Infrared light beads, also known as infrared LED beads, are compact and efficient sources of infrared light. These tiny semiconductor devices have found extensive applications in various industries due to their versatility and compact size. This article provides an in-depth introduction to the infrared light bead industry, covering its history, technology, applications, market trends, and future prospects.

History of Infrared Light Beads

The concept of infrared light beads dates back to the early 20th century when scientists began to explore the properties of infrared radiation. However, it was not until the 1960s that the first practical infrared LED was developed. Since then, the technology has evolved significantly, leading to the production of infrared light beads that are now widely used in various applications.

Technology of Infrared Light Beads

Infrared light beads are based on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The process involves the injection of electrons and holes into the semiconductor material, which recombine and release energy in the form of photons. In the case of infrared light beads, these photons have wavelengths longer than those of visible light, falling within the infrared spectrum. The semiconductor material used in infrared light beads is typically a compound semiconductor, such as gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to efficiently emit infrared light when excited by an electric current. The structure of an infrared light bead typically includes a p-n junction, which is responsible for the generation of infrared light.
