Introduction

Infrared Emitter Tube: A Brief Overview

The infrared emitter tube, also known as an infrared LED, 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, security systems, medical devices, and industrial automation. This article aims to provide an in-depth introduction to the infrared emitter tube industry, covering its history, technology, applications, market trends, and future prospects.

History of Infrared Emitter Tube

The development of the infrared emitter tube dates back to the early 20th century. In 1900, the German physicist Heinrich Hertz discovered that infrared radiation could be generated by heating a wire filament. However, it was not until the 1960s that the first practical infrared emitter tube was developed by the American company RCA. Since then, the technology has undergone significant advancements, leading to the wide range of applications we see today.

Technology of Infrared Emitter Tube

The infrared emitter tube is a semiconductor device that consists of a p-n junction. When an electric current passes through the junction, electrons and holes recombine, releasing energy in the form of infrared radiation. The key parameters of an infrared emitter tube include its wavelength, intensity, and emission angle. The wavelength of an infrared emitter tube is determined by the material used in its semiconductor layer. Common materials include gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). The intensity of the emitted radiation is influenced by the current passing through the tube and the temperature of the semiconductor material. The emission angle refers to the spread of the emitted radiation and is determined by the design of the tube's housing.
