Working Principles of LED Infrared Transmitting Tube

The LED infrared transmitting tube is a semiconductor device that emits infrared light when an electric current passes through it. It consists of a p-n junction, where electrons and holes recombine, releasing energy in the form of infrared radiation. The emitted light has a wavelength range of approximately 780 to 3,000 nanometers, which falls within the infrared spectrum. The working principle of an LED infrared transmitting tube can be summarized as follows:

1. Electrical excitation: When an electric current is applied to the LED, electrons and holes are injected into the p-n junction.
2. Recombination: Electrons and holes recombine in the active region of the LED, releasing energy in the form of infrared radiation.
3. Light emission: The emitted infrared light is then transmitted through the lens or optical fiber, reaching the receiving device.
