Introduction to Infrared IR LED Industry

What is an Infrared IR LED?

An infrared IR LED, short for Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current passes through it. It is widely used in various applications due to its compact size, low power consumption, and high efficiency. Unlike visible light, infrared light is not visible to the naked eye, making it suitable for applications that require covert or invisible signaling.

How Does an Infrared IR LED Work?

Infrared IR LEDs work on the principle of electroluminescence, where an electric current is applied to a semiconductor material, causing it to emit light. The semiconductor material used in infrared IR LEDs is typically made of gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs). When an electric current passes through the semiconductor material, it excites the electrons, causing them to recombine with holes, releasing energy in the form of infrared light.
