Far IR LED, short for far infrared light-emitting diode, is a type of semiconductor device that emits infrared light with a wavelength longer than 780nm. It has been widely used in various fields such as medical treatment, industrial heating, agricultural cultivation, and security monitoring. In this article, we will introduce the far IR LED industry, including its basic principles, applications, market status, and future development trends.

Basic Principles of Far IR LED

Far IR LED is a semiconductor device that uses the principle of semiconductor physics to emit infrared light. The basic structure of a far IR LED includes a p-n junction, which is composed of a p-type semiconductor and an n-type semiconductor. When the p-n junction is forward biased, electrons and holes are injected into the depletion region, and recombination occurs. During the recombination process, the energy of the electrons is released in the form of infrared light.
