Advantages of dot matrix infrared cameras compared to ordinary infrared cameras

The dot matrix camera is a kind of infrared camera. The ordinary infrared camera is composed of many LED lights, and the dot matrix camera has only one lamp. So what are the advantages of dot matrix infrared cameras compared to ordinary infrared cameras?

Advantage 1: long life

Dot matrix infrared technology ensures the good working condition of the CCD, and its service life is 9 times that of the ordinary LED infrared camera. The ordinary LED infrared camera places the LED light-emitting tube and the camera in one cavity, and the heat of the LED tube cannot be effectively radiated through the PCB board, and the temperature problem seriously restricts the service life of the CCD.

Advantage 2: High efficiency

The luminous efficiency and heat dissipation performance of the semiconductor itself is a benign 裓-ring. The better the heat dissipation performance, the lower the operating temperature, the lower the operating temperature and the better the luminous efficiency. On the contrary, it is a vicious circle of declining efficiency.

Advantage three: high brightness

The higher the brightness, the farther the illumination interval is. The output power of a single LED is generally 5~15mW. Although the current can be increased by increasing the current, the limitation of the material itself is that the photoelectric conversion efficiency of infrared is not high. With only 20 lights, the remaining 80 is heat. In addition, multiple LEDs are equipped with a PCB board as a carrier, and the heat dissipation performance is not good. The light source of the dot-matrix infrared camera is equipped with a good heat-conducting device by encapsulating several 10 high-efficiency and high-power wafers into one plane. At the same time increase its photoelectric conversion efficiency, the brightness is about 100 times that of a single LED.

Advantage four: ray uniform

When four infrared LEDs are paired with the camera lens for 4 weeks, the emitted light is composed of a plurality of spot stacks, and the brightness of the stacked portions is particularly high, and also constitutes a circle. The dot-matrix infrared camera is equivalent to a large point light source. Through special optical imaging, the light is evenly illuminated to the monitored object, and the brightness of the obtained monitoring picture is consistent with the brightness of 4 weeks.

Advantage 5: small size

As mentioned earlier, array infrared uses a highly integrated advanced packaging technology, and an array of infrared chips with a few 10 wafers is packaged. The small size is the most convenient assumption. It is assumed that several 10 LEDs with a single LED are installed. On a high speed dome, the effect is imaginable.

The advantages of dot-matrix infrared cameras compared with ordinary infrared cameras are reflected in the above five points. These five points are long life, high efficiency, high brightness, uniform light and small volume.
