Infrared LED
Feb 10, 2021
Infrared light-emitting diodes are also called infrared emitting diodes. They are light-emitting devices that can directly convert electrical energy into infrared light (invisible light) and radiate out. They are mainly used in various light-controlled and remote-control transmitting circuits.
The structure and principle of infrared light-emitting diodes are similar to those of ordinary light-emitting diodes, except that the semiconductor materials used are different. Infrared light-emitting diodes usually use gallium arsenide (GaAs), gallium aluminum arsenide (GaAlAs) and other materials, and are packaged in fully transparent or light blue, black resin.
Commonly used infrared light-emitting diodes include SIR series, SIM series, PLT series, GL series, HIR series and HG series.
