Who invented the LED?

LEDs, or Light-Emitting Diodes, are a semiconductor source of light, which emit photons when electrons recombine with electron holes within the device. Ranging from most basic electronic equipment all the way to expensive cars and advanced lighting devices, LEDs can be found in a multitude of colors and configurations.

But who invented LEDs?

LEDs are a brainchild of Nick Holonyak (John Bardeen‘s first Ph.D student), who is often referred to as the father of the light emitting diode. While working as a consultant for General Electric’s laboratory, Nick Holonyak invented the first useful and visible LED in 1962. Althoug
