Background and Overview

Infrared emitter tube LED, also known as infrared LED, is a type of light-emitting diode that emits infrared radiation. It has become an essential component in various applications, such as remote controls, surveillance systems, and medical devices. The infrared emitter tube LED has gained significant attention in the industry due to its high efficiency, long lifespan, and compact size. This article aims to provide an in-depth introduction to the infrared emitter tube LED, covering its working principle, applications, advantages, and market trends.

Working Principle of Infrared Emitter Tube LED

The infrared emitter tube LED works on the principle of electroluminescence. When a forward voltage is applied across the diode, electrons and holes recombine at the p-n junction, releasing energy in the form of photons. In the case of an infrared emitter tube LED, these photons have a longer wavelength and lower energy compared to visible light, resulting in the emission of infrared radiation. The key components of an infrared emitter tube LED include the semiconductor material, the p-n junction, and the encapsulation. The semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), determines the wavelength of the emitted infrared radiation. The p-n junction is formed by doping the semiconductor material with impurities to create a region where electrons and holes can recombine. The encapsulation, usually made of glass or plastic, protects the diode from external factors and enhances its radiation efficiency.
