A light-emitting diode is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.

When was the light-emitting diode invented?

In 1962, when he was 33, the scientist Nick Holonyak, Jr., created the first practical visible light-emitting diode.

Who invented light?

In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light.

Who is the father of LED lighting?

Who invented the red LED?

The First Light-Emitting Diode with Practical Use

Experimenting with the use of the semiconductor Gallium Arsenide that had started during the 1950s subsequently led to the development of the very first LED with practical use. In 1962, Nick Holonyak, Jr. invented the first LED that could produce visible red light.
