摘要

從氮化鎵GaN-LED被開發完成後，現今已朝白光LED發展。日本預估到2010年白光LED的發光效率屆時將超越日光燈，其在照明市場之發展深具潛力，前景看好。白光LED與傳統光源相比較具有諸多優點，其工作原理簡言之，就是利用無機固態LED製程技術，再藉由螢光粉體來達到混色而發出白光。而白光LED照明能否普及化之最大關鍵就在於發光效率與價格；目前其應用領域有：手電筒、儀表背光源或前置光源、交通號誌、交通工具內部照明等。
本篇論文主要是設計一透鏡陣列和非球面光學元件結合的複合式透鏡，對發光效率與均勻度作改進，而應用到LED照明系統上。首先，由簡單之近軸光線追跡原理推導，以便定出研究之LED照明模組設計所需的系統參數。再利用光學設計軟體對已推導出的初始照明系統模型作優化，設計出一實用之照明模組。

Since gallium nitride of light-emitting diode（GaN-LED）was developed, white-light LED has become a focused now. Its illumination efficiency will be higher than fluorescent lamp till year 2010, predicted by Japan. In the future, white-light LED must have considerable potential in the illumination market. It has much more advantages in comparison with traditional light-source. Its work principle was based on the process of inorganic-solid LED and mixture of phosphor powder to radiate white light. Popularization of white-light LED illumination or not is determined by efficiency and cost. Its applications include flashlight, source of fascia, traffic lamp, and internal illumination of traffic tools.
In this thesis, the object is mainly to design a lens array combined with an aspheric optical element to be a compound lens array to be used in the LED illumination system, that can improve the illumination efficiency and the uniformity. First, the parameters to decide the LED illumination module are derived by means of paraxial-ray tracing. Second, the initial illumination system module is optimized by using optical design software to design an illumination module of a practical use.
