Far infrared light emitting diode (FIR LED) is a type of semiconductor device that emits far infrared radiation. As a cutting-edge technology, FIR LED has been widely used in various fields such as medical treatment, environmental protection, and industrial automation. This article will introduce the development, application, and future prospects of FIR LED technology.

Development of Far Infrared Light Emitting Diode Technology

The development of FIR LED technology can be traced back to the early 20th century. In 1917, Albert Einstein proposed the theory of stimulated emission, which laid the foundation for the development of semiconductor devices. In the 1950s, the first FIR LED was successfully developed, and it was mainly used in military and aerospace fields. With the continuous development of semiconductor technology, FIR LED has been gradually applied to more fields. The development of FIR LED technology can be divided into three stages: 1. The initial stage (1950s-1970s): The development of FIR LED was mainly based on the research of infrared semiconductor materials. During this period, the research focus was on the development of high-quality infrared semiconductor materials and the improvement of the performance of FIR LED devices. 2. The rapid development stage (1980s-1990s): With the rapid development of semiconductor technology, the performance of FIR LED devices was significantly improved. At this stage, the research focus shifted to the optimization of the structure of FIR LED devices and the improvement of their emission characteristics. 3. The maturity stage (2000s-present): With the continuous optimization of FIR LED devices, their performance has reached a relatively high level. At this stage, the research focus is mainly on the application of FIR LED technology in various fields and the exploration of new applications.
