Infrared emitting tubes are also called infrared emitting diodes, which belong to the category of diodes. It is a light-emitting device that can directly convert electrical energy into near-infrared light (invisible light) and radiate it out. It is mainly used in various photoelectric switches and remote control transmitter circuits. The structure and principle of the infrared emitting tube 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.

Emission distance, emission angle (15 degrees, 30 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees, 180 degrees), the intensity of the emitted light, and the wavelength. The above are physical parameters, and you need to understand its electrical performance parameters: commonly used in the market diameter 3mm, 5mm for low-power infrared emission tubes, 8mm, 10mm for medium power and high-power emission tubes. Low-power transmitter tube forward voltage: 1.1-1.5V, current 20ma, medium power is forward voltage: 1.4-1.65V 50-100ma, high-power transmitter tube is forward voltage: 1.5-1.9V200-350ma. Yuxing Electronics The 1-10W high-power infrared emitting tube can be used in infrared monitoring lighting.
