Description

Technical Field

[0001] The utility model relates to the technical field of photographic and video shooting equipment, in particular to a soft light screen and a soft light component. Background Art

[0002] With the rise of self-media and short videos, people have more and more demands for photography and video shooting. In order to fully present personalized creations, users' demands for the performance of shooting equipment are also becoming more and more diverse. Photography and videography are closely related to light. In today's video shooting scenarios, in order to make the light irradiated on the person or object being photographed softer, it is generally necessary to place a soft light device between the photographic light and the person or object being photographed, so that the light emitted by the photographic light is scattered by the soft light device and then irradiated on the person or object being photographed. Common ones include soft light umbrellas, soft light boxes, soft light boards, etc. Different types of soft light devices can meet the light requirements for different shooting objects in different indoor, studio, outdoor and other scenarios.

[0003] For a soft light board, a common structure is that a white soft light cloth is fixed inside a steel ring, and the light passes through the soft light cloth to achieve the soft light effect. On the one hand, the steel ring has a certain hardness to keep the soft light cloth in a flat and open state. On the other hand, the steel ring can be bent, so that the soft light board can be folded and stored after use. Usually, such a soft light board needs to be held by a staff member other than the photographer, or the soft light board is clamped and fixed at both ends by using a tripod and clips in a photography studio. However, this fixing method easily leads to a large difference in the force on the soft light board. In the area near the connection line of the clamping points, the soft light cloth is in a flat state under the balanced pulling force at both ends. However, in the area far from this area, especially at the top, due to the self-gravity of the steel ring, the soft light cloth is prone to local warping to the left or right, making this part of the area of the soft light cloth not in the same plane as the area near the connection line of the clamping points, affecting the soft light performance after the light source penetrates the soft light cloth. In addition, the clips cause certain damage to the soft light cloth, affecting the service life of the soft light cloth. Summary of the Utility Model

[0048] Typical implementation modes reflecting the features and advantages of the present utility model will be described in detail in the following description. It should be understood that the present utility model can have various changes in different implementation modes, all of which do not depart from the scope of the present utility model, and the descriptions and illustrations therein are essentially for illustrative purposes and not for limiting the present utility model.

[0049] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indication of the direction or position relationship (such as up, down, left, right, front and back, etc.) is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. When these elements are in the positions shown in the drawings, these descriptions are appropriate. If the description of the positions of these elements changes, then the indication of these directions also changes accordingly.

[0050] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0051] Each embodiment of the present application provides a soft light screen and a soft light component including the soft light screen. The soft light component includes a soft light screen and a fixing frame, and the soft light screen is detachably connected to the fixing frame. Among them, the soft light screen includes a soft light area and a border area surrounding the soft light area. The border area is provided with a first connection unit, and the fixing frame is provided with a corresponding second connection unit. The first connection unit is detachably connected to the second connection unit.

[0052] Please refer to Figure 1 Figure 2 , Figure 1 is a schematic structural diagram of a soft light component 1 according to an embodiment of the present application, Figure 2 is Figure 1 a schematic exploded view of the soft light component 1 shown. The soft light component 1 includes a soft light screen 11 and a fixing frame 13, and the soft light screen 11 is detachably connected to the fixing frame 13. The soft light screen 11 includes a soft light area 111 and a border area 110. The border area 110 surrounds the soft light area 111. Light emitted by a light source (not shown in the figure) can obtain soft light after passing through the soft light area 111.

[0053] Please also refer to Figure 3 which is Figure 2 an enlarged schematic view of part A of the soft light component 1 shown. The border area 110 is provided with a first connection unit 113, and the fixing frame 13 is provided with a corresponding second connection unit 136. The first connection unit 113 is detachably connected to the second connection unit 136. As an example, the contour of the fixing frame 13 is substantially the same as the contour of the soft light screen 11, and the contour formed by the first connection unit 113 is substantially the same as the soft light screen 11. As shown in the figure, for example, the soft light screen 11 is a rectangular structure, and the fixing frame 13 is also a rectangular structure, and the aspect ratios of the two are substantially the same. The first connection unit 113 can be a continuous integral structure or a plurality of discrete components. In some embodiments, the second connection unit 316 is disposed on the surface of the fixing frame 13 facing the light incident surface or the light exiting surface of the soft light screen 11. The soft light screen 11 is connected to the fixing frame 13 face to face through the first connection unit 113 located in the border area 110, that is, the light incident surface side is butted against the front surface of the fixing frame 13. Thus, when installing the soft light screen 11 onto the fixing frame 13 or disassembling the soft light screen 11 from the fixing frame 13, the user can complete the operation on one side of the soft light screen 11, which is convenient and easy to use.

[0054] In some embodiments, the fixing frame 13 is a foldable frame. Please refer to Figure 1 , Figure 3 and Figure 4 as well, where Figure 4 is Figure 1 a schematic structural view of the folded state of the fixing frame 13 of the soft light component 1 shown. The fixing frame 13 includes a plurality of fixing rods 130, and the fixing rods 130 are connected by joints. As an example, the fixing frame 13 includes a first connecting joint 132 and a second connecting joint 134. The first connecting joint 132 is used to connect adjacent fixing rods 130 at the corners, and the second connecting joint 134 is used to connect two adjacent fixing rods 130 on the same axis. It should be understood that the coaxial connection here means that the long axes of the fixing rods 130 are in the same direction. The fixing rods 130 can be connected end to end through the first connecting joint 132 and the second connecting joint 134, so that the fixing frame 13 can be conveniently switched between the unfolded state and the folded state as needed. When the fixing frame 13 is in the unfolded state, it forms a stable frame and can adapt to the contour of the soft light screen 11. By arranging a face-to-face connection between the first connecting unit 113 and the fixing frame 13 in the edge area surrounding the soft light area 111, the force on the soft light screen 11 can be made more uniform. Especially when the soft light screen 11 uses a flexible substrate, the soft light screen 11 can be unfolded and fixed on the fixing frame 13 flatly, reducing the structural damage to the soft light screen 11 and improving the soft light effect, reliability and service life of the product. And the fixing frame 13 can be folded and stored, which can reduce the space occupied by the fixing frame 13 during transportation and greatly reduce the transportation cost. As an example, for two adjacent fixing rods 130 connected by the first connecting joint 132, the rotation angle of the joint is 90 degrees, and for two adjacent fixing rods 130 connected by the second connecting joint 134, the rotation angle of the joint is 180 degrees (approximate), so that the fixing rods of the folded fixing frame 13 can be close to each other and the gap between the rods can be minimized, so that the space occupied by the folded and stored fixing frame is smaller.

[0055] A second connecting unit 136 is provided on the surface of the fixing rod 130 facing the light incident surface (or light exit surface) of the soft light screen 11. As an example, the second connecting unit 136 is a magic tape. Correspondingly, the first connecting unit 113 includes a magic tape. When the magic tape of the first connecting unit 113 is the male surface, the magic tape of the second connecting unit 136 is the matching female surface, and vice versa. The male surface and the female surface can be loop and hook respectively, which will not be described in detail here.

[0056] Please further refer to Figure 5, which is Figure 1Schematic exploded view of the diffuser screen 11 of the soft light component 1 shown. In some embodiments, the diffuser screen 11 may be an electronically controlled atomization film, and its soft light area 111 includes a thin film component 1110 of a composite structure. The thin film component 1110 may include two opposite substrates and a dimming layer located between the substrates, and the substrates are light-transmitting substrates. As an example, the thin film component 1110 may include two glass substrates or two PET substrates, with one or more thin film materials sandwiched between the substrates, and liquid crystal molecules as the dimming layer. The thin film material may be a transparent ITO electrode thin film. The substrate may extend to the edge wrapping area 110, and a first electrode 1112 and a second electrode 1114 serving as positive and negative electrodes are also provided in the edge wrapping area 110. The first electrode 1112 and the second electrode 1114 are respectively used to connect the positive and negative poles of the power supply and connect the conductive thin film to apply a voltage to the dimming layer. The electronically controlled atomization film can change its atomization degree through an alternating voltage, and its principle is mainly based on the electrochromic effect and the arrangement change of liquid crystal molecules under the action of an electric field to change its atomization degree. As an example, the substrate extends to the edge wrapping area, the first electrode and the second electrode are fixed on the substrate, and the dimming layer can be blocked by a insulating material between the extended area of the substrate and the soft light area to prevent liquid leakage when sewing the edge wrapping material. As another example, in addition to liquid crystal molecules such liquid crystals that can be used as the dimming layer, other forms and types of dimming layers can also be used in this application, such as liquid or solid dimming layers. The substrates included can also adopt a single-layer substrate structure in addition to a pair of upper and lower substrates.

[0057] The power interface circuit mainly includes a connection cable 115 and a power interface 150. One end of the connection cable 115 is connected to the conductive thin film, and the other end is connected to the power interface 150. The power interface 150 is used to connect an external power supply, a control box and other power supply or signal transmission control units to obtain control signals such as power supply and atomization degree adjustment signals from the external power supply and the control box. It should be understood that the connection cable 115 includes various forms of conductive circuit structures such as cables, printed circuits, gold wires, and wires.

[0058] When the diffuser screen 11 is powered off, the liquid crystal molecules therein will be randomly arranged, causing light to scatter in all directions, making the glass present a frosted or milky white opaque state. When powered on, the liquid crystal molecules will be arranged in a direction perpendicular to the substrate, enabling light to pass through smoothly, thus making the glass present a transparent state. This conversion between the transparent and opaque states can be completed instantly, realizing the atomization and clarity effects of the glass. By changing the voltage input between the first electrode 1112 and the second electrode 1114, the atomization degree of the diffuser screen 11 can be changed, and further the light transmittance of the diffuser screen 11 can be changed, and the light rays passing through the soft light area 111 from the light incident surface (not marked) of the diffuser screen 11 and exiting from the light exit surface 111' can obtain different soft light effects. It should be understood that the light exit surface 111' and the light incident surface in the figure are opposite sides and can be interchanged without affecting the use effect.

[0059] In some embodiments, the edge-wrapping region may be coated with an edge-wrapping layer, which can cover the first electrode 1112 and the second electrode 1114, protecting the electrodes. Additionally, it can serve as a carrier substrate for the first connection unit 113, enabling the first connection unit 113 to be decoupled from the thin-film component 1110 and reducing damage to the thin-film component. All or part of the connection cable 115 can also be covered by the edge-wrapping layer, while the power interface 150 is exposed. The edge-wrapping layer can be a flexible material such as cloth or a material with a light-shielding function. The edge-wrapping layer can be a single-layer structure or a multi-layer structure. For example, the edge-wrapping layer can be a single layer, with one side covering the electrodes and the other side sewn with Velcro.

[0060] In some embodiments, the soft light screen 11 is a flexible screen. For example, the thin-film component 1110 is a flexible thin film. Specifically, the thin-film component 1110 can use a flexible substrate, on which a transparent conductive film is coated, and liquid crystal molecules are added between two layers of flexible substrates to form the flexible thin-film component 1110. In one example, the soft light screen 11 is a flexible screen, and the fixing frame 13 is a foldable frame. When storing, the soft light screen 11 can be curled up for storage because the curling method is not likely to produce creases and the occupied space after curling is small. After the fixing frame 13 is folded, the requirements for transportation and storage space are significantly reduced, enabling the soft light component 1 to reduce the space occupied by the fixing frame 13 during transportation and greatly reducing the transportation cost. When both are unfolded, they can be quickly connected and fixed through the corresponding first connection unit 113 and second connection unit 136, obtaining a reliable soft light effect, reducing equipment damage, and extending the service life of the equipment.

[0061] Please refer to Figure 5 , as an example of the present application, the soft light screen 11 includes a thin-film component 1110, a first electrode 1112, a second electrode 1114, a connection cable 115, a power interface 150, a first edge-wrapping member 1131, and a second edge-wrapping member 1132. The first electrode 1112 and the second electrode 1114 serve as the positive and negative electrodes respectively to provide an external voltage signal to the thin-film component 1110. The first electrode 1112 and the second electrode 1114 are connected through the connection cable 115 and the power interface 150, and obtain the external voltage signal through the power interface 150. The first edge-wrapping member 1131 and the second edge-wrapping member 1132 are fixed to the edge regions of the opposite light-emitting surface and light-incident surface of the thin-film component 1110 and the side surface of the thin-film component 1110 to form an edge-wrapping layer covering the edge-wrapping region 110. The first electrode 1112, the second electrode 1114, and at least a part of the cable or circuit are covered by the first edge-wrapping member 1131 and the second edge-wrapping member 1132, and the power interface 150 is exposed outside the edge-wrapping region 110. It should be understood that the side edge of the thin-film component 1110 is located between the light-incident surface and the light-emitting surface.

[0062] The first edge-binding member 1131 and the second edge-binding member 1132 are respectively located at the edge regions of the opposite upper surface and lower surface of the film assembly 1110. The first edge-binding member 1131 and the second edge-binding member 1132 can be two separate parts, which are combined into one body by various methods such as stitching, bonding, and pressing, and are wrapped around the edges and sides of the upper and lower surfaces of the film assembly 1110; the first edge-binding member 1131 and the second edge-binding member 1132 can also be an integral structure, which is wrapped around the edges and sides of the upper and lower surfaces of the film assembly 1110 by means such as stitching, pasting, and pressing. Both the first edge-binding member 1131 and the second edge-binding member 1132 are Velcro. The surface of the first edge-binding member 1131 is the male surface, and the surface of the second edge-binding member 1132 is the female surface. In this way, one of the surfaces can be flexibly selected for docking and fixing according to the structure of the second connection unit 136 on the fixing frame 13. Of course, in some other embodiments, one of the first edge-binding member 1131 and the second edge-binding member 1132 may not have Velcro, but only be an edge-binding layer such as cloth.

[0063] The contour of the fixing frame 13 is substantially the same as the contour of the soft light screen 11, and the contour formed by the first connection unit 113 is substantially the same as the contour of the soft light screen 11. As shown in the figure, for example, the soft light screen 11 is a rectangular structure, and the fixing frame 13 is also a rectangular structure, and the length-width ratios of the two are substantially the same.

[0064] Please further refer to Figure 6 which is Figure 5 an exploded structural schematic diagram of a deformation implementation manner of the soft light screen shown. Figure 6 The soft light screen 11' shown is substantially the same as the soft light screen 11 shown in Figure 5 . The main difference is that the first edge-binding member 1131' and the second edge-binding member 1132' are respectively edge-binding layers. Several first Velcros 1135 are fixed on the surface of the first edge-binding member 1131', and several second Velcros 1136 are fixed on the surface of the second edge-binding member 1132'. Several first Velcros 1135 and / or several second Velcros 1136 form the first connection unit 113. The several first Velcros 1135 are distributed at intervals in the edge-binding area 110. For example, 2 to 3 Velcros are fixed on each edge of the edge-binding area 110, and the Velcros on each edge substantially form a rectangular enclosing area. The first Velcro 1135 and the second Velcro 1136 face in opposite directions. Compared with the first connection unit 113 that forms a continuous closed shape in the edge-binding area 110, the first connection unit 113 in this example is discretely distributed, but the formed contour is still substantially the same as the contour of the soft light screen 11. Therefore, when the soft light screen 11 is fixed to the fixing frame 13, "face-to-face" docking occurs between the two in the edge-binding area 110, so that the soft light screen 11 is evenly stressed and the soft light area 111 can remain flat.

[0065] Please refer to Figure 7Yes, it is a schematic exploded view of the flexible light screen 21 according to another embodiment of the present application. The flexible light screen 21 includes a thin film assembly 2110, a first electrode 2112, a second electrode 2114, a connection cable 215, a power interface 250, a first edge wrapping member 2131, and a second edge wrapping member 2132. The first electrode 2112 and the second electrode 2114 serve as positive and negative electrodes respectively to provide an external voltage signal to the thin film assembly 2110. The first electrode 2112 and the second electrode 2114 are connected through the connection cable 215 and the power interface 250, and obtain the external voltage signal through the power interface 250. The first edge wrapping member 2131 and the second edge wrapping member 2132 are fixed to the edge regions and the side edges of the light-emitting surface and the light-incident surface of the thin film assembly 2110 opposite to each other to form an edge wrapping layer covering the edge wrapping region. The first electrode 2112, the second electrode 2114, and at least a part of the cable or circuit are covered by the first edge wrapping member 2131 and the second edge wrapping member 2132, and the power interface 250 is exposed outside the edge wrapping region.

[0066] Several first through holes 2135 are provided on the surface of the first edge wrapping member 2131, several second through holes 2136 are provided on the surface of the second edge wrapping member 2132, and several third through holes 2115 are provided on the edge of the thin film assembly 2110. The several first through holes 2135, the several third through holes 2115, and the several second through holes 2136 are aligned in sequence along the direction perpendicular to the light-emitting surface of the flexible light screen 21 and form several rope-passing holes. The rope-passing holes serve as the first connection unit of the flexible light screen 21. By threading a fixing rope through the rope-passing holes and fixing the flexible light screen 21 to the fixing frame through the fixing rope.

[0072] Please refer to Figure 12 and Figure 13 , where Figure 12 is a schematic structural view of the first perspective of another soft light screen 51 of the present application, Figure 13 is Figure 12The structural diagram of the second viewing angle of the soft light screen 51 is shown, and the two viewing angles correspond to the front and back of the screen respectively. The connection structure with the fixed frame adopted by the soft light screen in the aforementioned embodiments and examples is applicable to the soft light screen 51 described in this example, so the relevant detailed structure is not repeated here. The main difference between the soft light screen 51 in this example and the aforementioned light-transmitting screens is that the soft light screen 51 is integrated with a control box 517. The soft light screen 51 includes a thin film component 5110 and a first electrode 5112 and a second electrode 5114 located in the edge area of ​​the thin film component 5110. The control box 517 is connected to the first electrode 5112 and the second electrode 5114 through a line. The control box 517 is fixed on the surface of the thin film component 5110 and is located in the corner area.

[0073] The control box 517 includes a housing and functional circuits such as a control circuit, a power circuit, a battery, and a wireless transmission module located inside the housing. The control circuit is connected to the first electrode 5112, the second electrode 5114, the wireless transmission module, the power circuit, and other modules. The control box 517 also includes a display screen 5170 and a button 5172 connected to the control circuit. The soft light area 511 of the soft light screen 51 can be adjusted for atomization and transmittance through the control box 517 provided by the soft light screen to change the soft light effect. The control circuit in the control box 517 receives the adjustment signal input by the user through buttons, knobs, and external devices, and outputs the corresponding working voltage according to the adjustment signal. The film component 5110 displays the corresponding atomization according to the voltage value of its working voltage to change the transmittance of the soft light area 511. Through the wireless transmission module in the control box 517, the control box 517 can be connected to external devices such as remote controls, consoles, mobile phones, etc., so that the soft light effect of the soft light screen 51 can be conveniently and quickly adjusted through external devices. It can also be connected to a mobile phone APP to realize visual dimming operation through the APP operation interface, making the operation more intuitive and improving the user experience. The button 5172 can also be an adjustment operation structure such as a knob or a lever. The control box 517 can also include a power interface to connect to an external power supply device for direct power supply or charging of the battery.

[0074] The edge area (including the front and back edges and the side surfaces) of the film assembly 5110 can be covered with an edge layer to cover and protect the electrical structures such as the electrodes and circuits. Furthermore, the edge area can be further filled with waterproof glue or a waterproof strip can be affixed to waterproof and isolate the circuits and electrodes. A first connecting unit 513 is provided in the outer edge area of ​​the soft light area 511. The first connecting unit 513 can use Velcro to detachably mount the soft light screen 51 to the fixed frame.

[0075] In summary, the present application provides a soft light screen and a soft light component. The soft light screen includes a soft light area, a border area, a first electrode, a second electrode, and a first connection unit. A light dimming layer is provided in the soft light area. The border area surrounds the soft light area, and a border layer is coated on the border area. The first electrode and the second electrode are connected to both ends of the light dimming layer and are used to apply an electrical signal to the light dimming layer. The first connection unit is disposed in the border area, and the first connection unit is adapted to be fixed to a fixed frame, wherein the fixed frame is provided with a second connection unit, and the first connection unit is detachably connected to the second connection unit in a corresponding manner. By applying a voltage and current signal to the light dimming layer through the electrodes, the light transmittance presented by the light dimming layer can be changed to obtain an adjustable light transmission effect. And by providing a first connection unit in the border area that can be connected and installed to the fixed frame, the soft light area of the soft light screen can be surrounded by the first connection unit. Thus, when the soft light screen is detachably connected to the fixed frame through the first connection unit, the soft light area receives balanced connection forces on its periphery, enabling the soft light area to maintain a flat state, reducing damage to the soft light screen by external installation and fixing mechanisms, and improving its soft light performance and service life. In addition, the detachable connection enables convenient and reliable operation during use, facilitating storage and transportation.

[0076] As a further supplement to the embodiments of the present application, in addition to being installed on a dedicated fixed frame or bracket, the soft light screen can also be quickly installed using the existing frame structure at the shooting site. For example, a soft light screen with a magnetic structure in the border area can be installed on a ceiling-mounted metal frame and corresponding to the installed cloth lights and panel lights above it. On the other hand, the soft light screen can be a color atomization adjustable screen, including but not limited to coating a color coating on the inner and outer surfaces of the substrate in the film component, or adding a color filter layer between the substrates, or injecting dyes and color-developing materials into the middle light dimming layer to form a soft light screen with a colored light atomization effect.
