LED full form: LED stands for light emitting diode. A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. LEDs have allowed video displays, new text and sensors to be developed.
In the simplest terms, a Light Emitting Diodes (LED) is a semiconductor device that emits light when an electric current is passed through it. Light is generated when the particles (known as electrons and holes) are combined together within the semiconductor material.
Following are the main features of light emitting diode (LED):
