Abstract

The purpose of Natural Light Illumination System (NLIS) is to provide people a comfort and health indoor illumination by directing sunlight into indoor from the light collector. The NLIS is composed of three sub-systems, light collection, light transmission and light emission. Although we can use the high efficiency light pipe to transmit the light in the NLIS. However, once the light transmission path of the light pipe encounters the reflection corner, the efficiency and the candela distribution of the light will decrease and change. Therefore, we design a tunable light distributor installed between the light transmit and light emit sub-system in this paper.
