Working Principle of Infrared Transmitting Tube LED

The infrared transmitting tube LED is a semiconductor device that converts electrical energy into infrared light. It consists of a p-n junction, which is formed by diffusing a p-type semiconductor material into an n-type semiconductor material. When a forward voltage is applied to the p-n junction, electrons and holes are injected into the junction. As they recombine, energy is released in the form of infrared light. The working principle of the infrared transmitting tube LED can be described as follows: 1. Electrons and holes are injected into the p-n junction. 2. As electrons and holes recombine, energy is released in the form of infrared light. 3. The infrared light is emitted from the surface of the semiconductor material. The key parameters of the infrared transmitting tube LED include the wavelength, luminous intensity, and forward voltage. The wavelength of the infrared light emitted by the LED determines its application field. For example, short-wavelength infrared light is commonly used in remote control applications, while long-wavelength infrared light is used in thermal imaging.
