Why was LED invented?
In 1962, Nick Holonyak, Jr. invented the first LED that could produce visible red light. He invented these red diodes while he was employed with General Electric. … Using Gallium Phosphide as the substrate increased the efficiency of the lights and brighter red LEDs came into being.
Are LED lights bad for your eyes?
The short answer to this is no, they won’t hurt your eyes. This concern comes from the LED bulb’s use of blue light. … It can only become a problem for people who have existing eye conditions. LEDs use the same amount of blue light that our smartphones, computers, and tablets use.
How did Nick Holonyak invent the LED?
At a time when other researchers focused on infrared light, Holonyak invented a method to synthesize gallium arsenide phosphide (GaAsP) crystals, which exhibited wavelengths in the visible spectrum. Using this “tunable” alloy, Holonyak crafted the first practical LED in 1962 (the red LED).
