Infrared IR LED, or infrared emitting diode, is a type of semiconductor device that emits infrared radiation when an electric current is applied. It has become an indispensable part of various industries due to its numerous applications. This article will provide an in-depth introduction to the infrared IR LED industry, covering its history, technology, applications, and market trends.

History of Infrared IR LED

The history of infrared IR LED dates back to the early 20th century. In 1908, the German physicist Henry Ferdinand Heyl was the first to discover the infrared radiation emitted by a selenium crystal. However, it was not until the 1960s that the development of infrared IR LED began to gain momentum. In 1962, Nick Holonyak, an American physicist, successfully developed the first practical infrared IR LED, marking the beginning of the infrared LED industry.

Technology of Infrared IR LED

Infrared IR LED technology involves the use of semiconductor materials, such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs), to generate infrared radiation. The process involves the doping of semiconductor materials with impurities to create a PN junction. When an electric current is applied, electrons and holes recombine at the PN junction, emitting infrared radiation in the process.
