Far infrared LED (Far IR LED) technology has gained significant attention in recent years due to its wide range of applications and benefits. 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 concept of far infrared LED technology dates back to the early 20th century when infrared radiation was first discovered. However, it was not until the late 20th century that significant advancements were made in the development of far infrared LED devices. The first far infrared LED was developed in the 1970s, and since then, the technology has evolved rapidly, leading to the development of various types of far infrared LED devices.

Technology of Far Infrared LED

Far infrared LED technology involves the use of semiconductor materials to generate far infrared radiation. The process begins with the selection of suitable semiconductor materials, such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have the ability to emit far infrared radiation when excited by an electrical current.

Once the semiconductor materials are selected, they are then processed into a p-n junction structure. When an electrical current is applied to the p-n junction, electrons and holes are generated, which recombine and emit far infrared radiation. The wavelength of the emitted radiation can be tuned by adjusting the composition and structure of the semiconductor materials.
