LED (Light Emitting Diode)

An LED, or Light Emitting Diode, is a semiconductor device that produces light when an electric current passes through it. Unlike traditional bulbs that use filaments or gases, LEDs are solid-state devices that convert electrical energy directly into visible light with high efficiency. They are durable, long-lasting, and consume less power, making them ideal for various applications like lighting, displays, and indicators. The color of the light depends on the materials used in the semiconductor, allowing LEDs to emit a wide range of colors without the need for filters.
