Infrared IR LED: A Revolution in Lighting Technology

In recent years, the infrared IR LED has emerged as a revolutionary technology in the lighting industry. As a type of light-emitting diode (LED), the infrared IR LED offers numerous advantages over traditional lighting solutions, making it a popular choice for various applications. This article aims to provide an in-depth introduction to the infrared IR LED, covering its working principle, advantages, applications, and future prospects.

Working Principle of Infrared IR LED

The infrared IR LED is a semiconductor device that emits infrared light when an electric current passes through it. The working principle of an infrared IR LED is based on the photoelectric effect. When a forward voltage is applied to the LED, electrons and holes are injected into the active region, where they recombine and release energy in the form of photons. These photons have a longer wavelength than visible light, falling within the infrared spectrum. The key components of an infrared IR LED include the semiconductor material, a p-n junction, and a metal contact. The semiconductor material is typically made of gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs). The p-n junction creates a potential barrier that controls the flow of electrons and holes, while the metal contact provides a path for the electric current.
