UTILIZATION OF DIRECT SOLAR RADIATION FOR INDOOR LIGHTING

This study focuses on the development of an optical fibre based indoor lighting system through utilization of direct solar radiation. Using the approach of renewable energy which is the sun, this paper discusses the concept of the manifestation of solar radiation for indoor lighting. The study proposes a design of this system and also highlights the fabrication besides testing process. The design of the daylighting system is focused on. Parabolic design for the solar collector is discussed. A design of the overall working system is presented using AutoCAD software. Alternative approach using light refraction method is also focused on. The working principle of the optical fibre based indoor lighting system through light refraction method is highlighted. The efficiency of the system is also included in this study. Efficiency will be evaluated through monitoring and testing procedures. Tabulation of gathered data will also be displayed. An analysis on the optical fiber based day lighting system in Universiti Teknologi PETRONAS is also executed.
