Introduction

Infrared light beads, also known as infrared emitting diodes (LEDs), have gained significant attention in various industries due to their unique properties and applications. These tiny semiconductor devices emit infrared light when an electric current passes through them. 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 development of gallium arsenide (GaAs) and other III-V compound semiconductors paved the way for the creation of infrared light-emitting diodes. Since then, the technology has evolved significantly, with continuous improvements in efficiency, brightness, and lifespan.

Technology of Infrared Light Beads

Infrared light beads are typically made of III-V compound semiconductors, such as gallium arsenide (GaAs), gallium nitride (GaN), and indium phosphide (InP). These materials have a direct bandgap, which allows them to emit infrared light when an electric current is applied. The structure of an infrared light bead typically consists of a p-n junction, where the p-type and n-type regions are doped with different impurities to create a potential barrier. The key factors affecting the performance of infrared light beads include the material quality, device structure, and fabrication process. High-quality materials with low defect density are crucial for achieving high brightness and efficiency. Additionally, optimizing the device structure, such as the thickness of the active layer and the reflector design, can enhance the light output and reduce the heat generation.
