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, Light, Facts | Britannica An LED (light-emitting diode) is a semiconductor device that emits infrared or visible light when charged with an electric current
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 (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

Light Emitting Diode (LED): What is it How Does it Work? What is a Light Emitting Diode (LED)? A Light Emitting Diode (LED) is a special type of PN junction diode The light emitting diode is specially doped and made of a special type of semiconductor This diode can emit light when it is in the forward biased state
Introduction to LEDs - Lighting Design Lab LED illumination is achieved when a semiconductor crystal is excited so that it directly produces visible light in a desired wavelength range (color) LED units are small, typically 5mm (T 1-3 4)
