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 used in various applications, including remote controls, communication systems, and security systems. Infrared transmitting tube LEDs are widely used due to their compact size, low power consumption, and high efficiency.

How Does an Infrared Transmitting Tube LED Work?

An infrared transmitting tube LED works on the principle of semiconductor physics. It consists of a p-n junction, where electrons and holes recombine, releasing energy in the form of infrared radiation. When an electric current is applied to the diode, electrons move from the n-type semiconductor to the p-type semiconductor, creating a depletion region. This region acts as a barrier, preventing the flow of current. However, when electrons recombine with holes, they release energy in the form of infrared radiation. The wavelength of the emitted infrared radiation depends on the composition of the semiconductor material used in the diode. Common materials used in infrared transmitting tube LEDs include gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium nitride (InGaN). These materials emit infrared radiation in the range of 700 to 3000 nanometers.
