Revolutionizing Connectivity: The Cutting-Edge Role of Infrared LEDs in Modern Technology

With the rapid development of technology, infrared LED has become an essential component in various industries. As a type of light-emitting diode (LED), infrared LED emits light in the infrared spectrum, which is invisible to the human eye. This article aims to provide an in-depth introduction to the infrared LED industry, covering its history, applications, market trends, and future prospects.

History of Infrared LED

The concept of infrared light has been known for a long time, but it was not until the late 19th century that the first infrared LED was invented. In 1900, German physicist Heinrich Hertz discovered the phenomenon of infrared radiation, which led to the development of infrared technology. In 1962, Nick Holonyak, an American physicist, invented the first practical infrared LED at General Electric. Since then, infrared LED technology has been continuously improved and applied in various fields.
