Description

Lens structure for camera light filling

Technical Field

The utility model belongs to the technical field of the optical accessories, especially, relate to a lens structure for camera light filling.

Background

For guaranteeing that the camera still can the work of taking a picture under the dark condition, use the light filling lamp to carry out the light filling to the camera among the prior art, but the light filling effect that uses the light filling lamp alone still has limitations such as the spotlight effect is poor, the spotlight scope is little, and the image quality that leads to the camera to shoot is relatively poor, can not satisfy the work demand under its dark surrounds.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a lens structure for camera light filling has enlarged light irradiation angle and visual area scope, provides necessary hardware support to camera all ring edge borders photographic demand under the dark condition.

In order to achieve the above purpose, the technical scheme of the utility model is realized like this:

a lens structure for camera light supplement comprises an elliptical lens body, wherein the elliptical lens body is divided into a left visual area and a right visual area; the left visual area and the right visual area both comprise at least one small area, the small areas are lens sheets provided with Fresnel grains, and the small areas are focused on the positions of the light supplement lamps of the cameras.

Further, the small blocks of the left visual area and the small blocks of the right visual area are arranged in parallel in a straight line, and have an optical included angle of 120 degrees;

the centers of the concentric circles of the Fresnel lines of each small block of the left visual area and each small block of the right visual area are all positioned on the long axis of the ellipse, and the centers of the circles are sequentially arranged from left to right.

Furthermore, the circle center of the concentric circle of the fresnel patterns of the small block at the left edge of the left visual area is located on a vertical central line of the left visual area, and the circle center of the concentric circle of the fresnel patterns of the small block at the right edge of the right visual area is located on a vertical central line of the right visual area.

Furthermore, a small block is arranged in each of the left visual area and the right visual area, and the two small blocks are arranged in the same width.

Compared with the prior art, a lens structure for camera light filling have following advantage:

the utility model provides a lens structure ingenious utilization fresnel principle to camera dark ring border application demand, makes its spotlight effect and spotlight scope in looking aside the region and overlooking the region all obtain the increase, controls the light filling angle and can reach 120 degrees, and spotlight is effectual, satisfies camera all ring edge borders under the dark condition and takes pictures the light filling demand.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, the lens structure for camera light supplement is a detection structure in which two large areas, namely a left visual area 1 and a right visual area 2, are transversely arranged and combined in a plane to form a whole ellipsoid, and 1 light supplement lamp is matched to form a large-angle light supplement and a large visual area range. The lens structure is divided into a left visual area and a right visual area, and the left direction and the right direction are focused respectively. Left side visual area 1, right visual area 2 all are 1 layer of structural layer, all set up a little block promptly, the lens piece that the little block all is provided with fresnel texture all focuses on in the light filling lamp position of camera, and the farthest light filling distance of left visual area 1 and right visual area 2 all is 4 meters. The concrete structure is as follows:

the 2 small blocks of the left and right visual areas are arranged in an equal width mode and are arranged in parallel in a straight line, an optical included angle of 120 degrees is formed, the light supplementing angle and the light condensation range of the lens are enlarged, and the light condensation effect is improved. The circle centers of the concentric circles of the Fresnel lines of the small blocks in the left visual area 1 and the small blocks in the right visual area 2 are located on the long axis of the ellipse, the circle centers of the concentric circles of the Fresnel lines of the small blocks in the left visual area 2 are sequentially arranged from left to right, the circle center of the concentric circle of the Fresnel lines of the small blocks in the left visual area 1 is located on a vertical central line of the concentric circles, and the circle center of the concentric circles of the Fresnel lines of the small blocks in the right visual area 2 is located on a vertical central line of the concentric circles, so that the light condensation effect of the lens is improved.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
