[0002] In today's era of rapid internet development, creating content such as sharing life information on social media has become a daily necessity for modern people, enriching their social lives by recording and sharing their experiences. Among the types of information shared, taking pictures or videos is one of the most common methods, using images to present life experiences. However, most people may not have professional photography equipment and usually only use their mobile phones, making it difficult to elevate their photography to a professional level. For example, mobile phones typically do not have comprehensive lighting functions, resulting in poor results when photographing three-dimensional objects, especially those with concave or convex structures, such as food. Furthermore, lighting setups require certain knowledge and skills in lighting design. Even if users assemble their own light sources, maintaining the stability of the angle between the camera and the light source is necessary to achieve high-quality photographic results after lighting. All these considerations increase the workload for users who need to improve their photographic quality. Utility Model Content

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] It should be noted that the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to direct setup or connection, or indirect setup or connection through centered components or centered structures.

[0037] Furthermore, in embodiments of this utility model, terms such as "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are used to indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, or in a conventional placement or usage state. These terms are merely for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the structure, feature, device, or element referred to must have a specific orientation or positional relationship, nor that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0038] The various specific technical features and embodiments described in the detailed embodiments can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / embodiments in this utility model will not be described separately.

[0039] like Figures 1 to 6 As shown in the figure, an embodiment of this utility model provides a supplementary lighting device 100, including a light stand body 10, a floodlight 2, and a spotlight 3. The floodlight 2 and / or the spotlight 3 are connected to the light stand body 10 through a direction adjustment structure. The floodlight 2 is mainly used to emit soft light to supplement the lighting of a large area being photographed; the spotlight 3 is mainly used to emit hard light to provide focused lighting for key areas being photographed. The floodlight 2 and / or the spotlight 3 can adjust their positions on the light stand body 10 and adjust the angle of the emitted light through the direction adjustment structure to cooperate with each other during photography.

[0040] By implementing the above scheme, spotlight 3 and floodlight 2 are simultaneously mounted on the main body 10 of the light stand. This allows the floodlight 2 to provide a broad, soft light to the environment, while the spotlight 3 provides supplemental hard light to the subject from a specific angle. For example, when illuminating uneven objects, the floodlight 2, even with its soft light from a single angle, may not be able to fully illuminate certain areas, affecting the photographic effect. In this case, the spotlight 3 is used to supplement the lighting and complete the illumination of the object. Alternatively, when it is necessary to illuminate a certain part of the object with more light than other parts, the spotlight 3 can be used again for focused illumination while the floodlight 2 provides soft light. The supplemental lighting device 100 caters to both the need for supplemental lighting over a large area and the need for supplemental lighting in key areas during shooting, thus improving its practicality.

[0041] In some embodiments, the light stand body 10 includes a first light stand 1 and a second light stand 31. The floodlight 2 is connected to the first light stand 1, and the spotlight 3 is connected to the first light stand 1 via the second light stand 31. The first light stand 1 supports the floodlight 2 to a specific position; and the second light stand 31 extends out of the first light stand 1 and supports the spotlight 3. The position of the spotlight 3 is set by setting the structural shape of the second light stand 31, thereby adjusting the angle at which the spotlight 3 emits hard light onto the subject / area being photographed.

[0042] Specifically, the second light holder 31 is a long, adjustable support, such as a multi-link mechanism or a metal flexible tube connected by friction damping, which allows for easy adjustment of the shape of the second light holder 31 while still supporting the spotlight 3, thereby adjusting the angle at which the spotlight 3 emits hard light. It can be understood that the second light holder 31 is the direction adjustment structure connected to the spotlight 3.

[0043] By implementing the above scheme, the relative incident angles of the floodlight 2 and the spotlight 3 are adjustable, making the use of the supplementary lighting device 100 more convenient.

[0044] In some embodiments, a connector 23 is provided at the first end of the first lamp holder 1 near the first end of the floodlight 2. The connector 23 is adjustablely tilted and rotatably connected to the first end of the first lamp holder 1, and the floodlight 2 is adjustablely rotatably connected to the connector 23 via a rotating member 22. At the first end of the first lamp holder 1, the first lamp holder 1 is connected to the connector 23, and the connector 23 is then connected to the floodlight 2 via the rotating member 22. The connector 23 is used to allow the floodlight 2 to tilt and rotate relative to the first lamp holder 1, and the rotating member 22 is used to allow the floodlight 2 to rotate left and right relative to the first lamp holder 1, thereby allowing the incident angle of the floodlight 2 to be flexibly adjusted.

[0045] Specifically, one end of the connector 23 is connected to the first lamp holder 1 via a rotating shaft structure; the rotating member 22 is connected to the connector 23 on the other end face of the connector 23. Specifically, this connection can be a rotatable snap-fit ​​that allows the two end faces of the rotating member 22 and the connector 23 to rotate relative to each other. This application does not limit the method of implementing the adjustable left-right rotation connection of the rotating member 22 relative to the connector 23. It is understood that the rotating member 22 and the connector 23 form the direction adjustment structure connected to the floodlight 2.

[0046] In some embodiments, one end of the second lamp holder 31 is fixedly connected to or detachably connected to the first lamp holder 1, and the other end of the second lamp holder 31 is fixedly connected to the spotlight 3. The second lamp holder 31 is used to provide the spotlight 3 to the first lamp holder 1 and fix the spotlight 3 at a specific position on the first lamp holder 1. Depending on the user's needs, the spotlight 3 and the second lamp holder 31 supporting it may no longer need to be set on the first lamp holder 1. By making one end of the second lamp holder 31 detachably connected to the first lamp holder 1, the second lamp holder 31 can be removed from the first lamp holder 1 when the spotlight 3 is not needed, making it convenient for the user to adjust the structure of the supplementary lighting device 100.

[0047] Specifically, the connection method of the second lamp holder 31 to one end of the first lamp holder 1 can be snap-fit, binding, screwing in with bolts, etc., and this application does not limit it in this way.

[0048] In some embodiments, the second lamp holder 31 is disposed on one side of the first lamp holder 1, and the second lamp holder 31 is connected to one or at least two of the spotlights 3;

[0049] Alternatively, the second lamp holder 31 is provided on opposite sides of the first lamp holder 1, and the second lamp holder 31 is connected to one or at least two spotlights 3;

[0050] Alternatively, at least three second lamp holders 31 are provided on the side of the first lamp holder 1, and the second lamp holder 31 is connected to one or at least two of the spotlights 3.

[0051] When setting up the supplementary lighting device 100, installing only one second light stand 31 is convenient. However, sometimes multiple hard lights may be needed to enter the shooting environment from different angles. In this case, at least two spotlights 3 are connected to one second light stand 31. Each spotlight 3 on the second light stand 31 is distributed at a different location on the second light stand 31. Based on the shape of the second light stand 31, the incident position of each spotlight 3 is different, thus providing different incident angles. During shooting, if it is desired that the incident angle of the hard light more completely covers the subject for the purpose of supplementary lighting, the second light stands 31 are set at least on opposite sides of the first light stand 1 to ensure that the incident angle of the hard light completely surrounds the subject. In some cases, the first light stand 1 can also be fixedly connected to three or more second light stands 31 to increase the number of hard light incident angles / light sources. This can be flexibly adjusted according to user needs to improve the practicality of the supplementary lighting device 100.

[0052] In some embodiments, the spotlight 3 is screwed into a focusing tube 32, which contains a lens. The focusing tube 32 is used to adjust the distance between the light source of the spotlight 3 and the lens. As a separable component, the focusing tube 32 is screwed into the light outlet of the spotlight 3 via a thread. During the screwing process, the distance between the lens inside the focusing tube 32 and the light source of the spotlight 3 changes depending on the depth of screwing. This allows the light source of the spotlight 3 to be focused when it passes through the focusing tube 32 due to its distance from the lens. Therefore, the user can focus the spotlight 3 by controlling the degree to which the focusing tube 32 is screwed into the spotlight 3.

[0053] Understandably, a spotlight 3 can be equipped with different focusing tubes 32 to meet different focusing needs.

[0054] In some embodiments, the floodlight 2 is annular and includes a clamping portion 21. The clamping portion 21 includes a main stem 211 and a placement portion 212. The main stem 211 is connected to the floodlight 2, and the placement portion 212 is connected to the main stem 211. The placement portion 212 is located at or near the center of the floodlight 2. On opposite sides of the placement portion 212 are push-tightening members 2121 connected to the placement portion 212 and capable of approaching each other. The push-tightening members 2121 are used to clamp the two sides of a camera device on the placement portion 212. Within the annular floodlight 2, one end of the main stem 211 of the clamping portion 21 is fixedly connected to the inner ring of the floodlight 2, and the other end of the main stem 211 supports the placement portion 212 at or near the center of the floodlight 2. Specifically, the floodlight 2 is a circular light source on the light stand, and the placement part 212 is the location for placing photographic equipment (such as a mobile phone). The floodlight 2 surrounds the placement part 212 and thus surrounds the photographic equipment, thereby uniformly emitting soft light to the environment around the placement part 212. The pushers 2121 provided on opposite sides of the placement part 212 can clamp items by sliding and moving closer to each other, and different sizes of items can be clamped in the placement part 212 by varying the degree of their proximity.

[0055] Specifically, an elastic element is provided between the pusher 2121 and the placement portion 212 to prevent the pusher 2121 from sliding away from the placement portion 212. When an item needs to be placed on the placement portion 212, if the distance between the opposite sides of the item is greater than the distance between the pushers 2121, the elastic element is opened to allow the item to be placed in, and then the pushers 2121 clamp the item between the two pushers 2121 due to the restoring force of the elastic element. This application is not limited to the component that provides the restoring force for the pusher 2121; it can be a spring or any elastic and restoring element that can be easily conceived by those skilled in the art. Alternatively, even without the restoring force between the pushers 2121, depending on the specific shape of the item, such as if the distance between the pushers 2121 is less than the width corresponding to the clamped item, it is possible to prevent the clamped item from falling to the ground or shaking, thereby clamping the item.

[0056] Specifically, the placement part 212 and the main body 211 can be connected by a pivot structure, allowing the placement part 212 to tilt and rotate on the main body 211, further facilitating the user to adjust the angle of the photographic equipment mounted on the clamping part 21.

[0057] By implementing the above solution, it is more convenient to clamp photographic equipment onto the supplementary lighting device 100 and provide supplementary lighting to it.

[0058] In some embodiments, the first lamp holder 1 includes a fixing member 12 and a frame 11. At least two frame bodies 11 are provided, and both ends of the frame body 11 are connected to the fixing member 12. Adjacent frame bodies 11 are connected through the same fixing member 12.

[0059] The frame 11 includes two arm bars 111, and both ends of each arm bar 111 are rotatably connected to the fixed frame member 12 through a pivot structure, so that one frame 11 and two fixed frame members 12 connected to the frame 11 form a four-bar linkage mechanism.

[0060] The fixing member 12 includes connecting plates 121 spaced apart. The end of the arm bar 111 is clamped between the two connecting plates 121. The rotating shaft structure includes a connecting shaft 122. The connecting shaft 122 passes sequentially through one of the connecting plates 121, the end of the arm bar 111, and the other connecting plate 121. The first end and the second end of the connecting shaft 122 extend out of the connecting plate 121. The first end and / or the second end of the connecting shaft 122 have threads and are correspondingly provided with nuts 123. The nuts 123 are screwed into the first end and / or the second end of the connecting shaft 122 and press against the connecting plate 121, so that the two connecting plates 121 are clamped towards each other at the end of the arm bar 111.

[0061] Includes a hand-tightening handle 4, which is fixedly connected to the nut 123 on the connecting shaft 122. The hand-tightening handle 4 is used to adjust the tightness of the nut 123 on the connecting shaft 122.

[0062] Each frame 11 has two arm bars 111 connected to two corresponding fixed members 12 via a pivot structure. Specifically, the extension directions of the two arm bars 111 of a frame 11 are parallel to each other. One arm bar 111 of a frame 11 is connected to two fixed members 12, specifically at the two connecting shafts 122 of each fixed member 12. Within a frame 11, the distance between the two connecting shafts 122 to which one arm bar 111 is connected is the same as the distance between the two connecting shafts 122 to which another arm bar 111 in the same frame 11 is connected. Among the two fixed members 12 connected by a frame 11, the distance between the two corresponding connecting shafts 122 on the fixed member 12 connected to the same frame 11 is the same. Thus, the four connecting shafts 122 form a deformable parallelogram four-bar linkage mechanism between the frame 11 and the two fixed members 12. Thus, when the parallel distance between the two arm bars 111 of a frame 11 shrinks / expands during movement, the angle between the straight line formed by the distance between the two connecting shafts 122 on the fixed member 12 of the frame 11 and the extension direction of the arm bar 111 will change. As a result, by moving the two arm bars 111 of the frame 11, the fixed member 12 can be adjusted in orientation, thereby allowing the first lamp holder 1 of the supplementary lighting device 100 to be adjusted in shape.

[0063] In the contact between a frame 11 and a fixed member 12, a connecting shaft 122 passes sequentially through one connecting plate 121, the end of an arm 111, and another connecting plate 121. The first end and / or the second end of the connecting shaft 122, through threads and nuts 123, clamp the two connecting plates 121 together at the end of the arm 111, thereby preventing the connecting shaft 122 from detaching from the fixed member 12. Furthermore, the tightening of the nuts 123 on the two connecting plates 121 also restricts the rotation of the arm 111 on this shaft structure, thus fixing the shape of the first lamp holder 1. The connection between the frame 11 and the fixed member 12 is repeated in this manner to form the first lamp holder 1. Thus, the structure of the first lamp holder 1 is simple and easy to assemble.

[0064] Furthermore, at least one nut 123 of the connecting shaft 122 on at least one of the fixed members 12 is provided with a hand-tightening handle 4 for controlling the nut 123 of the connecting shaft 122, so that the user can adjust the rotation of the nut 123 by hand to tighten / loosen the structure of the connecting shaft 122 and adjust the shape of the first lamp holder 1.

[0065] At least one of the fixed members 12 is provided with a mounting tab 133, and a mounting post 132 is provided at the middle of one of the arm strips 111 connected to the fixed member 12. The first lamp holder 1 includes a spring 13. The mounting post 132 protrudes laterally from the arm strip 111, and the mounting tab 133 protrudes laterally from the fixed member 12 and has a hook-shaped portion 134. Hooks are provided at both ends of the spring 13. The spring 13 is mounted to the hook-shaped portion 134 and the mounting post 132 through the hooks. The spring 13 is used to maintain the upward swinging tendency of the arm strip 111 to which it is connected.

[0066] Please refer to the following: Figure 2 When the angle between the arm 111 with a mounting post 132 connected to a spring 13 and the frame 12 with a mounting tab 133 changes, the mounting post 132 on the arm 111 rotates around a connecting shaft 122 connected to the arm 111. The spring 13 mounted on the mounting post 132 is hooked onto the hook-shaped part 134 on the mounting tab 133 and rotates on the hook-shaped part 134, which is equivalent to taking the hook-shaped part 134 as the axis. When the frame 11 with the mounting post 132 connected to the spring 13 swings downward, the spring 13 is further stretched with the movement of the mounting post 132, so that the corresponding arm 111 has an upward force, which improves the load-bearing capacity of the first lamp holder 1. Both the mounting post 132 and the mounting tab 133 protrude laterally from the first lamp holder 1, because the protrusion ensures that there is space between them so that the spring 13 is not blocked by other structures of the first lamp holder 1 during installation.

[0067] Specifically, the spring 13 is attached to the mounting protrusion 132 and the hook-shaped part 134, and different springs 13 can be easily replaced to meet different restoring force / tension requirements.

[0068] In some embodiments, the first lamp holder 1 is fixedly connected to a mounting part 14, the mounting part 14 including a U-shaped mounting bracket 141 and a pressure member 142. The U-shaped mounting bracket 141 is provided with a locking threaded hole 1411 for the pressure member 142 to be inserted, and has a pressure-bearing end face 1412 on the opposite side of the locking threaded hole 1411. The pressure member 142 has a pressure-bearing end face 1421. The pressure member 142 is inserted into the U-shaped mounting bracket 141 through the locking threaded hole 1411. The pressure member 142 is used to rotate and control the distance between the pressure-bearing end face 1421 and the pressure-bearing end face 1412 of the U-shaped mounting bracket 141. When installing the first lamp holder 1 to a place, such as a tabletop, the pressure-bearing end face 1412 on the U-shaped bracket 141 of the mounting part 14 can be aligned with one side of the tabletop. Then, the pressure member 142 is rotated and inserted into the U-shaped bracket 141 through the locking thread hole 1411, so that the pressure-applying end face 1421 on the pressure member 142 approaches the pressure-bearing end face 1412. Finally, the pressure-applying end face 1421 is aligned with the other side of the tabletop that the pressure-bearing end face 1412 abuts. In this way, the pressure-applying end face 1421 and the pressure-bearing end face 1412 press against the tabletop and fix the relative position of the lamp holder and the tabletop.

[0069] Furthermore, the mounting part 14 is provided with a mounting groove 144 and a protrusion 145 that is slidably and rotatably disposed in the mounting groove 144. The mounting groove 144 opens upward, and the protrusion 145 is fixedly connected to the second end of the first lamp holder 1. The mounting part 14 also includes a second pressure member 143. The mounting groove 144 is provided with a threaded hole 1441 for the second pressure member 143 to be inserted into the groove. The second pressure member 143 is inserted into the mounting groove 144 through the threaded hole 1441 to contact the protrusion 145 and restrict the protrusion 145 from sliding or rotating in the mounting groove 144. When the user needs the first lamp holder 1 to have a higher height, the protruding part 145, which is fixedly connected to the first lamp holder 1 on the mounting part 14, is pulled out from the mounting groove 144. After being pulled out to the height required by the user and the protruding part 145 extends the length of the first lamp holder 1, the second pressure member 143 is rotated and inserted into the mounting groove 144 through the threaded hole 1441 in the groove, contacts the protruding part 145 and restricts the movement of the protruding part 145 in the mounting groove 144, thus completing the fixing of the protruding part 145. When the user needs to reduce the height of the lamp holder, the second pressure member 143 can be loosened from the threaded hole 1441 in the groove, so that the protruding member 145 no longer contacts the second pressure member 143, thus allowing it to slide or rotate freely in the mounting groove 144. After the protruding member 145 is housed in the mounting groove 144, the second pressure member 143 is inserted again from the threaded hole 1441 in the groove, contacting the protruding member 145 and restricting its sliding or rotation within the mounting groove 144, thus completing the fixation of the protruding member 145. When it is necessary to adjust the angle between the first lamp holder 1 and the mounting part 14, the protruding member 145 can also be rotated within the mounting groove 144 and fixed with the second pressure member 143. In this way, the use of the supplementary lighting device 100 is more flexible.

[0070] Specifically, in order to facilitate the sliding extension and rotation of the protrusion 145 within the mounting groove 144, the outer wall of the protrusion 145 has a cylindrical wall, and the inner wall of the mounting groove 144 has a corresponding cylindrical wall.

[0071] Please refer to the following: Figures 1 to 7When the supplementary lighting device 100 is actually used, the clamping part 21 clamps the mobile phone 57 to the placement part 212 through two pushing parts 2121, and the floodlight 2 and the first lamp holder 1 are connected by the connecting part 23 through the rotating part 22. The connecting part 23 is connected to the third fixed frame 55 at the first end of the first lamp holder 1 through the tilting structure. The handle 56 at the connecting part 23 has a prismatic structure, which makes it convenient for the user to fix or loosen the rotation of the connecting part 23 on the third fixed frame 55 by hand. The mounting part 14 is installed on the tabletop 58. The pressure end face 1421 of the pressure member 142 and the pressure bearing end face 1412 of the U-shaped bracket 141 abut against the two surfaces of the tabletop 58 and fix the first lamp holder 1 to the tabletop 58. The mounting part 14 is connected to the first fixing member 53, the first fixing member 53 is connected to the first frame 51, the first frame 51 is connected to the second fixing member 54, the second fixing member 54 is connected to both the first frame 51 and the second frame 52, and the straight line formed by connecting the two connecting shafts 122 corresponding to the first frame 51 on the second fixing member 54 is not parallel to the straight line formed by connecting the two connecting shafts 122 corresponding to the second frame 52 on the second fixing member 54. This makes the angle between the second frame 52 and the first frame 51 smaller, so that the second frame 52 is more lateral to the table surface 58, and the beam direction of the floodlight 2 is closer to the vertical direction penetrating the table surface 58; the prismatic handle 4 is set on a connecting shaft 122 of the second fixed member 54, which makes it convenient for the user to tighten / loosen the abutment between the arm strip 111 of the second frame 52 and the connecting plate 121 of the second fixed member 54; the second lamp holder 31 is fixed on the second frame 52 and the spotlight 3 is fixed on the first lamp holder 1, so that the user can use the spotlight 3 together with the floodlight 2 on the first lamp holder 1 and easily adjust the angle and position of the spotlight 3.

[0072] The second frame 52 is provided with a mounting post 132. A nut 123 on a connecting shaft 122 of the second fixed member 54 protrudes laterally from the second fixed member 54. A spring 13 is attached to the mounting post 132 on the second frame 52 and the nut 123 protruding laterally from the second fixed member 54. When the second frame 52 is connected to the second fixed member 54 and swings downward, the distance between the nut 123 protruding laterally from the second fixed member 54 near the outer side of the platform 58 and the mounting post 132 near the inner side of the platform 58 increases, thereby stretching the spring 13. At this time, the spring 13 relies on its restoring force to maintain the upward swinging tendency of the second frame 52 to which it is connected, increasing the stability of the first lamp holder 1.

[0073] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
