Paper Abstract

There are so many existed static sunlight concentrators and SunLego® is the one of them. SunLego has the advantages of high concentrate efficiency and easy to produce. However, the concentrate efficiency will decrease dramatically of different sunlight incident azimuth angle. Current azimuth tolerance is from negative 30 degree to positive 30 degree. This issue will cause unstable lighting situation. We proposed an innovative static compound parabolic concentrator (CPC) and it will increase the concentrate efficiency largely. It composes of two main optical components; one is the innovative CPC on the up side to increase incident azimuth angle. The down side component is the prism structure to increase output fiber coupling efficiency.
