LED stands for Light Emitting Diode. It is a semiconductor device that emits light when an electric current passes through it. LEDs are widely used in various applications due to their energy efficiency, long lifespan, and versatility.

In lighting, LEDs have become the preferred choice over traditional incandescent and fluorescent bulbs because they consume less energy and produce less heat while providing bright illumination. LED lighting is used in homes, offices, streetlights, automotive lighting, and more.

LEDs are also commonly used in electronic devices as indicator lights, display panels, and backlighting for screens, such as TVs, computer monitors, and smartphones. Their compact size and low power consumption make them ideal for portable devices.

Moreover, LEDs are employed in automotive applications, like headlights and taillights, due to their durability and high visibility.

In recent years, advancements in LED technology have led to the development of RGB LEDs, which can produce a wide range of colors, making them popular in decorative lighting, gaming peripherals, and entertainment systems.
