Far infrared LED, or far infrared light-emitting diode, is a type of semiconductor device that emits infrared radiation in the far infrared spectrum. This technology has been widely used in various fields such as medical treatment, agriculture, and industrial applications due to its unique physical and biological effects. In this article, we will introduce the far infrared LED industry, including its development history, working principle, application fields, and market prospects.

Development History of Far Infrared LED

The development of far infrared LED technology can be traced back to the early 20th century. In 1905, the German physicist Heinrich Hertz discovered the existence of infrared radiation. Later, in the 1920s, the British physicist William Henry Brewster conducted research on the transmission and reflection of infrared radiation. In the 1950s, the invention of the semiconductor diode laid the foundation for the development of far infrared LED technology. In the 1970s, the first far infrared LED was successfully developed, marking the birth of this industry.

Working Principle of Far Infrared LED

Far infrared LED is a semiconductor device that emits infrared radiation in the far infrared spectrum. It consists of a semiconductor material with a p-n junction. When the forward bias voltage is applied to the p-n junction, electrons and holes are generated, which recombine and emit photons with energy corresponding to the bandgap of the semiconductor material. These photons fall within the far infrared spectrum, which is characterized by a wavelength range of 7.7μm to 1000μm.

Application Fields of Far Infrared LED

Far infrared LED technology has been widely used in various fields due to its unique physical and biological effects.

Medical Treatment: Far infrared LED can be used for physical therapy, pain relief, and wound healing. The far infrared radiation can penetrate the skin and promote blood circulation, thereby improving the body's immune function and accelerating the healing of wounds.

Agriculture: Far infrared LED can be used to promote plant growth and improve crop yield. The far infrared radiation can enhance the photosynthesis of plants, improve the quality of fruits and vegetables, and reduce the incidence of diseases.

Industrial Applications: Far infrared LED can be used for heat treatment, drying, and non-destructive testing. The far infrared radiation can effectively heat the material, improve the material's performance, and detect the internal structure of the material without damaging it.
