This article will introduce the industry of high output IR LED, including its definition, working principle, applications, market status, and future development prospects.

Definition and Classification of High Output IR LED

High output IR LED is a kind of semiconductor device that can emit infrared light with high luminous intensity. It is mainly composed of a p-n junction, and its working principle is based on the injection of electrons and holes into the semiconductor material to generate infrared light. According to the different wavelengths of emitted infrared light, high output IR LED can be divided into near-infrared, mid-infrared, and far-infrared categories.

Working Principle of High Output IR LED

The working principle of high output IR LED is based on the p-n junction. When the diode is forward biased, electrons and holes are injected into the semiconductor material. As the electrons and holes move to the depletion region, they collide and recombine, releasing energy in the form of infrared light. The luminous intensity of the LED is determined by the number of electrons and holes recombining and the recombination efficiency.
