Introduction to IR LED 880 nm: A Comprehensive Industry Overview

What is an IR LED 880 nm?

An IR LED 880 nm, also known as an infrared light-emitting diode with a peak emission wavelength of 880 nanometers, is a type of semiconductor device that emits infrared light at a specific wavelength. These LEDs are widely used in various applications, including remote controls, medical devices, and industrial automation. The 880 nm wavelength falls within the near-infrared region of the electromagnetic spectrum, which is invisible to the human eye but can be detected by specialized sensors and cameras.

How does an IR LED 880 nm work?

An IR LED 880 nm operates based on the principle of the photoelectric effect. When an electric current is applied to the diode, electrons and holes are generated within the semiconductor material. These charge carriers recombine, releasing energy in the form of photons. The energy of these photons corresponds to the bandgap of the semiconductor material, which determines the wavelength of the emitted light. In the case of an IR LED 880 nm, the semiconductor material used is typically gallium arsenide (GaAs) or a gallium indium phosphide (GaInP) alloy.
