Infrared IR LED, short for Infrared Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current is applied. It has been widely used in various fields such as remote control, communication, security, and medical equipment. This article will introduce the infrared IR LED industry, including its working principle, application fields, market trends, and future development prospects.

Working Principle of Infrared IR LED

The infrared IR LED is a semiconductor device, which consists of a p-n junction. When an electric current is applied to the p-n junction, electrons and holes are generated due to the electric field. The electrons and holes recombine at the recombination region, releasing energy in the form of photons. These photons are infrared light, which is then emitted from the device. The infrared IR LED has a certain wavelength range, usually between 780nm to 3000nm. The specific wavelength depends on the material composition and structure of the device. The longer the wavelength, the less visible the light is to the human eye.
