Infrared beam diode, also known as infrared LED, is a semiconductor device that emits infrared light. It has been widely used in various fields such as communication, medical treatment, security, and automotive. This article will introduce the infrared beam diode industry, including its working principle, types, applications, and market trends.

Working Principle of Infrared Beam Diode

The infrared beam diode is a semiconductor device, which is made of a semiconductor material such as gallium arsenide (GaAs) or indium phosphide (InP). The working principle of the infrared beam diode is based on the photoelectric effect. When the forward voltage is applied to the diode, electrons and holes are generated in the depletion region. The electrons and holes recombine in the active region, releasing energy in the form of infrared light.

Types of Infrared Beam Diodes

According to the wavelength of the emitted light, infrared beam diodes can be divided into three types: near-infrared, mid-infrared, and far-infrared.

• Near-infrared diodes: The wavelength range is 0.7-1.3μm, commonly used in remote control, optical communication, and medical equipment.
• Mid-infrared diodes: The wavelength range is 1.3-3μm, widely used in gas sensing, spectroscopy, and medical diagnosis.
