution for the blackboard and the desks. A lecture hall was further built within lighting design software DIALux to show the results of the luminaires. To guarantee the proposed luminaires were ideal, an evaluation system was set up and two control groups were compared, with one using conventional T5 luminaires and the other using a LED blackboard luminaire with asymmetrical distribution and a LED desk luminaire with symmetrical distribution. The designed evaluation system mainly focused on the feeling of human so as to take uniformity and UGR more seriously. The results showed that the proposed luminaires provide better lighting environment for the lecture hall.
