Far infrared light emitting diode (FIR LED) is a cutting-edge technology that has gained significant attention in recent years. As an important component in the field of infrared technology, FIR LED is widely used in various applications, such as medical treatment, industrial automation, and consumer electronics. This article aims to provide an in-depth introduction to the FIR LED industry, covering its working principle, application fields, market trends, and future development prospects.

Working Principle of Far Infrared Light Emitting Diode

FIR LED is a semiconductor device that emits far infrared light when an electric current is applied. It is composed of a p-n junction, where the p-type semiconductor material and the n-type semiconductor material are combined. When an electric current passes through the p-n junction, electrons and holes are generated. As the electrons and holes recombine, they release energy in the form of far infrared light. The working principle of FIR LED can be summarized as follows: 1. Electric current injection: An electric current is applied to the p-n junction, causing electrons and holes to be injected into the active layer. 2. Recombination process: The electrons and holes recombine in the active layer, releasing energy in the form of far infrared light. 3. Light emission: The emitted far infrared light is transmitted through the lens or the optical fiber to the target application.
