In the 1950s, the United States successfully developed the first infrared transmitting tube LED. Since then, the infrared transmitting tube LED industry has developed rapidly, and its technology has been continuously optimized and improved.

Working Principle of Infrared Transmitting Tube LED

The working principle of the infrared transmitting tube LED is based on the photoelectric effect. When the forward bias voltage is applied to the PN junction of the semiconductor material, the electrons and holes are separated, and the electrons move towards the P region, releasing energy in the form of infrared light. The wavelength of the emitted infrared light is determined by the energy gap of the semiconductor material. Generally, the infrared transmitting tube LED emits infrared light with a wavelength of 850nm to 950nm.
