Diode IR, or Infrared Diode, is a crucial component in the field of infrared technology. As a type of semiconductor diode, it plays a vital role in converting infrared light into electrical signals, which is widely used in various applications such as thermal imaging, remote controls, and optical communication. This article will provide an in-depth introduction to the diode IR industry, covering its history, working principle, applications, and future development trends.

History of Diode IR

The history of diode IR can be traced back to the early 20th century when infrared technology began to emerge. In 1900, German physicist Heinrich Hertz discovered the existence of infrared radiation, which laid the foundation for the development of infrared technology. In the 1930s, the first infrared diode was developed by an American scientist named John Bardeen. Since then, the diode IR industry has undergone rapid development, with numerous advancements and innovations in technology.

Working Principle of Diode IR

The working principle of diode IR is based on the photoelectric effect. When infrared light is incident on the p-n junction of a semiconductor material, it can generate electron-hole pairs. The electron-hole pairs will then move to the respective sides of the junction, resulting in an electrical current. The intensity of the current is proportional to the intensity of the incident infrared light. Diode IR can be divided into two types: photodiode and phototransistor. The photodiode is a direct conversion device, while the phototransistor is an indirect conversion device with a higher sensitivity.
