What is LED?

A light-emitting diode (LED) is an electronic light source. Discovered in the early 20th century, LEDs were introduced as practical components in 1962. The technical jargon necessary to explain LED technology entails words and phrases including anodes, cathodes, diodes and photons, silicon carbide and gallium arsenide and electron holes. Oh, and of course, the cat's whisker detector. But we won't delve into all of that. We'll keep it simple, while still illuminating.

Early LED devices emitted low-intensity red light. Remember the blinking light on your old telephone answering machine? That was an LED. Modern LEDs are brighter and available across a number of wavelengths, including visible, ultraviolet and infrared. The bottom line is this: LEDs are a better way to bring light to life.
