- 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, releasing energy in the form of photons
- LED lamp - Wikipedia
LED lamps require an electronic LED circuit to operate from mains power lines, and losses from this circuit means that the efficiency of the lamp is lower than the efficiency of the LED chips it uses The driver circuit may require special features to be compatible with lamp dimmers intended for use on incandescent lamps
- 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
- 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 Definition Meaning - Merriam-Webster
