A light emitting diode (LED) is an electronic component that uses a semiconductor to emit light when current flows through it. Electrons in the semiconductor recombine with electron holes, thereby releasing energy in the form of photons.

An LED (light emitting diode) is a semiconductor device that emits infrared or visible light when charged with an electric current.
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.
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.
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.
This article is composed as a brief understanding guide to LED, which includes a brief introduction, the electrical symbol of LED, types, construction, characteristics, LED Drivers and many.
LEDs are classified as low power, mid power, or high power devices. Multiple LEDs must be combined to achieve the desired light output levels. This compact size enables flexible LED combinations and versatile lighting designs.
What Does LED Stand For? LED stands for Light Emitting Diode. It is a semiconductor device that emits light when electricity flows through it. Unlike traditional bulbs that use heat to create light, LEDs emit light directly from the movement of electrons.
In fact, the first two letters of LED stand for Light Emitting. A really nice thing about LEDs is that they are very simple. Unlike some chips that have dozens of pins with names and special uses, LEDs have only two wires. One wire is the anode (positive) and another is the cathode (negative).
