What is define led?

LED stands for "light-emitting diode". It is a type of semiconductor component that emits light when an electric current passes through it. LEDs consume less energy and have longer lifespans than traditional incandescent bulbs. They are commonly used in electronic devices, automotive lighting, household lighting, and in streetlights. LED technology has also been used in the development of smartphone screens, computer monitors, and TVs. They come in various shapes, sizes, and colors, including white, red, green, and blue. LED lights are also available in dimmable and smart versions, and are generally considered more eco-friendly due to their low energy consumption and reduced environmental impact.
