This article aims to provide an in-depth introduction to infrared light beads, their working principles, applications, and the potential future developments in this field.

What are Infrared Light Beads?

Infrared light beads, also known as infrared emitting diodes (LEDs), are semiconductor devices that emit infrared light when an electric current passes through them. These beads are typically made of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs) materials, which possess excellent infrared emission properties. Due to their compact size and high efficiency, infrared light beads have become a popular choice for various applications in different industries.

Working Principles of Infrared Light Beads

The working principle of infrared light beads is based on the semiconductor material's ability to emit light when an electric current is applied. When the electric current passes through the semiconductor material, electrons and holes recombine, releasing energy in the form of photons. In the case of infrared light beads, these photons are in the infrared spectrum, which is not visible to the human eye. The emitted infrared light has a wavelength ranging from 700 to 3000 nanometers, depending on the material composition and design of the infrared light bead. This range allows infrared light beads to be used for various applications, such as remote controls, infrared communication, and sensing.
