Light Emitting Diode

The Light Emitting Diode was developed by Professor Nick Holonyak Jr. in 1962 during his employment at General Electric.  Following up on prior research on gallium arsenide Holoyak began to develop the L.E.D. He hypothesized that the gallium arsenide would produce visible light when the right amount of electrical current is applied to the leads. This modern marvel has led to major innovations since Professor Holoyak’s demonstration in 1962. The L.E.D can now be found the majority of our technological device. Over the past few years as the technology has, become more affordable we see the L.E.D popping up throughout our daily lives.  Ranging from Cellphones, TV, Lights, computers, and in automobiles.
