High power NIR LED, or high power near-infrared light-emitting diode, has become a significant technology in various fields, particularly in the optical communication and medical industries. This article aims to provide an in-depth introduction to the high power NIR LED industry, covering its definition, working principles, applications, market trends, and future prospects.

Definition and Working Principles

High power NIR LED refers to a type of light-emitting diode that emits near-infrared light with a wavelength ranging from 750 to 2500 nanometers. Compared with traditional LED, high power NIR LED has higher luminous intensity and can emit more intense light. The working principle of high power NIR LED is based on the electroluminescence effect, where electrons and holes are injected into the semiconductor material under the action of electric field, and then recombine to emit photons with a certain wavelength.
