隨著綠色能源的環保意識的抬頭。人們開始注重健康和能源問題，因此，如何有效的運用綠色能源與節能減碳，已成為我們最重要的課題。現在有關於自然光和其應用有很多研究，可以提供大眾健康與舒適的照明。而如何在最大限度的開發，並利用自然光成為現今照明研究領域最關切的議題，太陽能儼然成為最具有廣泛應用潛力的能源選項。
而為了完善利用太陽能並減少能量的損耗，我們的團隊已耗費數年致力於以日光創造健康的照明環境之研究，並設計出一系列的相關產品，稱之為自然光照明系統(Natural Light Illumination System, NLIS)。自然光照明系統以自然光導入室內直接做為照明使用的方式取代傳統以太陽能電池進行光轉電的做法，此舉可以省去光電轉換的過程所產生的能量耗損。
而在自然光照明系統的集光元件與傳光元件往往因效率或是傳輸距離導致效果不如預期，於是我們設計了一集光模組並具有傳光的功能。此模組內的集光單元由兩片反射鏡與一個多光路設計的稜形結構所組成。而我們的集光模組，由五個集光單元所組成。此集光模組可傳輸168米以上的距離、最佳傳輸效率是54.15％以上、最佳集光效率為39.26%。

With the rise of environmental awareness of green energy. People began to focus on health and energy issues, therefore, how effective the use of green energy and carbon reduction has become our most important issue. There are about natural light and its applications are many studies that can provide public health and comfortable lighting. And how to maximize the development and use of natural light to become today's lighting research topics of greatest concern, solar energy has become the most widely used option potential.
In order to improve the utilization of solar energy and reduce energy loss, our team has spent several years working on creating healthy daylight lighting environment and designed a series of related products, known as natural lighting system (Natural Light Illumination System , NLIS). Natural lighting system to natural light into the interior lighting used directly as a way to replace the traditional light switch electric solar cells approach the move can save the energy generated by the photoelectric conversion process of wear and tear.
In the set of optical elements and natural light transmission optical element is often due to the efficiency of the system or cause the transmission distance effect as expected, so we designed a set of optical transmission module and has the function of light. Set within this module optical unit consists of two mirrors and optical design of a multi-prismatic structure components. And we set light module consists of five sets consisting of a light unit. This set of optical modules can be transmitted as far as 168 meters away, the best transmission efficiency is 54.15%, the best light collection efficiency of 39.26%.Keywords: Solar concentrator with transmission function, Daylight illumination, daylight illumination system.
