- Light-emitting diode - Wikipedia
A light-emitting diode (LED) is an electronic component that uses a semiconductor to emit light when current flows through it Electrons in the semiconductor recombine with electron holes, thereby releasing energy in the form of photons
- LED | Definition, Light, Facts | Britannica
An LED (light-emitting diode) is a semiconductor device that emits infrared or visible light when charged with an electric current
- Learn About LED Lighting - ENERGY STAR
LED stands for light emitting diode LED lighting products produce light up to 90% more efficiently than incandescent light bulbs How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light
