How to solve the heat radiation problem of the array infrared camera?

Array infrared camera refers to the IRIR lamp whose core is LEDIRArray. LEDArray refers to a light emitting diode array, which is an efficient and long-lived infrared night vision device. Different from the traditional LED infrared lamp, the outstanding feature of the array infrared lamp is long service life, no significant attenuation of light in 2~3 years, even light, fine picture quality and high definition. The night vision image of the array camera is bright and bright. Little, no vignetting, no even dark corners of the image, largely solves the flashlight effect of the picture, can significantly improve the night vision effect of the camera, and at the same time greatly reduce the volume of the digital video file, saving the hard disk recorder space.

Traditional LED infrared lamps have been widely used due to their low price, occupying 95% of the current market for infrared cameras. However, its shortcomings such as fast light decay, short life, and low power are the main reasons for dissatisfaction with LED infrared cameras. With the development of infrared technology, past technological bottlenecks are also making breakthroughs: heat dissipation problems, service life problems, effective conversion of infrared light, and advanced product design concepts are all making breakthroughs. Array-based infrared cameras are aimed at solving LED problems. The new infrared technology was born out of the flaws.

In the process of use, how can the problem of heat dissipation from the array infrared camera be solved?

1, reduce the current. The use of infrared lamps with low power consumption instead of high-power infrared lamps, although reducing the amount of heat, but in the long-range radiation, the effect is certainly not as good as the latter.

2, in the array of infrared cameras plus cooling fan, this effect is certainly there, but that is the test of the fan is very strict, and added a fan for the design of the shell is also a test, to ensure beauty but also practical .

3, using a constant current power supply. Keep the current constant and control the heat dissipation of the LED.

4, LED lights arranged in groups. For example, with 24 infrared, it can be arranged in 3 groups to reduce heat.

5, the choice of structural materials. For example, LED lamps and housings use aluminum alloys and other heat-dissipating materials.

6, the use of automatic cooling and air conditioning with a cooling effect of forced cooling, automatic adjustment of the internal temperature of the array infrared camera, a good solution to this problem.
