Working Principle of Infrared LED 8mm

The working principle of an infrared LED 8mm is based on the photoelectric effect. When an electric current is applied to the semiconductor material, it generates heat, which excites the electrons in the material. These excited electrons then recombine with the holes in the material, releasing energy in the form of photons. The photons emitted have a wavelength in the infrared spectrum, which is beyond the visible range of human eyes. The 8mm infrared LED is made of a semiconductor material, typically gallium arsenide (GaAs) or gallium phosphide (GaP), which has a direct bandgap structure. This structure allows the infrared photons to be efficiently emitted from the LED.
