Far infrared (FIR) LED, also known as far infrared light-emitting diode, is a type of semiconductor device that emits far infrared radiation. With the rapid development of technology and the increasing demand for health and environmental protection, FIR LED has become an important part of the infrared lighting industry. This article will introduce the basic concepts, application fields, and market prospects of FIR LED in the industry.

Basic Concepts of FIR LED

FIR LED is a semiconductor device that can emit far infrared radiation. It has the advantages of low power consumption, long service life, and environmental protection. The far infrared radiation emitted by FIR LED has a wavelength of 780nm to 15μm, which is far beyond the visible light range. FIR LED can be used in various fields, such as medical treatment, health care, and industrial production.

Working Principle of FIR LED

The working principle of FIR LED is based on the photoelectric effect of semiconductor materials. When the forward voltage is applied to the p-n junction of the semiconductor material, the electrons and holes are injected into the conduction band, and the recombination of electrons and holes in the conduction band emits far infrared radiation. The far infrared radiation emitted by FIR LED has a wide wavelength range, strong penetration, and can be absorbed by the human body, which has a good effect on the human body's health.

Application Fields of FIR LED

1. Medical Treatment: FIR LED can be used in physical therapy, wound healing, and rehabilitation. The far infrared radiation emitted by FIR LED can promote blood circulation, reduce inflammation, and relieve pain, which has a good effect on the treatment of various diseases.

2. Health Care: FIR LED can be used in health care products, such as FIR lamps, FIR masks, and FIR mats. FIR LED can help people relax, improve sleep quality, and promote health and beauty.

3. Industrial Production: FIR LED can be used in industrial drying, heat treatment, and non-destructive testing. The far infrared radiation emitted by FIR LED has a high thermal effect, which can improve the quality of industrial products and reduce energy consumption.

4. Agriculture: FIR LED can be used in agricultural production, such as seed germination, plant growth, and disease prevention. FIR LED can promote plant growth, improve crop yield, and reduce pesticide use.
