Who invented the LED light bulb?
Nick Holonyak, Jr.
The next year, in 1962, Nick Holonyak, Jr. (the “Father of the Light-Emitting Diode”) invented the first LED that produced visible, red light while working at General Electric. Throughout the 1960s, researchers and engineers continued experimenting with semiconductors with the goal of producing more efficient LEDs.
When was the light bulb invented?
January 1879
By January 1879, at his laboratory in Menlo Park, New Jersey, Edison had built his first high resistance, incandescent electric light. It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting.
