Far IR LED, or far infrared light-emitting diode, is a type of semiconductor device that emits infrared light with a wavelength longer than 750 nanometers. This technology has been widely used in various fields such as medical treatment, industrial heating, and agricultural applications. This article will provide an in-depth introduction to the far IR LED industry, covering its working principle, applications, market trends, and future development prospects.

Working Principle of Far IR LED

Far IR LED is a semiconductor device that converts electrical energy into far infrared light through the process of electron-hole recombination. The device is typically composed of a p-n junction, where electrons and holes recombine to release energy in the form of infrared radiation. The infrared radiation emitted by far IR LED has a wavelength range of 2 to 15 micrometers, which falls within the far infrared region of the electromagnetic spectrum.

Far IR LED is made of materials with specific energy band gaps, such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium antimonide (InSb). These materials can efficiently emit far infrared light when an electric current is applied. The wavelength of the emitted light can be tuned by adjusting the composition and structure of the semiconductor material.
