Led or Light emitting diode is a semiconductor device that emits or produces light when an electric current passes through it. Led lighting can be more versatile, efficient and long lasting as compare to compact fluorescent lightning. In our previous tutorials, we explain diodes, Zener diode, a p-n junction diode in detail. Here we are going to provide information regarding Led’s working, bulbs, construction and its types. This type of diode emits narrow bandwidth of visible light or invisible light at different colour wavelengths for remote control. It is preferable because it is small in area and to shape its radiation pattern Read More …
