Introduction

Infrared light beads, also known as infrared emitting diodes (LEDs), have become increasingly popular in various industries due to their excellent performance and wide range of applications. These tiny beads emit infrared light, which is invisible to the naked eye but can be detected by special sensors and devices. 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 was discovered in the early 19th century by British astronomer William Herschel. However, it was not until the 20th century that infrared light technology began to develop rapidly. In the 1960s, the invention of the infrared LED marked the beginning of a new era in infrared light technology. Since then, infrared light beads have been widely used in various fields, such as consumer electronics, medical equipment, and industrial automation.

Technology of Infrared Light Beads

Infrared light beads are semiconductor devices that emit infrared light when an electric current passes through them. The core component of an infrared light bead is a semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When an electric current is applied, the electrons and holes in the semiconductor material recombine, releasing energy in the form of infrared light. The key factors affecting the performance of infrared light beads include the material, structure, and manufacturing process. Different materials and structures can produce light beads with different wavelengths, intensities, and emission angles. The manufacturing process also plays a crucial role in determining the quality and reliability of infrared light beads.
