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.
