Introduction

The infrared light bead, also known as an infrared LED, is a type of semiconductor device that emits infrared light when an electric current passes through it. It has been widely used in various fields such as automotive, medical, consumer electronics, and industrial applications. In this article, we will introduce the infrared light bead industry, including its history, types, applications, and market trends.

History of Infrared Light Bead Industry

The development of the infrared light bead industry dates back to the 1960s when the first infrared LED was invented. Since then, the technology has been continuously improved, and the application range has been expanding. In the 1970s, infrared light beads began to be used in remote controls, and in the 1980s, they were widely used in consumer electronics. With the rapid development of semiconductor technology, the performance of infrared light beads has been greatly improved, and their application fields have been continuously expanded.

Types of Infrared Light Beads

According to the emission wavelength, infrared light beads can be divided into short-wave infrared light beads, mid-wave infrared light beads, and long-wave infrared light beads. The short-wave infrared light beads have a wavelength of 0.76-1.3μm, which is mainly used for remote control and communication. The mid-wave infrared light beads have a wavelength of 1.3-3μm, which is mainly used for thermal imaging and medical diagnosis. The long-wave infrared light beads have a wavelength of 3-5μm, which is mainly used for infrared heating and night vision. According to the material, infrared light beads can be divided into gallium arsenide infrared light beads, gallium phosphide infrared light beads, and other materials. Gallium arsenide infrared light beads have high photoelectric conversion efficiency and long service life, and are widely used in high-end applications. Gallium phosphide infrared light beads have good thermal stability and are suitable for high-temperature environments.
