This article provides an in-depth introduction to the industry of infrared beam diodes, covering their working principles, applications, market trends, and future prospects.

Introduction to Infrared Beam Diodes

Infrared beam diodes, also known as infrared light-emitting diodes (LEDs), are semiconductor devices that emit infrared radiation when an electric current passes through them. These diodes are widely used in various fields due to their high efficiency, compact size, and low cost. The infrared radiation emitted by these diodes has a wavelength range of 700 nm to 1 mm, which is beyond the visible spectrum.

Working Principles of Infrared Beam Diodes

The working principle of infrared beam diodes is based on the photoelectric effect. When an electric current is applied to the diode, electrons and holes are generated in the semiconductor material. As these charge carriers recombine, they release energy in the form of photons. The wavelength of the emitted photons depends on the energy bandgap of the semiconductor material. Infrared beam diodes are typically made of materials such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs).
