在面臨溫室效應全球暖化、能源短缺與環境惡化下，綠能產業如太陽能因此蓬勃的發展，其中【自然光照明系統】為太陽能之一重要應用，主要概念為透過集光器直接將太陽光導入室內做為照明用途。
在現有的【自然光照明系統】中，其稜鏡式集光器有高聚光比的特性，但其設計上使得入射光能量經過太多的折射與介面損耗，導致其效率不佳。為解決此問題，我們提出一種新型結構的靜態式稜鏡集光器，以稜鏡為基礎，將稜鏡以陣列的方式設計，並透過司乃爾定律計算，使入射光在通過稜鏡集光器時只會經過至多一次的偏折與介面損耗，藉此可大幅提高其效率。而模組化的設計上，利用反向錯位的設計，使其模組可在一個維度延伸排列，減少集光面積的浪費。
我們收集了台灣台北四季時間從a.m. 7:00到p.m.5:00之太陽資訊，模擬了此集光器在各個時間點所收集的能量。在垂直入射的平行光源設定，單一模組集光面積下效率可達57%。在夏季在一整日可提供313流明的能量。

Nowadays, energy-saving and carbon dioxide reduction become more and more important due to global warming. Utilization of solar energy, which is considered one of the most important renewable energy sources, not only reduces consumption of fossil fuel but also slows down the pace of global warming. For Illumination, our team has developed a technique called the “Natural Light Illumination” that sunlight is guided directly by our system instead of using solar cell. Our system can guide sunlight to the interior, but the efficiency of light collecting module is low. To solve this problem, we have proposed a new light collecting module based on prism structure with high efficiency. We used optical simulation tools to design and simulate the efficiency of the module. The efficiency of the module is 57%, which is higher than the original concentrator (11%).
