With the rapid development of technology, infrared LED light has emerged as a key component in various applications. This article aims to provide an in-depth introduction to the infrared LED light industry, covering its history, technology, applications, market trends, and future prospects.

History of Infrared LED Light

The concept of infrared light dates back to the early 19th century when scientists began to explore the electromagnetic spectrum. In the late 19th century, Heinrich Hertz discovered the existence of infrared radiation. However, it was not until the 20th century that infrared LED technology was developed. The first infrared LED was invented by Nick Holonyak Jr. in 1962 at General Electric. Since then, infrared LED technology has been widely used in various fields.

Technology of Infrared LED Light

Infrared LED light is a type of semiconductor light source that emits infrared radiation. The working principle of infrared LED light is based on the electron-hole recombination in the semiconductor material. When electrons and holes recombine, they release energy in the form of photons. The wavelength of these photons determines the color of the light. Infrared LED light has a wavelength range of 700 nm to 1 mm, which is beyond the visible spectrum. The main materials used in infrared LED production include gallium arsenide (GaAs), gallium nitride (GaN), and aluminum gallium arsenide (AlGaAs). These materials have excellent optical and electrical properties, which enable the efficient emission of infrared radiation. The structure of an infrared LED typically consists of a p-n junction, a p-type layer, an n-type layer, and an emission layer.
