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 a wavelength longer than that of visible light but shorter than that of microwaves. Infrared LEDs are widely used in various applications, including remote controls, security systems, and medical devices.

How Does an Infrared Emitter Tube LED Work?

An infrared emitter tube LED operates on the principle of the PN junction. When a forward voltage is applied to the diode, electrons and holes are injected into the PN junction. As these charge carriers recombine, they release energy in the form of photons. In the case of an infrared LED, the photons have a longer wavelength and lower energy than visible light photons, resulting in the emission of infrared radiation. The key components of an infrared emitter tube LED include the semiconductor material, the PN junction, and the encapsulation. 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 an excess of electrons (n-type) and holes (p-type). The encapsulation is used to protect the LED and to enhance its performance.
