Infrared transmitter diode model, as an essential component in the field of infrared communication, plays a crucial role in the transmission of infrared signals. This article aims to provide an in-depth introduction to the infrared transmitter diode model, covering its basic principles, types, applications, and future development trends.

Basic Principles of Infrared Transmitter Diode Model

The infrared transmitter diode model is based on the principle of light-emitting diode (LED). When the diode is forward biased, electrons and holes are injected into the active region of the diode. Due to the recombination of electrons and holes, energy is released in the form of photons, which are emitted as infrared light. The wavelength of the emitted light is determined by the material composition and structure of the diode.
