Far infrared LED, or far infrared light-emitting diode, is a type of semiconductor device that emits infrared radiation at wavelengths longer than visible light. These LEDs are widely used in various applications due to their ability to provide heat and facilitate various therapeutic processes. This article delves into the industry of far infrared LEDs, exploring their technology, applications, market trends, and future prospects.

Technology of Far Infrared LEDs

Far infrared LEDs are based on semiconductor materials that have a bandgap suitable for emitting infrared radiation at the far infrared region of the electromagnetic spectrum. Common semiconductor materials used in far infrared LEDs include gallium arsenide (GaAs), gallium phosphide (GaP), and indium antimonide (InSb). These materials have a bandgap that allows them to emit infrared radiation at wavelengths ranging from 7 to 15 micrometers.

The manufacturing process of far infrared LEDs involves epitaxial growth, where a thin layer of semiconductor material is deposited onto a substrate. This layer is then doped with impurities to create a p-n junction, which generates the electrical current that excites the electrons and causes them to recombine, emitting infrared radiation in the process. The efficiency of far infrared LEDs is typically measured by their light output, which is determined by the design of the LED structure and the quality of the materials used.
