Definition of LED
LED known as Light Emitting Diode is a source of light, when a suitable voltage of electricity is getting contacted to the semiconductor. The visibility of LED ranged from low range to visible ultraviolet, infrared wavelength to high brightness. The material used in the semiconducting element. The PN junction area in LED is customised according to the application. LED are used in all categories of devices like digital clocks, remote controls, Television screen, traffic light and the list goes on. The lifespan of LED is more than the traditional incandescent bulbs. LED bulbs are used in the famous constructions like CN Tower, Singapore Flyer, Eiffel Tower, Tower Bridge and the list goes on.
