Description

Technical Field

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

[0002] A photography light is a device that can provide light for shooting scenes, and the photography light can be used with different types of optical accessories according to actual shooting needs to create different lighting effects, thereby meeting different shooting needs. It is understandable that different types of optical accessories have different weights, and optical accessories of the same type but different sizes also have different weights. Therefore, when a photography light is connected to an optical accessory of different weight, the overall center of gravity of the photography light and the optical accessory will change accordingly.

[0003] In the related art, the connection position between the connecting frame and the photographic light is relatively fixed. Therefore, when the photographic light is installed with optical accessories of different weights, the overall center of gravity position will also change accordingly. This will cause the photographic light with optical accessories to rotate freely. The overall structure of the photographic light and the optical accessories will rotate to a greater extent under the influence of their own gravity, causing the staff to have more effort when they need to control the photographic light to rotate in the opposite direction. For example, after a heavier optical accessory is installed on the front side of the photographic light, the overall center of gravity position will move forward. When the photographic light can rotate freely, the overall structure of the photographic light and the optical accessories will rotate to a greater extent in the clockwise direction under the influence of its own weight. When the staff needs to rotate the photographic light counterclockwise, the torque of the power applied by the staff needs to be larger, which makes the staff more laborious when operating and increases the difficulty of operation for the staff.

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

[0045] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0046] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

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

[0048] A photography light is a device that can provide lighting for a shooting scene, and the photography light can be used with different types of optical accessories according to actual shooting needs to create different lighting effects, thereby meeting different shooting needs. It is understandable that different types of optical accessories may have different weights, or even optical accessories of the same type but different sizes may have different weights. Therefore, when a photography light is connected to an optical accessory of different weight, the overall center of gravity of the photography light and the optical accessory will change accordingly.

[0049] In the related art, the connection position between the connecting frame and the photographic light is relatively fixed. Therefore, when the photographic light is installed with optical accessories of different weights, the overall center of gravity position will also change accordingly. This will cause the photographic light with optical accessories to rotate freely. The overall structure of the photographic light and the optical accessories will rotate to a greater extent under the influence of their own gravity, causing the staff to have more effort when they need to control the photographic light to rotate in the opposite direction. For example, after a heavier optical accessory is installed on the front side of the photographic light, the overall center of gravity position will move forward. When the photographic light can rotate freely, the overall structure of the photographic light and the optical accessories will rotate to a greater extent in the clockwise direction under the influence of its own weight. When the staff needs to rotate the photographic light counterclockwise, the torque of the power applied by the staff needs to be larger, which makes the staff more laborious when operating and increases the difficulty of operation for the staff.

[0050] To solve the above technical problems, please refer to Figure 1-Figure 2 The present application proposes a photographic light device. In an embodiment of the present application, the photographic light device includes a plurality of optical accessories (not shown in the figure) and a photographic light device 100. The photographic light device 100 can be selectively connected to one of the plurality of optical accessories.

[0051] The multiple optical accessories may include reflectors, diffusers, snoots, Fresnel lenses, etc., which can adjust the properties, direction, range, etc. of light. This embodiment does not specifically limit the type and size of the optical accessories.

[0052] The photographic light device 100 includes a photographic light 10 and a connecting frame 20. The photographic light 10 is used to emit light required for shooting scenes, and the photographic light 10 can be selectively connected to one of a plurality of optical accessories, so that the light emitted by the photographic light 10 will be directed to the optical accessories, and then directed to the outside after being changed by the optical accessories to create different light effects. Among them, the photographic light 10 can be provided with a bayonet, and correspondingly, each optical accessory is provided with an interface, and the photographic light 10 and each optical accessory are detachably connected by connecting and cooperating with the bayonet and the interface; it can be understood that the bayonet referred to here can be a more commonly used Bowens bayonet in the art, or a bayonet of different specifications set by various manufacturers, and this embodiment does not limit this.

[0053] The photographic light 10 has a plurality of limiting grooves 11. Specifically, the photographic light 10 may include a lamp housing and a light source. The light source is disposed in the lamp housing and can emit light. The plurality of limiting grooves 11 are formed on the side wall of the lamp housing. The plurality of limiting grooves 11 are sequentially arranged along the front-to-back direction of the lamp housing of the photographic light 10. It should be noted that the front-to-back direction referred to in this embodiment is based on the front shell and the rear shell of the lamp housing, that is, the direction from front to back is the direction from the front shell to the rear shell, and the direction from rear to front is the direction from the rear shell to the front shell.

[0054] The connecting frame 20 serves to connect the photographic light 10 to a light stand (not shown in the figure). Specifically, the connecting frame 20 can be in a U-shape or a V-shape, so that the shape of the connecting frame 20 is relatively regular for easy processing and manufacturing, and the material of the connecting frame 20 can be a metal material such as aluminum alloy, so as to have better structural strength while enhancing the industrial beauty and texture of the connecting frame 20. This embodiment does not specifically limit the shape and material of the connecting frame 20.

[0055] The connecting frame 20 is rotatably connected to the photographic light 10. Specifically, the photographic light 10 can be rotated relative to the connecting frame 20, and can be fixed at the position of the set angle after being rotated to the set angle. For example, in actual operation, when it is necessary to adjust the emission angle of the light of the photographic light 10, the staff can rotate the photographic light 10 relative to the connecting frame 20, and after reaching the desired emission angle, the photographic light 10 can be fixed at the angle position.

[0056] The connecting frame 20 can also move relative to the video light 10 in the front-to-back direction, for example, the connecting frame 20 and the video light 10 can move or slide relative to each other, so that the connecting frame 20 can adjust the specific position of the connection position with the video light 10 in the front-to-back direction.

[0057] The connecting frame 20 is provided with a rotation limiter 30. The rotation limiter 30 may be made of metal to have a strong structural strength. Of course, the rotation limiter 30 may also be made of a strong plastic material. The present embodiment does not specifically limit the material of the rotation limiter 30. The rotation limiter 30 can rotate, so it has a rotation center line and rotates around the rotation center line. The rotation limiter 30 can be selectively arranged in one of the limit slots 11, and can rotate around the rotation center line in the limit slot 11 to have a first state and a second state; the first state of the rotation limiter 30 can be referred to Figure 2 The second state of the rotation limiter 30 can be understood by referring to FIG. Figure 2 Please refer to Figure b in the figure for understanding.

[0058] In the first state, the outer wall of the rotation limiter 30 is in contact with the wall of the limiter groove 11, so that the connecting frame 20 can move a set distance relative to the video light 10 and then be fixed at the position of the set distance. In the second state, there is a gap between the outer wall of the rotation limiter 30 and the side wall of the limiter groove 11, so that the connecting frame 20 can move relative to the video light 10.

[0059] Generally speaking, the bayonet is set on the front side of the lamp housing of the photographic light 10, so each optical accessory is connected to the front side of the photographic light 10. Therefore, in actual use, as the shooting requirements change, when the photographic light 10 is replaced with optical accessories of different weights, the center of gravity position of the whole formed by the photographic light 10 and the optical accessories will change in the front-to-back direction. It can be understood that when the staff needs to rotate the photographic light 10 relative to the connecting frame 20, the gravity of the photographic light 10 and the optical accessories as a whole is actually a resistance. Therefore, when the distance between the center of gravity position of the photographic light 10 and the optical accessories as a whole and the connection position of the connecting frame 20 and the photographic light 10 along the front-to-back direction is too large, the force arm of the resistance will be too long, resulting in too large a torque of the resistance, so that when the staff needs to rotate the photographic light 10 relative to the connecting frame 20, the torque of the power applied by the staff needs to be larger, but the power arm of the staff is usually unchanged, which will result in a larger power applied by the staff, so it will make the staff more laborious.

[0060] Based on this, when it is necessary to reduce the torque of resistance, the connection position of the photographic light 10 and the connecting frame 20 can be made as close as possible to the center of gravity of the photographic light 10 and the optical accessory as a whole in the front-to-back direction to reduce the force arm of resistance. In actual operation, this embodiment can control the rotation limiter 30 to rotate around the rotation center line so that the rotation limiter 30 switches from the first state to the second state, and then the photographic light 10 can be controlled to move relative to the connecting frame 20 in the front-to-back direction; and when the connecting frame 20 needs to be fixed at the position of the set distance after moving relative to the photographic light 10, the rotation limiter 30 can be controlled to rotate around the rotation center line to switch from the second state to the first state, thereby limiting the relative movement of the connecting frame 20 and the photographic light 10 in the front-to-back direction based on the limiting abutment between the rotation limiter 30 and the groove wall of the limiting groove 11.

[0061] The technical solution of the present application can adjust the connection position between the photographic light 10 and the connecting frame 20 along the front-to-back direction by controlling the relative movement of the connecting frame 20 and the photographic light 10 along the front-to-back direction after optical accessories of different weights are installed on the photographic light 10, so that the connection position between the connecting frame 20 and the photographic light 10 along the front-to-back direction is as close as possible to the center of gravity of the photographic light 10 and the optical accessories as a whole, so that the gravitational torque of the photographic light 10 and the optical accessories as a whole is small, so that when the photographic light 10 can rotate freely, the rotation amplitude of the whole formed by the photographic light 10 and the optical accessories is small. Therefore, when the staff operates the photographic light 10 to rotate relative to the connecting frame 20, the torque of the power applied to the photographic light 10 is small, which makes the staff more labor-saving during operation, thereby reducing the difficulty of operation for the staff.

[0062] It should be emphasized that with the development of the film, television and photography industries, the power requirements for the photography light 10 are gradually increasing. On this basis, the weight of the photography light 10 will gradually increase. For example, a photography light 10 with a power of 5KW weighs nearly 40 kilograms or even more than 40 kilograms. Therefore, in this embodiment, the operating difficulty of the staff can be effectively reduced, making the staff more labor-saving.

[0063] At the same time, through the cooperation of multiple limit grooves 11 and the rotating limit piece 30, on the one hand, the video light 10 and the connecting frame 20 can be adjusted in a geared manner. Since the gears are fixed in the geared adjustment form, the staff only needs to select a suitable gear, which is convenient for the staff to operate; on the other hand, when the rotating limit piece 30 is in the first state, the abutment force generated between the outer wall surface of the rotating limit piece 30 and the side wall of the limit groove 11 can effectively prevent the rotating limit piece 30 from switching from the first state to the second state when an external force is mistakenly applied to at least one of the video light 10 and the connecting frame 20, thereby effectively avoiding the video light 10 and the connecting frame 20 from moving in the front-to-back direction due to accidental touch, which is beneficial to improving the stability and safety of the video light 10 during use.

[0064] Please refer to Figure 1-Figure 3 In some embodiments, the rotation limiter 30 includes a main body 31 and a protruding portion 32. The main body 31 is a main body 31 of the rotation limiter 30, and the main body 31 is disposed on the connecting frame 20 and has a rotation center line.

[0065] The protrusion 32 is protruding from the outer wall of the main body 31, that is, the protrusion 32 protrudes in a direction away from the rotation center line. The number of the protrusion 32 can be one or more, and the number of the protrusion 32 is not specifically limited in this embodiment. Among them, the protrusion 32 and the main body 31 can be an integral structure, and the setting of the integral structure is conducive to improving the connection strength between the protrusion 32 and the main body 31, and can also reduce the assembly steps of the two, and improve the manufacturing efficiency of the rotation limiter 30; of course, the protrusion 32 and the main body 31 can also be a split structure, and the connection between the two is achieved by welding or other methods, and this embodiment does not limit this.

[0066] Among them, the rotation limit member 30 has a first state by limiting the abutment between the outer wall surface of the protrusion 32 and the side wall of the limiting groove 11, and the rotation limit member 30 has a second state by having a gap between the outer wall surface of the protrusion 32 and the side wall of the limiting groove 11, and a gap between the outer wall surface of the main body 31 and the side wall of the limiting groove 11.

[0067] It is understandable that if the rotation limit member 30 does not include the protrusion 32, on the one hand, when the rotation limit member 30 is in the second state, it will still be in the second state after rotating 180 degrees around the rotation center line in the limit groove 11 instead of switching to the first state. This will cause the staff to be unable to clearly and unambiguously know that the rotation limit member 30 has successfully switched to the first state when controlling the rotation of the rotation limit member 30, affecting the staff's user experience; on the other hand, the center position of the rotation limit member 30 needs to coincide with the center position of the limit groove 11 so that the rotation limit member 30 as a whole can be limitedly abutted against the side wall of the limit groove 11 after rotation, thereby maintaining the first state, but this form requires too high accuracy in the staff's operation. In actual operation, it is difficult for the staff to ensure that the center position of the rotation limit member 30 coincides with the center position of the limit groove 11.

[0068] Based on this, this embodiment provides a protruding portion 32 protruding from the outer wall of the main body 31, and the outer wall surface of the protruding portion 32 is in contact with the side wall of the limiting groove 11, so as to have at least two effects. On the one hand, when the rotation limiter 30 switches from the second state to the first state, the rotation range of the rotation limiter 30 will be limited to a certain angle range, which is less than 90 degrees. Therefore, when the staff controls the rotation limiter 30 to rotate, when the angle range is exceeded, the protruding portion 32 will contact the side wall of the limiting groove 11 as a whole, so that the rotation limiter 30 can no longer continue to rotate, and the staff can clearly and unambiguously know that the rotation limiter 30 has switched to the first state, so that the staff's use experience can be effectively improved. On the other hand, during the rotation of the rotation limit member 30 of the present embodiment, the main body 31 can always avoid the side walls of the limiting groove 11 and does not abut against the side walls of the limiting groove 11. The rotation limit member 30 can be in the second state only by the abutment of the protrusion 32 against the side walls of the limiting groove 11. In this way, when the staff needs to switch the rotation limit member 30 from the second state to the first state, there is no need to ensure that the center position of the rotation limit member 30 coincides with the center position of the limiting groove 11 in the front-to-back direction. Even if there is a slight deviation between the center position of the rotation limit member 30 and the center position of the limiting groove 11 in the front-to-back direction, the rotation limit member 30 can still be switched from the second state to the first state and maintained in the first state, thereby effectively reducing the operating difficulty of the staff.

[0069] Please refer to Figure 1-Figure 3 Optionally, the protrusions 32 include two, and the two protrusions 32 are centrally symmetrically arranged. In this arrangement, the two protrusions 32 can abut against the side walls of the limiting groove 11, effectively increasing the abutment area between the rotation limiting member 30 and the side walls of the limiting groove 11, thereby improving the limiting abutment effect of the rotation limiting member 30 and the side walls of the limiting groove 11, and reducing the risk of relative movement of the connecting frame 20 and the video light 10 in the front-to-back direction due to accidental contact when the rotation limiting member 30 is in the first state.

[0070] Please refer to Figure 1 , Figure 4 , Figure 5 as well as Figure 6 In some embodiments, the photographic light device 100 further includes a housing 40, a first handle 50, and a second handle 53. The housing 40 may be made of metal or plastic, which is not limited in this embodiment. The housing 40 is connected to the photographic light 10 and the connecting frame 20, that is, the connecting frame 20 is connected to the photographic light 10 through the housing 40.

[0071] The first handle 50 and the second handle 53 can both be arranged in a long strip shape, and both can be made of metal or plastic material, which is not limited in this embodiment. The first handle 50 is arranged through the housing 40 and can rotate relative to the housing 40.

[0072] The first handle 50 is inserted through the housing 40 and fixedly connected to the rotation stopper 30. A clamping block 54 is provided at one end of the first handle 50. It is understandable that the other end of the first handle 50 is exposed outside the housing 40, so that the staff can apply force to the other end of the first handle 50 to make the first handle 50 rotate relative to the housing 40.

[0073] The second handle 53 is passed through the shell 40 and can be rotated relative to the shell 40. A snap-in groove 51 is provided at one end of the second handle 53. It can be understood that the other end of the second handle 53 is exposed outside the shell 40, so that the staff can apply force to the other end of the second handle 53 to make the second handle 53 rotate relative to the shell 40.

[0074] In which, when the clamping block 54 and the clamping slot 51 are in the clamping state ( Figure 6 In the state of Figure a), accordingly, the rotation limit member 30 remains in the first state; while the clamping block 54 and the clamping groove 51 are in a separated state ( Figure 6 b in the figure), the rotation limiter 30 will switch from the first state to the second state. This arrangement can further improve the safety of the use of the photographic light device 100, because when the staff needs to control the movement of the photographic light 10 and the connecting frame 20 in the front-to-back direction, they must first control the second handle 53 to rotate relative to the housing 40, so that the clamping block 54 and the clamping groove 51 are switched from the clamping state to the separation state, and then control the first handle 50 to rotate relative to the housing 40, so that the rotation limiter 30 is switched from the second state to the first state, and then the photographic light 10 and the connecting frame 20 can be moved in the front-to-back direction, thereby preventing the photographic light 10 and the connecting frame 20 from relative movement in the front-to-back direction in an abnormal state.

[0075] Optionally, the locations of the clamping block 54 and the clamping slot 51 can be interchanged, that is, the clamping block 54 is disposed at one end of the second handle 53 , and the clamping slot 51 is disposed at one end of the second handle 53 , which is not limited in this embodiment.

[0076] To improve the convenience of staff, please refer to Figure 1 , Figure 4 , Figure 5 as well as Figure 6 Furthermore, a first gripping portion 52 is provided at the other end of the first handle 50 , and a second gripping portion 55 is provided at the other end of the second handle 53 .

[0077] Wherein, under the driving force of the external force, the first gripping portion 52 and the second gripping portion 55 rotate in opposite directions and approach each other, so that the clamping block 54 can be separated from the clamping groove 51. Figure 6 The operator can understand the figure a and the figure b in the figure, so that the staff can operate the first gripping part 52 and the second gripping part 55 with one hand at the same time, which is convenient for operation.

[0078] For example, the staff can hold the first gripping portion 52 and the second gripping portion 55 with one hand at the same time, and then first grasp the second gripping portion 55 with part of the fingers and apply force to the second gripping portion 55, so that the second handle 53 rotates relative to the housing 40, so that the clamping block 54 and the clamping groove 51 switch from the clamping state to the separation state, and then grasp the first gripping portion 52 with the remaining fingers and apply force to the first gripping portion 52, so that the first handle 50 rotates relative to the housing 40, so that the rotation limiter 30 switches from the second state to the first state. In this way, the staff can achieve single-handed operation, which makes the operation more convenient and quick, and helps to improve the convenience of use for the staff.

[0079] Please refer to Figure 4-Figure 7 In some embodiments, the shell 40 is formed with a first limiting cavity 41, and the cavity side wall of the first limiting cavity 41 is used to limit and abut one end of the first handle 50, so that the first limiting cavity 41 can limit the rotation range of the first handle 50.

[0080] It can be understood that the first limiting cavity 41 has two opposite cavity side walls, and there is a gap between the two cavity side walls of the first limiting cavity 41. In this way, the limiting abutment of the two cavity side walls of the first limiting cavity 41 on the first handle 50 can effectively limit the rotation range of the first handle 50.

[0081] Among them, a first limiting rib is protruding from the surface of the shell 40, and a first limiting cavity 41 is defined by the first limiting rib. In this way, the first limiting cavity 41 can be formed by an integral molding method, which is convenient for manufacturing and production.

[0082] Please refer to Figure 4-Figure 7 In some embodiments, the shell 40 is formed with a second limiting cavity 42, and the cavity side wall of the second limiting cavity 42 is used to limit and abut one end of the second handle 53, so that the second limiting cavity 42 can limit the rotation range of the second handle 53.

[0083] It is understandable that the second limiting cavity 42 has two opposite cavity side walls, and there is a gap between the two cavity side walls of the second limiting cavity 42. In this way, the two cavity side walls of the second limiting cavity 42 limit the second handle 53 and abut against each other, so that the rotation range of the second handle 53 can be effectively limited.

[0084] Among them, the surface of the shell 40 is convexly provided with a second limiting rib, and the second limiting cavity 42 is defined by the second limiting rib. In this way, the second limiting cavity 42 can be formed by an integral molding method, which is easy to manufacture and produce.

[0085] Please refer to Figure 4-Figure 7 In some embodiments, the housing 40 is formed with a first limiting cavity 41 and a second limiting cavity 42. The side wall of the first limiting cavity 41 is used to limit and abut against one end of the first handle 50, so that the first limiting cavity 41 can limit the rotation range of the first handle 50. The housing 40 is formed with a second limiting cavity 42, and the side wall of the second limiting cavity 42 is used to limit and abut against one end of the second handle 53, so that the second limiting cavity 42 can limit the rotation range of the second handle 53.

[0086] It can be understood that the first limiting cavity 41 has two opposite cavity side walls, and there is a gap between the two cavity side walls of the first limiting cavity 41, so that the limiting contact of the two cavity side walls of the first limiting cavity 41 with the first handle 50 can effectively limit the rotation range of the first handle 50; and the second limiting cavity 42 has two opposite cavity side walls, and there is a gap between the two cavity side walls of the second limiting cavity 42, so that the limiting contact of the two cavity side walls of the second limiting cavity 42 with the second handle 53 can effectively limit the rotation range of the second handle 53.

[0087] Please refer to Figure 1 Figure 4 as well as Figure 8 In some embodiments, the connection frame 20 and the video light 10 can move in a sliding manner along the front-rear direction. Specifically, the video light device 100 further includes a sliding assembly 60 , which includes a sliding plate 61 and a sliding rail 62 .

[0088] The sliding plate 61 can be made of metal to have better structural strength, and the sliding plate 61 can be roughly square, so that the shape of the sliding plate 61 is more regular for easy molding. The sliding plate 61 is connected to the side of the housing 40 away from the connecting frame 20, so as to be connected to the connecting frame 20 through the housing 40.

[0089] The slide rail member 62 can be made of metal to have better structural strength, and the slide rail member 62 is extended along the front-to-back direction. The slide rail member 62 is connected to the video light 10 and slidably cooperates with the sliding plate 61 so that the connecting frame 20 can slide relative to the video light 10 along the front-to-back direction. The slide rail member 62 has a plurality of limit grooves 11.

[0090] The rotation limiting member 30 further includes a connecting portion 33 , one end of which is fixedly connected to the main body 31 , and the other end of which is passed through the sliding plate 61 and fixedly connected to the first handle 50 .

[0091] In this embodiment, by limiting the movement of the connecting frame 20 and the photographic light 10 in the front-to-back direction to a sliding form, the connecting frame 20 and the photographic light 10 can move more smoothly relative to each other, and the cooperation between the sliding plate 61 and the sliding rail 62 has a guiding function, thereby improving the accuracy of the movement between the connecting frame 20 and the photographic light 10 in the front-to-back direction.

[0092] Please refer to Figure 1 and Figure 4 In some embodiments, the side wall of the lamp housing of the video light 10 is recessed to form a receiving groove 12, and the slide rail member 62 is embedded in the receiving groove 12. In this way, on the basis of the slide rail member 62 being embedded in the receiving groove 12, the sliding plate 61 matched with the slide rail member 62 will be limited and abutted by the groove side wall of the receiving groove 12, so that it cannot be separated from the slide rail member 62. This configuration is conducive to improving the safety of the connecting frame 20 and the video light 10 when sliding in the front-back direction, and preventing the video light 10 from falling due to the separation of the connecting frame 20.

[0093] Furthermore, the bottom wall of the receiving groove 12 is provided with a positioning rib, and the surface of the slide rail member 62 facing the bottom wall of the receiving groove 12 is provided with a positioning groove, and the positioning rib is positioned and matched with the positioning groove. In this way, the accuracy of the slide rail member 62 being embedded in the receiving groove 12 can be ensured, so that the slide rail member 62 is easily embedded in the receiving groove 12.

[0094] Please refer to Figure 1 , Figure 4 as well as Figure 8 In some exemplary structural forms, the sliding plate 61 includes a plate body 611 and a first sliding portion 612, the plate body 611 is for the connecting portion 33 to pass through, and the two sliding portions are respectively connected to opposite sides of the plate body 611 along its width direction.

[0095] The slide rail member 62 is recessed with two sliding steps 621, and a first sliding portion 612 is correspondingly slidably disposed in one of the sliding steps 621. This is beneficial to improving the sliding accuracy and stability between the sliding plate 61 and the slide rail member 62.

[0096] Please refer to Figure 1 , Figure 4 as well as Figure 8 Furthermore, the sliding plate 61 also includes a second sliding portion 613, which is connected to the middle portion of the plate body 611 along its width direction and is provided with an escape opening for avoiding the rotation limiter 30.

[0097] The surface of the slide rail member 62 facing the plate body 611 is recessed to form a sliding groove 622, wherein the second sliding portion 613 is slidably disposed in the sliding groove 622. In this way, the sliding accuracy and stability between the sliding plate 61 and the slide rail member 62 can be further improved through the cooperation between the second sliding portion 613 and the second sliding groove.

[0098] In some usage scenarios, you need to change the direction of light to meet the current shooting needs. Based on this, please refer to Figure 1 , Figure 4 as well as Figure 5 In some embodiments, the photographic light device 100 further includes a rotating shaft 70, one end of which is passed through the connecting frame 20, and the other end is connected to the photographic light 10, that is, the other end is connected to the shell 40, so as to be connected to the photographic light 10 through the shell 40.

[0099] The video light 10 can rotate relative to the connecting frame 20 through the rotating shaft 70 and can stay at any angle. In this way, when the direction of light needs to be changed, the video light 10 can be controlled to rotate relative to the connecting frame 20, and the video light 10 can stay at a desired angle according to actual needs, which is convenient and flexible to operate, and effectively improves the user experience of the staff.

[0100] Of course, in other embodiments, the rotation form of the photographic light 10 and the connecting frame 20 can also be a gear-adjustable form, and this embodiment does not limit this.

[0101] Please refer to Figure 1 , Figure 4 as well as Figure 5 Furthermore, the rotating shaft 70 includes a shaft body 71 and a shaft sleeve 72. The shaft sleeve 72 may be made of metal to have excellent wear resistance, and the shaft sleeve 72 is sleeved on the shaft body 71 and penetrates the connecting frame 20. In this way, the shaft sleeve 72 can be used to protect the shaft body 71, thereby effectively extending the service life of the rotating shaft 70 and achieving more rotation operations.

[0102] Please refer to Figure 1 , Figure 4 as well as Fig.11 In some embodiments, a disc brake assembly 80 is further included, and the disc brake assembly 80 includes a disc brake pad 81, a first gasket 82 and a second gasket 83.

[0103] The disc brake pad 81 can be made of metal to have better structural strength, and the disc brake pad 81 can be arranged in a circular shape to make the shape more regular and easy to manufacture and produce. The disc brake pad 81 is connected to one end of the rotating shaft 70 away from the connecting frame 20.

[0104] The first gasket 82 and the second gasket 83 are both connected to the connecting frame 20. Exemplarily, the connecting frame 20 may include a frame body 21 and a connecting shell 22. The connecting shell 22 is connected to the shell 40, and the frame body 21 is passed through the connecting shell 22. The first gasket 82 and the second gasket 83 are both accommodated in the connecting shell 22. The disc brake pad 81 is connected to the connecting shell 22 and can rotate relative to the connecting shell 22.

[0105] The first gasket 82 abuts against one side of the disc brake pad 81 along the thickness direction thereof, and the second gasket 83 is disposed on the other side of the disc brake pad 81 along the thickness direction thereof. The second gasket 83 can approach or move away from the first gasket 82 along the thickness direction of the disc brake pad 81 to cooperate with the first gasket 82 to clamp or release the disc brake pad 81.

[0106] Please combine Fig.11 As can be understood from Figure a in the figure, when the second gasket 83 approaches the first gasket 82 along the thickness direction of the disc brake pad 81 and moves to abut the other side of the disc brake pad 81 along its thickness direction, the first gasket 82 and the second gasket 83 can cooperate to clamp the disc brake pad 81 and stop the disc brake pad 81 from rotating, so that the video light 10 stops rotating after rotating at any angle relative to the connecting frame 20; on this basis, please combine Fig.11 As can be understood from the diagram b in the figure, when the second gasket 83 moves away from the first gasket 82 along the thickness direction of the disc brake pad 81, the first gasket 82 and the second gasket 83 no longer clamp the disc brake pad 81, so that the video light 10 can continue to rotate relative to the connecting frame 20. Exemplarily, the disc brake assembly 80 also includes an operating member 84, which is penetrated through the connecting shell 22 and fixedly connected to the second gasket 83. In this way, the staff can control the operating member 84 to drive the second gasket 83 to move, so that the second gasket 83 moves closer to or away from the first gasket 82 along the thickness direction of the disc brake pad 81, which is convenient for operation.

[0107] Thus, through the cooperation of the first gasket 82 and the second gasket 83, the disc brake 81 can be stopped stably and quickly, thereby stopping the rotation of the shaft 70, and the braking method causes less wear on the shaft 70, thereby effectively extending the life of the shaft 70. In addition, the staff can also stop the video light 10 in a relatively simple way, which is easy to operate and effectively improves the staff's use experience.

[0108] Please refer to Figure 1 , Figure 4 , Figure 5 , Fig. 9 as well as- Fig.10In some embodiments, the connection shells 22 include two, and the two ends of the frame 21 along the extension direction thereof are respectively penetrated through the two connection shells 22. The two connection shells 22 include a first connection shell 221 and a second connection shell 222, the housing 40 includes two, and one housing 40 is connected to the first connection shell 221, and the other housing 40 is connected to the second connection shell 222, wherein the first gasket 82 and the second gasket 83 are both accommodated in the first connection shell 221, the disc brake pad 81 is connected to the first connection shell 221, and the operating member 84 is penetrated through the first connection shell 221.

[0109] One of the housing 40 connected to the second connection housing 222 and the second connection housing 222 is provided with a plurality of ribs 43, and the other is provided with a plurality of grooves 2221. The plurality of ribs 43 are distributed in concentric circles and are embedded one by one in the plurality of grooves 2221. In this way, the friction force generated by the abutment between the ribs 43 and the groove walls of the grooves 2221 can be utilized to share the pressure applied by the video light 10 to the rotating shaft 70, thereby reducing the risk of damage to the rotating shaft 70.
