Optical fibre based smart illumination system

Abstract

Electricity crisis is a very common fact in today's world. Conventional lighting system requires huge electricity consumption. So some smart systems are used for illumination purposes which can maximize the utilization of available natural resources. One of the smart options which can replace the conventional lighting system using electricity is the use of natural resources for illumination where sunlight can't reach in the day time. The sunlight harvesting system is that smart lighting system which can save electricity in subways, offices, malls, etc where daytime lighting is very much required. This smart system consists of optical fibers, focusing lens assembly, photo sensor and microcontroller. After transmission through the optical fiber the ambient light is focused on the lens assembly for illumination in all the places where the sunlight cannot be accessed directly. By using the Photo sensor assembly the proper position of the sun can be tracked which maximizes the light input into the optical fiber system. This assembly is also required to measure the intensity of sunlight to avoid the unfavorable lighting condition (cloudy days, etc.). According to the measured value the electric light intensity will be controlled automatically which results less energy consumption.
