Far infrared LED, also known as far infrared light-emitting diode, is a type of semiconductor device that emits far infrared radiation. It has become increasingly popular in various industries due to its unique properties and wide range of applications. This article aims to provide an in-depth introduction to the far infrared LED industry, covering its history, technology, applications, and future prospects.

History of Far Infrared LED

The concept of far infrared LED was first proposed in the 1960s. However, it was not until the 1980s that significant progress was made in the development of far infrared LED technology. The first commercial far infrared LED was produced in the early 1990s. Since then, the industry has witnessed rapid growth, with numerous applications emerging in various fields.

Technology of Far Infrared LED

Far infrared LED technology is based on the principle of semiconductor physics. When a forward bias is applied to a semiconductor material, electrons and holes are generated, and the recombination of these carriers results in the emission of photons. The wavelength of the emitted photons depends on the energy bandgap of the semiconductor material. For far infrared LEDs, the semiconductor material typically used is gallium arsenide (GaAs) or its alloys.

Far infrared LED devices consist of several key components, including the semiconductor material, a p-n junction, a metal contact, and an encapsulation material. The semiconductor material is doped with impurities to create a p-n junction, which is responsible for the generation of electrons and holes. The metal contact provides an electrical connection to the p-n junction, while the encapsulation material protects the device from external environmental factors.
