This article aims to provide a comprehensive introduction to the 850nm infrared LED industry, covering their working principles, applications, market trends, and future prospects.

Introduction to Infrared 850nm LEDs

Infrared 850nm LEDs are a type of light-emitting diode that emits infrared light at a wavelength of 850 nanometers. These LEDs have several advantages over other types of infrared light sources, such as reduced power consumption, smaller size, and longer lifespan. They are widely used in various applications, including communication, security, and medical fields.

Working Principles of Infrared 850nm LEDs

The working principle of an infrared 850nm LED is based on the photoelectric effect. When a forward voltage is applied to the LED, electrons and holes are injected into the active region. The recombination of these electrons and holes releases energy in the form of photons, resulting in the emission of infrared light. The specific wavelength of the emitted light is determined by the energy bandgap of the semiconductor material used in the LED.
