LED

An LED (Light Emitting Diode) is a type of energy-efficient light source that produces illumination when electrical current flows through it. Unlike traditional bulbs, LEDs use semiconductors to emit light directly, resulting in lower energy consumption, longer lifespan, and less heat. They are used in various applications, from screens and indicators to general lighting, offering bright, focused illumination with minimal environmental impact. LEDs operate on the principle of electroluminescence, where electrical energy is converted into light at the atomic level within the semiconductor material.
