Light-emitting diode - Wikipedia
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, 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.
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.
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): 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.
