What is LED?

An LED (Light Emitting Diode) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. LEDs are used in a wide range of applications, including lighting, displays, and indicators, due to their energy efficiency, long lifespan, and small size.
