Introduction to the 850nm Infrared Lamp Bead Industry

What is an Infrared Lamp Bead 850nm?

The 850nm infrared lamp bead, also known as an infrared LED, is a type of semiconductor light-emitting diode that emits infrared light at a wavelength of 850 nanometers. It is widely used in various applications, including consumer electronics, medical devices, and industrial automation. The 850nm wavelength falls within the near-infrared spectrum, which is invisible to the human eye but can be detected by some electronic devices.

How Does an Infrared Lamp Bead Work?

An infrared lamp bead works on the principle of the PN junction. When a forward voltage is applied to the diode, electrons and holes recombine at the PN junction, releasing energy in the form of photons. These photons have a wavelength of 850nm, which corresponds to the near-infrared region of the electromagnetic spectrum. The emitted light is then focused through a lens or reflector to produce a concentrated beam.
