| Summary: | 碩士 === 國立臺灣科技大學 === 光電工程研究所 === 103 === Directly conveyance sunlight used to illuminate indoor is the most efficient way of utilizing solar energy.In this paper, we propose a lighting component with freeform microstructures that can be combined with the radial concentrator of NLIS (Natural Light Illumination System). Due to reversibility of light, the concentrator can be transformed into an emitter with this component. The component can recombine the luminous intensity distribution curve of the radial concentrator to a new one that recessed light has. It also can transform the sunlight from a point source to a surface source without lighting expander and the efficiency is 63.2%.
