This article aims to provide an in-depth introduction to the infrared emitter tube, exploring its working principles, types, applications, and future prospects in the industry.

Working Principles of Infrared Emitter Tube

An infrared emitter tube, also known as an infrared diode, is a semiconductor device that emits infrared radiation when an electric current passes through it. The working principle of an infrared emitter tube is based on the photoelectric effect. When electrons are excited by an external electric field, they move from the valence band to the conduction band, releasing energy in the form of infrared radiation. The infrared emitter tube consists of a semiconductor material, typically a combination of gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to emit infrared radiation efficiently. The emitted infrared light has a wavelength ranging from 0.75 to 3.0 micrometers, which is beyond the visible spectrum of human eyes.
