Far infrared light emitting diode (FIR LED) is a cutting-edge technology that has been gaining significant attention in various industries. This article aims to provide a comprehensive introduction to FIR LED, including its definition, working principle, applications, advantages, and future prospects.

Definition and Working Principle

Far infrared light emitting diode, also known as FIR LED, is a semiconductor device that emits far infrared radiation. It is widely used in various fields, such as medical treatment, agriculture, and environmental protection. FIR LED is based on the principle of semiconductor physics, where electrons and holes are recombined to emit photons with specific wavelengths.

Far infrared light has a wavelength range of 780nm to 1mm, which is longer than visible light but shorter than terahertz radiation. FIR LED can convert electrical energy into far infrared radiation efficiently, with a conversion efficiency of up to 90%. The working principle of FIR LED is similar to that of a traditional LED, but with a longer wavelength and higher output power.
