近年來，由於溫室效應與能源短缺危機，環保意識逐漸抬頭，綠能產業在全世界受到重視，而在綠建築之應用方面，為了節約能源與健康照明，一種新技術能將太陽光直接導入室內稱為日照系統，開始被應用，本團隊開發一日照系統，稱為自然光照明系統。在自然光照明系統中，常使用稜鏡陣列結構，負責將太陽光收集並導入室內。本論文以現有集光模組元件之設計概念為基底，針對其可改善之處，進行優化設計，建構出一新式集光模組。在太陽光正向入射之情況時，最大集光效率成長倍數，相較於現有集光模組元件，可以達到2.75倍。在太陽光斜向入射時，新式集光模組元件也能有更佳之整體效率表現。

In this paper, we present an optimized design for the light collection elements used in a daylighting system. We design each surface of the individual light collection element with appropriate orientation and combine the surfaces into an innovative prismatic structure. Based on our design, the light collection elements capture the incident light with different angles, highly enhance the light collection efficiency. The normally incident light collection efficiency reaches 25.09% with AR coating and 19.35% without AR coating, the maximum efficiency enhanced ratio reaches 2.75 times compared to the conventional light collection elements.
