Description

Technical Field

[0001] The utility model relates to the technical field of soft boxes, in particular to a color changing component for a photography soft box. Background Art

[0002] A softbox is a device used by photographers to soften light. Its main components include a diffuser, a wire support rod, and a chuck. In typical use, the wire support rod is fixed to the chuck, and the diffuser is extended from the rod to soften the photographic light and reduce flare and shadows. However, commercially available softboxes primarily refract light, typically changing the direction of the light source and not its color. This limits their applicability in shooting scenarios requiring different light colors, making them difficult to meet the demand for diverse light colors.

[0003] Chinese patent CN219715897U discloses a color-changing device for a softbox. The document describes the device's operating principle as follows: First, a fixed tube is mounted on the softbox via a spring hook. Then, a filter of a different color is replaced and clamped onto a filter holder. The filter holder, magnetically attracted by a magnet and a metal sheet, secures the filter to the mounting ring, which is then attached to the mounting ring by a magnet. This allows the color of the softbox's projected light to be changed to suit the photographer's needs. Furthermore, ventilation slots on the outer side of the fixed tube dissipate heat from the softbox's light source.

[0004] The color adjustment device in this patent needs to replace a different filter film each time the color is changed, so multiple filter films are needed. In view of this, the number of filter films is further reduced and the color changing device is improved. Utility Model Content

[0005] In response to the above problems, a photography softbox color changing assembly is provided, comprising a fixed tube for connecting to the softbox, a conical tube fixedly connected to the upper end of the fixed tube, an installation box provided above the conical tube, a filter mechanism provided in the installation box, the filter mechanism comprising three movable disks, a filter film provided at the center position of the movable disk, the filter films on the three movable disks are respectively a yellow filter film, a cyan filter film and a magenta filter film, three movable slots adapted to the models of the movable disks are provided in the filter mechanism, the movable disk moves in the installation box through the movable slots, when light of the corresponding color is needed, the required filter film is retained in the installation box, and the other two filter films are pulled out of the installation box through the movable disk, thereby achieving the purpose of color changing, and magnet sheets are provided on the inner wall of the installation box and the movable disk for positioning.

[0006] Preferably, when red light is needed, the cyan filter film is pulled out of the installation box, and the yellow filter film and the magenta filter film are left in the installation box.

[0007] Preferably, when green light is needed, the magenta filter film is pulled out of the installation box, and the yellow filter film and the cyan filter film are left in the installation box.

[0022] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figures 1-6 : A photography soft light box color changing component includes a fixed tube 1 for connecting to the soft light box, the upper end of the fixed tube 1 is fixedly connected to a conical tube 2, a mounting box 3 is provided above the conical tube 2, and a filter mechanism 31 is provided in the mounting box 3, the filter mechanism 31 includes three movable disks 311, the center position of the movable disk 311 is provided with a filter film, the filter films on the three movable disks 311 are respectively a yellow filter film 312, a cyan filter film 313 and a magenta filter film 314, and the filter mechanism 31 is provided with three movable slots 32 adapted to the model of the movable disk 311. The movable disk 311 moves in the mounting box 3 through the movable slots 32. When light of the corresponding color is needed, the required filter film is retained in the mounting box 3, and the other two filter films are pulled out of the mounting box 3 through the movable disk 311, thereby achieving the purpose of changing color. A magnet sheet 4 is provided on the inner wall of the mounting box 3 and the movable disk 311 for positioning.

[0024] In the prior art, each color change requires replacing the filter. To address this, the present invention first introduces a fixed tube 1, which connects to the softbox. A conical tube 2 is fixedly attached to the upper end of the fixed tube 1, and a mounting box 3 is located above the conical tube 2. Inside the mounting box 3, a filter mechanism 31 is located. This filter mechanism 31 consists of three movable disks 311, each with a filter film positioned at its center. These filters are yellow, cyan, and magenta. To facilitate the movement of the filters, the mounting box 3 is also equipped with three movable slots 32 corresponding to the sizes of the movable disks 311. The movable disks 311 are moved within the mounting box 3 via these slots. When a specific color of light is desired, the user can place the desired filter film inside the mounting box 3 via the movable disks 311 and remove the other two unnecessary filters, along with the movable disks 311, from the mounting box 3, thereby changing the color of the softbox light. In order to ensure the accurate positioning of the filter film and the movable plate 311, magnets 4 are installed on the inner wall of the installation box 3 and the movable plate 311. In this way, the user can quickly replace the filter film as needed to achieve the purpose of changing the color of the light projected by the soft box.

[0025] Reference Figure 2 When red light is needed, the cyan filter film 313 is pulled out from the installation box 3, and the yellow filter film 312 and the magenta filter film 314 are left in the installation box 3.

[0026] When red light is needed, the user operates the filter mechanism 31, pulling the cyan filter 313 out of the mounting box 3 via the movable slot 32. Cyan filter 313 absorbs red light, and removing it allows red light to pass through. Meanwhile, the yellow filter 312 and magenta filter 314 remain in the mounting box 3. The combination of the yellow and magenta filters 314 produces a mixture of red light, allowing the softbox to project red light through adjustment of the filter mechanism 31. The magnets 4 on the inner wall of the mounting box 3 and the movable plate 311 act as a positioning mechanism during this process, ensuring the accuracy of the filter's movement and positioning.

[0027] Reference Figure 2 When green light is needed, the magenta filter film 314 is pulled out from the installation box 3, and the yellow filter film 312 and the cyan filter film 313 are left in the installation box 3.

[0028] When green light is needed, the user operates the filter mechanism 31, pulling the magenta filter 314 out of the mounting box 3 via the movable slot 32. Magenta filter 314 absorbs green light, and removing it allows green light to pass through. Meanwhile, the yellow filter 312 and cyan filter 313 remain in the mounting box 3. Since the combination of yellow and cyan light produces green light, this combination allows the softbox to project green light. Magnets 4 on the inner wall of the mounting box 3 and on the movable plate 311 ensure the accuracy and stability of the filter during movement and positioning.

[0029] Reference Figure 2 When blue light is needed, the yellow filter film 312 is pulled out from the installation box 3, and the magenta filter film 314 and the cyan filter film 313 are left in the installation box 3.

[0030] When blue light is needed, the user operates the filter mechanism 31, pulling the yellow filter 312 out of the mounting box 3 via the movable slot 32. Because yellow filter 312 absorbs blue light, removing it allows blue light to pass through. Meanwhile, the magenta filter 314 and cyan filter 313 remain in the mounting box 3. The combination of magenta filter 314 and cyan filter 313 produces a mixture of blue light, allowing the softbox to project blue light. The magnets 4 on the inner wall of the mounting box 3 and the movable plate 311 act as a positioning mechanism during this process, ensuring the accuracy and stability of the filter during movement and positioning.

[0031] Reference Figure 2 : When primary color light is needed, just pull all the filters out of the mounting plate.

[0032] When natural or white light, unfiltered by any color filters, is desired, the user operates the filter mechanism 31, pulling all filters—yellow filter 312, cyan filter 313, and magenta filter 314—out of the mounting box 3 via the movable slot 32. With all filters removed, the light is no longer subject to color filtering and can be projected directly through the softbox, restoring its original color. The magnets 4 on the inner wall of the mounting box 3 and the movable tray 311 assist in positioning the filters during this process, ensuring their accuracy and stability during movement and complete removal.

[0033] Reference Figure 1-Figure 2 : A plurality of right-angle plates 5 are fixedly mounted on the outer side wall of the fixed tube 1 , and a spring hook 6 is movably connected to the right-angle plate 5 , and the fixed tube 1 is connected to the soft box via the spring hook 6 .

[0034] Several right-angled plates 5 are fixedly mounted on the outer wall of the fixed tube 1. These plates 5 are movably connected to spring hooks 6. The elasticity of these spring hooks 6 allows the fixed tube 1 to be easily connected to the softbox. The design of the spring hooks 6 allows the fixed tube 1 to be quickly installed and fixed to the softbox's wire support rod or other connection points. The elasticity of the spring hooks 6 also provides a certain degree of adjustment to accommodate softboxes of different sizes and shapes, ensuring that the color change assembly can be stably installed on the softbox.
