Revolutionize Night Vision with Cutting-Edge IR LED Chips!

IR LED chips, or infrared light-emitting diodes, have become an integral part of various electronic devices and systems. These tiny components emit infrared light, which is invisible to the human eye, and are widely used in applications such as remote controls, security systems, and wireless communication. In this article, we will explore the industry of IR LED chips, including their working principles, market trends, and future prospects.

Introduction to IR LED Chips

IR LED chips are semiconductor devices that emit infrared light when an electric current is applied to them. They consist of a PN junction, where electrons and holes recombine, releasing energy in the form of photons. The emitted photons have a wavelength ranging from 700 to 3000 nanometers, which falls within the infrared spectrum. IR LED chips are available in various colors, such as red, near-infrared, and far-infrared, depending on their application.

Working Principles of IR LED Chips

The working principle of IR LED chips is based on the photoelectric effect. When an electric current is applied to the PN junction, electrons and holes are separated, creating a depletion region. As the electrons and holes move towards the junction, they recombine, releasing energy in the form of photons. The wavelength of the emitted photons depends on the energy bandgap of the semiconductor material used in the IR LED chip.

There are two main types of IR LED chips: AlGaAs and InGaAs. AlGaAs-based IR LED chips emit near-infrared light with a wavelength ranging from 850 to 940 nanometers. They are commonly used in applications such as remote controls and security systems. InGaAs-based IR LED chips emit far-infrared light with a wavelength ranging from 1.3 to 3.5 micrometers. They are used in applications such as thermal imaging and night vision.
