Introduction to Infrared IR LED Industry

1. Definition and Overview of Infrared IR LED

Infrared IR LED, short for Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current passes through it. As a key component in the infrared application field, infrared IR LED has been widely used in various fields such as remote control, security, communication, and medical treatment. With the continuous development of infrared technology, the application range of infrared IR LED is expanding, and its market demand is increasing. Infrared IR LED is divided into two types according to the wavelength: near-infrared and far-infrared. Near-infrared IR LED has a shorter wavelength, usually ranging from 0.75 to 3.0 micrometers, while far-infrared IR LED has a longer wavelength, usually ranging from 3.0 to 30 micrometers. The characteristics of infrared IR LED include high brightness, low power consumption, fast response, and stable performance.

2. Working Principle of Infrared IR LED

The working principle of infrared IR LED is based on the semiconductor p-n junction. When an electric current passes through the p-n junction, the electrons and holes in the semiconductor material are excited and recombine, releasing energy in the form of infrared light. The intensity of the emitted light is proportional to the injection current, and the wavelength of the emitted light is determined by the energy gap of the semiconductor material. The semiconductor material commonly used in infrared IR LED is gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have a suitable energy gap to emit infrared light in the desired wavelength range. In addition, the structure of the infrared IR LED also plays an important role in its performance. Generally, the structure includes a p-type layer, an n-type layer, and an active layer. The p-type layer and the n-type layer are used to form the p-n junction, while the active layer is used to emit infrared light.
