- Light-emitting diode - Wikipedia
In electrical engineering, 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, thereby releasing energy in the form of photons
- LED Definition Meaning - Merriam-Webster
The meaning of LED is past tense and past participle of lead When to Use Lead or Led
- 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
- 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 (Light-emitting diode) explained - Soldered Electronics
The first question that might pop into your mind is, what is exactly an LED? A regular diode is a semiconductor device that works as a one-way switch for electrical current It allows current in only one direction and will stop it from flowing in the other An LED works the same way
- LED Lighting - Department of Energy
The light-emitting diode (LED) is today's most energy-efficient and rapidly developing lighting technology Quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other types of lighting
- 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
- What is LED ( Light Emitting Diodes ) | LED Lighting Supply
LED dates back to the early 1900s when a British physicist discovered silicon carbide crystals could produce light when electric currents were touched In 1962, GE scientist Nick Holonyak developed the first visible light LED diode
