Design and Implementation of a Power Failure Home Lighting System Using LED Arrays

Abstract

This paper is on the design and implementation of a power failure lighting system using light emitting diodes (LED) arrays. The aim of this work is to design and implement a lighting system that can provide low power at home when there is power failure. The lighting system was achieved by the design of the: Power Supply Unit, Charging Unit, Change Over Switch, Battery Level Indicator, LED arrays.The power failure home lighting system was designed and implemented in a three bedroom flat apartment in Benin City when there was power failure. The total lighting points in the house consume a total power of 160 watts which was very low compared to energy saving (i.e. CFL) lamp (312 watts) and incandescent bulbs (480 to 740 watts). The designed power failure home lighting system performed satisfactorily.
