Infrared emitting tubes are mainly used in various photoelectric switches and remote control emitting circuits. They have the functions of fast response and low energy consumption.
Infrared emission tube, an electrostatic control electronic tube that generates or amplifies high-frequency power, sometimes also known as an oscillation tube. The transmission tube used in audio or switching circuits is called modulation tube. Transmission tube is the main electronic device in radio broadcasting, communication, television transmission equipment and industrial high-frequency equipment
About 75% of the DC input power of the anode of the launch tube is converted into the high-frequency output power, and the remaining 25% is the anode heat loss. Therefore, the anode of the launch tube must be cooled. The anode of the medium and small power emitting tube is naturally cooled and made of nickel, molybdenum or graphite. It is installed in the tube shell and the working temperature can reach 600 ℃. The anodes of high-power emitting tubes are all made of copper, and as a part of the vacuum sealed tube shell, various forced cooling methods are adopted.
Emission distance, emission angle (15 degrees, 30 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees, 180 degrees), emitted light intensity and wavelength. The above are physical parameters, and it is necessary to understand its electrical performance parameters: 3mm and 5mm are small-power infrared emitting tubes commonly used in the market

 

Infrared lamps have different powers and two wavelengths of 850nm and 940nm. The selection of wavelength depends on
Listed factors:
1. If the user does not mind that the light of the infrared lamp is visible to the naked eye, the infrared lamp of 850nm due to its illumination distance
Far, good effect, should be the first choice.
2. If the problem of red storm is considered, 940nm infrared lamp must be used, and low illumination camera shall be selected
Machine.
3. Select a lens with a large relative aperture.
4. The divergence angle of the infrared lamp shall match the field angle of the lens
