Background of Infrared Transmitter Diode Model

Infrared transmitter diode model is an important component in the field of infrared communication technology. As a kind of semiconductor device, it can convert electrical energy into infrared light energy, and then transmit it through the air to achieve the purpose of communication. With the rapid development of infrared communication technology, the application of infrared transmitter diode model has become more and more extensive. This article will introduce the infrared transmitter diode model, its working principle, characteristics, and application fields.

Working Principle of Infrared Transmitter Diode Model

The infrared transmitter diode model is based on the PN junction of a semiconductor. When the diode is forward biased, electrons and holes are injected into the depletion region, which is a high resistance region. Due to the energy difference between electrons and holes, electrons and holes are recombined, releasing energy in the form of photons. These photons are in the infrared spectrum, which is why the diode is called an infrared transmitter diode. The working principle of the infrared transmitter diode model can be described as follows: 1. Forward bias: When the diode is forward biased, the voltage at the anode is higher than the voltage at the cathode, which causes electrons and holes to inject into the depletion region. 2. Recombination of electrons and holes: Electrons and holes in the depletion region are recombined, releasing energy in the form of photons. 3. Infrared light emission: The photons released by the recombination of electrons and holes are in the infrared spectrum, which is emitted from the diode as infrared light.
