Introducing the 850nm Infrared LED: A Game-Changer in the Lighting Industry

Introduction to Infrared LEDs

In the realm of lighting technology, the 850nm Infrared LED stands out as a cutting-edge innovation. These LEDs, known for their ability to emit light at a specific wavelength of 850 nanometers, have found numerous applications across various industries. Unlike visible light LEDs, which emit light in the range of 380 to 780 nanometers, 850nm Infrared LEDs produce light that is invisible to the human eye. This unique characteristic makes them ideal for applications where invisible light is required, such as in medical, industrial, and security sectors.

How 850nm Infrared LEDs Work

The 850nm Infrared LED operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in these LEDs is typically made of gallium arsenide (GaAs) or gallium nitride (GaN), which are known for their ability to emit infrared light at the desired wavelength. When an electric current is applied, the electrons and holes in the semiconductor recombine, releasing energy in the form of photons. These photons have a wavelength of 850 nanometers, which falls within the infrared spectrum.
