Infrared emitter tube LED, also known as infrared emitting diode, is a semiconductor device that emits infrared light when electric current passes through it. It is widely used in various fields such as consumer electronics, automotive, medical equipment, and industrial automation. This article will provide an in-depth introduction to the infrared emitter tube LED industry, covering its history, working principle, applications, market trends, and future development.

History of Infrared Emitter Tube LED

The infrared emitter tube LED has a long history, dating back to the early 20th century. In 1900, the British physicist Sir William Henry Bragg proposed the concept of infrared radiation, which laid the foundation for the development of infrared emitter tube LED. In the 1960s, the infrared emitting diode was first developed by Japanese scientists, and its application gradually expanded to various fields.

Working Principle of Infrared Emitter Tube LED

The working principle of the infrared emitter tube LED is based on the photoelectric effect. When the semiconductor material is excited by an electric current, electrons and holes are generated in the conduction band and valence band, respectively. As the electrons and holes recombine, they release energy in the form of photons, which are emitted as infrared light. The key factors affecting the performance of the infrared emitter tube LED include the semiconductor material, structure, and drive mode. Currently, the most commonly used semiconductor materials are gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium nitride (InGaN). The structure of the infrared emitter tube LED mainly includes the epitaxial layer, the p-type layer, the n-type layer, and the encapsulation layer. The drive mode can be divided into DC drive and AC drive, with DC drive being more commonly used.
