Description

Technical Field

[0001] This application relates to the field of photographic lighting equipment technology, and in particular to a lamp holder and a photographic lamp. Background Technology

[0002] On film sets, lighting fixtures are usually mounted on light fixture brackets. In actual use, in order to achieve a specific lighting effect, the light fixture brackets need to be installed at a high position. In this case, when the user needs to adjust the angle of the light fixture, the user has to climb up to manually adjust the light fixture, which is inconvenient and poses a safety hazard.

[0003] Therefore, in related technologies, the industry has developed electrically adjustable lamp brackets to allow users to adjust the lamp angle electrically without having to climb to a high place, such as electrically adjusting the lamp's tilt angle. However, in some usage scenarios, when the lamp bracket experiences an unexpected power outage, the mounting plate cannot automatically return to its initial position. This prevents the mounting plate from extending vertically downwards into the mounting opening of the lamp's mounting structure for connection, forcing users to tilt the lamp bracket for installation. This inconveniences users and negatively impacts the user experience. Utility Model Content

[0004] This application provides a lamp holder and a photographic light, which allows for manual adjustment of the mounting plate angle to facilitate the user connecting the lamp to the lamp holder.

[0005] In a first aspect, embodiments of this application provide a lamp holder, which includes a frame assembly, a pitch adjustment assembly, and a wrench.

[0006] The frame assembly includes a mounting box, a frame, and a loading / unloading plate. The mounting box has a mounting cavity and an opening communicating with the mounting cavity. The frame is fixedly connected to the mounting box, and the loading / unloading plate is located on the outside of the mounting box. The pitch adjustment assembly includes a pitch drive motor, a worm gear, a transmission gear, and an output shaft. The pitch drive motor, the worm gear, and the transmission gear are respectively installed in the mounting cavity. The output end of the pitch drive motor is drivenly connected to one end of the worm gear, and the worm gear is meshed with the transmission gear. One end of the output shaft is drivenly connected to the transmission gear, and the other end passes through the mounting box and is fixedly connected to the loading / unloading plate. The wrench is used to be inserted into the opening to connect to the other end of the worm gear.

[0007] When an external force is applied to the wrench, the wrench can drive the worm gear to rotate, which in turn causes the transmission gear to rotate, thereby causing the output shaft to drive the loading and unloading plate to rotate.

[0008] In some embodiments, the outer wall surface of the worm has a threaded structure for meshing with the transmission gear, and one end of the worm has a through hole and the other end has an insertion slot;

[0009] The through hole is used for the drive end of the pitch drive motor to pass through, and the insertion slot is used for the wrench to be inserted.

[0010] In some embodiments, the wrench includes an operating part and a plug-in part. The operating part is for a user to grip, and one end of the plug-in part is connected to the operating part, while the other end is used to sequentially insert the through-hole and the insertion slot to engage with the other end of the worm gear.

[0011] In some embodiments, the insertion portion is hexagonal, and the insertion slot is an internal hexagonal slot;

[0012] The plug portion is adapted to be plugged into the internal hexagonal slot.

[0013] In some embodiments, the wrench is detachably mounted to the mounting box.

[0014] In some embodiments, the outer surface of the mounting box is recessed to form a receiving groove for accommodating the wrench component.

[0015] In some embodiments, a clamping spring is also included, which is fixedly installed in the receiving groove and forms a clamping space;

[0016] The wrench is located within the clamping space and is held and fixed by the clamping spring.

[0017] In some embodiments, the receiving groove includes a receiving portion and a latch portion. The receiving portion is used to receive a portion of the wrench component, the clamping spring is fixedly installed in the receiving portion, and the latch portion is connected to the receiving portion to receive the remaining portion of the wrench component.

[0018] And / or, the mounting box is provided with a scratch-resistant protrusion at the opening of the receiving groove, the scratch-resistant protrusion is located on the outside of the clamping spring, and along the protruding direction of the scratch-resistant protrusion, the scratch-resistant protrusion is not lower than the clamping spring.

[0019] In some embodiments, a seal is also included, which is detachably connected to the mounting box to have a connected state and a detached state;

[0020] In the connected state, the seal is connected to the mounting box to seal the opening; in the disassembled state, the seal is detached from the mounting box to expose the opening.

[0021] Secondly, embodiments of this application provide a photographic light, which includes a light fixture bracket and a light fixture as described above. The light fixture is detachably connected to the mounting plate and can rotate with the mounting plate.

[0022] Based on the lamp holder and photographic light of this application embodiment, by providing a through hole on the mounting box, the user can connect the worm gear by inserting a wrench into the through hole. The worm gear can then be rotated by manually turning the wrench, thereby ultimately adjusting the angle of the mounting plate. In this way, even if the lamp holder is powered off, the user can still manually adjust the angle of the mounting plate, which facilitates the subsequent installation of the lamp and lamp holder and effectively improves the user experience.

[0032] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0034] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] On film sets, lighting fixtures are usually mounted on light fixture brackets. In actual use, in order to achieve a specific lighting effect, the light fixture brackets need to be installed at a high position. In this case, when the user needs to adjust the angle of the light fixture, the user has to climb up to manually adjust the light fixture, which is inconvenient and poses a safety hazard.

[0038] Therefore, in related technologies, the industry has developed lamp holders that can electrically adjust the angle of lamps, so that users can adjust the angle of lamps electrically without having to climb to a high place, such as the pitch angle of the lamps.

[0039] However, in some usage scenarios, when the lamp bracket experiences an unexpected power outage, the mounting plate cannot automatically return to its initial position. This prevents the mounting plate from extending into the mounting opening of the lamp's mounting structure in a vertically upward or downward orientation to connect with the mounting structure. Consequently, users need to tilt the lamp bracket to install it, which is inconvenient for users and affects their user experience.

[0040] It should be noted that the outer side of the lamp has a mounting structure that connects with the mounting plate. The mounting structure has an assembly port. During installation, the lamp is laid flat, and the assembly port will be vertically upward. Therefore, if the mounting plate is at an angle to the vertical direction, the mounting plate cannot be inserted into the assembly port and connected to the mounting structure in a vertically downward position. In this case, the user needs to tilt the lamp bracket so that the mounting structure can be inserted into the assembly port and connected to the mounting plate. When the lamp bracket is heavy, this will greatly increase the difficulty of operation for the user.

[0041] To resolve the above issues, please refer to the following: Figures 1 to 5 This application proposes a photographic light. In the embodiments of this application, the photographic light includes a lamp (not shown in the figure) and a lamp bracket 100, and the lamp and the lamp bracket 100 are detachably connected.

[0042] The lighting fixture is used to provide the necessary lighting for the shooting location, and the light source of the fixture can be an LED light source. The connection between the lighting fixture and the lighting fixture bracket 100 can be a detachable connection. The outer side of the lighting fixture is provided with a mounting structure, which has an assembly port. The lighting fixture can be detachably connected to the mounting plate 13 through the mounting structure and can rotate with the mounting plate 13.

[0043] The lamp holder 100 can realize the function of electrically adjusting the lamp angle, such as horizontal adjustment of 540 degrees and tilt adjustment of 270 degrees. This application does not impose specific limitations on the specific adjustment form and adjustment angle. It should be noted that the structure of the lamp holder 100 to realize the electric adjustment of the lamp angle is the prior art, and will not be elaborated on here.

[0044] The lamp holder 100 includes a frame assembly 10, a tilt adjustment assembly 20, and a wrench assembly 30. The frame assembly 10 includes a mounting box 11, a frame 12, and a mounting plate 13. The mounting box 11 has a mounting cavity 111 inside, and the mounting box 11 has an opening 112 that communicates with the mounting cavity 111.

[0045] The frame 12 can be U-shaped, making it regular in shape and easy to manufacture. The frame 12 can be made of metal to ensure good strength and stable support for the lamp. The frame 12 is fixedly connected to the mounting box 11. One end of the frame 12 can pass through the mounting box 11 and extend into the mounting cavity 111, then be threaded into the mounting box 11. This makes the frame assembly 10 more compact. Alternatively, the frame 12 can be fixedly connected to the outer side of the mounting box 11. The mounting plate 13 is used to connect with the mounting structure of the lamp. Specifically, the mounting plate 13 can be inserted into the assembly opening to connect with the mounting structure. The mounting plate 13 is located on the outside of the mounting box 11.

[0046] It should be noted that the frame assembly 10 also includes a receiving shell 15, a rotating shaft, and a connecting plate 14. The other end of the frame 12 passes through the receiving shell 15, and the rotating shaft passes through the receiving shell 15, with its end connected to the connecting plate 14. The connecting plate 14 is located on the outside of the receiving shell 15 and is used to connect with the lighting fixture. The mounting structure for the lighting fixture includes a first mounting structure and a second mounting structure, which are respectively located on two opposite outer sides of the lighting fixture. The first mounting structure is used to connect with the mounting plate 13, and the second mounting structure is used to connect with the connecting plate 14. It is understood that when the angle of the connecting plate 14 needs to be adjusted, the user can apply force to the connecting plate 14 to directly rotate it, thereby directly adjusting the angle of the connecting plate 14.

[0047] The pitch adjustment assembly 20 is used to drive the loading and unloading plate 13 to rotate so as to adjust the pitch angle of the lamp. Specifically, the pitch adjustment assembly 20 includes a pitch drive motor 21, a worm gear 22, a transmission gear 23 and an output shaft 24. The pitch drive motor 21, the worm gear 22 and the transmission gear 23 are respectively installed in the mounting cavity 111.

[0048] The output end of the pitch drive motor 21 is connected to one end of the worm gear 22, which meshes with the transmission gear 23. One end of the output shaft 24 is connected to the transmission gear 23, and the other end passes through the mounting box 11 and is fixedly connected to the mounting plate 13. Exemplarily, the transmission gear 23 may include a worm wheel and a gear set; the worm gear 22 meshes with the worm wheel, the worm wheel is connected to the gear set, and the gear set is fixedly connected to one end of the output shaft 24. It is understood that when the lamp holder 100 is de-energized, the pitch drive motor 21 cannot continue to operate and requires re-energization before it can resume operation.

[0049] The wrench component 30 can be T-shaped and has a regular shape. It can also be made of metal to ensure structural strength and prevent damage. The wrench component 30 is inserted into the port 112 to connect to the other end of the worm gear 22.

[0050] When an external force is applied to the wrench 30, the wrench 30 drives the worm gear 22 to rotate, which in turn causes the transmission gear 23 to rotate, thereby causing the output shaft 24 to drive the loading and unloading plate 13 to rotate. In actual operation, the user can first insert the wrench 30 into the slot 112, connecting the wrench 30 to the other end of the worm gear 22, and then apply force to the wrench 30 to turn it, so that the wrench 30 can drive the worm gear 22 to rotate, ultimately achieving the rotation of the loading and unloading plate 13.

[0051] The technical solution of this application provides a through-hole 112 on the mounting box 11, allowing the user to connect the wrench 30 to the worm gear 22 by inserting it into the through-hole 112. The worm gear 22 can then be rotated by manually turning the wrench 30, thereby adjusting the angle of the mounting plate 13. In this way, even if the lamp bracket 100 is powered off, the user can still manually adjust the angle of the mounting plate 13, which facilitates the subsequent installation of the lamp and the lamp bracket 100 and effectively improves the user experience.

[0052] Please refer to the following: Figures 1 to 2 In some embodiments, the lamp holder 100 further includes a seal 50, which is detachably connected to the mounting box 11 to have a connected state and a disassembled state.

[0053] In the connected state, the seal 50 is connected to the mounting box 11 to seal the opening 112. In the disassembled state, the seal 50 is detached from the mounting box 11, exposing the opening 112.

[0054] Thus, when the user needs to manually adjust the angle of the mounting plate 13 using the wrench 30, the seal 50 can be switched from the connected state to the disassembled state, exposing the opening 112. The wrench 30 can then be inserted into the opening 112 to connect with the worm gear 22. After manually adjusting the angle of the mounting plate 13, the seal 50 can be switched from the disassembled state to the connected state, thus sealing the opening 112 to prevent water, dust, and other impurities from entering the mounting cavity 111, effectively providing a sealing effect.

[0055] Please refer to the following: Figures 1 to 2 In some embodiments, the wrench 30 is detachably mounted to the mounting box 11. This allows the user to easily reassemble the wrench 30 after use, preventing its loss. When the user needs to use the wrench 30, it can be directly removed from the mounting box 11, making the operation convenient and quick. This is especially beneficial when the user is outdoors using supplemental lighting, as they can directly remove the wrench 30 from the mounting box 11 without having to search for tools elsewhere, significantly improving the user experience.

[0056] Please refer to the following: Figures 1 to 3 Furthermore, a receiving groove 113 is recessed on the outer surface of the mounting box 11 for accommodating the wrench component 30. In this way, the wrench component 30 can be accommodated by the receiving groove 113, which effectively reduces the risk of the wrench component 30 accidentally detaching from the mounting box 11. Moreover, compared to the form in which the wrench component 30 is directly connected to the outer surface of the mounting box 11, the overall size of the wrench component 30 and the mounting box 11 can be reduced.

[0057] Please refer to the following: Figures 1 to 3 In some embodiments, the lamp holder 100 further includes a clamping spring 40, which can be a metal spring. The clamping spring 40 forms a clamping space 41. It is understood that the clamping spring 40 has excellent elastic deformation properties. When the clamping spring 40 is subjected to force, it can undergo elastic deformation to increase the clamping space 41. When the clamping spring 40 is not subjected to force, it can return to its original shape to decrease the clamping space 41.

[0058] The clamping spring 40 is fixedly installed in the receiving groove 113, for example, by means of a threaded connection between the clamping spring 40 and the mounting box 11. The wrench 30 is disposed in the clamping space 41 and is clamped and fixed by the clamping spring 40. This arrangement further enhances the firmness of the wrench 30 installed on the mounting box 11, and when the user needs to remove the wrench 30, the wrench 30 will automatically press against the clamping spring 40, thereby increasing the clamping space 41, allowing it to be quickly released from the clamping space 41, making operation very convenient.

[0059] To facilitate the user's removal of the wrench part 30 from the receiving slot 113, please refer to the following: Figures 1 to 3 In some embodiments, the receiving groove 113 includes a receiving portion 1131 and a handle portion 1132, with the handle portion 1132 communicating with the receiving portion 1131.

[0060] The receiving portion 1131 is used to receive the wrench part 30, that is, to receive the insertion portion 32 of the wrench part 30, and the clamping spring 40 is fixedly installed in the receiving portion 1131. The handle portion 1132 is used to receive the remaining part of the wrench part 30, that is, the operating portion 31 of the wrench part 30. In actual operation, when the user needs to remove the wrench part 30 from the receiving slot 113, his / her finger can be inserted into the handle portion 1132, and then the operating portion 31 of the wrench part 30 can be turned to tilt it, and then the wrench part 30 can be pulled out, which facilitates the user's operation.

[0061] Please refer to the following: Figures 1 to 3 In some embodiments, the mounting box 11 has a scratch-resistant protrusion 114 at the opening of the receiving groove 113, and the scratch-resistant protrusion 114 is located on the outside of the clamping spring 40. This arrangement reduces the probability of the user coming into contact with the clamping spring 40, thereby effectively preventing the user from being scratched by the clamping spring 40 and ensuring the safety of the user when taking out and putting away the wrench 30.

[0062] Please refer to the following: Figures 1 to 2 as well as Figures 4 to 6 In some embodiments, the outer wall surface of the worm 22 has a threaded structure 223 for meshing with the transmission gear 23, for example, with the worm wheel of the transmission gear 23. One end of the worm 22 has a through hole 221 and the other end has an insertion slot 222.

[0063] The through hole 221 is used for the drive end of the pitch drive motor 21 to pass through, and the insertion slot 222 is used for the wrench 30 to be inserted. In this way, when the wrench 30 is inserted into the insertion slot 222, the wrench 30 can abut against the side wall of the insertion slot 222. Then, when the user applies force to turn the wrench 30, the wrench 30 can rotate along its own axis, thereby driving the worm gear 22 to rotate. The structure is simple and easy to operate.

[0064] In other embodiments, a connector may be provided on the outer surface of the worm 22, and a wrench 30 may be inserted into the through 112 to be fixedly connected with the connector. Then, by the user applying force to the wrench 30, the wrench 30 drives the connector to rotate around the axis of the worm 22, thereby realizing the rotation of the worm 22 along its axis. This embodiment does not limit this.

[0065] Please refer to the following: Figures 1 to 2 as well as Figure 4In some embodiments, the wrench component 30 includes an operating part 31 and a plug-in part 32, with one end of the operating part 31 connected to one end of the plug-in part 32. It is understood that the operating part 31 and the plug-in part 32 are connected to form a T-shaped structure.

[0066] The operating part 31 is for the user to grip, and the other end of the insertion part 32 is used to sequentially insert the through-hole 112 and the insertion slot 222. With this configuration, the user can grip the operating part 31 and then apply force to the operating part 31, causing the insertion part 32 to rotate, which in turn drives the worm gear 22 to rotate.

[0067] Please refer to the following: Figures 1 to 2 as well as Figure 4 Optionally, the insertion part 32 is hexagonal, and the insertion slot 222 is an internal hexagonal slot, resulting in a relatively regular structure. The insertion part 32 is adapted to be inserted into the internal hexagonal slot.

[0068] In this way, the six outer surfaces of the plug part 32 can engage with the six slotted sides of the internal hexagonal socket, resulting in more contact surfaces. This helps to reduce the chance of the wrench part 30 slipping off during the user's operation of the wrench part 30.
