Far infrared (FIR) LED, also known as long-wavelength infrared LED, is a type of semiconductor light-emitting diode that emits light at wavelengths longer than visible light. This article aims to provide an in-depth introduction to the industry of FIR LED, covering its basic principles, applications, market trends, and future prospects.

Basic Principles of FIR LED

FIR LED is a semiconductor device that can emit light in the far infrared spectrum. It is made up of a p-n junction, where electrons and holes recombine and emit photons. The key to generating far infrared light lies in the semiconductor material used in the LED. Commonly used materials include gallium arsenide (GaAs), gallium antimonide (GaSb), and indium antimonide (InSb). These materials have energy band gaps that allow them to emit photons at far infrared wavelengths.

Applications of FIR LED

FIR LED has a wide range of applications due to its unique properties. Here are some of the main applications:

• Therapeutic Devices: FIR LED is widely used in therapeutic devices, such as infrared saunas, heat therapy machines, and pain relief devices. The far infrared light can penetrate the skin and promote blood circulation, muscle relaxation, and cell repair.
• Healthcare: FIR LED is used in various medical applications, such as tissue healing, wound treatment, and cancer therapy. The light can stimulate the body's natural healing processes and improve the effectiveness of certain treatments.
• Industrial Applications: FIR LED is used in industrial applications, such as heat treatment, non-destructive testing, and material processing. The long-wavelength infrared light can effectively heat materials and detect defects without damaging them.
• Agriculture: FIR LED is used in agriculture for plant growth promotion and disease control. The light can accelerate plant growth, improve crop yield, and protect plants from pests and diseases.
• Environmental Protection: FIR LED is used in environmental protection applications, such as waste treatment and air purification. The long-wavelength infrared light can break down harmful substances and improve air quality.
