IR LED (infrared light-emitting diode): An IR LED (infrared light emitting diode) is a solid state lighting ( SSL ) device that emits light in the infrared range of the electromagnetic radiation spectrum . When a suitable current is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. When electrons and holes are excited and allowed to recombine across the bandgap in a semiconductor, the emitted photon However, its ultimate goal is to replace traditional illumination through LED lamps since LED lighting significantly reduces energy consumption and cuts down on carbon-dioxide emission.
