2. Working Principle of Infrared LED Light

The working principle of infrared LED light is based on the photoelectric effect. When the forward voltage is applied to the semiconductor material, electrons and holes are generated in the depletion layer. As the electrons and holes recombine, they release energy in the form of photons. The photons emitted have a wavelength in the infrared range, which is the infrared LED light. The semiconductor material used in the infrared LED light is usually gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs). These materials have good photoelectric properties and can efficiently convert electrical energy into infrared radiation.
