- 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 lamp - Wikipedia
An LED lamp or LED light[1] is an electric light that produces light using light-emitting diodes (LEDs)
- Light-emitting diode physics - Wikipedia
Light-emitting diodes (LEDs) produce light (or infrared radiation) by the recombination of electrons and electron holes in a semiconductor, a process called "electroluminescence" The wavelength of the light produced depends on the energy band gap of the semiconductors used
- Light-emitting diode - Simple English Wikipedia, the free encyclopedia
A light-emitting diode (LED) is a semiconductor device that produces light from electricity LEDs last a long time and do not break easily (compared to incandescent lightbulbs) They can produce many different colors They are efficient - most of the energy turns into light, not heat [1]
- 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
- LED lamp - Wikiwand
An LED lamp or LED light is an electric light that produces light using light-emitting diodes (LEDs) LED lamps are significantly more energy-efficient than equ
- LED Lights - How it Works - History - Edison Tech Center
LEDs create light by electroluminescence in a semiconductor material Electroluminescence is the phenomenon of a material emitting light when electric current or an electric field is passed through it - this happens when electrons are sent through the material and fill electron holes
- LED lighting - Wikipedia
After nearly 25 years, Wikipedia is still the internet we were promised—created by people, not by machines It's not perfect, but it's not here to push a point of view It's owned by a nonprofit, not a giant technology company or a billionaire
- History of the LED - Wikipedia
In 1927, Russian inventor Oleg Losev created the first LED The first practical LED was developed in 1961 by researchers at Texas Instruments The 1970s saw the first commercial LEDs
- Light-emitting diode - Wiki. . . - University of Utah
From Wikipedia, the free encyclopedia A light-emitting diode (LED) (pronounced ˌɛl iː ˈdiː [1]) is a semiconductor light source LEDs are used as indicator lamps in many devices, and are increasingly used for lighting
