Problems solved by technology

[0004] In the camera field, we cannot change the diameter of the lens at will for the already manufactured lens, so we have added an aperture system. The main parameter controlled by the aperture system is the exposure. Exposure is a very important parameter. In bright daylight , we hope to receive less light; and on nights with less light, we hope to collect more light. Size, while the traditional aperture is composed of two blades, when the aperture changes, the aperture area is not uniform, nor is it in a controllable state, it gradually becomes inapplicable in the digital camera system
[0005] Most of the apertures on the market are controlled by solenoid valves and Hall elements, which is difficult to control

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] Such as Figure 1 to Figure 9 As shown, a multi-leaf aperture adjustment device with filter switching includes a mounting base plate 1 on which a motor 2 and a solenoid valve assembly 3 arranged on one side of the motor 2 are installed. A circular window 101 is arranged on the surface of the installation base 1, and a boss 102 is arranged on the inner surface of the installation base 1 along the outer circumference of the circular window 101. Protruding pillars 103 distributed in a circular array, a turntable 4 is installed on the boss 102, a turntable through hole 401 communicating with the circular window 101 is provided on the turntable 4, and a turntable through hole 401 communicated with the circular window 101 is arranged on the turntable 4. A plurality of shifting columns 402 are arranged on the surface, a shifting fork 403 is arranged on the o...

Abstract

The invention relates to a multi-leaf aperture adjustment device with filter switching, which has the function of automatic switching between an infrared cut-off filter and a full-transmission spectrum filter, and the aperture is close to a circle at any time, and the area of ​​the aperture is between A controllable state, the size of the aperture area changes uniformly to adjust the size of the exposure, the automatic switching of the filter and the uniform change of the multi-leaf aperture area can obtain higher quality and clearer images than traditional cameras or cameras.

Description

[0001] 【Technical field】 [0002] The invention relates to a multi-leaf aperture adjustment device with filter switching. [0003] 【Background technique】 [0004] In the camera field, we cannot change the diameter of the lens at will for the already manufactured lens, so we have added an aperture system. The main parameter controlled by the aperture system is the exposure. Exposure is a very important parameter. In bright daylight , we hope to receive less light; and on nights with less light, we hope to collect more light. Size, while the traditional aperture is composed of two blades. When the aperture changes, the aperture area does not change uniformly, nor is it in a controllable state, which gradually becomes inapplicable in the digital camera system. [0005] Most of the apertures on the market are controlled by solenoid valves and Hall elements, which is difficult to control. [0006] 【Content of invention】 [0007] The technical problem to be solved by the present i...
