LEDs, or Light Emitting Diodes, are semiconductor devices that emit light when an electric current passes through them. They are known for their energy efficiency and long lifespan compared to traditional incandescent bulbs. LEDs are widely used in various applications, from household lighting to electronic displays and automotive lighting. The technology behind LEDs allows for a range of colors and brightness levels, making them versatile for different settings. Their low power consumption and durability make them an environmentally friendly choice, contributing to reduced energy costs and less waste in landfills.
