Basic Principles of 880 nm Infrared LED
The 880 nm infrared LED is a kind of light-emitting diode with a wavelength of 880 nm. It is a semiconductor device that emits infrared light when an electric current is applied. The basic principle of its operation is based on the energy band structure of the semiconductor material. When the forward bias voltage is applied to the PN junction, the electrons and holes in the semiconductor material are excited and recombine, releasing energy in the form of photons. The photons with a wavelength of 880 nm are infrared light.
