Introduction to Infrared IR LED Industry

1. Overview of Infrared IR LED

Infrared IR LED, short for infrared emitting diode, is a semiconductor device that emits infrared light when an electric current is applied. As a key component in the infrared sensor field, it plays a crucial role in various applications, such as remote control, security, medical, and communication. The infrared IR LED industry has developed rapidly in recent years, with a wide range of products and technologies emerging.

2. Working Principle of Infrared IR LED

The working principle of infrared IR LED is based on the semiconductor material. When the diode is forward biased, the electrons and holes are recombined at the p-n junction, releasing energy in the form of photons. The photons with longer wavelengths are infrared light, which is why the device is called an infrared IR LED. The wavelength of the emitted infrared light is determined by the bandgap of the semiconductor material, which can be adjusted by selecting different materials.

3. Types of Infrared IR LED

According to the emission wavelength, infrared IR LED can be divided into near-infrared, mid-infrared, and far-infrared. Near-infrared LED has a wavelength range of 700nm to 1400nm, which is widely used in remote control and communication applications. Mid-infrared LED has a wavelength range of 1400nm to 3000nm, mainly used in thermal imaging and gas detection. Far-infrared LED has a wavelength range of 3000nm to 1mm, mainly used in long-distance communication and thermal imaging.
