Revolutionizing Night Vision: The Cutting-Edge Potential of High Power NIR LED Technology

High power NIR LED (Near-Infrared Light Emitting Diode) technology has been revolutionizing various industries due to its unique properties and wide range of applications. This article aims to provide an in-depth introduction to high power NIR LED technology, its working principles, applications, and future prospects.

Introduction to High Power NIR LED Technology

High power NIR LED technology refers to the generation and emission of near-infrared light with high power output. NIR LEDs are a type of semiconductor devices that emit light in the near-infrared region of the electromagnetic spectrum, which ranges from 750 to 2500 nanometers. The high power NIR LED technology has gained significant attention in recent years due to its high efficiency, long lifespan, and low cost compared to other light sources.

Working Principles of High Power NIR LED

The working principle of a high power NIR LED is based on the semiconductor diode. When an electric current is applied to the diode, electrons and holes recombine in the semiconductor material, releasing energy in the form of light. In the case of NIR LEDs, the semiconductor material used is typically gallium nitride (GaN), which has excellent optical and electrical properties for NIR emission.

The structure of a high power NIR LED typically consists of a p-n junction, where the p-type layer is doped with indium gallium nitride (InGaN) and the n-type layer is doped with gallium nitride (GaN). When an electric current passes through the diode, electrons from the n-type layer move towards the p-type layer, and holes from the p-type layer move towards the n-type layer. As they recombine, they emit near-infrared light.
