PROJECT DESCRIPTION

The main aim of this project is to develop an automatic-emergency-light circuit which is able to turn ON LED lights automatically (powered by rechargeable batteries), whenever power failure occurs during  night time. 

In this circuit, we use a PNP transistor as a switch that gets activated on sensining missing mains supply. The advantage of this emergency light is that we use this light in a room with a LED light source being powered from batteries with high energy conversion efficiency. Re- chargeable batteries used for this circuit include  NiCd or NIMh or LI-Ion type for getting high usable life.
