Introduction to Infrared Transmitter Diode Model

Infrared transmitter diode model, also known as infrared LED (Light Emitting Diode), is a semiconductor device that can emit infrared light when an electrical current passes through it. It is widely used in various fields, such as remote control, infrared communication, and optical communication. The infrared transmitter diode model is characterized by its compact size, low power consumption, and high reliability.

Working Principle of Infrared Transmitter Diode Model

The working principle of the infrared transmitter diode model is based on the photoelectric effect of semiconductor materials. When the forward bias voltage is applied to the diode, the electrons in the conduction band are injected into the valence band, resulting in the generation of infrared photons. The intensity of the emitted infrared light is proportional to the injection current. The structure of the infrared transmitter diode model usually includes a p-n junction, a cathode, and an anode. The p-n junction is the core part of the diode, which can convert electrical energy into light energy. The cathode and anode are connected to the external circuit, and the forward bias voltage is applied to the diode through them.
