Introduction to Infrared LEDs 850

What are Infrared LEDs 850?

Infrared LEDs, also known as infrared light-emitting diodes, are electronic devices that emit infrared light when an electric current is applied to them. The term "850" refers to the wavelength of the infrared light emitted by these diodes, which is 850 nanometers (nm). Infrared LEDs 850 are widely used in various applications due to their unique properties and advantages.

How do Infrared LEDs 850 Work?

Infrared LEDs 850 work on the principle of electroluminescence. When an electric current is applied to the diode, electrons and holes recombine at the p-n junction, releasing energy in the form of photons. These photons have a wavelength of 850 nm, which falls within the infrared spectrum. The emitted infrared light is invisible to the human eye, making it suitable for applications where visible light is undesirable or harmful.
