IR LED light, or Infrared Light Emitting Diode, has become an integral part of various industries due to its unique properties and applications. This article aims to provide a comprehensive introduction to the IR LED light industry, covering its history, technology, applications, market trends, and future prospects.

History of IR LED Light Technology

The concept of the LED was first introduced by Oleg Vladimirovich Losev in 1927, but it was not until the 1960s that the first practical LED was developed by Nick Holonyak Jr. at General Electric. The early LEDs were primarily red and yellow, but as technology advanced, researchers began to explore the potential of infrared (IR) LEDs. The first IR LEDs were developed in the 1970s, and since then, the technology has seen significant advancements, making it a crucial component in numerous applications.

Technology Behind IR LED Lights

IR LEDs are semiconductor devices that emit infrared light when an electric current is applied. They consist of a p-n junction, where the p-type and n-type materials are doped with impurities to create a forward-biased diode. When current flows through the junction, electrons recombine with holes, releasing energy in the form of photons. The wavelength of the emitted light depends on the composition of the semiconductor material. The key to the functionality of an IR LED lies in its semiconductor material. Different materials emit light at different wavelengths, with IR LEDs typically emitting light in the range of 700 to 3000 nanometers. Common materials used in IR LEDs include gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs).
