Bookmark or Share- How Light Emitting Diodes Work | HowStuffWorksLight emitting diodes, commonly called LEDs, are real unsung heroes in the electronics world. They do many different jobs in all kinds of devices. They form numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances are turned on.
- LED | Definition, Lights, Types, & Facts | BritannicaLED, in electronics, a semiconductor device that emits infrared or visible light when charged with an electric current. Visible LEDs are used in many electronic devices as indicator lamps, in automobiles as rear-window and brake lights, and on billboards and signs as alphanumeric displays or even.
- 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 an LED? - How-To GeekA Diode That Emits Light. LED 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. The first material is typically a metal, such as aluminum or gold.
- 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.
