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.
The 1st LED was invented in 1920 by a Russian radio technician called Oleg Vladimirovich Losev. Losev found that diodes used radio receivers emitted light when current passed through them. LEDs are part of our daily life for quite some time now. Mobile phone screens have been lit up by LEDs as well as the on/off switches of electrical appliances.
