Light Emitting Diodes (LEDs) are semiconductor light source. These lights are often used in the lamps as a replacement of incandescent light sources. LEDs have longer life, require less power, small in size and are robust in nature. The advantages of LED over incandescent light lamps such as high efficiency, longer life span, high reliability, high brightness levels and condensed size are driving the LED market as a whole. Hence, LEDs are being used in various applications such as aviation lighting, camera flashes, traffic signals, headlights, etc., market players are adopting product launch as their key developmental strategy. Recently, GE Lightings launched a new bulb that can be connected to a smart-phone very economically. The key players in the global market are Philips Electronics, Digital Lumens, Inc., Cree Inc., Osram Licht AG, Dialight plc, Zumtobel AG, GE Lightings, Toshiba Corp. and Cooper Industries plc.
