Infrared LED light, also known as infrared diode, has become an integral part of various industries due to its ability to emit infrared radiation. This article provides a comprehensive introduction to the infrared LED light industry, covering its history, applications, technology, market trends, and future prospects.

History of Infrared LED Light

The concept of infrared light has been known for centuries, but it was not until the late 19th century that the first infrared diode was developed. In 1906, a German physicist named Ferdinand Braun discovered that certain materials could emit infrared radiation when an electric current was applied to them. This discovery laid the foundation for the development of infrared LED lights. Over the years, advancements in semiconductor technology have led to the miniaturization and increased efficiency of infrared LEDs.

Technology of Infrared LED Light

Infrared LED lights are made of semiconductor materials, such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium nitride (InGaN). These materials have a direct bandgap, which allows them to emit infrared radiation when an electric current passes through them. The process of creating an infrared LED involves growing a thin layer of semiconductor material on a substrate, then doping it to create a p-n junction. When an electric current is applied, electrons and holes recombine at the junction, emitting infrared photons.
