Bookmark or Share- Light-emitting diode - WikipediaA 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.
- What is LED? - Definition, Working, Properties, Uses, Advantages - BYJU'SA light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. Based on the semiconductor material used and the amount of doping, an LED will emit a coloured light at a particular spectral wavelength when forward biased.
- LCD vs. LED: What's the Difference Between the Displays?LED stands for light-emitting diode. Unlike LCDs, LEDs utilize an array of semiconductor light-emitting diodes to produce light. Each diode emits its own light when a current passes through it, eliminating the need for a separate light source, such as CCFLs. LEDs offer several advantages over traditional LCDs.
- Learn About LED Lighting - ENERGY STARLED 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.
- What Is an LED? - How-To GeekLED stands for "Light-Emitting Diode." The word "diode" is a key component here, because a diode is a semiconductor that only allows electricity to flow in one direction. To make an LED, manufacturers take two materials and place them in close proximity.
