  • 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
  • Light Emitting Diode (LED): What is it How Does it Work?
    What is a Light Emitting Diode (LED)? A Light Emitting Diode (LED) is a special type of PN junction diode The light emitting diode is specially doped and made of a special type of semiconductor This diode can emit light when it is in the forward biased state
  • What Is an LED? - How-To Geek
    LEDs are more efficient than traditional light sources because they don't use heat to produce light Traditional light sources, such as light bulbs, produce light by heating a resistive tungsten wire until it glows white-hot
  • LED - Light Emitting Diode: Construction, Types Applications
    LED is a short form of Light Emitting Diode It is a type of diode that emits light when a current pass through it In other words, LED is a special type of diode that converts electrical energy into light energy It is a simple PN junction diode that radiates light in forward bias
  • LEDs: What Are They? (Definition, Types, and Uses)
    A LED or light-emitting diode is an electrical component that produces light when current passes through it LEDs are semiconductor devices, light is produced when the electrons combine with the material used as the semiconductor LEDs can come in a variety of different shapes, colours and sizes
