An infrared transmission tube, also called an infrared light emitting diode, as part of a diode. You can directly convert electrical energy to near infrared rays. Light (invisible) and radiation from light emitting devices. It is mainly used in all kinds of photoelectric switches and long-distance transmission circuits. The structure of the infrared transmission tube is the same as that of a normal light emitting diode in principle, and uses only different semiconductor materials. Infrared LEDs are commonly used with gallium arsenide (GaAs), aluminum gallium arsenide (GaAlAs), and other materials, with clear or light blue black resin encapsulation.
