本論文中，我們設計了符合歐洲汽車近燈法規之光學系統。在光學系統中，我們首先安排LEDs 的位置並且使用複合式拋物面收集器當作一次光學元件，此一次光學元件不僅增加光粹取效率並且在保持Etendue下增加發光面積。我們也設計了一顆非圓對稱結構的成像透鏡，此透鏡可以增加光形之對比度。我們製作出此光學系統並且對於實驗與模擬來做比較。最後我們分析此光學元件的容忍度。

In the thesis, we design an optical system to meet the ECE regulation for the automobile low beam. In the optical system, we first design the arrangement of the LEDs and using a compound parabolic concentractor to serve as the first optics, which is to increase light extraction efficiency and enlarge the light pattern with keeping the etendue. We also design an imaging lens with an asymmetric structure to increase the contrast of the light pattern. We fabricate the design optical system and the comparison between the simulation and measurement is made. Finally, we analyze the alignment tolerance of the optical system.
