Infrared transmitting tube, also known as an infrared light-emitting diode, as part of the diode. It is can convert electrical energy directly into the near-infrared. Light (not visible) and the radiation out of the light-emitting device, mainly used in all kinds of photoelectric switch and remote transmission circuits. Infrared transmitting tube structure, the principle of similar to an ordinary light-emitting diode, just use different semiconductor materials. Infrared LEDs are typically used gallium arsenide (GaAs), aluminum gallium arsenic (GaAlAs), and other materials, the use of transparent or light blue, black resin encapsulation.
