Introduction

The infrared emitter tube, also known as an infrared diode, is a semiconductor device that emits infrared radiation when an electric current passes through it. It is widely used in various applications, such as remote controls, night vision devices, and thermal imaging cameras. This article aims to provide an in-depth introduction to the infrared emitter tube industry, covering its history, working principle, types, applications, and future prospects.

History of Infrared Emitter Tube

The concept of infrared emitter tube dates back to the early 20th century. In 1908, a Russian physicist named Pyotr Lebedev discovered that when a semiconductor was subjected to an electric current, it emitted infrared radiation. This discovery laid the foundation for the development of infrared emitter tubes. Over the years, with the advancement of semiconductor technology, the performance and reliability of infrared emitter tubes have been significantly improved.

Working Principle of Infrared Emitter Tube

The working principle of an infrared emitter tube is based on the photoelectric effect. When an electric current passes through the semiconductor material, electrons are excited and move to a higher energy level. As these electrons return to their original energy level, they release energy in the form of infrared radiation. The wavelength of the emitted infrared radiation depends on the type of semiconductor material used.
