In the fall of 1961, while working at Texas Instruments Inc., James R. Biard and Gary E. Pittman found that gallium arsenide (GaAs) emitted infrared light when electric current was applied. On Aug. 8th, 1962, Biard and Pittman filed a patent based on their findings titled "Semiconductor Radiant Diode" (U.S. Patent US3293513). After establishing the priority of their work based on engineering notebooks predating submissions from G.E. Labs, RCA Research Labs, IBM Research Labs, Bell Labs, and Lincoln Labs at MIT, the U.S. patent office issued the two inventors the first patent for the infrared (IR) light-emitting diode, the first modern LED. After filing the patent, Texas Instruments immediately began a project to manufacture infrared diodes. They announced the first commercial LED product (the SNX-100) in October of 1962.

"Nick Holonyak, 75, invented the LED (light emitting diode) in the 1960s."
Who invented the first LED light bulb?
Thomas Edison invented light because he made light so why not bulbs
Where was the led light bulb invented?

What is meant by CREE LED Torches?
A CREE LED torch is like a normal battery powered torch, only using some newer features. The most important is the LED (Light Emitting Diode) invented by a American company named CREE. CREE LED's are mostly known for their efficiency. They are normally around 5 times more efficient then a Halogen light of the same spec.
What is LED Forward Voltage?
The forward voltage of an LED is the voltage that must be applied across the leads of an LED, anode to cathode, in order for the LED to function and turn on.
Who invented the led sign?
