由於全球能源耗竭以及溫室效應所帶來的氣候變遷，各國開始重視節能減碳與能源開發的議題。目前再生能源的應用也正快速的發展中，開始追求綠色生活環境以降低對環境的破壞。綠建築順應而生，目前建築產業中努力推廣綠能建築，但對於綠色照明的部分，卻只透過天窗、天井來實踐採光與照明的效果，但安裝天窗、天井反失去了隱私與部分區域的照明，唯有透過自然光導光技術，才能將自然光引導至屋內的任何區域，並且保障隱私與提供健康的照明。
自然導光系統也是一種不需電力的被動式導光系統，裝置於建築物上將自然光引導至室內作照明，如果能在建築上設計並裝置自然導光的照明，不僅能夠提供來自陽光的維生素帶來健康與治療憂鬱症與皮膚病、取代天窗保護隱私、輔助燈具達成照明節能效果、透過色溫改變提升使用者的舒適度。最後推廣至既有建築物上，解決綠建築照明市場的問題，為綠色建築帶來全新的發展。
本論文將論述國內外導光系統的分析與介紹，各式集光器可應用於何種場合，剖析各導光系統之結構與自然導光系統相似之處，說明自然導光系統其創新關鍵技術與設計重點，並說明PSSDL自然導光系統的設計方法，且將各式的集光技術加以分類與分析，提供任何想涉入自然導光領域的人都能夠瞭解其設計目標與方法。
本文最後將主要四種不同方式的集光器做比較，將高輸出靜態式圓盤堆疊結構集光器、靜態稜鏡光斧、靜態式雙層可堆疊集光器、稜鏡陣列集光器做比較，建立此四種集光器模型，對其X軸向、Z軸向進行分析，分析在相同條件下軸向的效率與容忍度，最後在透過中央氣象局的數據分析，設定太陽仰角與方位角，分析其四季對於集光器的影響與四季的平均效率，最後提出目前設計的集光系統所面臨的問題，並提出自然導光系統未來的設計上，該如何解決容忍角不足與集光效率問題，使下一代的集光系統能夠擴大集光角度與集光效率。

Regrading to the energy-saving and carbon dioxide reduction, the green energy has been gaining popularity in recent years. For saving energy and healthy lighting, there are many researches to focus on sunlight system without opto-electronic conversion.
This research will discuss natural light illumination system at home and abroad. Analyze the different structures of natural light illumination system. And describe the design method of PSSDL natural light illumination system, and classify and analyze all kinds of light collecting technology, and provide anyone who wants to be involved in natural light illumination system to know the design method.
In this paper, the main four different ways to compare the collector, the high output static disk stack structure collector, static prism light ax, static double stackable collector, prism array collector The X-axis and Z-axis analysis were carried out to analyze the efficiency and tolerance of the axial under the same conditions. Finally, through the analysis of the data of the Central Weather Bureau. And the azimuth angle, analyzes the influence of its four seasons on the collector and the average efficiency of the four seasons. Finally, the paper puts forward the problems of the current system, and puts forward the future design of the natural light guide system. Set the light efficiency problem, so that the next generation of light collection system can expand the light collection angle and set light efficiency.
