Introduction to Infrared Emitter Tube LED

Background and Definition

Infrared emitter tube LED, also known as infrared LED, is a type of semiconductor light-emitting diode that emits infrared light. It is widely used in various fields such as communication, security, medical, and industrial applications. As the name suggests, the main feature of infrared emitter tube LED is its ability to emit infrared light, which is invisible to the human eye. This makes it an ideal choice for applications where visible light is not desired or required. The infrared emitter tube LED works on the principle of semiconductor physics. When a forward voltage is applied to the diode, electrons and holes recombine at the junction, releasing energy in the form of photons. The energy of these photons determines the wavelength of the emitted light. In the case of infrared emitter tube LED, the emitted light falls within the infrared spectrum, which ranges from 700 nm to 1 mm.

Types of Infrared Emitter Tube LED

There are several types of infrared emitter tube LED, each with its own unique characteristics and applications. The most common types include: 1. AlGaAs Infrared Emitter Tube LED: This type of infrared LED is made of aluminum gallium arsenide (AlGaAs) semiconductor material. It has a longer wavelength and higher power output compared to other types of infrared emitter tube LED. AlGaAs infrared emitter tube LED is commonly used in applications such as remote control, communication, and security systems. 2. InGaAs Infrared Emitter Tube LED: Infrared emitter tube LED made of indium gallium arsenide (InGaAs) semiconductor material has a shorter wavelength and lower power output compared to AlGaAs infrared emitter tube LED. It is often used in applications such as fiber optic communication, optical sensors, and medical imaging. 3. GaAs Infrared Emitter Tube LED: This type of infrared LED is made of gallium arsenide (GaAs) semiconductor material. It has a shorter wavelength and higher power output than InGaAs infrared emitter tube LED. GaAs infrared emitter tube LED is commonly used in applications such as night vision, thermal imaging, and laser communication.
