Far infrared (FIR) LED, short for far infrared light-emitting diode, is a type of semiconductor device that emits infrared light with a wavelength longer than 780nm. It has been widely used in various fields such as medical treatment, health care, agriculture, and environmental protection due to its excellent biocompatibility and low energy consumption. This article will introduce the basic concept, working principle, applications, and market prospects of FIR LED in detail.

Basic Concept of FIR LED

FIR LED is a kind of semiconductor device that emits infrared light. It is composed of a semiconductor material with a band gap larger than 1.2eV, which can produce infrared light with a wavelength longer than 780nm. FIR LED has excellent biocompatibility and low energy consumption, so it is widely used in various fields.

Working Principle of FIR LED

The working principle of FIR LED is based on the principle of semiconductor p-n junction. When the p-n junction is forward biased, the electrons and holes in the semiconductor material are excited and collide, releasing energy in the form of infrared light. The longer the wavelength of the infrared light, the lower the energy consumption and the higher the biocompatibility.

Applications of FIR LED

1. Medical Treatment: FIR LED can promote blood circulation, relieve muscle fatigue, and improve the metabolism of human body. It is widely used in physiotherapy, massage equipment, and beauty equipment.

2. Health Care: FIR LED can stimulate the skin's self-healing ability, promote cell growth, and enhance the immune function of the human body. It is used in health care products such as infrared saunas, infrared heating pads, and infrared neck braces.

3. Agriculture: FIR LED can provide plants with a light source with a suitable wavelength, which can promote plant growth, improve the quality of agricultural products, and increase yields. It is used in plant cultivation, horticulture, and aquaculture.

4. Environmental Protection: FIR LED has low energy consumption and long service life, which can reduce energy consumption and environmental pollution. It is used in energy-saving lamps, solar lamps, and other green lighting products.

Market Prospects of FIR LED

With the continuous development of science and technology, the demand for FIR LED in various fields is increasing. According to the market research report, the global FIR LED market is expected to maintain a rapid growth rate in the next few years. The main reasons are as follows:
