Description

Technical Field

[0001] The utility model relates to the technical field of soft light covers, in particular to a soft light cover opening and closing structure. Background Technique

[0002] The technical background of the soft light cover (Softbox) stems from the needs in the fields of photography and lighting. Its invention and wide application are mainly to solve the problems of being too harsh and having too high contrast caused by direct light source. In a photography studio or outdoor shooting, directly using a flash or other point light source forms strong shadows and high-brightness areas, resulting in unnatural photo effects and lack of layering. The design principle of the soft light cover is based on the principle of light diffusion in optics. By adding one or more layers of semi-transparent materials (such as thin cloth, grid or heat dissipation plate) in front of the light source, the originally concentrated and highly directional direct light is converted into a softer, more uniform and broader diffused light. This softened light can effectively reduce the contrast on the surface of the object to be photographed, reduce the hardness of the shadow edge, and make the color transition more delicate and natural. The soft light cover may have first appeared in the professional photography field in the early 20th century. With the development and popularization of photography technology, it has gradually become one of the essential lighting accessories in a photography studio. Modern soft light covers have diverse designs, including different sizes, shapes and internal structures (such as adjustable grids, multi-layer soft cloth, etc.) to adapt to different shooting requirements and scenarios.

[0003] The realization of modern soft light covers usually adopts the following methods: 1. Multi-layer diffusion materials; the soft light cover usually contains one or more layers of semi-transparent diffusion cloth or plastic film inside. These materials can dissipate heat and diffuse the direct light, making the light softer and more uniform. Common diffusion materials include non-woven fabric, silk fabric or special soft light paper. 2. Adjustable structure: Some soft light covers are designed with an inner grid (such as a honeycomb grid) that can be detached or adjusted in position. By changing the distance between the light source and the diffusion material and the number of light rays passing through the diffusion layer, the light quality and brightness can be controlled. 3. Different shapes and sizes: According to the shooting requirements, the soft light cover can have different shapes, such as rectangular, square, octagonal, strip-shaped, etc., and also has various sizes to adapt to different light source sizes and shooting object ranges. Large soft light boxes can even be made into foldable or telescopic types for easy storage and carrying. 4. Additional accessories: Some soft light covers are also equipped with accessories such as baffles and color filters to further control the direction, intensity and color effect of the light. 5. Integrated design: For the soft light cover corresponding to a portable flash, it often adopts a design that can be quickly installed and disassembled. For example, it is fixed around the flash head through Velcro, elastic bands or buckles, and characteristics such as small volume and light weight are considered.

[0004] However, when converting the existing soft light diffuser technology into a landscape art installation, it is found that the existing technical solutions have problems such as being unable to precisely and continuously adjust the light-emitting area, wrinkles appearing when the light film is folded, deformation occurring when the main structure of the soft light diffuser is opened and closed, and it is not aesthetically pleasing from the perspective of interacting with the audience.
