NIR LED light, or near-infrared light-emitting diode, has become an essential component in various industries due to its unique properties and wide range of applications. This article aims to provide an in-depth introduction to the NIR LED light industry, covering its history, technology, applications, market trends, and future prospects.

History of NIR LED Light

The concept of near-infrared light dates back to the early 20th century when scientists began to study the properties of infrared radiation. However, it was not until the 1960s that the first infrared light-emitting diode (LED) was developed. Since then, the technology has undergone significant advancements, leading to the development of NIR LED light.

Technology of NIR LED Light

NIR LED light is a type of semiconductor device that emits near-infrared light with a wavelength ranging from 700 to 2500 nanometers. The technology behind NIR LED light involves the use of gallium arsenide (GaAs), gallium nitride (GaN), and other semiconductor materials. These materials have excellent properties for emitting near-infrared light, such as high efficiency, low power consumption, and long lifespan. The manufacturing process of NIR LED light involves several steps, including epitaxy, wafer slicing, dicing, and packaging. Epitaxy is the process of growing a thin layer of semiconductor material on a substrate. Wafer slicing involves cutting the epitaxial wafer into thin slices, and dicing is the process of cutting these slices into individual LEDs. Finally, packaging involves enclosing the LED in a protective housing and connecting it to a circuit.
