light-emitting diodes (LEDs)

Light-emitting diodes (LEDs) are semiconductor devices that produce light when an electric current passes through them. They work by allowing electrons to recombine with holes in the material, releasing energy as photons, which is visible light. LEDs are energy-efficient, long-lasting, and available in various colors. Unlike traditional bulbs, they do not have filaments and generate less heat. Commonly used in displays, indicators, and lighting, LEDs are a modern, eco-friendly lighting technology that provides bright, reliable illumination with minimal energy consumption.
