Far infrared (FIR) LED technology has gained significant attention in recent years due to its versatile applications across various industries. This article provides an in-depth introduction to the far infrared LED industry, covering its background, working principles, applications, and future prospects.

Background of Far Infrared LED Technology

Far infrared (FIR) refers to infrared radiation with a wavelength between 5 to 15 micrometers. FIR LED technology utilizes this range of wavelengths to produce far infrared light. The discovery of FIR in the 19th century laid the foundation for the development of FIR LED technology. Over the years, significant advancements have been made in the field, making FIR LED a popular choice for various applications.

Working Principles of Far Infrared LED

Far infrared LED technology works on the principle of semiconductor physics. When a forward bias voltage is applied to a semiconductor material, electrons and holes are generated, and they recombine to produce light. The wavelength of the emitted light depends on the energy gap of the semiconductor material. For FIR LED, the semiconductor material used has an energy gap suitable for emitting far infrared light.
