A simulation study of passive sunlight collection and emission for solar lighting

Abstract

This research involves a simple and high concentration simulation design for a passive solar lighting system. This system incorporates the technology and optical design that are required for the collection and emission of sunlight for solar lighting. Several pieces of Plano-convex lens are placed in a specific geometric arrangement, so that without a solar tracking system, parallel light emitted by the sun at different times can be collected. The light can then be focused via lenses and internally transmitted through optical fibers and ultimately be transmitted to the emission element. This system is expected to be used as a reference for sufficient lighting for indoor rooms and toilets in a building whether in the morning or afternoon on a sunny day.
