Technical Field

[0001] This utility model relates to the technical field of photographic lighting equipment, and more specifically, to a photographic lighting bracket and photographic lighting equipment. Background Technology

[0002] In the fields of film, video, and advertising shooting technology, in order to ensure the lighting effects of the subjects being shot, it is usually necessary to rely on professional lighting equipment for targeted lighting to meet the requirements of image quality and visual presentation.

[0003] As the scale of shooting scenes expands, single-light illumination can no longer meet the lighting and shadow requirements of complex scenes. The use of multiple lights in combination is becoming increasingly common, and this places diverse demands on the performance of multi-light lighting systems: First, they need to have a larger light-emitting surface to achieve more uniform light coverage; second, they need to be movable to adapt to the lighting adjustment needs of different shooting positions; and third, they need to support flexible adjustment of the illumination angle to accurately match the lighting and shadow requirements of the subject being shot.

[0004] However, the limitations of existing photography light brackets result in insufficient flexibility when using multiple lights in combination, making it difficult to efficiently adapt to the lighting needs of expanded shooting scenarios, thereby affecting shooting efficiency and image quality.

[0025] To make the technical problems, technical solutions, and beneficial effects 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.

[0026] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be located directly on or indirectly on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component.

They are only for the convenience of describing this utility model and do not indicate that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or the number of technical features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this utility model is described in more detail below with reference to specific embodiments: like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a photographic light bracket, comprising: The main frame 1 includes a transverse member 11 and two longitudinal members 12 respectively connected to both ends of the transverse member 11; Two support rods 2 are arranged parallel to each other and spaced apart; The connecting mechanism 3 allows each support rod 2 to be rotatably connected to the free end of the longitudinal member 12 on the corresponding side. Multiple first quick-release structures 4 are arranged in pairs and correspondingly on two support rods 2, and each pair of first quick-release structures 4 is used to support a lamp 10.

[0029] Specifically, the structure of the photographic light bracket includes a main frame 1, two support rods 2, a connecting mechanism 3, and multiple first quick-release structures 4. The main frame 1 is composed of a transverse member 11 and two longitudinal members 12 respectively connected to both ends of the transverse member 11. The two support rods 2 are parallel to each other and spaced apart. Each support rod 2 is rotatably connected to the free end of the corresponding longitudinal member 12 through the connecting mechanism 3. Multiple first quick-release structures 4 are arranged in pairs and correspondingly on the two support rods 2. Each pair of first quick-release structures 4 is used to support one light fixture 10.

[0030] Its working principle is as follows: the main frame 1 forms a basic support structure through the combination of the transverse component 11 and two longitudinal components 12, which provides stable support for the entire bracket. The rotatable characteristic of the connecting mechanism 3 allows the support rod 2 to adjust its angle around the free end of the corresponding longitudinal component 12, thereby driving the first quick-release structure 4 and the lamp 10 it carries to adjust its position and angle. The pair of first quick-release structures 4 can quickly complete the installation and removal of the lamp 10, and multiple first quick-release structures 4 can meet the requirement of carrying multiple lamps 10 at the same time.

[0031] Its technical effect lies in the fact that the angle of the support rod 2 can be adjusted through the connecting mechanism 3, which can adapt to the angle requirements of the light fixture 10 in different shooting scenarios. This solves the problem of poor adaptability caused by the fixed angle of the existing bracket. The first quick-release structure 4 simplifies the disassembly and assembly process of the light fixture 10 and improves the ease of operation. Multiple sets of the first quick-release structure 4 support multiple light fixtures 10, expanding the application scenarios. Combined with the stable support of the main frame 1, the overall practicality of the photography light bracket is enhanced, effectively solving the technical problem of poor adaptability and practicality of the photography light bracket in the existing technology.

[0032] In one embodiment, the first quick-release structure 4 can be plugged into the first quick-release mating structure of the lamp 10.

[0033] Specifically, from a structural perspective, the solution involves two core adapting structures: the first quick-release structure 4 on the photography light bracket and the first quick-release mating structure of the light fixture 10 itself. Both need to have matching plug-in forms in terms of size and shape (such as protrusions and grooves, buckles and slots, etc.) to meet the basic conditions for plug-in mating. The first quick-release structure 4, as part of the bracket, has been previously identified as being installed in pairs on the support rod 2, while the first quick-release mating structure is a matching structure specially designed on the light fixture 10 to achieve quick connection with the bracket.

[0034] In terms of working principle, when the lamp 10 needs to be installed on the bracket, simply align the first quick-release engagement structure of the lamp 10 with the corresponding first quick-release structure 4 on the bracket, and complete the quick connection between the two by inserting them together (such as inserting the protrusion into the groove or snapping the buckle into the slot), thus positioning and fixing the lamp 10 on the bracket. When the lamp 10 needs to be removed, simply apply a reverse force to release the insertion engagement between the two (such as pulling out the protrusion or disengaging the buckle from the slot), and the lamp 10 can be quickly removed from the bracket without the need for additional tools.

[0035] By adopting the above technical solution, this plug-in quick-release design firstly greatly simplifies the assembly and disassembly process of the lamp 10. Compared with the traditional method of fixing with bolts, nuts and other fasteners, it eliminates the need for tool operation, shortens the assembly and disassembly time, and significantly improves the ease of operation, solving the problems of low efficiency and cumbersome operation in traditional assembly and disassembly. Secondly, the compatible plug-in structure can ensure the connection stability of the lamp 10 after assembly, avoiding displacement or falling of the lamp 10 due to loose connection, and ensuring the reliability of the lamp 10's position during photography. In addition, if the first quick-release structure 4 and the mating structure are standardized in the future, it can also achieve universal compatibility between different models of lamp 10 and the bracket, further enhancing the bracket's adaptability and better meeting the needs of lamp 10 replacement and adjustment in diverse photography scenarios, effectively making up for the shortcomings of existing photography light brackets in terms of practicality and adaptability.

[0036] In one embodiment, a plurality of first quick-release structures 4 are arranged at intervals along the length direction of the support rod 2; the position of the first quick-release structure 4 in the length direction of the support rod 2 is adjustable.

[0037] Specifically, from a structural perspective, in this scheme, multiple first quick-release structures 4 are arranged along the length of the support rod 2, and each first quick-release structure 4 maintains a certain interval to form a preset installation position. At the same time, the first quick-release structure 4 has a structural basis for adjusting its position along the length of the support rod 2. Specifically, it can be inferred that the support rod 2 is provided with a suitable position adjustment base structure (such as a slide groove 331 extending along the length direction, a guide rail, or multiple sets of positioning holes). The first quick-release structure 4 is equipped with connecting parts that match the base structure (such as a slider, a buckle that can be inserted into the positioning hole, or a sliding collar), and is usually provided with a positioning locking component (such as a locking bolt or an elastic pin) to fix the first quick-release structure 4 after it is adjusted to the target position, preventing it from shifting on its own, thereby simultaneously realizing the initial state of "arranged at intervals along the length direction" and the functional attribute of "adjustable position".

[0038] From the working principle perspective, the multiple first quick-release structures 4 are arranged at intervals along the length of the support rod 2, which firstly provides multiple preset installation points for the lamps 10, which can directly meet the needs of installing multiple lamps 10 on the support rod 2 at fixed intervals (for example, if 2 or 3 lamps 10 are required according to the shooting scene and the interval is fixed, the corresponding quick-release structure can be directly selected for installation). When it is necessary to adjust the interval of the lamps 10 to adapt to different shooting needs (such as changes in the size of the lamps 10 or adjustments to the fill light range), the positioning locking component is operated (such as loosening the locking bolt or pressing the elastic pin to release the lock), so that the first quick-release structure 4 slides along the basic adjustment structure (slide groove 331, guide rail) on the support rod 2. After moving to the required length position, the positioning component is locked again to fix the first quick-release structure 4, thus completing the position adjustment. This retains the convenience of preset intervals and breaks through the limitations of fixed intervals.

[0039] From a technical perspective, on the one hand, the spaced arrangement along the length solves the problem that a single quick-release structure cannot accommodate the simultaneous installation of multiple lights 10, and the preset intervals provide a quick assembly solution for common shooting scenarios, improving operational efficiency. On the other hand, the adjustable position design greatly enhances the flexibility of the bracket, allowing adjustments to be made based on the number of lights 10, the size of the lights 10 (e.g., adjusting the spacing of long strip lights 10 to avoid obstruction), the size of the subject being photographed (e.g., compact arrangement of lights 10 for close-up shots, dispersed arrangement of lights 10 for panoramic shots), or the desired lighting effects (e.g., adjusting the spacing of lights 10). By adjusting the uniformity and ratio of the fill light, the longitudinal position of the light fixture 10 on the support rod 2 can be precisely adjusted, avoiding the limitation that the bracket can only be adapted to a single scene due to the fixed position of the quick-release structure. At the same time, the adjustable position design eliminates the need to replace the support rod 2 or add additional quick-release components, reducing equipment replacement costs. Moreover, the adjustment process does not require complicated tools (such as only manually loosening and tightening bolts), making it convenient to operate and further improving the practicality and adaptability of the bracket. It effectively makes up for the lack of flexibility in installing multiple light fixtures 10 in existing photography light brackets and better meets the needs of diverse photography scenarios.

[0040] In one embodiment, a pair of first quick-release structures 4 are disposed at the middle position of the support rod 2, and the remaining first quick-release structures 4 are respectively located on both sides of the first quick-release structure 4 at the middle position.

[0041] Specifically, from a structural perspective, the core of this scheme lies in the specific positional layout of the first quick-release structure 4 on the support rod 2, clearly encompassing the dual characteristics of "central positioning and lateral distribution": First, a pair of first quick-release structures 4 are precisely positioned in the center of the support rod 2, and this central position is highly likely to coincide with or be close to the center of gravity of the support rod 2 itself, forming the core benchmark for load bearing; Second, the remaining first quick-release structures 4 are not randomly distributed, but are arranged at intervals towards both ends of the support rod 2 with the central pair of first quick-release structures 4 as the center of symmetry (or benchmark point), presenting an overall layout with the center as the core and the sides extending evenly and symmetrically, while retaining the functional attribute of the first quick-release structure 4 being able to adjust its position along the length of the support rod 2, ensuring a combination of layout flexibility and fixed benchmark.

[0042] From a working principle perspective, considering the characteristic that the support rod 2 can rotate freely around the longitudinal member 12 via the connecting mechanism 3, and the function of the first quick-release structure 4 in supporting the lamp 10, this layout achieves "center of gravity correlation". Achieving rotational stability: When the first quick-release structure 4 in the middle carries the lamp 10, the load acts directly on the vicinity of the center of gravity of the support rod 2, which can minimize the eccentric torque generated by the weight of the lamp 10 on the support rod 2; while when the first quick-release structures 4 on both sides carry the lamp 10, since they are distributed with the center of gravity in the middle as the reference, the loads on both sides can form mutually balanced torques (if the lamp 10 is installed symmetrically, the torques on both sides are equal in magnitude and opposite in direction, directly canceling the eccentric effect; if it is installed asymmetrically, the load can also be made to approach balance by adjusting the position of the quick-release structures on both sides), avoiding the center of gravity of the support rod 2 from shifting due to excessive load on one side; during the rotation adjustment of the support rod 2, this load distribution state around the center of gravity is always maintained, so that the torque that the support rod 2 needs to overcome when rotating is small and the force is more uniform, and after rotating to any angle, the relative position of the load and the center of gravity is stable, and it is not easy to rotate or shift due to torque imbalance.

[0043] Please refer to the following: Figure 3 In one embodiment, the connecting mechanism 3 includes a rotating shaft 31 rotatably connected to the longitudinal member 12, a second quick-release structure 32 connected to the rotating shaft 31 and capable of rotating around the rotating shaft 31, and a second quick-release engaging structure 33 that is inserted into the second quick-release structure 32. The second quick-release engaging structure 33 is connected to the support rod 2. The second quick-release engaging structure 33 is provided with a sliding groove 331, and the second quick-release structure 32 is inserted into the sliding groove 331.

[0044] Specifically, structurally, the connecting mechanism 3 consists of three core components: a rotating shaft 31, a second quick-release structure 32, and a second quick-release mating structure 33. Each component has a clear connection and adaptation relationship: the rotating shaft 31, as the basic rotating component, directly forms a rotatable connection with the longitudinal member 12 (e.g., through bearings, shaft holes, etc.), providing the basis for the entire connecting mechanism 3 to rotate around the longitudinal member 12; one end of the second quick-release structure 32 is fixedly connected to the rotating shaft 31 (or integrated into the design), and can rotate synchronously with the rotating shaft 31 around the longitudinal member 12, while also possessing a plug-in form compatible with the second quick-release mating structure 33; the second quick-release... The disassembly and assembly structure 33 is fixedly connected to the support rod 2 (e.g., by welding or bolting). Its core feature is that it has a sliding groove 331. The size and shape of the sliding groove 331 match the second quick-release structure 32, which can realize the insertion and engagement of the two. The sliding groove 331 usually extends in a specific direction (e.g., the radial direction of the support rod 2, or the direction perpendicular to the axis of the rotating shaft 31) to provide the second quick-release structure 32 with room for movement after insertion. At the same time, each component may also contain positioning and locking components (e.g., locking knobs, elastic blocks on the second quick-release structure 32, or positioning grooves at the end and side wall of the sliding groove 331) to fix the relative position after insertion or adjustment to prevent loosening.

[0045] From the perspective of working principle, the connecting mechanism 3 achieves dual functions through the synergy of "rotation adjustment, quick-release insertion, and sliding groove 331 adaptation": On the one hand, the rotating shaft 31 drives the second quick-release structure 32, the second quick-release mating structure 33, and the support rod 2 to rotate around the longitudinal member 12, directly realizing the angle adjustment of the support rod 2 (such as rotating the support rod 2 from a horizontal to an inclined state), meeting the basic adjustment requirements of the lamp 10 in terms of spatial angle; on the other hand, the sliding groove 331 of the second quick-release structure 32 and the second quick-release mating structure 33 are inserted and mated, which realizes the quick installation and removal of the support rod 2 (when the support rod 2 needs to be replaced, after unlocking, the sliding groove 331 of the second quick-release mating structure 33 is inserted from the second quick-release structure 32). The support rod 2 can be removed by pulling it out, and vice versa for quick installation. The extension direction of the slide groove 331 allows for additional fine-tuning of the support rod 2's position (e.g., when the slide groove 331 extends radially along the support rod 2, the distance between the support rod 2 and the longitudinal member 12 can be fine-tuned; or when the slide groove 331 extends in the rotation direction, it assists in adjusting the rotation angle accuracy of the support rod 2). Simultaneously, after the positioning and locking components are adjusted to the correct position (e.g., after rotating to the target angle, plugging in, or fine-tuning to the target position), they can fix the relative positions of each component, ensuring that the support rod 2 does not rotate or shift unexpectedly during use, and guaranteeing the stability of the lamp 10's position.

[0046] Please refer to the following: Figure 4In one embodiment, the camera light bracket further includes an angle adjustment and locking mechanism 5, which is connected to the rotating shaft 31 and the longitudinal member 12. The angle adjustment and locking mechanism 5 is used to lock the rotating shaft 31 at a preset angle. The angle adjustment and locking operation mechanism 5 includes a handle 51 rotatably disposed on the longitudinal member 12, a drive shaft 52 connected to the handle 51, a pressing structure 53 connected to the drive shaft 52, and a clamping structure 54, wherein the clamping structure 54 is provided with a clamping groove 541. A rotating disk 311 is coaxially provided on the rotating shaft 31 and partially accommodated in the clamping groove 541. The handle 51 can drive the pressing structure 53 to apply pressure to the clamping structure 54 through the driving shaft 52, so that the clamping structure 54 clamps the rotating disk 311, thereby fixing the rotating shaft 31 at a preset angle.

[0047] Specifically, from a structural perspective, the angle adjustment locking mechanism 5 in this scheme, as the core locking component connecting the rotating shaft 31 and the longitudinal member 12, is composed of multiple components working together: the handle 51 adopts a rotating assembly structure (such as being connected to the longitudinal member 12 via a bushing or bearing), and can be manually rotated around its own assembly axis; one end of the drive shaft 52 is fixedly connected to the handle 51 (such as being integrally molded or threaded), and the other end extends to the pressing structure 53 and is linked with it (possibly through a rigid connection or transmission via an inclined plane or cam structure); the pressing structure 53 needs to have pressure transmission capability (such as a pressing block, wedge block, or elastic pressure plate, which can move along the axis of the drive shaft 52 or in a specific direction); the clamping structure 54 is provided with a clamping groove 541 that matches the rotating disk 311 on the rotating shaft 31 (the groove shape matches the outer circumference of the rotating disk 311, such as an arc or V-shape). The rotating disk 311 is coaxially fixed with the rotating shaft 31 (e.g., by welding or keying), and part of its circumferential surface is placed in the clamping groove 541, forming a "clamping groove 541 enveloping a part of the rotating disk 311" fit. At the same time, each component must meet the requirement of continuous power transmission to ensure that the operation of the handle 51 can sequentially drive the drive shaft 52, the pressing structure 53, and the clamping structure 54 to move, and finally act on the rotating disk 311.

[0048] From a working principle perspective, this mechanism achieves angle fixation of the rotating shaft 31 through a continuous process of "manual drive, power transmission, and clamping lock": When it is necessary to adjust the angle of the support rod 2, first rotate the handle 51 in the reverse direction. The handle 51 drives the drive shaft 52 to rotate synchronously, reducing or eliminating the pressure of the pressing structure 53 on the clamping structure 54. The clamping groove 541 of the clamping structure 54 releases the rotating disk 311. At this time, the rotating shaft 31 can rotate freely (driving the support rod 2 to adjust its angle). The rotating disk 311 rotates synchronously with the rotating shaft 31 and always remains partially within the clamping groove 541. After the support rod 2 is adjusted to the preset angle, rotate the handle 51 in the forward direction. The handle 51 drives the drive shaft 52. Power is transmitted to the clamping structure 54, and the drive shaft 52 drives the pressing structure 53 to apply axial or radial pressure to the clamping structure 54, causing the clamping groove 541 of the clamping structure 54 to tighten towards the rotating disk 311. The rotating disk 311 is clamped by the friction (or interference fit force) between the groove wall and the outer circumference of the rotating disk 311. Since the rotating disk 311 and the rotating shaft 31 are coaxially fixed, the rotating shaft 31 cannot continue to rotate after the rotating disk 311 is clamped and fixed, thereby stabilizing and locking the support rod 2 at the preset angle. If the angle needs to be adjusted again, the operation of unlocking by rotating the handle 51 in the opposite direction can be repeated.

[0049] Please refer to the following: Figure 5 In one embodiment, the transverse member 11 is provided with an adapter 111; the longitudinal member 12 is provided with a handle 121.

[0050] Specifically, from a structural perspective, this solution adds two types of functional structures to the core component of the main frame 1 of the photography light bracket: one is an adapter 111, which is fixedly assembled to the horizontal component 11 of the main frame 1 (possibly fixed by welding, threaded connection, or integral molding to ensure connection strength). The adapter 111 needs to have standardized or adaptable connection interfaces (such as internal threaded holes, external threaded posts, snap-fit ​​interfaces, or quick-connect interfaces). The interface specifications can match common photography auxiliary equipment (such as extension rods, fixed bases, crossbar connectors, etc.), and may also implicitly include angle... The structure consists of two parts: a structural base for degree adjustment or rotation (such as a rotary interface with a positioning pin); and a handle 121, which is set on the longitudinal member 12 of the main frame 1 (usually installed in the middle of the longitudinal member 12 or near the operator's grip, and fixed by bolts, injection molding, or nesting). The handle 121 must conform to ergonomic design, may adopt an arc contour, non-slip material (such as rubber coating, surface texture treatment), and have a certain structural strength to withstand the operating forces related to the entire bracket or the longitudinal member 12 (such as the gripping force during handling and adjustment).

[0051] From the perspective of working principle, the adapter 111 expands the lateral function of the main frame 1 through "interface adaptation": when it is necessary to increase the lateral coverage of the photography light bracket (such as installing multiple sets of support rods 2 or light fixtures 10), the extension rod can be connected to the lateral member 11 through the adapter 111 to extend the effective length of the lateral member 11; when it is necessary to fix the bracket in a specific position (such as a tripod or desktop bracket), the lateral member 11 can be connected to the interface of the corresponding fixing device through the adapter 111 to achieve the overall fixation or position adjustment of the bracket; if the adapter 111 has a rotation function, the angle between the lateral member 11 and the connecting parts can also be adjusted by rotation to further expand the spatial layout flexibility of the main frame 1. The function of handle 121 is to assist in the operation of the longitudinal component 12 and the entire bracket by "holding and supporting": When moving the bracket, the operator can easily lift or move the bracket by holding the handle 121 on the longitudinal component 12, avoiding the inconvenience caused by direct contact with the longitudinal component 12 (which may have poor anti-slip properties and sharp edges); when adjusting the angle of the support rod 2 (such as rotating the support rod 2 through the connecting mechanism 3), handle 121 can serve as a stable gripping point. The operator can hold handle 121 with one hand to fix the longitudinal component 12, and adjust the support rod 2 with the other hand, preventing the longitudinal component 12 from rotating or shifting with the support rod 2, thus improving the accuracy and stability of angle adjustment; during daily use or storage of the bracket, handle 121 can also serve as a convenient force point to assist in the unfolding and folding of the bracket.

[0052] In one embodiment, the longitudinal member 12 is provided with a plurality of handle mounting holes 122, and the handle 121 can be selectively mounted in the handle mounting hole 122, so that the position of the handle 121 on the longitudinal member 12 is adjustable.

[0053] Specifically, from a structural perspective, the core of this solution is to set multiple handle mounting holes 122 on the longitudinal component 12. These mounting holes are distributed at preset intervals along the length of the longitudinal component 12 (the interval distance needs to meet the adjustment requirements of different positions, such as 5-10cm increments). The structural form of the mounting holes needs to be compatible with the mounting components of the handle 121 (commonly, holes with internal threads, corresponding to the external thread mounting post at the bottom of the handle 121; or holes with positioning buckles, corresponding to the elastic snap-fit ​​of the handle 121). At the same time, the handle 121 itself has a structure that can be stably connected to the mounting holes (such as threaded mounting seats or retractable buckles), and the number of mounting holes needs to be at least two (to ensure the adjustability of "selective installation"). The size and specifications of each mounting hole are uniform, ensuring that the handle 121 can be stably assembled in any mounting hole without loosening or adaptation deviation.

[0054] From the perspective of working principle, since multiple mounting holes on the longitudinal component 12 are distributed at intervals along the length direction and have uniform specifications, users can select the appropriate mounting hole according to their own operating needs (such as the preference for grip height due to height differences, the force requirements under different operating scenarios) or the usage status of the bracket (such as the bracket's unfolded height, the center of gravity position during transportation): During installation, align the connecting parts of the handle 121 (such as threaded post, buckle) with the selected mounting hole, and complete the fixing by tightening the thread, pressing the buckle, etc.; If it is necessary to adjust the position of the handle 121, simply reverse the operation (such as unscrewing the thread, pressing the buckle to unlock) to remove the handle 121 from the original mounting hole, and then reinstall it into other target mounting holes, so as to change the position of the handle 121 along the length direction on the longitudinal component 12. The whole process does not require additional tools and the operation process is simple.

[0055] From a technical perspective, this solution effectively addresses the issues of poor adaptability and limited operation associated with traditional fixed-position handles 121. The advantages of this solution are: First, it improves user adaptability. Operators of different heights can find a comfortable grip height by adjusting the position of the handle 121 (e.g., taller operators can choose the mounting hole at the top of the longitudinal component 12, and shorter operators can choose the mounting hole at the bottom), avoiding inconveniences such as bending over or tiptoeing caused by a fixed position of the handle 121, and reducing operator fatigue. Second, it enhances scenario adaptability. The function of the handle 121 can be optimized in different usage scenarios (e.g., when adjusting the angle of the support rod 2, the handle 121 can be installed near the connecting mechanism 3 to facilitate force application and fixation of the longitudinal component 12; when moving the bracket, the handle 121 can be installed in the middle of the longitudinal component 12 to match the center of gravity and improve handling stability). Third, it offers strong ease of operation. The position of the handle 121 can be adjusted without tools, and the uniform mounting hole specifications ensure smooth disassembly and assembly, avoiding adjustment difficulties caused by compatibility issues. In addition, the setting of multiple mounting holes does not increase the structural complexity of the longitudinal component 12, nor does it affect its support strength. It significantly improves the practicality of the bracket with low-cost modification, complementing the previous quick-release structure and angle adjustment mechanism, and further improving the overall user experience.

[0056] In one embodiment, the transverse member 11 is provided with a transition position 112, and the transition position 112 is provided with a transition member 7 for detachable connection with the hoisting member 6.

[0057] Specifically, from a structural perspective, this solution clearly defines two core components on the horizontal member 11 of the camera light bracket: a transition position 112 and a transition component 7. The transition position 112 is a pre-designed assembly area on the horizontal member 11, typically possessing structural positioning functionality (e.g., a plane, groove, or boss with positioning holes, ensuring accurate positioning and balanced stress distribution of the transition component 7 after installation). Its position must be designed in conjunction with the load-bearing center of gravity of the horizontal member 11 (usually located in the middle of the horizontal member 11 or near the load concentration point to avoid center of gravity shift during hoisting). The transition component 7 is then assembled on the transition position 112. One end is stably connected to the adapter 112 by a fixing method (such as bolt connection, welding or quick-release buckle) (ensuring load-bearing strength and able to withstand the overall weight of the bracket and lamp 10). The other end is provided with a detachable connection interface that is compatible with external hoisting components 6 (such as hoisting chains, hoisting rods, ceiling hooks, studio hoisting rails, etc.). The interface may be internal or external threaded, hook type, quick-plug or buckle type, and must conform to the general specifications of common hoisting equipment to improve compatibility. At the same time, the adapter component 7 itself may have a lightweight design (such as using aluminum alloy material) to reduce the overall load while ensuring strength.

[0058] From a working principle perspective, the core function of the adapter 112 is to provide a fixed reference and force support point for the adapter component 7, ensuring that the adapter component 7 will not slide or shift along the transverse component 11 after installation, thereby ensuring the overall force balance of the bracket during hoisting. The adapter component 7 acts as a "connecting bridge" between the transverse component 11 and the hoisting component 6. Its detachable interface can be quickly connected to the hoisting component 6 (e.g., the hook of the adapter component 7 is hung on the ceiling ring, or it is fixed by screwing it onto the hoisting rod), realizing the conversion of the installation method of the camera light bracket from traditional ground support to high-altitude hoisting. When it is necessary to disassemble or adjust the hoisting position, it is only necessary to disconnect the interface connection between the adapter component 7 and the hoisting component 6 (e.g., remove the hook or unscrew the thread) to separate the bracket from the hoisting state. If the adapter component 7 and the adapter 112 are also detachably connected (e.g., fixed with bolts), the adapter component 7 with different interface types can be replaced as needed to adapt to different types of hoisting components 6 such as hanging chains and hanging rails, without the need to make structural modifications to the transverse component 11 itself.

[0059] From a technical perspective, this solution effectively solves the problems of existing photography light bracket installation methods being limited (mostly relying on ground support) and unable to adapt to specific scenario needs: First, it significantly expands the installation scenarios of the bracket. By using a suspending method, the bracket can be fixed at high altitudes (such as studio ceilings or live streaming studio overhead tracks), meeting both high-altitude lighting needs (such as soft top lighting for shooting large scenes or full-body portraits) and saving ground space (avoiding ground brackets occupying shooting areas or affecting personnel movement). It is particularly suitable for scenarios with high space utilization requirements, such as photography studios and live streaming studios. Second, the detachable design improves operational flexibility and adaptability. The detachable connection between the adapter component 7 and the suspending component 6 facilitates quick installation and disassembly of the bracket, reducing the need for additional support. The design reduces construction and storage costs, and allows for compatibility with various common hoisting equipment on the market by replacing the adapter component 7 with different interfaces, eliminating the need to design separate brackets for specific hoisting methods and enhancing product versatility. Thirdly, structural stability and safety are guaranteed. The pre-designed adapter position 112 ensures that the adapter component 7 is evenly stressed after installation, preventing the bracket from tilting or falling due to improper connection during hoisting. The stable connection between the adapter component 7 and the adapter position 112 can withstand the weight load of the bracket and the light fixture 10, reducing safety hazards. At the same time, this structure does not interfere with the original functions of the horizontal component 11 (such as the adapter 111) and works synergistically with the quick-release structure and angle adjustment mechanism, further improving the functional system of the photography light bracket and enhancing its overall practicality.

[0060] Secondly, a photographic lighting device is provided, including a lamp 10 and the aforementioned photographic lighting bracket, wherein the lamp 10 is detachably fixed to the photographic lighting bracket.

[0061] This photographic lighting equipment combines the light fixture 10 with the aforementioned photographic lighting bracket, which features multi-dimensional adjustment and quick-release adaptability. By employing a detachable and fixed design for the light fixture 10, it achieves several technical optimizations: Firstly, relying on the plug-in adaptation between the first quick-release structure 4 on the bracket and the first quick-release mating structure of the light fixture 10, and the adjustable spacing and position of the first quick-release structure 4 along the length of the support rod 2, the light fixture 10 can be quickly installed and removed from the bracket without the need for additional tools. This significantly reduces the operation time for replacing and adjusting the light fixture 10, solving the problems of cumbersome and inefficient installation and removal of the light fixture 10 in traditional equipment. Simultaneously, multiple sets of adjustable quick-release structures support… The multiple lights 10 can be flexibly arranged according to needs (such as adjusting the number and spacing of lights 10 according to the shooting scene) to meet the needs of multiple supplementary lights in a single scene and avoid the limitations of single-light supplementary lighting effect; secondly, combined with the rotation adjustment function of the bracket connecting mechanism 3 and the precise locking capability of the angle adjustment locking operation mechanism 5, the lights 10 can rotate freely around the longitudinal component 12 with the support rod 2 and be stably fixed at the preset angle. With the convenient grip of the handle 121, the operator can easily adjust the supplementary lighting direction of the lights 10 (such as overhead supplementary lighting, side supplementary lighting), and there is no risk of displacement after locking, ensuring accurate supplementary lighting angle and solving the problems of difficult angle adjustment and unstable positioning of lights 10 in traditional equipment. The light deviation issue is addressed. Furthermore, the design of the adapter 111 and adapter 7 on the horizontal component 11 of the support allows the equipment to be flexibly adapted to auxiliary components such as extension rods and hoisting components 6. The adapter 111 can expand the horizontal lighting range, adapting to large shooting scenarios (such as indoor panoramic portrait shooting), while the adapter 7 enables high-altitude hoisting installation, saving ground space (such as in live streaming studios and photography studios where space utilization is crucial). This breaks the limitation of traditional equipment relying solely on ground support, expanding the equipment's applicable scenarios. In addition, the multi-position adjustable handle 121 on the vertical component 12 adapts to the gripping needs of operators of different heights, improving equipment handling efficiency. The system improves operational comfort during adjustments, reducing user fatigue. The detachable design of the lamp 10 and bracket facilitates disassembly, storage, and transportation, minimizing storage space and handling costs. Furthermore, the bracket can be repeatedly adapted to different models and specifications of compatible lamps 10 (provided the lamp 10 has a matching quick-release mechanism), eliminating the need to replace the entire system when changing lamps 10. This extends the bracket's lifespan, reduces overall equipment operating costs, and comprehensively addresses the technical issues of weak compatibility, limited practicality, and single application scenarios in existing photographic lighting equipment. It enhances the equipment's adaptability and ease of use in diverse photographic scenarios (such as professional shooting, live streaming lighting, and family photography).
