Photography lamp soft light box with adjustable size

Abstract

The invention relates to the technical field of softboxes, and discloses a size-adjustable photoflood light softbox. The softwbox comprises a clamping ring, wherein a mounting plate is fixedly mounted on the outer wall of the clamping ring, fixing cylinders are fixedly mounted on the left side and the right side of the outer wall of the mounting plate correspondingly, and rotating columns are rotationally arranged in the two fixing cylinders correspondingly; and a locking device which is arranged in the fixed cylinder and is used for locking the position of the rotating column. Light rays emitted by the tail end of the lamp holder directly irradiate to the light blocking groove and can be blocked, direct light rays at the light blocking groove are prevented, light rays emitted by the side face of the lamp holder are evenly emitted out of light path channels of the multiple light gathering cylinders, the light rays can be reflected through the light reflecting balls on the inner walls of the light gathering cylinders, the light rays are circularly refracted in the light gathering cylinders and fully dispersed, and finally, the fully dispersed light rays are refracted by the reflective cloth and then projected to the soft light cloth, so the light rays at the soft light cloth are more uniform and soft, the situation that the middle is bright and the edges are dark is avoided, and the use effect of the soft light box is improved.

Description

technical field [0001] The invention relates to the technical field of soft boxes, in particular to a size-adjustable soft box for photographic lights. Background technique [0002] When taking pictures indoors, at night, etc. in an environment that is not bright enough, in order to obtain sharp and clear photos, flashlights are usually used to provide auxiliary light sources. The flash generally includes two ways of providing the camera itself and external access. Among them, the external access can be divided into two ways of using the flash directly on the object to be photographed, and the combination of the flash and the soft box. When using the soft box, the light emitted by the flash is dispersed according to the shape of the soft box. Openly, the texture and color of the object to be photographed can achieve the effect under natural light, so the soft box is favored by the majority of users.

AI Technical Summary

Problems solved by technology

[0005] 1. The size of the above-mentioned soft box is not easy to adjust. Depending on the object to be photographed, the required photographic area is also different, so it is necessary to prepare photographic lights of different specifications, which increases the cost;

[0006] 2. The light on the soft board of the above-mentioned soft box is not uniform enough. Since the position of the light source is on the same straight line as the center of the soft board, the light at the center of the soft board is always particularly bright, and the light at the edge is relatively smooth. Relatively dim, which leads to uneven lighting
