The LED stands for lighting emitting diode. The LED is an electromagnetic light source. In more detail the LED is a semiconductor diode that when is switched on (forward bias), electrons are able to recombine with free holes and energy is transmitted as light. This phenomenon is called electroluminescence and the semi-conductor’s energy gap determines the color of the light.
