Advancements in Far Infrared Light Emitting Diode Technology: Innovations and Applications

Far infrared light emitting diode (FIR LED) is a type of semiconductor device that emits infrared light in the far infrared region of the electromagnetic spectrum. This technology has gained significant attention in recent years due to its numerous applications in various industries. This article aims to provide an in-depth introduction to the FIR LED industry, covering its working principle, applications, market trends, and future prospects.

Working Principle of FIR LED

The working principle of a FIR LED is based on the photoelectric effect, which occurs when electrons are excited and released from the valence band to the conduction band in a semiconductor material. In the case of FIR LEDs, the semiconductor material used is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). When an electric current is applied to the semiconductor material, electrons and holes are generated. As these electrons and holes recombine, they release energy in the form of infrared light.

The infrared light emitted by FIR LEDs has a wavelength range of 7.5 to 15 micrometers, which falls within the far infrared region of the electromagnetic spectrum. This makes FIR LEDs suitable for various applications that require long-wavelength infrared radiation.
