Description

Technical Field

[0001] This application relates to the field of fill lights, and more particularly to a fill light for mobile phones. Background Technology

[0002] Photographers typically use supplemental lighting to ensure sufficient illumination when taking photos. However, supplemental lighting is mainly geared towards the camcorder market. With the increasing prevalence of mobile phone photography, supplemental lighting for mobile phone photography currently relies on either the phone's built-in flash or an external independent supplemental light. The built-in flash of a mobile phone has relatively low brightness, resulting in poor photo quality, while external independent supplemental lights are less convenient to use. Therefore, supplemental lights installed on the phone are preferred. To keep the phone stable during shooting, supplemental lights are devices with a shutter button.

[0003] In related technologies, such as CN215526322U, there is a fill light that can be used to mount a mobile phone. The working principle is as follows: a fill light source is set on the front of the lamp body, a control panel is set on the surface of the lamp body, and a mounting bracket for mounting a mobile phone is set on the back of the lamp body. When in use, the fill light can be used alone, or the mobile phone can be mounted on the mounting bracket when the user takes a picture with the mobile phone, so that the lamp body is located on the back of the mobile phone, so that the user can use the fill light at the same time when holding the mobile phone, which is convenient for the user to take pictures.

[0004] The aforementioned technologies have the drawback that because the position of the supplementary light source is fixed, the shooting method of the mobile phone is also fixed, thus making it impossible to freely adapt to front-facing and rear-facing shooting. Summary of the Invention

[0005] In order to freely adapt to the needs of front-facing and rear-facing shooting, this application provides a fill light for mobile phones.

[0006] The technical solution for a mobile phone fill light provided in this application is as follows: A mobile phone fill light includes: The carrier plate has one large surface designated as a clamping surface. A handle, attached to one end of the carrier plate, is located on the short side of the clamping surface and is equipped with a quick-click button; A mounting bracket is provided on the clamping surface for securing the mobile phone; Two fill light plates are located on the two long sides of the clamping surface, respectively. The fill light plates are damped and folded to the end of the carrier plate away from the handle, so as to switch the fill light plates between the position adjacent to the long side of the clamping surface and the position on the side of the carrier plate away from the clamping surface. A dimming button is disposed on the surface of the carrier plate opposite to the clamping surface. The dimming button is located at one end of the carrier plate near the handle, and a plurality of dimming buttons are distributed along the length of the handle.

[0007] By adopting the above technical solution, firstly, by using the two fill light plates to fold, when taking photos with the front camera, the fill light plates can be flipped to a position adjacent to the long side of the clamping surface. When taking photos with the rear camera, the fill light plates can be folded to a position where the carrier plate is away from the clamping surface. This allows the fill light plates to provide fill light forward or backward, thus freely adapting to both front and rear camera shooting. At the same time, the fill light plates are damped when folded, meaning the light emission angle of the fill light plates can be freely set. In addition, minimizing storage is also achieved when the fill light plates are folded to a position where the carrier plate is away from the clamping surface. Secondly, the position of the handle and the dimming button makes it easier for the hand holding the handle to touch the dimming button, thus making it more convenient for people to use with one hand for shooting.

[0008] Preferably, the handle extends away from the clamping surface, and the clamping surface and the direction of the handle extension are set at an acute angle.

[0009] By adopting the above technical solution, the fill light can be placed on a horizontal table or desktop by holding the handle, thereby expanding the application scenarios of the fill light.

[0010] Preferably, the mounting bracket includes two variable-width sliders, two clamping blocks, and a clamping spring. The variable-width sliders are located on the end of the carrier plate away from the handle, and the two variable-width sliders are respectively located on the two long sides of the clamping surface. The variable-width sliders are slidably connected to the carrier plate, and the two variable-width sliders move closer to or further away from each other. The two clamping blocks are respectively connected to the two variable-width sliders, and the clamping blocks are rotatably connected to the variable-width sliders to switch the clamping blocks between an attitude perpendicular to the clamping surface and an attitude parallel to the clamping surface. The clamping spring is connected to the variable-width sliders to apply a force that brings the two variable-width sliders closer together. The fill light plate is damped and folded connected to the variable-width sliders.

[0011] By adopting the above technical solution, while clamping mobile phones of different sizes and specifications through the widening slider, clamping block and clamping spring, the fill light plate can move with the widening slider. Therefore, after the mobile phone is installed on the carrier plate, the position of the fill light plate will be on the outside of the mobile phone, so that the fill light plate can also adapt to the size and specifications of the mobile phone.

[0012] Preferably, the carrier plate has two splicing notches at the end away from the handle, and the two splicing notches are respectively located on the two long sides of the clamping surface; the widening slider is divided into an inner connecting part and an outer connecting part. The inner connecting part is slidably disposed inside the carrier plate and is connected to the clamping spring disposed inside the carrier plate. The outer connecting part is located in the splicing notches. The end of the outer connecting part near the inner connecting part is provided with a connecting groove. The connecting groove is used for the clamping block to be pivotally embedded and connected. The clamping surface is provided with a retractable groove. The retractable groove accommodates the part of the clamping block located outside the connecting groove. The end of the outer connecting part away from the inner connecting part is provided with a folding inner groove. The end of the fill light plate near the outer connecting part is provided with a folding outer groove. The folding inner groove and the folding outer groove are connected and connected. A chain link is accommodated between the folding inner groove and the folding outer groove. The two ends of the chain link are respectively damped pivotally embedded and connected in the folding inner groove and the folding outer groove.

[0013] By adopting the above technical solutions, firstly, the inner connecting part with the carrier plate, the clamping spring inside the carrier plate, and the fit between the outer connecting part and the splicing notch, the connection structure between the widening slider and the carrier plate can be made more compact; secondly, the fit between the clamping block, the connecting groove, and the retracting groove can make the fit structure between the mounting frame and the carrier plate more compact; thirdly, the fit between the chain link block, the folding inner groove, and the folding outer groove can make the fit structure between the fill light plate and the widening slider more compact. In summary, the fill light can be more compact and thinner, thus making it easier to carry and store.

[0014] Preferably, the fill light plate is divided into a connecting part and a light-emitting part. The connecting part is connected to the chain link block. The light-emitting part is cuboid in shape, and the length direction of the light-emitting part is parallel to the long side of the clamping surface. A conductive slip ring is provided between the connecting part and the light-emitting part. The stator of the conductive slip ring is connected to the connecting part, and the rotor of the conductive slip ring is connected to the corner of the light-emitting part near the connecting part and away from the handle. The stator and rotor of the conductive slip ring rotate with damping.

[0015] By adopting the above technical solution, the light-emitting part can be rotated by the conductive slip ring to change the distance of the end of the light-emitting part away from the clamping surface, so as to adapt to different sizes of supplementary lighting range. At the same time, the light-emitting part can be extended at an angle in the direction away from the clamping surface, so that the light-emitting part can also take into account the lighting along the long side of the clamping surface, thereby adapting to richer and more diverse supplementary lighting needs.

[0016] Preferably, the stator of the conductive slip ring is connected to a conductive slider, the conductive slider is slidably connected to the connecting part, the conductive slider slides with damping of the connecting part, and the conductive slider slides along the long side of the clamping surface.

[0017] By adopting the above technical solution, since the light-emitting part will gradually move away from the handle during the rotation of the light-emitting part via the conductive slip ring, a conductive slider is provided in order to keep the light-emitting part centered for supplementary lighting, so that the light-emitting part can move along the long side of the clamping surface. At the same time, the conductive slip ring and the conductive slider can cooperate to expand the position range of the light-emitting part, thereby adapting to more diverse supplementary lighting needs.

[0018] Preferably, one of the chain links is divided into two single chain blocks. One single chain block is connected to the connecting part, and the other single chain block is connected to the external connecting part. The two single chain blocks are connected by a damped sliding connection and are interlocked sliding connections, which are used to change the distance between the connecting part and the external connecting part.

[0019] By adopting the above technical solution, when the length direction of the light-emitting part is perpendicular to the long side direction of the clamping surface, the end of the light-emitting part that is furthest from the clamping surface is the furthest from the clamping surface. At this time, combined with the distance between the two single chain blocks, the distance between the light-emitting part and the clamping surface can be further expanded, so the supplementary light range can also be expanded, thereby enriching more supplementary light application scenarios.

[0020] Preferably, the connecting part and the light-emitting part are provided with a splicing plug and a splicing socket between the conductive slip ring and the conductive slider. The splicing plug is connected to the conductive slider and is inserted into the connecting part. The splicing socket is connected to the rotor of the conductive slip ring and is used for the light-emitting part to be inserted into the splicing socket.

[0021] By adopting the above technical solution, in scenarios where diverse changes in supplementary lighting requirements are not required, such as using conductive sliders and conductive slip rings, the splicing plug can be removed from the connecting part, the splicing socket can be removed from the light-emitting part, and the light-emitting part can be directly connected to the connecting part. Thus, users can customize the supplementary lighting according to their own needs.

[0022] Preferably, the inner folding groove and the outer folding groove are configured as through grooves connecting the clamping surface and the two sides away from the clamping surface.

[0023] By adopting the above technical solution, compared with the method of connecting the inner and outer folding grooves only to the side of the carrier plate away from the clamping surface, this design allows the fill light plate to fold forward. This can not only adapt to different fill light needs, but also allow the two fill light plates to converge towards the user's location when the fill light plate is far away from the mobile phone, thereby improving the practicality of the fill light.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Firstly, by using two folding fill lights, when taking photos with the front camera, the fill lights can be flipped to a position adjacent to the long side of the clamping surface. When taking photos with the rear camera, the fill lights can be folded to a position where the carrier plate is away from the clamping surface. This allows the fill lights to illuminate forward or backward, thus freely adapting to both front and rear camera shooting. Furthermore, the fill lights are damped during folding, meaning the beam angle can be freely adjusted. Additionally, folding the fill lights to the position where the carrier plate is away from the clamping surface also minimizes storage space. Secondly, the position of the handle and the dimming button allows for easy access to the dimming button while holding the handle, making it more convenient for one-handed use. 2. Firstly, the inner connecting part with the carrier plate, the clamping spring embedded in the carrier plate, and the fit between the outer connecting part and the splicing notch make the connection structure between the widening slider and the carrier plate more compact. Secondly, the fit between the clamping block, the connecting groove, and the retracting groove makes the fit structure between the mounting frame and the carrier plate more compact. Thirdly, the fit between the chain link block, the folding inner groove, and the folding outer groove makes the fit structure between the fill light plate and the widening slider more compact. In summary, the fill light can be more compact and thinner, making it easier to carry and store. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses a fill light for mobile phones.

[0035] Example 1.

[0036] Reference Figure 1 and Figure 2 The mobile phone fill light includes a carrier plate 1, a grip 2, a mounting bracket 3, and a fill light plate 4. The carrier plate 1 is roughly a thin rectangular parallelepiped. One large side of the carrier plate 1 will contact the mobile phone; for ease of description, this large side is designated as the clamping surface 11. The grip 2 is a long cylindrical shape and is connected to one end of the carrier plate 1 along its length. Specifically, the grip 2 is located on the short side of the clamping surface 11, and the generatrix of the grip 2 is parallel to the short side of the clamping surface 11. A quick-capture button 21 is provided on one end of the grip 2 along its length. The mounting bracket 3 is mounted on the clamping surface 11. Used to fix the mobile phone; the fill light plate 4 is a plate with an integrated LED light source. The fill light plate 4 is a thin cuboid shape. One side of the fill light plate 4 emits light. There are two fill light plates 4. The two fill light plates 4 are located on the two long sides of the clamping surface 11 respectively. The fill light plate 4 is connected to the end of the carrier plate 1 away from the handle 2 by damping and flipping. By flipping, the fill light plate 4 can be positioned on the long side of the clamping surface 11, so that the fill light plate 4 and the clamping surface 11 are on the same plane and are attached to the side surface of the carrier plate 1 that is opposite to the clamping surface 11. The position can be switched between these two positions.

[0037] Reference Figure 1 and Figure 2When the fill light is in use, the back of the phone will be attached to the clamping surface 11. The back is only a non-touchscreen surface, and the phone camera is not in the area where the clamping surface 11 is located. If the front camera is used for shooting, the fill light plate 4 can be flipped to a position adjacent to the long side of the clamping surface 11. If the rear camera is used for shooting, the fill light plate 4 can be folded to a position on the carrier plate 1 away from the clamping surface 11. This allows the fill light plate 4 to provide fill light forward or backward, thus freely adapting to both front and rear camera shooting. At the same time, since the fill light plate 4 has a damped folding setting, it can be fixed in different positions during the folding process, so the light emission angle of the fill light plate 4 can be freely changed. In addition, when not in use, the fill light plate 4 can be folded to the side of the carrier plate 1 away from the clamping surface 11 to achieve minimal storage.

[0038] Reference Figure 1 and Figure 2 From the perspective of improving the user experience, the handle 2 is preferably connected to the carrier plate 1 as a whole. The advantage of this is that when holding the handle 2, the fill light can be controlled more stably as a whole, so that shooting can be carried out stably. Of course, if this is not considered, the handle 2 and the carrier plate 1 can be detached. The reason for this setting is that the outer circumference of the handle 2 is usually curved, and the thickness of the handle 2 is significantly greater than that of the carrier plate 1. When the handle 2 is removed, the carrier plate 1 and the handle 2 can be placed separately, so the fill light can be stored more compactly, and thus it is easier to carry the fill light.

[0039] Reference Figure 1 and Figure 2 Since there is a need to change the brightness and color of the fill light plate 4 during use, the carrier plate 1 is equipped with a dimming button 12. The dimming button 12 is located on the surface of the carrier plate 1 away from the clamping surface 11. The dimming button 12 is located at one end of the carrier plate 1 near the handle 2. At the same time, multiple dimming buttons 12 are distributed along the length of the handle 2. In this way, when holding the handle 2, the fingers can easily touch the dimming buttons 12 in different positions, which makes it easier for the user to operate the fill light.

[0040] Reference Figure 1 and Figure 2In daily use, there is also a need to place it on a table or desktop, such as when using a mobile phone for live streaming. To accommodate this scenario, the handle 2 extends to the side opposite to the clamping surface 11, so that the long end face of the handle 2 (i.e. the end face perpendicular to the generatrix of the cylinder) is close to an oval shape. At the same time, the clamping surface 11 and the extension direction of the handle 2 form an acute angle, so that the mobile phone can be placed on the table or desktop in an upturned position. In addition, the thickness of the side of the handle 2 away from the clamping surface 11 is greater than the thickness of the side closer to the clamping surface 11. This allows the center of gravity of the fill light and the mobile phone as a whole to be slightly rearward, that is, to make the center of gravity further away from the side where the clamping surface 11 is located, thereby improving the placement stability of the fill light.

[0041] Reference Figure 1 and Figure 3 Because mobile phones come in different sizes, the mounting bracket 3 needs to be adapted to fit the size of the mobile phone. Specifically, the mounting bracket 3 includes two widening sliders 31, two clamping blocks 32, and clamping springs 33. The widening sliders 31 are located on the end of the carrier plate 1 away from the handle 2. The two widening sliders 31 are located on the two long sides of the clamping surface 11, respectively. The widening sliders 31 are slidably connected to the carrier plate 1, and the two widening sliders 31 can move closer or further apart. The two clamping blocks 32 are respectively connected to the two widening sliders 31, and the clamping blocks 32 are connected to the widening sliders. On the side of clamping surface 11, clamping block 32 is rotatably connected to widening slider 31, with the axis of rotation parallel to the long side of clamping surface 11. This allows clamping block 32 to switch between two postures: perpendicular to clamping surface 11 and parallel to clamping surface 11. In other words, clamping block 32 can be opened to clamp the phone and closed to store it. Clamping spring 33 is connected to widening slider 31. The elastic force of clamping spring 33 is converted into a force that brings the two widening sliders 31 closer together, so that the two clamping blocks 32 can firmly clamp the phone.

[0042] In this embodiment, considering that the fill light plate 4 also needs to be arranged according to the size of the mobile phone, that is, the mobile phone should not block the fill light plate 4. At the same time, in order to take into account the convenience of use, that is, it is not necessary to adjust the fill light plate 4 after the mobile phone is installed on the fill light. Specifically, the fill light plate 4 is damped and flipped to the side of the widening slider 31 away from the carrier plate 1. In this way, the fill light plate 4 can move with the widening slider 31. After the mobile phone is installed on the carrier plate 1, the position of the fill light plate 4 will be on the outside of the mobile phone, so that the fill light plate 4 can also adapt to the size of the mobile phone.

[0043] Reference Figure 1 and Figure 3To make the fill light structure more compact and thinner, with compactness manifested as a flatter surface—meaning the fill light's surface won't have excessively uneven areas in its unfolded or folded state for easier storage and portability—the following design is implemented: First, two splicing notches 13 are provided at the end of the carrier plate 1 away from the handle 2. These two notches 13 are located on the two long sides of the clamping surface 11. Simultaneously, the widening slider 31 is divided into an inner connecting part 311 and an outer connecting part 312. The inner connecting part 311 slides through the interior of the carrier plate 1 and is connected to a clamping spring 33 internally located on the carrier plate 1. Specifically, a spring-loaded cavity 15 is formed at the internal rib structure of the carrier plate 1, with one spring-loaded cavity 15 corresponding to one clamping spring 33. The inner connecting part 311 has a spring-loaded portion 31 passing through the spring-loaded cavity 15. 11. The spring mounting part 3111 is in the shape of a stepped shaft. The area of ​​the spring mounting part 3111 near the light-filling plate 4 has a smaller diameter, and the area away from the light-filling plate 4 has a larger diameter. The clamping spring 33 is located in the spring mounting cavity 15. The clamping spring 33 is sleeved on the end of the spring mounting part 3111 with a smaller diameter. One end of the clamping spring 33 abuts against the inner wall of the spring mounting cavity 15, and the other end abuts against the end face of the larger diameter part of the spring mounting part 3111. In this way, the clamping spring 33 is built in, and the clamping spring 33 can also apply a mutual force to the widening slider 31. The outer connecting part 312 is located in the splicing notch 13. The outer connecting part 312 just fills the area where the splicing notch 13 is located, so that it can be seen from the clamping surface 11 as a complete rectangle. In summary, the fit structure between the widening slider 31 and the carrier plate 1 can be more compact and thinner.

[0044] Reference Figure 1 and Figure 3 Secondly, the outer connecting part 312 has a connecting groove 5 at one end near the inner connecting part 311. The opening of the connecting groove 5 faces the side where the clamping surface 11 is located. The connecting groove 5 is used for the clamping block 32 to be rotatably embedded and connected. That is, a rotating shaft is installed at the connecting groove 5, and the clamping block 32 is then sleeved on this rotating shaft to realize the rotatable connection between the clamping block 32 and the outer connecting part 312. At the same time, a receiving groove 14 is provided at the clamping surface 11. The receiving groove 14 is connected to the connecting groove 5. The receiving groove 14 accommodates the part of the clamping block 32 located outside the connecting groove 5. In summary, when storing, the clamping block 32 can be rotated into the receiving groove 14 and the connecting groove 5 so that the clamping block 32 will not protrude outside the clamping surface 11. Therefore, the fit structure between the clamping block 32 and the carrier plate 1 can be made more compact and thinner.

[0045] Reference Figure 1 and Figure 4Thirdly, the outer connecting part 312 has a folded inner groove 51 at the end away from the inner connecting part 311, and the supplementary light plate 4 has a folded outer groove 52 at the end near the outer connecting part 312. The openings of the folded inner groove 51 and the folded outer groove 52 are both away from the side where the clamping surface 11 is located. The side wall of the folded inner groove 51 is open, and the side wall of the folded outer groove 52 is open. The openings of the folded inner groove 51 and the folded outer groove 52 are opposite to each other. A chain link block 6 is accommodated between the folded inner groove 51 and the folded outer groove 52. The two ends of the chain link block 6 are respectively damped pivots embedded in the folded inner groove 51 and the folded outer groove 52. Specifically, the folded inner groove 51 and the folded outer groove 52 are... Each outer groove is equipped with a damping shaft, and the chain link 6 is then fixedly sleeved on this damping shaft. The damping rotation allows the chain link 6 to stop at any position with different angles relative to the lighting plate 4 or the outer connecting part 312. In summary, when the lighting plate 4 is flipped to a position adjacent to the clamping surface 11, the outer surfaces of the chain link 6, the lighting plate 4, and the widening slider 31 can be flat without any uneven areas. When the lighting plate 4 is flipped to the side facing away from the clamping surface 11, the chain link 6 is just wrapped by the widening slider 31 and the lighting plate 4, so the fit between the widening slider 31 and the lighting plate 4 can be more compact and thinner.

[0046] In addition, in this embodiment, in order to maintain the normal use of the fill light plate 4, the chain link block 6 will have a wire passage 64 to connect the circuit structure between the carrier board 1 and the fill light plate 4.

[0047] The implementation principle of a mobile phone fill light in Embodiment 1 of this application is as follows: First, by using the folding method of the two fill light plates 4, when taking a front-facing photo, the fill light plate 4 can be flipped to a position adjacent to the long side of the clamping surface 11. When taking a rear-facing photo, the fill light plate 4 can be folded to a position on the side of the carrier plate 1 away from the clamping surface 11. In this way, the fill light plate 4 can provide fill light forward or backward, so it can be freely adapted to front-facing and rear-facing photos. At the same time, the fill light plate 4 is damped and folded, that is, the light emission angle of the fill light plate 4 can be freely set. In addition, when the fill light plate 4 is folded to a position on the side of the carrier plate 1 away from the clamping surface 11, the need for minimizing storage can also be achieved. Second, the position of the handle 2 and the dimming button 12 makes it easier for the hand holding the handle 2 to touch the dimming button 12, so it is more convenient for people to use it with one hand for shooting.

[0048] Example 2.

[0049] Reference Figure 1 and Figure 5The difference from Embodiment 1 is that since the fill light plate 4 is folded to the side facing away from the clamping surface 11, the width of the fill light plate 4 is half the width of the clamping surface 11. Thus, when the fill light plate 4 is folded to a position adjacent to the clamping surface 11, the fill light plate 4 will not be far enough from the farthest position of the mobile phone, so it will not be able to adapt to a wider fill light range. Therefore, the difference in Embodiment 2 will solve the aforementioned problems.

[0050] Reference Figure 5 and Figure 6 Specifically, the fill light plate 4 is divided into a connecting part 41 and a light-emitting part 42. The connecting part 41 is connected to the chain link block 6. The light-emitting part 42 is rectangular and its length is parallel to the long side of the clamping surface 11. A conductive slip ring 7 is provided between the connecting part 41 and the light-emitting part 42. The stator of the conductive slip ring 7 is connected to the connecting part 41, and the rotor of the conductive slip ring 7 is connected to the corner of the light-emitting part 42 near the connecting part 41 and away from the handle 2. The stator and rotor of the conductive slip ring 7 rotate with damping. Damped rotation means that the rotor of the conductive slip ring 7 can stop arbitrarily on the stator. Under the action of the conductive slip ring 7, the light-emitting part 42 can be rotated, so that the light-emitting part 42 rotates around the stator of the conductive slip ring 7 in the plane of the carrier plate 1, thereby changing the angle between the light-emitting part 42 and the connecting part 41, and thus further changing the position of the fill light plate 4 furthest from the mobile phone. Therefore, it can be adapted to different sizes of fill light illumination range.

[0051] Furthermore, rotating the light-emitting part 42 can also cause the light-emitting part 42 to extend at different angles with the connecting part 41. In this way, the light-emitting part 42 can also provide illumination to both sides of the long side of the clamping surface 11, thus adapting to more diverse lighting needs.

[0052] Reference Figure 5 and Figure 6 As the light-emitting part 42 gradually moves away from the handle 2 during the rotation of the conductive slip ring 7, the following configuration is provided to ensure that the light-emitting part 42 can be centered for supplementary lighting: the stator of the conductive slip ring 7 is connected to a conductive slider 71, which is slidably connected to the connecting part 41. That is, the conductive slider 71 and the connecting part 41 achieve motion transmission through the contact point. At the same time, the conductive slider 71 and the connecting part 41 slide with damping. Specifically, the conductive slider 71 and the connecting part 41 are connected by a T-shaped slider groove. The T-shaped groove is provided with an elastic pad, and the elastic pad and the T-shaped slider form a structure similar to an interference fit. The friction of the elastic pad is used as a damping force to allow the conductive slider 71 to stop at different positions. In this way, the light-emitting part 42 can be gradually moved closer to or away from the handle 2 and stopped at different distances from the handle 2 by the conductive slider 71, so that the light-emitting part 42 can be centered for supplementary lighting.

[0053] Furthermore, with the synergistic effect of the conductive slip ring 7 and the conductive slider 71, the light-emitting part 42 can be rotated by the conductive slip ring 7 so that the length direction of the light-emitting part 42 is perpendicular to the long side of the clamping surface 11. Then, one of the light-emitting parts 42 can be slid to be located on the side of the connecting part 41 away from the handle 2, and the other light-emitting part 42 can be slid to be located on the end of the connecting part 41 close to the handle 2, thereby adapting to a wider range of supplementary lighting needs.

[0054] Reference Figure 5 and Figure 6 Since reversing the length and width directions of the light-emitting part 42 has limited effect on increasing the supplementary lighting range, the following arrangement is made to appropriately extend the distance between the light-emitting part 42 and the clamping surface 11: one link block 6 is divided into two single chain blocks 61. One single chain block 61 is connected to the connecting part 41, and the other single chain block 61 is connected to the external connecting part 312. At the same time, the two single chain blocks 61 are connected by a damped sliding connection and an interlocking sliding connection. Specifically, one single chain block 61 is provided with a guide block 62 and a guide groove 63. The guide block 62 slides through the guide groove 63 of the other single chain block 61. An elastic pad is provided in the guide groove 63. The elastic pad is interference-fitted with the guide block 62 to apply a damping force to stop the guide block 62. In this way, the two single chain blocks 61 can stop at different intervals, so the distance between the light-emitting part 42 and the clamping surface 11 can be further expanded, thereby expanding the supplementary lighting range.

[0055] Reference Figure 5 and Figure 6 As the light-emitting part 42 moves further away from the clamping surface 11, the light-gathering ability of the two light-emitting parts 42 will weaken if they are adjacent to the clamping surface 11. Therefore, in order to still be able to focus light when the light-emitting part 42 is further away from the clamping surface 11, the inner folding groove 51 and the outer folding groove 52 are connected to the clamping surface 11 and the two sides opposite to the clamping surface 11. That is, the inner folding groove 51 and the outer folding groove 52 are connected to both the plane where the clamping surface 11 is located and the surface of the carrier plate 1 opposite to the clamping surface 11. In this way, the fill light plate 4 can be folded forward, that is, folded towards the user. At this time, the effect of focused fill light can be enhanced, and the defects caused by the light-emitting part 42 being far away from the clamping surface 11 can also be compensated for. This can improve the practicality of the fill light. The practicality here can be understood as the user being able to easily adjust the working parameters of the fill light to adapt to different photography needs.

[0056] Reference Figure 5 and Figure 7Considering that users have different photography needs in different scenarios—that is, the photography needs may be slightly weaker in some scenarios, or the photography standards that can be achieved may vary due to differences in users' photography skills (lower photography standards require lower photography needs)—the following configuration is made to accommodate this situation: a splicing plug 72 and a splicing socket 73 are provided between the conductive slip ring 7 and the conductive slider 71 in the connecting part 41 and the light-emitting part 42. The splicing plug 72 is connected to the conductive slider 71, that is, the conductive slider 71 slides and connects to the splicing plug 72. The connector 72 is located on the connecting section 41, providing both structural and electrical connections. The connecting socket 73 connects to the rotor of the conductive slip ring 7, allowing the light-emitting unit 42 to be plugged in. This allows the connector 72 to be removed from the connecting section 41 and the connecting socket 73 to be removed from the light-emitting unit 42, enabling direct connection between the light-emitting unit 42 and the connecting section 41. This creates a basic fill light suitable for low-demand photography. For higher-demand photography, the light-emitting unit 42 can be indirectly connected to the connecting section 41 via the connector 72 and connecting socket 73, allowing for various precise and detailed fill light adjustments. This allows users to customize the fill light to their specific needs.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
