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. Unlike visible light, infrared light is not visible to the human eye. It is used in a wide range of applications, from consumer electronics to industrial automation. The infrared IR LED industry has seen significant growth over the years, driven by advancements in technology and increasing demand for its applications.
How Does an Infrared IR LED Work?
An infrared IR LED works on the principle of semiconductor physics. When an electric current is applied to the diode, electrons and holes recombine at the junction, releasing energy in the form of photons. These photons have longer wavelengths than visible light, falling within the infrared spectrum. The color of the emitted light depends on the material used in the diode. For example, a diode made of gallium arsenide emits infrared light at a shorter wavelength, while a diode made of indium gallium arsenide emits longer-wavelength infrared light.
