Revolutionizing Night Vision Technology: The Rise of High Power NIR LED Innovations

High power NIR LED, or High Power Near-Infrared Light Emitting Diode, has become a crucial 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 high power NIR LED industry, covering its definition, working principle, applications, market trends, and future prospects.

Definition and Working Principle of High Power NIR LED

High power NIR LED refers to a type of LED with a wavelength range of 750nm to 2500nm, which is close to the infrared region of the electromagnetic spectrum. It is characterized by high power output, high efficiency, and low cost. The working principle of high power NIR LED is based on the semiconductor material, which emits light when electrons and holes recombine.

The high power NIR LED is typically made of gallium nitride (GaN) or indium gallium nitride (InGaN) as the active layer. The semiconductor material is sandwiched between two p-type and n-type layers, which form a PN junction. When a forward bias voltage is applied to the PN junction, electrons and holes are injected into the active layer, and the recombination of electrons and holes emits light.
