近年來由於能源危機,人們開始尋找具乾淨、安全、永續性的替代能源來取代傳統能源,其中太陽能為取之不盡用之不竭的能源,因此提出將陽光導入室內做為白天時照明的日光照明系統逐漸成為熱門的研究議題,本實驗室所提出之自然光照明系統為日光照明系統中之一類。在現今市面上大多數的日光照明系統發展中主要運作模式皆以收集日光並將所收集到的所有光線傳導至室內環境來做為照明應用,然而我們知道室內建築物中依據使用目的不同有著不同的空間,而各種不同空間有著不同的照明需求,因此現行日光照明系統將所有收集到的光線導引進入各種不同室內空間的運作方式,並非一個最佳能源利用方式。所以為了更有效地利用日光照明系統所收集到的光能,我們利用多曲率反射鏡結構去設計一具有可調整分光比功能之分光器安裝於本實驗室自然光照明系統,藉由可調分光器我們可以根據不同空間照明需求分別以93.01%、93.09%、93.34%的效率自由地調整1:1、2:1、1:3分光比。
Due to the energy crisis, many scientists have focused on the research of the alternative energy.One of the alternative energy is the solar energy, it is inexhaustible, clean and safe. Therefore, the daylighting systems which directly guiding the sunlight into indoor environmentfor illuminationbecomes one of the popular research topic.
Traditionally, indoor environment were illuminated with the total collected sunlight in the daylighting systems. However, there are different illumination requirements for different environments. Therefore, current operation way of the daylighting systemsis an inefficient way of energy using.In order to use the energy efficiently, we design an optical beam splitter with tunable power split ratio based on a multi-curvature reflector. With our design, we are able to tune the 1:1, 2:1, and 3:1 power splitratio according to different illumination needs with 93.01%, 93.09%, and 93.34% efficiency respectively.
