Description

Technical Field

[0001] This utility model belongs to the technical field of photographic auxiliary equipment, and in particular relates to a softbox and a softbox system. Background Technology

[0002] In current shooting scenarios, softboxes are often needed as an auxiliary tool. Softboxes convert the direct light from the fill light into diffused light, making the light softer and eliminating highlights on the subject, resulting in a more natural shooting effect. However, in current technology, most softboxes simply have a cover to reflect the light or use a transparent cloth to diffuse the light source. Softboxes have a small diffusion angle and are inconvenient to install. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a diffuser and a diffuser system, which can not only increase the light diffusion angle through multiple reflections on the reflective surface, resulting in a better diffuser effect, but also be easy to install and quick to disassemble.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a softbox, comprising:

[0005] The base has a through hole in the middle;

[0006] A reflector base is provided on the periphery of the base and has a mounting port for the light source to extend into;

[0007] Adapter unit for detachable connection of light source and / or photographic equipment;

[0008] The reflector and the base cooperate to form a diverging cavity, which has at least a first reflective surface, a second reflective surface and a diverging surface. The light emitted by the light source is refracted by at least the first reflective surface and the second reflective surface before being emitted from the diverging surface.

[0009] This invention transforms direct light from a light source into soft, diffused light through reflection from a first and second reflective surface, resulting in a wider light emission angle and softer light. Two or more reflective surfaces can be added inside the diffuser cavity to reflect the light multiple times, further enhancing the soft light effect. The adapter unit can be freely connected to a light source and / or photographic equipment, offering high flexibility in use, and its simple installation structure makes it easy to manufacture.

[0010] Furthermore, the reflector includes an outer body and an inner body, with the outer wall of the inner body forming the first reflective surface and the inner wall of the outer body forming the second reflective surface. The outer wall of the inner body and the inner wall of the outer body reflect light, and the softening effect of the light can be changed by altering the surface roughness of the inner and outer bodies.

[0011] Furthermore, at least a portion of the outer wall of the inner seat is inclined outward from the center towards the side where the mounting opening is located, towards the side where the diverging surface is located; at least a portion of the inner wall of the outer seat is inclined outward from the center towards the side where the mounting opening is located, towards the side where the diverging surface is located. The different inclination angles of the inner and outer seats cause the light emitted from the light source to be reflected sequentially by the inclined first and second reflective surfaces, resulting in the light rays being directed in different directions. This significantly increases the range of light illumination and allows the light to be concentrated towards the diverging surface along a predetermined target path without weakening the light intensity.

[0012] Furthermore, the adapter unit includes at least a first magnetic component, a second magnetic component that can be magnetically connected to the first magnetic component, and a fixing base. The first and second magnetic components are respectively disposed on the base and the fixing base. The fixing base is used for detachable connection of the light source and / or photographic equipment. The adapter unit is magnetically connected to the base and detachably connected to the light source and photographic equipment, making it more convenient to assemble and disassemble during use, and easier to store and carry.

[0013] Furthermore, the mounting base has an adapter section that can be detachably connected to photographic equipment, and a snap-fit ​​part that can be detachably connected to a light source. The adapter unit can freely connect to a light source and / or photographic equipment, offering high flexibility in use, and its installation structure is simple and easy to manufacture.

[0014] Furthermore, the base is at least partially flared and conical, with the inner diameter of the flared and conical portion gradually increasing from the side where the light source is located to the side where the diverging surface is located, and the axial projection of the flared and conical portion coincides with the axial projection of the light source. This allows the base to block part of the strong light from the light source, reducing the light intensity and preventing strong light from affecting the lens framing.

[0015] Furthermore, the first magnetic component is disposed on the base and includes a plurality of circumferentially spaced magnets; the second magnetic component is disposed on the fixing base and is a ring-shaped metal component. The magnetic connection between the base and the adapter unit is achieved through the magnetic attraction of the first and second magnetic components, facilitating quick installation or removal of the diffuser.

[0016] Furthermore, the radiating surface is provided with a diffuser plate, which fills the space between the outer wall of the connecting base and the inner wall of the reflector base; magnets one and two, which can attract each other, are provided between the diffuser plate and the reflector base. The diffuser plate further diffuses the light in all directions, making the light diffusion range wider, and the magnetic connection is convenient for disassembly.

[0017] This utility model also discloses a soft light system, including a light source, the aforementioned soft light cover, and a diffuser plate disposed on the radiating surface, wherein the light source is detachably connected to the adapter unit.

[0018] Furthermore, the base includes a cylindrical section and a flared conical section, and the light source is a ring-shaped light source connected between the cylindrical section and the mounting opening. The cylindrical section serves to support and mount the light source, preventing it from wobbling within the mounting opening.

[0019] The beneficial effects of this utility model are: 1) Two or more reflective surfaces can be set in the diffuser cavity to reflect the light multiple times, resulting in a better soft light effect; 2) Through the reflection of the first and second reflective surfaces, the direct light from the light source is converted into soft diffused light, making the light softer. The first and second reflective surfaces are set at different angles, so that the light emitted from the light source in a straight line is reflected by the first and second reflective surfaces in sequence, and the light is directed in different directions, greatly increasing the range of light illumination. Moreover, it can be concentrated and emitted towards the diffuser surface according to the set target route without weakening the light intensity; 3) The magnetic connection between the base and the adapter unit is achieved through the magnetic connection of the first and second magnetic components, which facilitates quick installation or removal of the diffuser; 4) The adapter unit can be freely connected to the light source and / or photographic equipment, which is highly flexible in use and has a simple installation structure that is easy to process; 5) A diffuser plate can be detachably connected to the diffuser surface to further diffuse the light in all directions, making the light diffusion range wider and the light more uniform.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0034] like Figures 1-5 As shown, a softbox includes a base 1, a reflector 2 disposed around the base 1, and an adapter unit 4. A through hole 11 is formed in the center of the base 1, through which the lens of a photographic device 5 can take pictures. The reflector 2 has a mounting port 21 for a light source 3 to extend into. The adapter unit 4 is used for detachably connecting the light source 3 and / or the photographic device 5. In other words, the adapter unit 4 can be detachably connected to the light source 3 alone, or the adapter unit 4 can be detachably connected to the photographic device 5 alone, or the adapter unit 4 can connect both the light source 3 and the photographic device 5 simultaneously.

[0035] The reflector 2 and the base 1 cooperate to form a diverging cavity 6. This diverging cavity 6 has at least a first reflective surface 61, a second reflective surface 62, and a diverging surface 63. The light emitted by the light source 3 is reflected at least by the first reflective surface 61 and the second reflective surface 62 before exiting from the diverging surface 63. Specifically, as... Figure 1 , Figure 2 , Figure 6 As shown, the reflector 2 is fitted around the base 1, and the two are fixedly connected by a nut passing through the threaded hole 14 on the reflector 2 and the base 1. The space formed by the inner wall of the reflector 2 and the outer wall of the base 1 is a diverging cavity 6. The light source 3 extends into the diverging cavity 6 of the reflector 2 through the mounting port 21. The light emitted by the light source 3 is reflected and diffused by the first reflective surface 61 to the second reflective surface 62. The second reflective surface 62 receives the light reflected by the first reflective surface 61 and performs a second reflection on the light, which is finally emitted from the diverging surface 63. After being reflected by the first reflective surface 61 and the second reflective surface 62, the direct light from the light source 3 is converted into soft diffused light, with a wider emission angle and softer light, preventing the direct light from shining on the object being photographed and producing a highlight. Here, the diverging surface 63 refers to the plane formed by the end of the reflector 2 away from the mounting port 21 and the outer end of the base 1, regardless of whether other devices are installed on this plane. In this embodiment, the light is reflected twice by the first reflective surface 61 and the second reflective surface 62. Of course, in other embodiments, multiple reflective surfaces can be provided in the diverging cavity 6 to reflect the light multiple times, resulting in a better soft light effect. No specific limitation is imposed.

[0036] like Figure 8 As shown, the reflector 2 includes an inner body 22 and an outer body 23. At least part of the outer wall of the inner body 22 is inclined outward from the center from the side where the mounting port 21 is located to the side where the radiating surface 63 is located, thereby forming a first reflective surface 61. At least part of the inner wall of the outer body 23 is inclined outward from the center from the side where the mounting port 21 is located to the side where the radiating surface 63 is located, thereby forming a second reflective surface 62.

[0037] Taking the direction shown in Figure 6 as an example, when an inner seat 22 is provided inside the reflector seat 2, the projection area of ​​the inner wall of the inner seat 22 onto the outer wall of the base 1 is S. At this time, the diverging cavity 6 specifically refers to the space remaining after subtracting the projection area S from the area between the inner wall of the reflector seat 2 and the outer wall of the base 1. The light reflection path is as follows: the light from the light source 3 shines directly to the left onto the first reflective surface 61 of the outer wall of the inner seat 22. After being reflected obliquely upward by the first reflective surface 61, the light is reflected onto the second reflective surface 62 of the inner wall of the outer seat 23. The second reflective surface 62 further reflects the light, and finally it is emitted from the diverging surface 62. The inner base 22 and the outer base 23 have different tilt angles, so that the light emitted from the light source 3 is reflected in sequence by the tilted first reflective surface 61 and the second reflective surface 62, and the light is tilted to different directions, which greatly increases the range of light illumination. Moreover, it can be concentrated and emitted towards the diverging surface 63 according to the set target route without weakening the intensity of the light. In addition, the axial projection area of ​​the inner base 22 is L1, and the axial projection area of ​​the light source 3 is L. L is completely within L1. That is to say, the outer wall of the inner base 22 can receive all the light from the light source 3, avoiding some of the light from the light source 3 from being emitted directly without reflection, which would cause uneven light intensity and affect the shooting effect.

[0038] In addition, in this embodiment, the surfaces of the inner base 22 and the outer base 23 are made of smooth reflective material, which makes the light softer after multiple reflections, and the light intensity is not weakened. Of course, in other embodiments, the inner base 22 and the outer base 23 can also be made of rough reflective material, and the light source 3 will cause diffuse reflection when it shines on the reflective surface, making the light reflection direction more dispersed and the soft light effect better. There is no specific limitation.

[0039] like Figure 9 , Figure 10 , Figure 12As shown, the adapter unit 4 includes at least a first magnetic member 41, a second magnetic member 42 that can be magnetically connected to the first magnetic member 41, and a fixing base 43 with a hollow center. The first magnetic member 41 and the second magnetic member 42 are respectively disposed on the base 1 and the fixing base 43. Specifically, the side of the base 1 facing the fixing base 43 is the back of the base 1, and the side of the fixing base 43 facing the base 1 is the front of the fixing base 43. The first magnetic member 41 is disposed on the annular end face of the back of the base 1, and the first magnetic member 41 includes multiple circumferentially spaced... The magnets in the distribution section, the second magnetic suction component 42 is a ring-shaped metal component, fixedly mounted on the front of the fixing base 43 and surrounding the outer periphery of the hollowed-out portion of the fixing base 43. The size of the ring-shaped metal component matches the size of the ring end face of the base 1 where the first magnetic suction component 41 is located, facilitating the connection between the first magnetic suction component 41 and the second magnetic suction component 42. At the same time, the ring-shaped metal component has a large adsorption area, eliminating the need for a one-to-one correspondence with the magnets in the first magnetic suction component 41 to achieve magnetic attraction connection, reducing alignment steps and simplifying installation. Through the magnetic attraction connection of the first magnetic suction component 41 and the second magnetic suction component 42, the magnetic attraction connection between the base 1 and the adapter unit 4 is achieved, facilitating the separation of the base 1 and the adapter unit 4.

[0040] Mount 43 is used for detachable connection of light source 3 and / or photographic equipment 5, such as... Figure 7 , Figures 10-12 As shown, the mounting base 43 has an adapter section 431 that can be detachably connected to the photographic equipment 5, and a snap-fit ​​part 432 that can be detachably connected to the light source 3. Specifically, the adapter section 431 is an annular protrusion located on the back of the mounting base 43. The surface of the annular protrusion has external threads, and the lens end of the photographic equipment 5 has internal threads. When using the photographic equipment 5, the internal thread of the lens end of the photographic equipment 5 is threaded to the external thread of the adapter section 431, thereby realizing the assembly of the mounting base 43 and the photographic equipment 5. In addition, the hollow part of the mounting base 43 is connected to the through-hole. The hole 11 is directly opposite, allowing the photographic equipment 5 to shoot through the hollow part of the adapter unit 4 and the through hole 11 of the base 1, preventing the mounting base 43 from obstructing the lens. The locking part 432 is the outermost end of the mounting base 43. The back of the light source 3 has a locking groove 31, which is semi-circular with one end open. The locking part 432 slides into the locking groove 31 from the open end, realizing the assembly of the light source 3 and the mounting base 43. Disassembly is simple; just slide the locking part 432 out of the locking groove 31. The structure is simple and easy to assemble and disassemble. Users can choose to connect the mounting base 43 to the photographic equipment 5, or to the light source 3, or to both the photographic equipment 5 and the light source 3, depending on the actual situation, making it flexible to use.

[0041] like Figure 6As shown, the base 1 is at least partially flared and conical. The inner diameter of the flared and conical part gradually increases from the side where the light source 3 is located to the side where the diverging surface 63 is located. The axial projection of the flared and conical part coincides with the axial projection of the light source 3. Specifically, the axial projection area of ​​the flared and conical part is L2, and the axial projection area of ​​the light source 3 is L. L2 and L partially coincide, so that the base 1 blocks part of the strong light from the light source 3, reduces the light intensity, and avoids strong light from affecting the lens framing.

[0042] like Figure 4 , Figure 12 As shown, a diffuser plate 7 is arranged on the diverging surface 63, filling the space between the outer wall of the base 1 and the inner wall of the reflector 2. Magnets 81 and 82, which can attract each other, are provided between the diffuser plate 7 and the reflector 2. Specifically, magnet 81 is located at the four corners of the diffuser plate 7, and magnets 82 are located at the four corners of the reflector 2 facing the diverging surface 63. The positions of magnets 81 and 82 correspond, and the diffuser plate 7 and reflector 2 are detachably connected by magnetic attraction, making assembly and disassembly convenient. When the diffuser plate 7 is installed, light is reflected by the second reflector 62 onto the diffuser plate 7 and further diffused in all directions through the diffuser plate 7, resulting in a wider light diffusion range, more uniform light, and higher softness. Furthermore, the diffuser plate 7 has a hollow center, matching the opening size of the flared conical portion of the base 1. This not only prevents the diffuser plate 7 from obstructing the lens but also prevents light leakage from the connection between the diffuser plate 7 and the base 1, thus avoiding inconsistent light intensity and affecting the soft light effect.

[0043] This utility model also discloses a soft light system, including a light source 3, the aforementioned soft light cover, and a diffuser plate 7 disposed on the radiating surface 63. The light source 3 is detachably connected to the adapter unit 4. The base 1 includes a cylindrical section 12 and a flared conical section 13. The light source 3 is an annular light source, which is connected between the cylindrical section 12 and the mounting port 21. Specifically, the annular light source is sleeved on the cylindrical section 12 and extends into the radiating cavity 6 through the mounting port 21.

[0044] Assembly process of this utility model: The cylindrical segment 12 of the base 1 passes through the hollow part in the middle of the inner seat 22, and the base 1 is fixedly connected to the reflector seat 2 by a nut (to... Figure 1 (For example); slide the snap-fit ​​part 432 into the snap-fit ​​slot 31 to connect the adapter unit 4 and the light source 3, and then thread the adapter section 431 to the photographic equipment 5 (for example); Figure 3 (For example), the light source 3 is then inserted into the mounting port 21, placing it between the cylindrical section 12 and the mounting port 21. The diffuser is then connected to the photographic equipment 5 and the light source 3 simultaneously via the magnetic attraction of the first magnetic member 41 and the second magnetic member 42. Finally, the diffuser plate 7 is attached to the reflector base 2 via magnet 1 81 and magnet 2 82. Figure 4 (For example).

[0045] like Figure 6 As shown, during use, the light emitted from the light source 3 is reflected by the first reflective surface 61 onto the second reflective surface. The second reflective surface 62 further reflects the light onto the diffuser plate 7, and finally diffuses the light through the diffuser plate 7, increasing the diffusion range and making the light softer. After use, the diffuser can be directly removed from the light source 3, making it convenient to use and easy to assemble and disassemble.

[0046] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
