Introduction

Infrared light beads, also known as infrared emitting diodes (LEDs), have become increasingly popular in various industries due to their unique properties and applications. These tiny semiconductor devices emit infrared light, which is invisible to the human eye but can be detected by specialized sensors. This article aims to provide an in-depth introduction to the infrared light bead industry, covering its history, technology, applications, 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 semiconductors. In the 1960s, the first infrared emitting diodes were developed, marking the beginning of the infrared light bead industry. Over the years, advancements in semiconductor technology have led to the development of more efficient and reliable infrared light beads.

Technology of Infrared Light Beads

Infrared light beads are made of semiconductor materials, typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to emit infrared light when an electric current is applied. The process of manufacturing infrared light beads involves several steps, including epitaxial growth, doping, and packaging. Epitaxial growth is a technique used to create a thin layer of semiconductor material on a substrate. This layer is then doped with impurities to alter its electrical properties. Finally, the doped layer is encapsulated in a package that protects the device and allows it to emit infrared light. The key parameters that determine the performance of an infrared light bead include its emission wavelength, intensity, and beam angle. These parameters can be tailored to meet the specific requirements of different applications.
