This article aims to provide an in-depth introduction to the far infrared LED industry, covering its history, technology, applications, market trends, and future prospects.

History of Far Infrared LED Technology

The development of far infrared LED technology can be traced back to the early 20th century when scientists began exploring the properties of infrared radiation. However, it was not until the late 1950s that the first far infrared LED was developed. Since then, significant advancements have been made in the efficiency, lifespan, and cost-effectiveness of these devices. The technology has evolved from simple diodes to complex systems that can be integrated into various applications.

Technology of Far Infrared LED

Far infrared LEDs operate on the principle of semiconductor physics. They consist of a semiconductor material that emits light when an electric current is applied. The key to creating a far infrared LED is selecting the appropriate semiconductor material that can efficiently emit light in the far infrared spectrum. Common materials used include gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). The structure of a far infrared LED typically includes a p-n junction, where the p-type and n-type regions are doped with different impurities to create a potential barrier. When an electric current is applied, electrons and holes recombine at the junction, releasing energy in the form of infrared light. The wavelength of the emitted light is determined by the energy bandgap of the semiconductor material.
