Abstract

High power Light Emitting Diodes (HPLEDS) are adopted for lighting purpose, making them the fastest growing light source worldwide. This paper discusses HPLED lamp of various shapes with different lux levels and different heat sink requirements when used for indoor lighting. To provide constant current to LED, a driver circuit is designed using a dc to dc converter and a microcontroller. The input of the converter is a 24V battery which is charged from a photo voltaic panel. To verify the design of the driver circuit, the circuit was simulated in Proteus software. Besides simulation, laboratory prototype of 8W LED lamp of different shapes are constructed, tested and the results are presented here. .
