Detailed explanation-1: -A Light Emitting Diode (LED) is a semiconductor device, which can emit light when an electric current passes through it. To do this, holes from p-type semiconductors recombine with electrons from n-type semiconductors to produce light.
Detailed explanation-2: -The light emitting diode (LED) is a heavily doped p-n junction with forward bias. Because it is an important light source used in optical communication and is based on the principle of conversion of biasing electricity into light.
Detailed explanation-3: -Light emitting diodes, commonly called LEDs, are real unsung heroes in the electronics world. They do many different jobs in all kinds of devices.
Detailed explanation-4: -Working Principle: A light-emitting diode is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.
