Introduction to Infrared Transmitting Tube LED

What is an Infrared Transmitting Tube LED?

An infrared transmitting tube LED, also known as an infrared emitting diode, is a type of light-emitting diode (LED) that emits infrared radiation. Unlike visible light, infrared radiation is not visible to the human eye, but it is commonly used in various applications such as remote controls, communication systems, and security systems. The infrared transmitting tube LED is designed to emit infrared light with high efficiency and low power consumption, making it a popular choice for a wide range of applications.

Working Principle of Infrared Transmitting Tube LED

The working principle of an infrared transmitting tube LED is based on the semiconductor physics. When a forward voltage is applied to the diode, electrons and holes are injected into the depletion region. The recombination of these electrons and holes releases energy in the form of photons, which are then emitted as infrared radiation. The wavelength of the emitted infrared light is determined by the energy bandgap of the semiconductor material used in the diode.
