This article aims to provide an in-depth introduction to the diode IR industry, covering its history, technology, applications, and future prospects.

History of Diode IR Technology

The concept of diode IR technology dates back to the early 20th century. In 1908, Henry Joseph Round, an English physicist, discovered that certain materials could emit infrared radiation when an electric current was passed through them. This discovery laid the foundation for the development of diode IR technology. Over the years, significant advancements have been made in the manufacturing processes and performance of diode IR devices.

How Diode IR Works

Diode IR devices operate based on the principle of the photoelectric effect. When an electric current is applied to a diode IR, electrons are excited and move to a higher energy level. As these electrons return to their original state, they release energy in the form of infrared radiation. The wavelength of the emitted radiation depends on the material and structure of the diode IR.
