This article aims to provide an in-depth introduction to the high power NIR LED industry, covering its basic principles, technological advancements, market trends, and future prospects.

Introduction to High Power NIR LED

High power NIR LED refers to a type of semiconductor light-emitting diode that emits light in the near-infrared spectrum, typically ranging from 700 to 2500 nanometers. Unlike visible light, NIR light is not visible to the human eye, making it ideal for applications that require invisible light transmission or detection. High power NIR LED is characterized by its high brightness, high efficiency, and long lifespan, which make it a preferred choice for various applications in the industry.

Basic Principles of High Power NIR LED

The working principle of high power NIR LED is based on the semiconductor material’s ability to emit light when an electric current passes through it. The semiconductor material used in high power NIR LED is typically gallium nitride (GaN), which has excellent electrical and optical properties. When an electric current is applied to the GaN material, electrons and holes recombine, releasing energy in the form of light. The wavelength of the emitted light is determined by the energy bandgap of the semiconductor material.
