Far IR LED, or far infrared light-emitting diode, is a type of semiconductor device that emits infrared light at a longer wavelength than traditional LEDs. This technology has gained significant attention in various industries due to its unique properties and applications. This article aims to provide an in-depth introduction to the far IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History of Far IR LED

The concept of infrared light was first discovered by the German physicist Heinrich Hertz in 1887. However, it was not until the 1960s that the first far IR LED was developed by the Japanese company Nippon Electric Co., Ltd. Since then, far IR LED technology has been rapidly developing and has been widely used in various fields.

Technology of Far IR LED

Far IR LED is a semiconductor device that emits infrared light at a longer wavelength than traditional LEDs. The core of the far IR LED is a semiconductor material, usually gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When an electric current passes through the semiconductor material, electrons and holes recombine, releasing energy in the form of infrared light.

The wavelength of the emitted infrared light is determined by the composition and structure of the semiconductor material. Generally, the longer the wavelength, the lower the energy level of the emitted light. Far IR LEDs can emit light with wavelengths ranging from 3 to 14 micrometers.
