Revolutionizing Home Automation: The Role of IR LED Technology

Introducing the IR LED: A Game-Changer in the Lighting Industry

Introduction to IR LED

The infrared light-emitting diode (IR LED) is a semiconductor device that emits infrared light when an electric current is applied. It has become an integral part of various industries, including consumer electronics, automotive, medical, and industrial applications. With its compact size, high efficiency, and long lifespan, the IR LED has revolutionized the way we perceive and utilize light.

How IR LED Works

An IR LED is composed of a semiconductor material, typically gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs). When an electric current is applied, the electrons and holes in the semiconductor material recombine, releasing energy in the form of infrared light. The emitted light has a wavelength range of 700 to 3000 nanometers, which is beyond the visible spectrum.
