The invention relates to the technical field of soft light boxes, in particular to a size-adjustable soft light box for a photographic lamp.
Background
When a picture is taken indoors, at night, or in an environment where the light is not sufficiently bright, an auxiliary light source is generally provided by using a flash lamp in order to obtain a clear and clear picture. Flash typically includes both self-contained and external access provisions for the camera. The soft light box comprises a soft light box, a flashlight and a soft light box, wherein the soft light box is arranged on the soft light box, the flashlight is arranged on the soft light box, the soft light box is arranged on the soft light box, and the soft light box is arranged on the soft light box.
The Chinese patent publication number is: CN100487553C patent discloses a method for assembling a soft light box body and a soft light box for photography. Firstly, mounting a plurality of support rods on a central connecting component one by one; applying a pre-tightening force to tighten the supporting rods in pairs, and pre-positioning the supporting rods to form a supporting frame matched with the shape of the outer cover; then the outer cover is arranged on the periphery of the supporting frame; then the prepositioning of the support rod is removed, and the support rod is tightly sleeved on the outer cover at the periphery of the support rod. The soft light box comprises a central connecting assembly, a plurality of supporting rods, an outer cover and a pre-tightening device for pre-tightening the supporting rods to form a supporting frame. The pre-tightening force is provided through the pre-tightening device, the supporting frame which is convenient for the outer cover to be sleeved is formed, the supporting rod is kept in a shape in the assembling process, the outer cover can be conveniently sleeved to the periphery of the supporting frame, the operation difficulty is low, the supporting rod cannot generate a tensioning force for the outer cover, the defect that the outer cover is torn in the prior art is avoided, and the pre-tightening device has the advantages of convenience and safety in assembling.
In the above patent, although the advantages of convenient and safe assembly are provided, and the outer cover can be prevented from being torn, in practical use, we find that there still exist certain disadvantages, such as:
1. the size of the soft light box is not convenient to adjust, and the required photographing areas are different according to different photographed objects, so that photographing lamps with different specifications need to be prepared, and the cost is increased;
2. the light on the soft light plate of the soft light box is not uniform enough, and because the position of the light source and the center of the soft light plate are in the same straight line, the light at the center of the soft light plate is always particularly bright, and the light at the edge is relatively dim, so that the light is not uniform enough.
Based on this, we propose a soft light box of a photographic lamp with adjustable size, which hopefully solves the disadvantages in the prior art.

when the telescopic rods 7 on the control plates 8 at the left side and the right side extend out, the four control plates 8 arranged in a rectangular shape longitudinally expand, the openings are enlarged, and meanwhile, the elastic support frames 5 movably arranged on the outer walls of the connecting columns 6 generate elastic deformation to adapt to the positions of the control plates 8;
when the telescopic rods 7 on the control plates 8 on the left side and the right side retract, the four control plates 8 which are arranged in a rectangular shape longitudinally shrink, the openings become small, and meanwhile, the elastic deformation of the elastic support frames 5 movably arranged on the outer walls of the connecting columns 6 is recovered, so that the positions of the control plates 8 are self-adapted;
therefore, the relative positions of the four control panels 8 can be adjusted by shifting the driving wheels 18 on the different control panels 8, and the opening size of the soft light box is changed to generate different photographing areas;
when the relative positions of the four control plates 8 are adjusted, the rotating column 4 can rotate in the fixed cylinder 3, the bolt 30 needs to be screwed to enable the fixture block 31 at the tail end of the bolt 30 to be separated from the clamping groove 28, the locking of the rotating column 4 is released, and after the relative positions of the four control plates 8 are adjusted, the bolt 30 is screwed to enable the fixture block 31 at the tail end of the bolt 30 to be clamped in the clamping groove 28 again, so that the position of the rotating column 4 can be limited again, the rotating column 4 is prevented from rotating, and the elastic support frame 5 is prevented from shifting left and right;
the position of lamp holder corresponds with the position of the groove 36 that is in the light, and the shape of lamp holder outer wall couples with the shape of the groove 36 inner wall that is in the light, the light that the end of lamp holder sent penetrates light groove 36 department and can be blocked, prevent this department light from penetrating directly, the light that the side of lamp holder sent is even jets out from the light path passageway of a plurality of spotlight section of thick bamboo 38, the reflection of light ball 39 of the internal wall of spotlight section of thick bamboo 38 can reflect light, make light at spotlight section of thick bamboo 38 internal loop refraction, with light intensive dispersion, finally, the light of intensive dispersion is thrown on the gentle cloth 9 after the refraction of reflection of cloth, can make the light of gentle cloth 9 department more even, soft, can not take place the middle bright, the dark condition in edge, the result of use of gentle case has been improved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
