A light-emitting diode (LED) is a semiconductor device that emits light when an electric current passes through it. When a voltage is applied to the LED, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons, which creates light. This process of electron recombination produces the visible light that is emitted by the LED. LED lights are known for their energy efficiency, durability, and versatility in various applications.
