Abstract
A liquid crystal diaphragm for an optical lens comprises a liquid crystal screen, an outer frame and a control line, wherein the liquid crystal screen is arranged in the middle of the outer frame and is connected to a control unit through the control line, and the light emitting state of each light emitting point on the liquid crystal screen is controlled by the control unit; various optional diaphragm models are preset in the control unit, and after the diaphragm models are selected, the control unit controls the states of all points of the liquid crystal screen, so that the states of the points corresponding to the models are different. The utility model realizes the change of the clear aperture of the lens by utilizing the switching effect of the liquid crystal, can also change the shape of the diaphragm at will, and changes the picture color effect by utilizing the control selection of the liquid crystal control through different color lights; the utility model discloses the mode of present mechanical adjustment light transmission volume has been replaced in the electronization, and noise, fatigue stress, the problem that the precision descends that machinery produced when not using have humanized selected advantage moreover, are fit for all kinds of preference crowds.
Description
Technical Field
The utility model relates to a light column field, concretely relates to liquid crystal light column for optical lens.
Background
The middle of the camera lens is generally provided with a component capable of changing the clear aperture, namely a commonly-known adjustable diaphragm, which is used for controlling the exposure amount so as to enable a user to obtain a high-quality image. The diaphragm can also obtain background blurring patterns with different shapes when in shooting through designs with different shapes, such as a circle, a polygon and the like, so as to form different illusion effects.
The existing diaphragm mainly comprises a plurality of diaphragm blades, different light-transmitting apertures can be obtained by changing the positions of the blades, and the current changing mode is manual and electric. At present, all diaphragms have single shapes, and after a lens is designed, the lens is fixed, so that a user cannot change the diaphragm, and the application range is limited.
Disclosure of Invention
According to the problem that the background art provided, the utility model provides an optical lens is solved with liquid crystal light fence, it is right next the utility model discloses do further to explain.
A liquid crystal diaphragm for an optical lens comprises a liquid crystal screen, an outer frame and a control line, wherein the liquid crystal screen is arranged in the middle of the outer frame and is connected to a control unit through the control line, and the light emitting state of each light emitting point on the liquid crystal screen is controlled by the control unit; various optional diaphragm models are preset in the control unit, and after the diaphragm models are selected, the control unit controls the states of all points of the liquid crystal screen, so that the states of the points corresponding to the models are different.
Optionally, a sealant is arranged at a joint of the liquid crystal display and the outer frame for sealing.
Optionally, the liquid crystal screen is coplanar with the surface of the outer frame, and a tempered protective layer is arranged outside the surfaces of the liquid crystal screen and the outer frame to protect the liquid crystal screen.
Has the advantages that: compared with the prior art, the utility model utilizes the switching effect of the liquid crystal to realize the change of the clear aperture of the lens, can also randomly change the shape of the diaphragm, and utilizes the liquid crystal control to change the picture color effect through the control selection of different color lights; the utility model discloses the mode of present mechanical adjustment light transmission volume has been replaced in the electronization, and noise, fatigue stress, the problem that the precision descends that machinery produced when not using have humanized selected advantage moreover, are fit for all kinds of preference crowds.
Drawings
FIG. 1: the structure of the utility model is shown schematically;
in the figure: liquid crystal screen 1, frame 2, control line 3.
Detailed Description
A specific embodiment of the present invention will be described in detail with reference to fig. 1.
The utility model provides a liquid crystal diaphragm for optical lens, includes LCD screen 1, frame 2 and control line 3, LCD screen 1 sets up in frame 2 middle part, and LCD screen 1 is connected to the control unit through control line 3, and the luminous state of each luminous point on LCD screen 1 is controlled by the control unit.
The method comprises the steps that each luminous point on the liquid crystal screen 1 is provided with a mapping position in a control unit, various optional diaphragm models are preset in the control unit, after the diaphragm models are selected, the control unit controls the state of each point of the liquid crystal screen 1, so that the states of the points corresponding to the models are different, according to an optical principle, light which can penetrate through each selected point on the liquid crystal screen 1 can be absorbed by black points which are not selected, further, external light can only penetrate through a selected area of the liquid crystal screen 1, in addition, each point on the liquid crystal screen 1 can only penetrate through the light with the same color as the point, color light represented by other frequencies can be absorbed and cannot penetrate through the points, so that the control unit can control the frequency of the light which penetrates through each point on the liquid crystal screen 1, and further, the picture color effect is.
And a sealant is arranged at the joint of the liquid crystal screen 1 and the outer frame 2 for sealing.
The liquid crystal screen 1 and the outer frame 2 are coplanar, and a toughened protective layer is arranged outside the surfaces of the liquid crystal screen 1 and the outer frame 2 to protect the liquid crystal screen 1.
The utility model discloses the switch effect who utilizes liquid crystal realizes that the camera lens clear aperture changes, can also alternate the shape of diaphragm at will, and utilizes the control selection of liquid crystal control through different colour light, changes picture color effect.
Theoretically, the utility model discloses can set for the diaphragm of arbitrary shape and arbitrary color scope, and then obtain the effect of required printing opacity volume and printing opacity shape and printing opacity color, just the utility model discloses electronization has replaced the mode of present mechanical adjustment printing opacity volume, and noise, fatigue stress, the decline problem of precision that machinery produced when not only using have humanized selected advantage moreover, are fit for all kinds of preference crowds.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
