What is led definition?

LED (Light Emitting Diode) refers to a semiconductor device that emits light when an electric current passes through it. LEDs are widely used in various electronic devices such as TVs, computers, mobile phones, traffic signals, automotive lighting, and more. LEDs are energy-efficient, have a longer life span, and come in various colors and brightness levels. LEDs can be used for decorative purposes as well as functional lighting purposes. They emit less heat than traditional incandescent bulbs and are environmentally friendly due to their low energy consumption and lack of toxic materials. LEDs are becoming more and more widespread because of the decreasing cost of production and their many advantages over other lighting technologies.
