Introduction to Infrared Emitter Tube LED

What is an Infrared Emitter Tube LED?

An infrared emitter tube LED, also known as an infrared LED, is a type of light-emitting diode that emits infrared radiation. Unlike visible light, infrared radiation is not visible to the human eye. It is a form of electromagnetic radiation with wavelengths longer than those of visible light but shorter than those of microwaves. Infrared emitter tube LEDs are widely used in various applications, including remote controls, security systems, medical devices, and industrial automation.

How Does an Infrared Emitter Tube LED Work?

An infrared emitter tube LED operates based on the principle of the PN junction. When an electric current is applied to the PN junction, electrons and holes recombine, releasing energy in the form of photons. In the case of an infrared emitter tube LED, these photons have wavelengths within the infrared spectrum. The process of emitting infrared radiation is known as photoluminescence. The key components of an infrared emitter tube LED include the semiconductor material, the PN junction, and the package. The semiconductor material is typically made of gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs). The PN junction is formed by doping the semiconductor material with impurities to create a region with excess electrons (n-type) and a region with excess holes (p-type). The package is designed to protect the LED and facilitate the emission of infrared radiation.
