Light Emitting Diodes (LED)

A Light Emitting Diode (LED) is a semiconductor device that emits light when an electric current passes through it. Inside, electrons recombine with electron holes, releasing energy in the form of photons, which produce visible light. LEDs are energy-efficient, durable, and have a long lifespan compared to traditional bulbs. They come in various colors and are used for everything from indicator lights to bright illumination and display screens. Their solid-state design means they are more resistant to shock and vibration, making them a reliable choice for diverse lighting applications.
