High power NIR LED, or high power near-infrared light-emitting diode, is a crucial component in various fields, such as medical imaging, telecommunications, and industrial automation. This article aims to provide an in-depth introduction to the industry of high power NIR LED, covering its basic principles, applications, and market trends.

Basic Principles of High Power NIR LED

High power NIR LED is a type of semiconductor light-emitting device that emits near-infrared light. Compared with traditional LEDs, high power NIR LED has higher luminous efficiency, longer lifespan, and better stability. The working principle of high power NIR LED is based on the injection of electrons and holes into the semiconductor material under forward bias, and the recombination of electrons and holes in the active layer to emit photons. The key factors affecting the performance of high power NIR LED include the material composition, structure design, and fabrication process. The most commonly used materials for high power NIR LED are gallium nitride (GaN), aluminum gallium nitride (AlGaN), and indium gallium nitride (InGaN). Among them, GaN-based high power NIR LED has the advantages of high brightness, high efficiency, and long lifetime.
