Revolutionizing Heat Therapy: The Advancements and Benefits of Far Infrared LED Technology

Far infrared LED, or far infrared light-emitting diode, is a type of semiconductor device that emits infrared radiation at wavelengths longer than those of visible light. These LEDs are widely used in various applications, including medical diagnostics, thermal imaging, and consumer electronics. This article provides an in-depth introduction to the far infrared LED industry, covering its technology, applications, market trends, and future prospects.

Introduction to Far Infrared LED Technology

Far infrared LEDs are based on the principle of semiconductor physics, where electrons are excited and recombine to emit photons. The key to producing far infrared radiation lies in the material composition of the LED. Typically, these LEDs are made from compounds such as gallium arsenide (GaAs), indium gallium arsenide (InGaAs), and aluminum gallium arsenide (AlGaAs). These materials have band gaps that allow them to emit infrared radiation at longer wavelengths, typically between 7.5 to 30 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 electric field necessary for the emission of infrared radiation. The quality of the epitaxial layer and the design of the LED structure significantly affect the performance of the device, including its emission wavelength, intensity, and efficiency.
