- Light-emitting diode - Wikipedia
LEDs have many advantages over incandescent light sources, including lower power consumption, a longer lifetime, improved physical robustness, smaller sizes, and faster switching
- LED | Definition, Light, Facts | Britannica
LED, in electronics, a semiconductor device that emits infrared or visible light when charged with an electric current LED displays began to be used for consumer electronic devices starting in 1968, when Hewlett-Packard (HP) introduced the first LED display
- Light Emitting Diode (LED): What is it How Does it Work?
LED Definition: A Light Emitting Diode (LED) is a semiconductor device that emits light when electric current flows through it Working Principle of LED: The working principle of LED involves applying a forward bias current, which causes electrons and holes to recombine at the junction, producing light
- How Light Emitting Diodes Work | HowStuffWorks
Light 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
- 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
- What Is an LED? - How-To Geek
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
- 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
- Light Emitting Diode (LED): Principle, Advantages, and Uses
