Light-emitting diode is an electric component that emits light when connected to direct current. It works on electroluminescent principle and can emit light in visible specter as well as in infrared and ultraviolet. They have characteristically low energy consumption, small size, longer lifetime and faster switching than incandescence lamps and because of that, they have a wide palette of applicability.
"In 1907, British experimenter in Marconi labs Henry Joseph Round noticed for the first time that when a potential of 10volts is applied to carborundum (silicon carbide) crystal, it emits yellowish light. However, first to investigate it and to propose a working theory was Oleg Vladimirovich Losev from Russia. In 1927, Oleg published a paper “Luminous carborundum detector and detection effect and oscillations with crystals“.
White Light Emitting Diodes
For decades no progress was made for different reasons. Rubin Braunstein that worked at Radio Corporation of America, reported in 1955 that some simple diodes emit infrared light when connected to a current. In 1961, Gary Pittman and Bob Biard from Texas Instruments found that that gallium-arsenide diode emits infrared light every time it is connected to current"
Hahaha Yes they did
