This article aims to provide an in-depth introduction to the near infrared LED light industry, covering its history, technology, applications, market trends, and future prospects.

History of Near Infrared LED Light Technology

The development of near infrared LED light technology dates back to the early 20th century when the first LED was invented. However, it was not until the late 1990s that near infrared LEDs started to gain attention due to advancements in semiconductor materials and manufacturing processes. Since then, the technology has evolved rapidly, leading to the development of high-efficiency, high-brightness near infrared LEDs.

Technology of Near Infrared LED Light

Near infrared LEDs are semiconductor devices that emit light in the near infrared spectrum, which ranges from 750 to 2500 nanometers. The key to the technology lies in the semiconductor materials used to create the LED. Common materials include gallium nitride (GaN), aluminum gallium nitride (AlGaN), and indium gallium nitride (InGaN). These materials can be doped with different elements to tune the emission wavelength and improve the performance of the LED.

The manufacturing process of near infrared LEDs involves several steps, including epitaxial growth, wafer slicing, dicing, and packaging. Epitaxial growth is a technique used to create a thin layer of semiconductor material on a substrate. Wafer slicing involves cutting the epitaxial layer into thin wafers, which are then diced into individual LEDs. Finally, the LEDs are packaged to protect them and facilitate their integration into various applications.
