Abstract

The daylight panel design we introduce increases inner wall illumination by 20% and improves daytime lighting efficiency. The three panel structures we simulated and manufactured are plain, triangular, and rhombic. Simulation and optical measurement results show that the rhombic structured panel uses daylight most efficiently. Our microstructured daylight panel increases building illumination and uniformity, reduces lighting-fixture glare, and saves energy, making it environment-friendly.
