High power infrared transmitter diode, also known as infrared LED, is a semiconductor device that emits infrared light when a forward voltage is applied. It has been widely used in various fields such as industrial automation, remote control, and optical communication. In this article, we will introduce the industry of high power infrared transmitter diode, including its working principle, types, applications, and market trends.

Working Principle of High Power Infrared Transmitter Diode

High power infrared transmitter diode is a kind of semiconductor device with a PN junction. When a forward voltage is applied to the diode, electrons and holes are injected into the PN junction, and then recombine in the active layer. During the recombination process, the energy of the electrons is released in the form of infrared light. The higher the injection current, the higher the power output of the diode.

Types of High Power Infrared Transmitter Diode

High power infrared transmitter diodes can be divided into several types according to their wavelength, such as near-infrared, mid-infrared, and far-infrared. Among them, near-infrared diodes have the shortest wavelength and are widely used in remote control, optical communication, and industrial automation. Mid-infrared diodes have a longer wavelength and are mainly used in infrared imaging and thermal imaging.
