- 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
- Light Emitting Diode (LED): Principle, Advantages, and Uses
A light-emitting diode (LED) is a small electronic device that emits light when an electric current flows through it LED works by passing electricity through a semiconductor, which releases energy in the form of light This process makes an LED highly efficient, durable, and versatile, finding its applications in everyday devices such as smartphones, TVs, and home lighting systems
- Learn About LED Lighting - ENERGY STAR
LED lighting differs from incandescent and fluorescent in several ways When designed well, LED lighting is more efficient, versatile, and lasts longer LEDs are “directional” light sources, which means they emit light in a specific direction, unlike incandescent and CFL, which emit light and heat in all directions
- 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
