Description

Technical Field

[0001] The present application relates to the technical field of photographic lighting, and in particular to a leveling assembly and a photographic lighting device using the leveling assembly. Background Art

[0002] A video light is a device that provides illumination for a shooting scene. Depending on your shooting needs, you can pair it with different optical accessories to create different lighting effects. Different optical accessories have varying weights, so when you replace a video light with a different optical accessory, the center of gravity of the light and the accessories will change accordingly.

[0003] In the related art, the connection position between the connecting frame and the video light is relatively fixed. Therefore, when the video light is replaced with different optical accessories, the center of gravity of the whole will also change accordingly. For example, after the center of gravity of the whole formed by the video light and the optical accessories moves forward, when the video light can rotate freely, the whole will rotate significantly under the influence of its own gravity, causing the staff to be more laborious when controlling the video light to rotate in the opposite direction, increasing the difficulty of the staff's operation. Utility Model Content

[0004] The embodiments of the present application provide a leveling assembly and a photographic light device, which can reduce the difficulty of operation for workers when performing leveling operations.

[0005] In a first aspect, an embodiment of the present application provides a leveling assembly for adjusting the relative position between a video light and a connecting frame, the leveling assembly comprising a guide rail assembly, a first limiting member, and a second limiting member;

[0006] The guide rail assembly includes a guide block and a guide rail. The guide block is used to connect to the connecting frame and slide with the guide rail. The guide rail is used to connect to the video light and has a slideway and a limiting groove. The end of the slideway along the extension direction has a stop wall. The limiting groove is connected to the slideway and includes a middle groove and two end grooves. The middle groove is located between the two end grooves along the extension direction.

[0007] The first limiting member is slidably disposed in the slideway and is provided with an abutting portion. The second limiting member is connected to the guide block and slidably cooperates with the first limiting member. The second limiting member can selectively cooperate with the middle groove and one of the two end grooves.

[0008] When the second limiting member is engaged with the abutting portion, the second limiting member can drive the first limiting member to move relative to the guide rail along the extension direction until the first limiting member is blocked by the stop wall, and then the second limiting member can extend into the middle groove and engage with the middle groove.

[0009] In some embodiments, the stop wall includes two stop walls, which are respectively provided at two ends of the slideway along its extension direction;

[0010] The abutting portion includes a first abutting portion and a second abutting portion, and the first abutting portion and the second abutting portion are arranged at intervals along the extending direction;

[0011] In which, when the second limiting member cooperates and abuts against the first abutting portion, the second limiting member can drive the first limiting member to move relative to the guide rail along the direction from one end groove to the middle groove; when the second limiting member abuts against the second abutting portion, the second limiting member can drive the first limiting member to move relative to the guide rail along the direction from the other end groove to the middle groove.

[0012] In some embodiments, the second limiting member is rotatable relative to the first limiting member to have a first state, a second state, and a third state;

[0013] In which, in the first state, the second limiting member can cooperate and abut with the abutment portion; in the second state, the second limiting member can abut with the side wall of the limiting groove; in the third state, there is a gap between the second limiting member and the side wall of the limiting groove and the abutment portion.

[0014] In some embodiments, the first limiting member has a sliding groove and an abutting groove, the sliding groove extends along the extending direction and is used for sliding of the second limiting member, the abutting groove is connected to the sliding groove, and a portion of its groove sidewall forms the abutting portion;

[0015] Wherein, in the first state, the second limiting member is located in the abutting groove to cooperate with and abut against the abutting portion.

[0016] In some embodiments, the second limiting member is provided through the guide block; and the leveling assembly further comprises:

[0017] a handle, disposed on a side of the guide block facing away from the guide rail and fixedly connected to a side of the second limiting member facing away from the guide rail, wherein the handle is rotatable relative to the guide block to drive the second limiting member to rotate relative to the first limiting member;

[0018] Wherein, a limiting structure is provided on a side of the guide block close to the handle, and the limiting structure is used to keep the second limiting member in the first state.

[0019] In some embodiments, a receiving groove is formed on a side of the handle facing the guide block;

[0020] The limiting structure is a limiting ball. When the second limiting member switches to the first state, the limiting ball is used to be embedded in the accommodating groove so that the second limiting member can remain in the first state.

[0021] In some embodiments, the leveling assembly further includes a slider, which is mounted on a side of the guide block facing the guide rail and is slidably connected to the guide rail.

[0022] In some embodiments, the slider includes a block body and a plurality of needle rollers;

[0023] The block body is mounted on a side of the guide block facing the guide rail, and a plurality of rolling grooves are formed on the side facing the guide rail, and the plurality of roller needles are arranged in the plurality of rolling grooves in a one-to-one correspondence;

[0024] Part of each of the rolling needles protrudes out of the notch of the rolling groove so as to be in rolling contact with the guide rail.

[0025] In some embodiments, there are two limiting grooves, and the two limiting grooves are located on opposite sides of the slideway along a direction perpendicular to the extending direction.

[0026] In a second aspect, an embodiment of the present application provides a photographic light device, comprising a photographic light, a connecting frame, and the leveling assembly described above, wherein the guide block is connected to the connecting frame, and the guide rail is connected to the photographic light;

[0027] The leveling component is used to adjust the relative position between the photographic light and the connecting frame.

[0028] Based on the leveling assembly and photographic light device of the embodiment of the present application, the relative position between the photographic light and the connecting frame can be adjusted by the leveling assembly, so that the connection position between the connecting frame and the photographic light can be as close as possible to the center of gravity of the photographic light device and the optical accessory as a whole, so that the gravitational torque of the photographic light device and the optical accessory as a whole is smaller. When the photographic light is rotated, the rotation amplitude of the whole formed by the photographic light device and the optical accessory is smaller. Therefore, when the staff operates the photographic light to rotate relative to the connecting frame, the torque of the power applied to the photographic light is smaller, which makes the staff more labor-saving during operation, thereby reducing the difficulty of operation for the staff.

[0029] Moreover, when the staff needs to limit the second limit piece with the middle groove, the stop wall can resist the first limit piece, so that the second limit piece can stay in the correct position, and then the second limit piece can be accurately extended into the middle groove, so that the staff can ensure that the second limit piece can stay in the correct position without repeatedly adjusting the relative position of the photographic light and the connecting frame. This makes it easier for the staff to extend the second limit piece into the middle groove, effectively reducing the difficulty of operation for the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0045] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0048] Please refer to Figures 1-6 The present application proposes a photographic light device 300. In an embodiment of the present application, the photographic light device 300 includes a photographic light 310, a connecting frame 320, and a leveling assembly 100. The leveling assembly 100 is arranged between the photographic light 310 and the connecting frame 320, and is used to adjust the relative position between the photographic light 310 and the connecting frame 320.

[0049] The video light 310 is used to emit light required for capturing a scene. The video light 310 can selectively connect to one of multiple optical accessories. The light emitted by the video light 310 is directed toward the optical accessory, which then modifies the light and transmits it to the outside world, creating various lighting effects. The video light 310 can be provided with a bayonet mount, and each optical accessory can be provided with an interface. The bayonet mount and the interface interface can be connected to achieve detachable connection between the video light 310 and each optical accessory. It is understood that the bayonet mount referred to herein can be the commonly used Bowens bayonet mount in the art, or can be a bayonet mount of varying specifications developed by various manufacturers, and this embodiment is not limiting in this regard.

[0050] Exemplarily, the photography light 310 may include a lamp housing and a light source. The light source may be an LED light source and is disposed in the lamp housing for emitting light to the outside. The bayonet is disposed on the lamp housing.

[0051] The connecting frame 320 connects the video light 310 to an external light stand. Specifically, the connecting frame 320 can be U-shaped or L-shaped, making the shape of the connecting frame 320 more regular and easier to process and manufacture. The connecting frame 320 can be made of a metal material such as aluminum alloy to provide excellent structural strength while enhancing the industrial aesthetics and quality of the connecting frame 320. This embodiment does not impose any specific restrictions on the shape and material of the connecting frame 320.

[0052] The leveling assembly 100 includes a guide rail assembly 10, a first stopper 20, and a second stopper 30. The guide rail assembly 10 includes a guide block 11 and a guide rail 12. Both the guide block 11 and the guide rail 12 can be made of metal to provide superior structural strength. The guide block 11 is connected to the connecting frame 320 and slidably engages with the guide rail 12. The guide rail 12 is connected to the video light 310.

[0053] The guide rail 12 includes a slideway 121 and a limiting groove 122. The slideway 121 has a stop wall 1211 at each end along its extension direction. This means that the stop wall 1211 may be provided at one end or at both ends of the slideway 121. The limiting groove 122 communicates with the slideway 121 and includes a middle groove 1221 and two end grooves 1222. The middle groove 1221 is located between the two end grooves 1222 along its extension direction. It is understood that the middle groove 1221 and the two end grooves 1222 are independent of each other.

[0054] The first stopper 20 can be made of metal to provide improved structural strength. The first stopper 20 is slidably disposed within the slide groove 22, meaning that the first stopper 20 can slide along the extension direction. The first stopper 20 is provided with an abutment portion 21. For example, the abutment portion 21 can be an abutment surface, and the abutment surface can be a curved surface or a flat surface, which is not limited in this embodiment.

[0055] The second stopper 30 can be made of metal, which provides improved structural strength. The second stopper 30 is connected to the guide block 11 and slidably engages with the first stopper 20. It is understood that when the guide block 11 slides relative to the guide rail 12, the guide block 11 drives the second stopper 30 to move, thereby enabling the second stopper 30 to slide on the first stopper 20. Furthermore, while the second stopper 30 is capable of sliding, it can slide to different positions along the extension direction of the guide rail 12, thereby selectively engaging with the middle groove 1221 or one of the two end grooves 1222.

[0056] For ease of understanding, this embodiment defines one of the end grooves 1222 as a first end groove and the other as a second end groove. The first end groove, the middle groove 1221 and the second end groove are arranged at intervals along the front to back direction of the lamp housing. After the photography light device 300 and the optical accessory of relatively light weight are installed, the overall center of gravity position will be relatively backward. Based on this, the user can allow the second limiting member 30 to cooperate with the first end groove to limit the connection position of the photography light 310 and the connecting frame 320, so that the connection position of the photography light device 300 and the optical accessory is close to the overall center of gravity position of the photography light device 300 and the optical accessory; after the photography light device 300 and the optical accessory of relatively moderate weight are installed, the overall center of gravity position will be relatively centered. Based on this, the user can allow the second limiting member 30 to cooperate with the middle groove 1221 to limit the connection position of the photography light 310 and the connecting frame 320, so that the connection position of the photography light device 300 and the optical accessory is close to the overall center of gravity position of the photography light device 300 and the optical accessory; after the photography light device 300 and the optical accessory of relatively heavy weight are installed, the overall center of gravity position will be relatively forward. Based on this, the user can allow the second limiting member 30 to cooperate with the first end groove to limit the connection position of the photography light 310 and the connecting frame 320, so that the connection position of the photography light device 300 and the optical accessory is close to the overall center of gravity position of the photography light device 300 and the optical accessory.

[0057] In this way, this embodiment can adjust the relative position between the photographic light 310 and the connecting frame 320 through the leveling component 100, so that the connection position between the connecting frame 320 and the photographic light 310 can be as close as possible to the center of gravity of the photographic light device 300 and the optical accessories as a whole, so that the gravitational torque of the photographic light device 300 and the optical accessories as a whole is smaller. When the photographic light 310 is rotated, the rotation amplitude of the whole formed by the photographic light device 300 and the optical accessories is smaller. Therefore, when the staff operates the photographic light 310 to rotate relative to the connecting frame 320, the torque of the power applied to the photographic light 310 is smaller, which makes the staff more labor-saving during operation, thereby reducing the difficulty of operation for the staff.

[0058] In the related art, since the two end grooves 1222 are located at the opposite ends of the slide 121, the limiting member in the related art only needs to slide to the front end or the rear end to be stopped at the precise position of the corresponding end groove 1222, and the subsequent limiting member can be accurately moved into the end groove 1222 and cooperate with the end groove 1222; and the middle groove 1221 is in the middle of the slide 121, so the limiting member in the related art will not be stopped in the process of sliding to the precise position of the corresponding middle groove 1221 of the slide 121, leading to This requires the staff to repeatedly adjust the relative position between the video light 310 and the connecting frame 320 until the limiting member stops at the precise position of the slide 121 corresponding to the middle groove 1221 before the limiting member can be extended into the middle groove 1221. This operation is very inconvenient, especially for some video lights 310 with higher output power. Since the lamp body of the video light 310 is heavy, it is more laborious to move the video light 310. It may even require two staff members to move the video light 310, resulting in a poor operating experience.

[0059] Based on this, in this embodiment, Figure 6 As shown in (a), when the second limiting member 30 is in contact with the abutting portion 21, the second limiting member 30 can drive the first limiting member 20 to move relative to the guide rail 12 along the extension direction until the first limiting member 20 is stopped by the stop wall 1211. It can be understood that during this movement, there is a gap between the second limiting member 30 and the groove wall of the limiting groove 122, so the second limiting member 30 will not contact the guide rail 12. Figure 6 As shown in (b), the second limiting member 30 can extend into the middle groove 1221 and cooperate with the middle groove 1221 in a limiting manner; for example, along the extension direction, it starts to move from the position corresponding to the slide 121 and the end groove 1222, and when the first limiting member 20 is blocked by the stop wall 1211, the second limiting member 30 stays at the position corresponding to the slide 121 and the middle groove 1221, and at this time the second limiting member 30 can extend into the middle groove 1221 and cooperate with the middle groove 1221 in a limiting manner.

[0060] In some feasible embodiments, the second limit member 30 can move in a direction perpendicular to the extension direction and move to engage with the abutment portion 21, and then the second limit member 30 drives the first limit member 20 to move relative to the guide rail 12 until the first limit member 20 is stopped after being blocked by the stop wall 1211, and finally the second limit member 30 still moves in a direction perpendicular to the extension direction to engage with the middle groove 1221; in other feasible embodiments, the second limit member 30 is a rotating member and has a rotation axis, and the second limit member 30 can rotate to engage with the abutment portion 21, and then the second limit member 30 drives the first limit member 20 to move relative to the guide rail 12 until the first limit member 20 is stopped after being blocked by the stop wall 1211, and finally the second limit member 30 continues to rotate along the rotation axis to engage with the middle groove 1221.

[0061] Therefore, when the staff needs to limit the second limit member 30 with the middle groove 1221, the stop wall 1211 can resist the first limit member 20, so that the second limit member 30 can stay in the correct position, and then the second limit member 30 can be accurately extended into the middle groove 1221, so that the staff can ensure that the second limit member 30 can stay in the correct position without repeatedly adjusting the relative position of the photographic light 310 and the connecting frame 320. This can make it easier for the staff to extend the second limit member 30 into the middle groove 1221, effectively reducing the difficulty of operation for the staff.

[0062] Please refer to Figure 4-Figure 7 In some embodiments, the stop wall 1211 includes two stop walls 1211, and the two stop walls 1211 are respectively arranged at the two ends of the slide 121 along its extension direction. It can be understood that on the basis that the slide 121 is in a long strip shape, the two stop walls 1211 are arranged opposite to each other.

[0063] The abutting portion 21 includes a first abutting portion 211 and a second abutting portion 212 . The first abutting portion 211 and the second abutting portion 212 are spaced apart along the extending direction.

[0064] Among them, Figure 6 As shown in (a), when the second limiting member 30 cooperates and abuts against the first abutting portion 211, the second limiting member 30 can drive the first limiting member 20 to move relative to the guide rail 12 along the direction from one end groove 1222 to the middle groove 1221; for the sake of convenience, the end groove 1222 explained here can be understood as the first end groove described in the above content.

[0065] like Figure 7As shown in (a), when the second limiting member 30 abuts against the second abutting portion 212, the second limiting member 30 can drive the first limiting member 20 to move relative to the guide rail 12 along the direction from the other end groove 1222 to the middle groove 1221; also for the sake of ease of understanding, the end groove 1222 explained here can be understood as the second end groove described in the above content.

[0066] In this way, no matter whether the photographic light device 300 is replaced with a lighter optical accessory to a medium-weight optical accessory, or replaced with a heavier optical accessory to a medium-weight optical accessory, the first limiting member 20 can be stopped by the stop wall 1211, so that the second limiting member 30 can be accurately moved to the position corresponding to the middle groove 1221 to cooperate with the middle groove 1221 for limiting, further facilitating the operation of the staff.

[0067] Please refer to Figure 3-Figure 7 In some embodiments, the second limiting member 30 can rotate relative to the first limiting member 20 and have a first state, a second state and a third state.

[0068] In the first state, the second limit member 30 can cooperate with the abutment portion 21 to abut against it, so that the second limit member 30 can drive the abutment portion 21 to move relative to the guide rail 12, so as to move from the position of the corresponding end groove 1222 of the slide 121 to the position of the corresponding middle groove 1221 of the slide 121.

[0069] In the second state, the second stopper 30 can engage with the sidewalls of the stopper slot 122, preventing relative movement between the video light 310 and the connecting bracket 320 along the extension direction. Exemplarily, the second stopper 30 includes a main body and a protruding portion. The protruding portion protrudes from the outer wall of the main body and is configured to engage with the sidewalls of the stopper slot 122 in the second state.

[0070] In the third state, there is a gap between the second limiting member 30 and the side wall of the limiting groove 122, and there is a gap between the second limiting member 30 and the abutting portion 21, so that the second limiting member 30 can slide without contacting the limiting groove 122 and the abutting portion 21. For example, when it is necessary to move the connection position of the photographic light 310 and the connecting frame 320 to the frontmost position, the second limiting member 30 can be rotated to the third state, and then the second limiting member 30 can be controlled to move relative to the guide rail 12 and move to the position of the corresponding second end groove of the slide 121.

[0071] In some exemplary operations, such as Figure 6 (a)- Figure 6As shown in (e), when it is necessary to limit the second limit member 30 located in the slide 121 at a position corresponding to the first end groove and the middle groove 1221, the second limit member 30 can be rotated first so that the second limit member 30 is in the first state, and then the second limit member 30 and the guide rail 12 are allowed to slide relative to each other until the first limit member 20 is blocked by the stop wall 1211, and then the second limit member 30 is rotated again so that the second limit member 30 is in the third state. If it is necessary to continue to adjust the second limit member 30 so that the second limit member 30 can be limited and matched with the second end groove, the second limit member 30 can be rotated first so that the second limit member 30 is in the third state, and then the second limit member 30 can be controlled to slide relative to the first limit member 20 to move to the position corresponding to the second end groove of the slide 121, and then the second limit member 30 can be rotated again so that the second limit member 30 is in the second state, so that it can be limited and matched with the second end groove.

[0072] In other exemplary operation processes, such as Figure 7 (a)- Figure 7 As shown in (e), when it is necessary to limit the second limit member 30 located in the position corresponding to the second end groove of the slide 121 and the middle groove 1221, the second limit member 30 can be rotated first so that the second limit member 30 is in the first state, and then the second limit member 30 and the guide rail 12 are allowed to slide relative to each other until the first limit member 20 is blocked by the stop wall 1211, and then the second limit member 30 is rotated again so that the second limit member 30 is in the third state. If it is necessary to continue to adjust the second limit member 30 so that the second limit member 30 can be limited and matched with the first end groove, the second limit member 30 can be rotated first so that the second limit member 30 is in the third state, and then the second limit member 30 can be controlled to slide relative to the first limit member 20 to move to the position corresponding to the first end groove of the slide 121, and then the second limit member 30 can be rotated again so that the second limit member 30 is in the second state, so that it can be limited and matched with the first end groove.

[0073] In this embodiment, when the staff needs to control the second limit member 30 to be in different states, they only need to control the second limit member 30 to rotate, and they can switch arbitrarily between the first state, the second state and the third state. The operation is convenient and fast, which effectively improves the user experience.

[0074] Please refer to Figure 3-Figure 5Furthermore, the first limiting member 20 has a sliding groove 22 and an abutting groove 23. The sliding groove 22 extends along the extension direction and is used for the second limiting member 30 to slide. It can be understood that the end of the sliding groove 22 along the extension direction can serve as a stop for the second limiting member 30, so that when the second limiting member 30 is in the third state and moves from the position corresponding to the middle groove 1221 of the slideway 121 to the position corresponding to the end groove 1222 of the slideway 121, the end of the sliding groove 22 along the extension direction will stop the second limiting member 30, so that the second limiting member 30 can subsequently switch from the third state to the second state to engage with the end groove 1222 for limiting. In addition, the sliding groove 22 can also guide the movement of the second limiting member 30, thereby effectively improving the movement accuracy of the second limiting member 30.

[0075] The abutting groove 23 is connected to the sliding groove 22, and a portion of the groove sidewall of the abutting groove 23 forms the abutting portion 21. In the first state, the second limiting member 30 is located in the abutting groove 23 to cooperate with the abutting portion 21. It can be understood that a portion of the groove sidewall of the abutting groove 23 forms the abutting portion 21, and the remaining portion of the groove sidewall can cooperate with the groove sidewall of the limiting groove 122 to jointly form a limiting cooperation with the second limiting member 30. In this way, the stability of the second limiting member 30 in the second state can be improved.

[0076] Please refer to Figure 2 、 Figure 3 、 Figure 8 as well as Figure 9 In some embodiments, the second limiting member 30 is provided through the guide block 11. Specifically, the second limiting member 30 may include a limiting block and a penetrating portion. The limiting block slides with the first limiting member 20. One side of the penetrating portion is fixedly connected to the limiting block, and the other side is provided through the guide block 11.

[0077] The leveling assembly 100 also includes a handle 40. The handle 40 is located on the side of the guide block 11 facing away from the guide rail 12 and is fixedly connected to the side of the second stopper 30 facing away from the guide rail 12, that is, to the other side of the penetration portion. It will be understood that the handle 40 provides a force point for the operator. Therefore, when the operator rotates the handle 40, the handle 40 drives the second stopper 30 to rotate. Specifically, the handle 40 can rotate relative to the guide block 11, thereby driving the second stopper 30 to rotate relative to the first stopper 20. Thus, the provision of the handle 40 facilitates operator operation of the second stopper 30.

[0078] Among them, a limiting structure 111 is provided on the side of the guide block 11 close to the handle 40. The limiting structure 111 is used to keep the second limiting member 30 in the first state, thereby ensuring the stability of the subsequent second limiting member 30 in driving the first limiting member 20 to move relative to the guide rail 12 along the extension direction, and providing feedback to the staff when the handle 40 switches from the first state to the second state. For example, the limiting structure 111 can be a magnet, and accordingly, the handle 40 can be a metal structure or the handle 40 can be provided with a magnetic attraction member that cooperates with the magnet. When the handle 40 switches to the first state, the magnet can adsorb the handle 40 itself or the magnetic attraction member, so that the second limiting member 30 can remain in the first state, and the staff can also obtain feedback that the handle 40 has switched to the second state. This embodiment does not specifically limit the type of limiting structure 111.

[0079] Please refer to Figure 2 、 Figure 3 、 Figure 8 as well as Figure 9 Furthermore, a receiving groove 41 is formed on the side of the handle 40 facing the guide block 11. The limiting structure 111 is a limiting ball. When the second limiting member 30 switches to the first state, the limiting ball is used to be embedded in the receiving groove 41 to keep the second limiting member 30 in the first state.

[0080] In this embodiment, the second limiting member 30 can be maintained in the first state by cooperating with the limiting ball and the accommodating groove 41. The structure is simple and the retention effect is better. The spherical setting of the limiting ball is conducive to its guiding and cooperating with the groove wall of the accommodating groove 41, thereby improving the smoothness of the handle 40 during rotation and enhancing the user experience.

[0081] See also Figure 3 In some embodiments, the leveling assembly 100 further includes a slider 50, which is mounted on the side of the guide block 11 facing the guide rail 12. For example, a mounting groove may be provided on the side of the guide block 11 facing the guide rail 12, and the mounting groove is used for installing the slider 50. This ensures the stability of the slider 50 installed on the guide block 11 and prevents it from loosening from the guide block 11.

[0082] The slider 50 is slidably connected to the guide rail 12. The arrangement of the slider 50 in this embodiment helps to improve the smoothness of sliding between the guide block 11 and the guide rail 12, effectively improving the user experience of the staff.

[0083] See also Figure 3 Optionally, the slider 50 includes a first slider and a second slider, and the first slider and the second slider are arranged at intervals in a direction perpendicular to the sliding direction of the guide block 11. In this way, the smoothness of sliding between the guide block 11 and the guide rail 12 can be further improved.

[0084] Please refer to Figure 3 and Figure 10 In some embodiments, the slider 50 includes a block body 51 and a plurality of needle rollers 52. The block body 51 is mounted on the side of the guide block 11 facing the guide rail 12, and a plurality of rolling grooves are formed on the side of the block body 51 facing the guide rail 12. The plurality of needle rollers 52 are disposed in a one-to-one correspondence within the plurality of rolling grooves, wherein a portion of each needle roller 52 protrudes from the notch of the rolling groove to enable rolling contact with the guide rail 12.

[0085] With this arrangement, the rolling contact between the plurality of needle rollers 52 and the guide rail 12 further improves the smoothness of the sliding of the slider 50 and the guide rail 12 , effectively improving the user experience of the staff.

[0086] In some embodiments, there are two limiting grooves 122. Along a direction perpendicular to the extension direction, the two limiting grooves 122 are located on opposite sides of the slideway 121. It is understood that there are two intermediate grooves 1221, two first end grooves, and two second end grooves, and along a direction perpendicular to the extension direction, the two intermediate grooves 1221 are oppositely disposed, the two first end grooves are oppositely disposed, and the two second end grooves are oppositely disposed.

[0087] In this way, the contact area between the second limiting member 30 and the side wall of the limiting groove 122 can be increased, so as to effectively improve the limiting effect of the second limiting member 30 and the limiting groove 122, and avoid relative movement between the photographic light 310 and the connecting frame 320 based on the cooperation between the second limiting member 30 and the limiting groove 122, thereby ensuring the stability of the photographic light device 300 during shooting.
