Introduction to IR LED Diode

The IR LED diode, or infrared light-emitting diode, has emerged as a revolutionary technology in the fields of lighting and technology. As a key component in various applications, IR LED diodes have become indispensable in our daily lives. This article aims to provide an in-depth introduction to IR LED diodes, their working principles, applications, and the future prospects of this technology.

Working Principles of IR LED Diode

An IR LED diode is a semiconductor device that emits infrared light when an electric current passes through it. The working principle of an IR LED diode is based on the photoelectric effect. When the electric current flows through the diode, electrons and holes recombine in the depletion region, releasing energy in the form of photons. These photons have longer wavelengths than visible light, falling within the infrared spectrum. The key factors that affect the performance of an IR LED diode include the material composition, doping concentration, and temperature. The most commonly used materials for IR LED diodes are gallium arsenide (GaAs), gallium phosphide (GaP), and aluminum gallium arsenide (AlGaAs). By adjusting the doping concentration and temperature, the emission wavelength of the IR LED diode can be controlled within a specific range.
