近年來，環保意識抬頭，太陽能源的運用更是綠能產業發展的重點目標。直接將陽光導入室內做為照明用，自然光照明系統並因此而誕生，但如何有效的擷取自然光，並有效的提高效率更是各學者長久以來努力的目標。此篇文章，我們提出一種新型結構的靜態式集光元件設計，該集光裝置結構由兩曲線型自由曲面所建立的透鏡組成，優良的透鏡設計並經由陣列方式堆疊排列及圓盤模組化後，可以將平行面光源壓縮成為點光源，並在圓盤圓心處將壓縮之高密度光線經由光纖導出作為照明。此外我們定義光學能量密度指標來計算太陽光線的集光效率值，此指標表示所蒐集到的陽光能量在集光器出口端的單位面積的流明值(1m/mm2)，並由此指標數值高低來評量集光器能量輸出之效率。在綠建築技術領域，如自然光照明系統均可應用本技術。陣列堆疊圓盤化設計的集光裝置能達到大面積鋪設，以及依實際需求決定其堆疊圈數、穩定堆疊集光效率等優點，搭配追日鏡技術更可應用於各式建築。可算是結合聚焦式與堆疊式集光器各自優點的新型設計。

In recent years, green energy has undergone a lot of development and has been used for many applications. Many research studies have focused on illumination with sunlight as a means of saving energy and creating healthy lighting. A lot of studies have focused on the use of sunlight to provide indoor lighting and save energy. To create a low-cost collector that can be easily installed on a large building, we have designed a static concentrator, to collect sunlight for indoor illumination. Prismatic elements are typical devices of natural light illumination system for redirecting and collecting daylight. Based on the principles of optics, this paper presents a new type mathematical matrix static solar concentrator. We collect sunlight using a plane round-shape concentrator, compressing parallel light beams and transmitting light beams through a channel module from the export outlet of the concentrator, and we transmit the high-density light via optic fiber cable for indoor illumination. In addition, we define an optical energy density factor to calculate the value of the light gathering efficiency of the sunlight on the concentrator. This indicator shows the illumination of collected sunlight on the export side of the concentrator per unit area (1m/mm2). Our team has evaluated the concentrator’s efficiency by the indicator. We have designed a high throughput plane solar concentrator using round-shape stacked structure. This system will provide a great number of benefits for the people who use it.
