Abstract
The invention relates to a set top flash lamp soft light cover for a digital single lens reflex camera, which comprises a cover body (1), wherein the front side surface of the cover body (1) is provided with a plurality of arc-line-shaped grooves (2) in equidistant arrangement which are distributed on the whole front side surface; the center of a circle where each arc line-shaped groove is located is positioned at a center point (O) of the cover body (1); the front side surface of the cover body (1) is further provided with four straight line guiding light guide grooves (3); and the four light guide grooves (3) are intersected at the center point (O) and end points are all positioned at the edge of the cover body (1). On the basis of a Fresnel lens, the cover body is additionally provided with the four straight line light guide grooves intersected at the center point of the cover body, of which the end points are positioned at the edge of the cover body, so that flash lamp light transmitted from the cover body is more uniform and soft, and peripheral dark regions are eliminated.
Description
technical field
The present invention relates to a kind of soft light cover, particularly a kind of slr camera machine top diffuser shade for flash lamp.
background technology
Soft light cover is mounted in a kind of device intense light being played to softening effect on flashlamp.The light that flashlamp can send by it, if direct projection light, refracted ray, reflection ray, scattered beam, diffracted ray etc. are by resistant to elevated temperatures translucent plastic, is converted into soft diffused light, eliminates the high hot spot on subject.
The cover of existing soft light cover is generally plane or the cover with some small embossments, therefore object still easily over-exposed, depth of field degree is poor.And the focus due to flashlamp is generally positioned at the centre of soft light cover, when the irradiation light transmission soft light cover that flashlamp sends is beaten on object, the intensity of illumination in centre is comparatively large, and surrounding still exists dark space, causes imaging effect poor.
On the other hand, existing soft light cover need in use install, the used time does not pull down, and disassembling operations is loaded down with trivial details and fragile, install and use convenient all not.
Summary of the invention
Technical matters to be solved by this invention is, provides a kind of slr camera machine top diffuser shade for flash lamp, first, cover body through flashlamp light more even, soft, and eliminate periphery dark space; The second, cover body has orientable different rotary position, to avoid the handling repeatedly of cover body.To overcome the defect of existing soft light cover.
It is as follows that the present invention solves the problems of the technologies described above adopted technical scheme:
A kind of slr camera machine top diffuser shade for flash lamp, comprises cover body, the leading flank of described cover body be provided be covered with whole before this
Some the arc shaped grooves equidistantly arranged of side, the center of circle of these circles residing for arc shaped groove is all positioned at the central point of cover body, it is characterized in that: the leading flank of described cover body is also provided with the guide-lighting groove of four straight line trends, and described four guide-lighting grooves intersect at described central point and end points is all positioned at cover body edge.
Angle between two adjacent guide-lighting grooves is 45 °.
Also comprise the link hinged with cover body; The rear end of link is provided with the clamping seat for being connected with camera hotshoe seat.
The inwall of the left and right two-end part of the trailing flank of described cover body is respectively arranged with the hinged-support with axis hole; Link front end is with two front arms, and the front end of two front arms is respectively arranged with the jointed shaft be arranged in described axis hole.
Two described front arms are also respectively arranged with locating convex block; Described hinged-support is provided with the first detent and the second detent that match with locating convex block; Described first detent is positioned at the rear of hinged-support axis hole, and the second detent is positioned at the below of axis hole.
Good effect of the present invention is: the first, cover body has additional four and intersects at described cover body central point and end points is all positioned at the guide-lighting groove of straight line at cover body edge on the basis of Nie Feier lens, from cover body through flashlamp light more even, soft, and eliminate periphery dark space.The second, cover body is connected with camera hotshoe seat by link, and has two orientable position of rotation, during use, cover body is positioned flashlamp front, and when not using, rotation cover body makes it fold and is positioned flashlamp side.Thus avoid the handling repeatedly of cover body.

embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, the present invention includes cover body 1, the leading flank of described cover body 1 is provided with and is covered with this leading flank whole
The arc shaped grooves 2 of some equidistant arrangements, the center of circle of these circles residing for arc shaped groove is all positioned at the central point O of cover body 1, makes cover body 1 become Nie Feier form of lens.The leading flank of described cover body 1 is also provided with the guide-lighting groove 3 of four straight line trends, and described four guide-lighting grooves 3 intersect at described central point O and end points is all positioned at cover body 1 edge.Angle between two adjacent guide-lighting grooves 3 is 45 °.
As shown in Figure 2,3, the present invention also comprises link 5, and link 5 front end, with two front arms, is provided with clamping seat 6 bottom the rear end of described link 5.Clamping seat 6 is provided with clamping guide rail 8 for being connected with camera hotshoe seat.Described clamping seat 6 can also be provided with camera support mounting groove 7.The inwall at the both ends, left and right of the trailing flank of described cover body 1 is respectively arranged with the hinged-support 4 with axis hole, the front end of two described front arms is respectively arranged with jointed shaft 9, and described jointed shaft 9 is connected in the axis hole of two hinged-supports 4.
As shown in Figure 2,3, 4, two front arms of described link 5 are also respectively arranged with locating convex block 10.Described hinged-support 4 is provided with the first detent 11 and the second detent 12 matched with locating convex block 10.Described first detent 11 is positioned at the rear of hinged-support 4 axis hole, and the second detent 12 is positioned at the below of axis hole.
