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

Introduction to IR LED

The Infrared Light Emitting Diode (IR LED) is a type of 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, low power consumption, and long lifespan, the IR LED has revolutionized the way we perceive and utilize light.

How IR LED Works

The working principle of an IR LED is based on the semiconductor material's ability to emit light when an electric current passes through it. When a forward voltage is applied to the diode, electrons and holes recombine, releasing energy in the form of photons. These photons have longer wavelengths than visible light, which makes them invisible to the human eye. The IR LED emits light in the infrared spectrum, which ranges from 700 nm to 1 mm.
