Mini IR LED, short for Mini Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light at a specific wavelength. With the rapid development of the electronics industry, mini IR LED has been widely used in various fields such as consumer electronics, automotive, medical, and industrial. This article will introduce the industry of mini IR LED, including its definition, application fields, market status, and future development trends.

Definition and Working Principle of Mini IR LED

Mini IR LED is a semiconductor device that emits infrared light with a specific wavelength. It is composed of a p-n junction, and when the forward voltage is applied, electrons and holes recombine at the junction, releasing energy in the form of infrared light. The mini IR LED has the advantages of small size, high brightness, long life, and low power consumption.

The working principle of mini IR LED is similar to that of a common LED. The main difference is that the material and structure of the mini IR LED are different. The material used in the mini IR LED is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), and the structure is typically a single-junction or multi-junction structure. The emission wavelength of the mini IR LED is typically between 780nm and 1000nm, which is in the near-infrared region of the electromagnetic spectrum.
