[0021] Refer to the attached Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8When the image acquisition device is in use, the camera component 6 shoots and captures images at a specified position. During this process, if the light in the working environment is weak, it will directly affect the effect of image acquisition. Therefore, light compensation is often required during the image acquisition process. For this purpose, a protective shell 701 with an LED light source 718 is fixed on the top of the camera component 6.

While the driving screw 704 rotates to adjust the focal length, it will also drive the driving gear plate 708 to rotate, and thereby the driving gear plate 708 drives the gear ring 712 to rotate. At this time, the linkage gear 713 engaged with the inner side of the gear ring 712 will also drive the aperture blades 714 embedded therein to rotate at a certain angle, so that the plurality of aperture blades 714 are expanded or closed, and the illumination range of the first convex lens 709 is adjusted. When the distance between the second convex lens 717 and the LED light source 718 is shortened, the plurality of aperture blades 714 are gradually closed together to further narrow the illumination range. When the distance between the guide rail 707 and the LED light source 718 is increased, the plurality of aperture blades 714 are gradually expanded and further expand the illumination range.
