Far infrared LED, or far infrared light-emitting diode, is a specialized type of LED that emits light in the far infrared (FIR) spectrum, which ranges from 780 nm to 3000 nm. This technology has gained significant attention in various industries due to its unique properties and applications. In this article, we will delve into the world of far infrared LED, exploring its technology, applications, market trends, and future prospects.

Introduction to Far Infrared LED Technology

Far infrared LEDs are semiconductor devices that emit light in the far infrared region of the electromagnetic spectrum. They are typically made from materials such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have bandgap energies that correspond to the far infrared wavelengths, allowing them to emit light in this range.

The structure of a far infrared LED is similar to that of a conventional LED, consisting of a p-n junction. When an electric current is applied, electrons and holes recombine at the junction, releasing energy in the form of photons. The photons emitted have wavelengths within the far infrared range, making them suitable for applications that require heat or thermal radiation.
