Abstract

Abstract—        We demonstrate an innovative application and investigative results of fiber optic day lighting systems as a means of bringing direct sunlight into a building while maintaining the controllability and ease of application usually reserved for electric lighting by collecting natural light and channeling it through optical fibers to luminaries within the space. In contrast to conventional methods of lighting as well as solar energy, this project focuses on reducing losses due to radiation, transmission and conversion to achieve increased efficiency and provide a profitable solution to the energy crisis the world is facing today.                                                              This project manifests the system performance which is accurately described by employing and analysis based on fiber and lens optics and interior illumination. Excellent efficiency is achieved which is only slightly reduced due to either  transmission losses, although negligible, or a cloudy day, by employing the concept of hybridizing solar source along with electrical source for optimum interior lighting. This is implemented by using high quality Fresnel lenses (for concentrating and collecting sunlight), optical fibers (for transmission) and luminaries (for lighting).                              Large scale commercial buildings such as textile showrooms, malls, hospitals, museums, schools, colleges are the major nerve centers of applicability of this project. For employing simple yet innovative principle, elementary mechanical concepts were executed with the sole purpose of curbing pollution, to dwindle green house effect and tackle energy crises. The high efficiency ingenious applicability achieved in this project brings it one step closer to commercialization.
