Far infrared LED, also known as far infrared light-emitting diode, is a type of semiconductor device that emits far infrared light. It has become increasingly popular in various industries due to its unique properties and wide range of applications. This article aims to provide an in-depth introduction to the far infrared LED industry, covering its history, technology, applications, and future prospects.

History of Far Infrared LED

The concept of far infrared LED dates back to the early 20th century. In 1900, German physicist Heinrich Hertz discovered the existence of infrared radiation. However, it was not until the 1950s that the first far infrared LED was developed by Japanese scientist Shuji Nakamura. Since then, the technology has undergone significant advancements, and far infrared LED has found its way into various fields.

Technology of Far Infrared LED

Far infrared LED is a semiconductor device that emits far infrared light when an electric current is applied. The device typically consists of a p-n junction, where electrons and holes recombine, releasing energy in the form of far infrared light. The key to producing far infrared LED lies in the selection of suitable semiconductor materials and the design of the device structure.

Common semiconductor materials used in far infrared LED include gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have specific band gaps that determine the wavelength of the emitted light. By adjusting the composition and structure of the semiconductor materials, it is possible to achieve the desired far infrared emission characteristics.
