Introduction to Infrared Transmitting Tube LED

What is an Infrared Transmitting Tube LED?

An infrared transmitting 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 widely used in various applications, such as remote controls, communication systems, and security systems. In this article, we will explore the features, applications, and future trends of infrared transmitting tube LEDs.

Working Principle of Infrared Transmitting Tube LED

The working principle of an infrared transmitting tube LED is based on the photoelectric effect. When a forward voltage is applied to the diode, electrons and holes are generated in the semiconductor material. As these electrons and holes recombine, they release energy in the form of photons. In the case of an infrared transmitting tube LED, these photons are in the infrared spectrum, which is not visible to the human eye. The key components of an infrared transmitting tube LED include the semiconductor material, a p-n junction, and a lens. The semiconductor material is typically made of gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs). The p-n junction is formed by doping the semiconductor material with impurities to create an electric field that separates the electrons and holes. The lens is used to focus the emitted infrared radiation into a narrow beam.
