High power infrared LED, also known as high-power infrared light-emitting diode, is a type of semiconductor device that emits infrared light with high intensity. With the rapid development of technology, high-power infrared LED has become an indispensable part of various fields, such as automotive, medical, security, and consumer electronics. This article will introduce the industry of high-power infrared LED, including its working principle, application fields, market trends, and future development prospects.

Working Principle of High Power Infrared LED

High power infrared LED is a semiconductor device that emits infrared light through the injection of electrons and holes into the active region. When electrons and holes recombine, they release energy in the form of photons, which are then emitted as infrared light. The working principle of high-power infrared LED is similar to that of a normal LED, but with higher power and longer wavelength. The main components of a high-power infrared LED include the p-n junction, the active region, and the package. The p-n junction is the core part of the LED, where electrons and holes recombine. The active region is a layer with a certain thickness, where the recombination of electrons and holes occurs. The package is used to protect the LED and improve its heat dissipation performance.
