With the rapid development of technology, infrared (IR) LED nm has become a hot topic in the industry. This article will introduce the concept, application, and future development of IR LED nm, aiming to provide a comprehensive understanding of this field.

Introduction to IR LED nm

Infrared LED nm refers to the infrared light-emitting diode with a specific wavelength. The "nm" here represents nanometers, which is a unit of length used to measure the wavelength of light. The wavelength of IR LED nm typically ranges from 780nm to 2500nm, covering the near-infrared, mid-infrared, and far-infrared regions.

Working Principle of IR LED nm

The working principle of IR LED nm is based on the semiconductor material. When the forward voltage is applied to the diode, electrons and holes are injected into the active layer. Due to the recombination of electrons and holes, photons are emitted, which are infrared light. The specific wavelength of the emitted light depends on the composition and structure of the semiconductor material.
