LED stands for “Light Emitting Diode.” A light emitting diode (LED) is a type of semiconductor device that emits light when an electrical current is passed through it. LEDs are widely used in a variety of applications, including electronic displays, lighting, and signaling. They are known for their high energy efficiency and long lifespan, and they are often used as an alternative to traditional light bulbs. LEDs are made up of a semiconductor material that is doped with impurities to create a p-n junction. When an electrical current is applied to the LED, electrons are able to flow through the material and recombine with holes, releasing energy in the form of light. LEDs are available in a range of colors and sizes, and they are commonly used in a variety of applications, including automotive lighting, home lighting, and outdoor lighting.
