Far infrared LED, also known as far infrared light-emitting diode, is a type of semiconductor device that emits far infrared radiation. It has been widely used in various fields such as medical treatment, health care, agriculture, and industrial automation. This article will introduce the far infrared LED industry, including its working principle, application fields, market status, and future development trends.

Working Principle of Far Infrared LED

The far infrared LED is a semiconductor device that emits far infrared radiation through the excitation of electrons. When the forward voltage is applied to the diode, electrons and holes are generated in the P-N junction. These electrons and holes recombine in the active layer of the diode, releasing energy in the form of far infrared radiation. The wavelength of far infrared radiation is generally between 7.5μm and 15μm, which is in the infrared region of the electromagnetic spectrum.

Application Fields of Far Infrared LED

1. Medical Treatment and Health Care

Far infrared LED can be used in physical therapy, pain relief, and wound healing. The far infrared radiation can penetrate the skin and promote blood circulation, relieve muscle tension, and accelerate the healing of wounds. It is also used in the production of far infrared health care products, such as far infrared mats, far infrared blankets, and far infrared lamps.

2. Agriculture

Far infrared LED can be used in plant growth promotion, disease prevention, and pest control. The far infrared radiation can stimulate the photosynthesis of plants, improve the quality and yield of agricultural products, and reduce the occurrence of plant diseases and pests. It is also used in the production of far infrared agricultural equipment, such as far infrared growth lamps and far infrared pest control lamps.

3. Industrial Automation

Far infrared LED can be used in the detection and measurement of materials, as well as in the control and communication of industrial automation systems. The far infrared radiation can be used to detect the temperature, moisture, and thickness of materials, and can also be used for the transmission of signals in industrial automation systems.
