Light Emitting Diode (LED)

A Light Emitting Diode (LED) is a device that emits light when electrical current flows through it. Unlike traditional bulbs, LEDs produce light through a process called electroluminescence, where energy is released as photons within a small semiconductor, usually made of materials like silicon or gallium arsenide. LEDs are energy-efficient, long-lasting, and come in various colors without the need for filters. They are commonly used in displays, indicators, and lighting solutions due to their durability and low power consumption.
