LED is semiconductor Technology that emits light at the junction of oppositely charged materials when voltage forces electron movement. Led based lighting systems are devices consisting of many LEDs chips embedded on the LED fixtures base and fitted with rectifier circuit that provides regulated current output at the low voltage that makes them to be operated on AC Circuit because LEDs requires DC to operate.The whole PCB circuit board is fitted inside a plastic enclosure along with the metallic cap and Smokey reflector.
Conventional lighting systems represent mainly incandescent light bulbs and compact fluorescent lights (CFLs).LED lighting
system provides advantages over conventional lighting systems in terms of better energy efficiency, better energy costs, longer lifetime, less temp. Sensivity, higher light output. This leads them to be better Lighting substitute and good market prospect. Therefore the market prospect for LED based Lighting system is good and booming.
