Infrared transmitter diode, also known as infrared LED, is an essential component in the field of infrared communication technology. As a semiconductor device, it can emit infrared light when an electric current passes through it. This article will introduce the infrared transmitter diode industry, including its working principle, application fields, market trends, and future development prospects.

Working Principle of Infrared Transmitter Diode

The infrared transmitter diode is a semiconductor device that utilizes the photoelectric effect. When a forward voltage is applied to the diode, electrons and holes are injected into the depletion layer, and recombination occurs in the active layer. During the recombination process, part of the energy is released in the form of infrared light. The wavelength of the emitted light is determined by the material composition and structure of the diode. The working principle of the infrared transmitter diode can be described as follows: 1. When the diode is forward biased, electrons and holes are injected into the depletion layer. 2. Recombination occurs in the active layer, and part of the energy is released in the form of infrared light. 3. The emitted light is modulated by the input signal, and the intensity and frequency of the light change accordingly.
