Problems solved by technology

[0003] The existing switching systems in the market mainly include separate automatic aperture + day and night double switching structure, automatic aperture + single switching structure, and integrated automatic aperture + single switching structure, but the use effect is not ideal. The integrated automatic aperture + single switching The structure doesn't take full advantage of the light when it's low, and splits aren't very practical

Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] Such as Figure 1 to Figure 10 As shown, a component with automatic aperture and day / night switching function includes a mounting base 1 on which a motor 2 and a solenoid valve assembly 3 arranged on one side of the motor 2 are installed. There is a window 11, a first driving lever 21 and a second driving lever 22 are installed at the shaft extension end of the motor 2, a third driving lever 31 is installed at the axial extension end of the solenoid valve assembly 3, and a third driving lever 31 is installed at the first driving lever 21 and the second driving lever. The rod 22 is respectively connected with the first blade 4 and the second blade 5 for adjusting the size of the aperture, a partition 6 is arranged above the first blade 4 and the second blade 5, and a partition corresponding to the window 11 is arranged on the partition 6 . The plate wi...

Abstract

The invention relates to an assembly with an automatic diaphragm and a day / night switching function. The assembly can be automatically adjusted according to external light intensity to acquire high-quality images. A control loop is fed back to a diaphragm control set according to a light intensity signal to control the size of the opening diameter of two blades of a diaphragm caliber set, and excessive exposure in a strong light condition or insufficient quantity of light in a weak light condition is avoided. A day / night dual switching structure is composed of a switcher and a switching set. The switching set is composed of an IR cut-off filter and an all-through spectrum filter. Switching is controlled by a power source. When light is sufficient in the day, the color of an image will be affected due to the fact that all kinds of infrared light will be mixed; at this time, the IR cut-off filter in the switching system works and cuts off unnecessary infrared light, so that the real color of the image will be restored. When light is insufficient at night, the all-through filter glass starts to work, and all light is fully utilized to overcome the defect of low-luminance performance of a camera.

Description

【Technical field】 [0001] The invention relates to an assembly with automatic aperture and day / night switching functions. 【Background technique】 [0002] The automatic aperture is composed of an aperture aperture group and an aperture control group. The control circuit feeds back to the aperture control group according to the light intensity signal to control the opening diameter of the two blades of the aperture aperture group to avoid excessive exposure under strong light conditions or insufficient light under low light conditions. , the day and night double switching is composed of a switcher and a switching group. The switching group is composed of an infrared cut-off filter and a full-transmission spectrum filter. The switcher is controlled by the power supply. Miscellaneous, will affect the image color. At this time, switch the infrared cut filter in the system to work, cut off unnecessary infrared rays, and restore the true color of the image. When the light is insuff...
