Far infrared light emitting diode (FIR LED) is a type of semiconductor device that emits infrared light in the far infrared spectrum. As a cutting-edge technology, FIR LED has been widely used in various fields such as medical treatment, agriculture, and environmental protection. This article will introduce the industry of FIR LED, including its working principle, application fields, market status, and future development trends.

Working Principle of FIR LED

The working principle of FIR LED is based on the photoelectric effect of semiconductor materials. When a forward voltage is applied to the LED, electrons and holes are generated in the semiconductor material, and they recombine in the active region. During the recombination process, a part of the energy is released in the form of infrared light. The wavelength of FIR LED is between 780nm and 15μm, which is in the far infrared spectrum.

Application Fields of FIR LED

1. Medical Treatment FIR LED has been used in medical treatment for many years. It can promote blood circulation, relieve muscle fatigue, and improve the body's immune function. FIR LED therapy is commonly used in the treatment of musculoskeletal diseases, chronic pain, and postoperative rehabilitation. 2. Agriculture FIR LED can promote plant growth, improve crop yield, and enhance the quality of agricultural products. FIR LED lighting can provide plants with a more suitable light environment, which can effectively improve the photosynthesis rate and promote the growth of plants. 3. Environmental Protection FIR LED has a wide range of applications in environmental protection. It can be used for the detection and treatment of air and water pollution, as well as the sterilization and disinfection of the environment. FIR LED technology can also be used for the development of new energy-saving and environmentally friendly products.
