Description

Technical Field

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

[0002] In recent years, LED film and television lights have become increasingly common in the film and television industry, and their applications are becoming more and more widespread. In some scenarios, multiple LED film and television lights are used together for supplementary lighting. Therefore, staff will install multiple LED film and television lights on the same light fixture bracket to achieve splicing of multiple LED film and television lights.

[0003] In related technologies, each LED film and television light needs to be connected to an independent power cord. However, when multiple LED film and television lights are installed in the mounting space of the light fixture bracket, some power cords need to pass through the mounting space used to install other film and television lights before they can be connected to their corresponding film and television lights. This will result in messy and complicated wiring, and multiple power cords may even become tangled, making it complicated for staff to operate and affecting their work efficiency. Utility Model Content

[0004] This application provides a lamp holder and a film and television lighting system, which can make the overall wiring of the film and television lighting system more organized and reduce the probability of tangling between multiple power lines.

[0005] In a first aspect, embodiments of this application provide a lamp holder, which includes a frame and a junction box;

[0006] The frame has multiple installation spaces, which are arranged at intervals along the circumference of the frame. Each installation space is used to install one film and television light. The junction box has an inlet and multiple outlets. The inlet is used to plug in the main power cord, and the outlets are used to plug in multiple branch power cords one by one. The branch power cords are used to plug in one to one of the multiple film and television lights. One of the frame and the junction box has a mounting post extending along the thickness direction of the frame, and the frame and the junction box are connected through the mounting post.

[0007] The multiple installation spaces are arranged around the junction box, and the multiple outlets of the junction box are arranged one-to-one facing the multiple installation spaces.

[0008] In some embodiments, the plurality of cable outlets are arranged at equal intervals along the surrounding direction of the plurality of installation spaces, and the cable inlet is located between any two adjacent cable outlets among the plurality of cable outlets.

[0009] In some embodiments, the junction box includes a side panel assembly, a top plate, and a bottom plate, with both sides of the side panel assembly connected to the top plate and the bottom plate, respectively.

[0010] The side panel assembly includes four plates that are sequentially interlocked with each other, and three of the plates each have a cable outlet, while the remaining plate has both a cable outlet and a cable inlet.

[0011] In some embodiments, the mounting post protrudes from one side of the frame along the thickness direction.

[0012] In some embodiments, the mounting post is welded to one side of the frame along its thickness direction.

[0013] In some embodiments, the junction box is detachably connected to the mounting post.

[0014] In some embodiments, the junction box is provided with a first snap-fit ​​connector, and the mounting post is provided with a second snap-fit ​​connector;

[0015] The first snap-fit ​​component engages with the second snap-fit ​​component to allow the junction box to be detachably snapped onto the mounting post.

[0016] In some embodiments, the frame is further provided with a limiting member, which is rotatably connected to the frame and is used to limit the video light within the installation space.

[0017] Secondly, embodiments of this application provide a film and television lighting system, which includes, as described above, a lamp bracket, multiple film and television lights, a main power cord, and multiple branch power cords;

[0018] Multiple film and television lights are installed one-to-one in the installation space. One end of the main power cord is used to connect to an external power source, and the other end is plugged into the inlet port. Multiple branch power cords correspond one-to-one with multiple outlet ports. One end of each branch power cord is plugged into its corresponding outlet port, and the other end is plugged into its corresponding film and television light.

[0019] Based on the lamp bracket of this application embodiment, since multiple cable outlets face multiple installation spaces one by one, each power cable will not pass through other installation spaces when it is connected to its corresponding film and television light. This effectively reduces the probability of multiple power cables getting tangled, and makes the overall wiring of the film and television light system more organized, which is convenient for staff to operate and effectively improves the staff's operating efficiency.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] Please refer to the following: Figures 1-4 This application proposes a film and television lighting system 300. In the embodiments of this application, the film and television lighting system 300 includes a film and television light 310, a light fixture bracket 100, a main power cord (not shown in the figure) and branch power cords (not shown in the figure).

[0034] The film and television light 310 is used to emit light. Specifically, the film and television light 310 may include a housing and a COB light source (not shown in the figure). A receiving cavity is formed inside the housing, and the COB light source is housed in the receiving cavity and used to emit light. It can be understood that the COB light source includes a metal substrate and multiple LED chips. The multiple LED chips are packaged on the metal substrate to form a high-density, high-power integrated light source. For example, multiple COB light sources may be included, and the multiple COB light sources are spaced apart in the receiving cavity of the housing. Thus, the film and television light 310 has multiple independent light sources, so that the power can be increased by setting multiple COB light sources. For example, when there are four COB light sources, the film and television light 310 is actually a four-head lamp, and the rated power of the four-head lamp can reach 2500W by setting four COB light sources. This embodiment does not specifically limit the rated power of the film and television light 310.

[0035] The lighting fixture bracket 100 includes a frame 10 and a junction box 20. The frame 10 can be made of metal and can be square frame-shaped. This embodiment does not impose specific limitations on the material and shape of the frame 10. The frame 10 has multiple mounting spaces 10A, which are arranged at intervals along the circumference of the frame 10, and each mounting space 10A is used to mount one video light 310. It is understood that the mounting space 10A has an opening for the video light 310 to be inserted into the mounting space 10A. It is understood that when the video light 310 needs to be installed on the frame 10, the worker can insert the video light 310 into the mounting space 10A through the opening, and when the video light 310 needs to be removed from the frame 10, the worker can remove the video light 310 from the mounting space 10A through the opening.

[0036] The junction box 20 has an inlet 20A and an outlet 20B. Specifically, the inlet 20A is used for the main power cord to be plugged in, that is, one end of the main power cord is used to connect to an external power source, and the other end is plugged into the inlet 20A; there are multiple outlets 20B, and there are multiple branch power cords. The multiple outlets 20B are used for the multiple branch power cords to be plugged in one by one, and the multiple branch power cords correspond one-to-one with the multiple outlets 20B, and are used to be plugged into multiple video lights 310 one-to-one, that is, one end of each branch power cord is plugged into its corresponding outlet 20B, and the other end is plugged into its corresponding video light 310.

[0037] One of the frame 10 and the junction box 20 is provided with a mounting post 30. The mounting post 30 extends along the thickness direction x of the frame 10, and the frame 10 and the junction box 20 are connected by the mounting post 30. For example, the mounting post 30 is provided on the side of the frame 10 facing the junction box 20, and the junction box 20 is connected to the frame 10 by connecting to the mounting post 30; or the mounting post 30 is provided on the side of the junction box 20 facing the frame 10, and the frame 10 is connected to the junction box 20 by connecting to the mounting post 30. This embodiment does not limit this. With this arrangement, the mounting post 30 allows for a gap in the thickness direction x between the junction box 20 and the frame 10, so as to avoid interference between the junction box 20 and the components located on the side of the frame 10 facing the junction box 20 along the thickness direction x, and also to avoid interference between the junction box 20 and the video lamp 310 located in the installation space 10A.

[0038] Multiple installation spaces 10A are arranged around the junction box 20. For example, there are four installation spaces 10A arranged around the junction box 20. Multiple outlet ports 20B of the junction box 20 are arranged one-to-one with the multiple installation spaces 10A. In actual operation, when performing wiring, the operator can first plug the main power cord into the inlet port 20A, and then connect the multiple branch power cords sequentially. That is, plug one end of each branch power cord into an outlet port 20B and the other end into the video light 310, thus completing the wiring operation. In this embodiment, since the multiple outlet ports 20B are arranged one-to-one with the multiple installation spaces 10A, when each branch power cord is connected to its corresponding video light 310, the wire will not pass through other installation spaces 10A. This effectively reduces the probability of tangling between multiple branch power cords, making the overall wiring of the video light system 300 more organized, facilitating operator operation, and effectively improving operator efficiency.

[0039] Please refer to the following: Figures 1-4 In some embodiments, multiple cable outlets 20B are arranged at equal intervals along the surrounding direction of multiple installation spaces 10A, that is, the distance between any two adjacent cable outlets 20B is the same. A cable inlet 20A is located between any two adjacent cable outlets 20B among the multiple cable outlets 20B.

[0040] In this embodiment, by setting multiple outlet ports 20B to be arranged at equal intervals, the spacing between any two adjacent outlet ports 20B is the same, so as to avoid the situation where the spacing between two outlet ports 20B is too small and the two power distribution lines become entangled, and further reduce the probability of entanglement between multiple power distribution lines.

[0041] Please refer to the following: Figures 1-4 Optionally, the installation space 10A and the inlet port 20A each include four, and the lines connecting the centers of the four installation spaces 10A are arranged in a square. The four outlet ports 20B are located at the four corners of the junction box 20.

[0042] It is understandable that the number of film and television lights 310 can be four, and the four film and television lights 310 are installed one by one in the four installation spaces 10A. With this arrangement, one light fixture bracket 100 can install four film and television lights 310, effectively improving the lighting effect of the film and television lighting system 300; and the arrangement of the four cable outlets 20B located at the four corners of the junction box 20 can effectively reduce the risk of the four power cables getting tangled together.

[0043] Please refer to the following: Figure 1 as well as Figures 4-5In some embodiments, the junction box 20 includes a top plate 22, a side plate assembly 21, and a bottom plate 23. The two sides of the side plate assembly 21 are connected to the top plate 22 and the bottom plate 23, respectively. The side plate assembly 21 includes four plates 211, which are sequentially interlocked with each other. That is, each plate 211 has a locking block and a locking slot. The locking block is used to engage with the locking slot of an adjacent plate 211, and the locking slot is used to engage with the locking block of another adjacent plate 211.

[0044] Among the four plates 211, three plates 211 each have an outlet port 20B, and the remaining plate 211 has an outlet port 20B and an inlet port 20A.

[0045] In the actual processing, the workshop can manufacture four identical plates 211, and open outlet ports 20B on three plates 211, and open outlet ports 20B and inlet ports 20A on one plate 211. The four plates 211 are then snapped together and assembled. Finally, the top plate 22 and the bottom plate 23 are connected to the side plate assembly 21 respectively, which facilitates the workshop to manufacture and assemble them.

[0046] In some usage scenarios, the housing of the video light 310 protrudes beyond the mounting space 10A along the thickness direction x, thus interfering with the installation of the junction box 20. Therefore, please refer to [the relevant documentation / reference needed]. Figures 1-4 In some embodiments, the mounting post 30 protrudes from one side of the frame 10 along the thickness direction x, and the mounting post 30 protrudes further along the thickness direction x than the video light 310. The mounting post 30 and the frame 10 can be connected by screws or welding. This embodiment does not impose any limitations on this.

[0047] This design ensures that when workers are installing the junction box 20, there will be no interference between the junction box 20 and the housing of the video light 310, thus ensuring that the junction box 20 can be installed on the mounting post 30.

[0048] Please refer to the following: Figures 1-3 In some embodiments, the mounting post 30 is welded to the frame 10 along one side of its thickness direction x. This arrangement can greatly improve the connection strength between the mounting post 30 and the frame 10, prevent the mounting post 30 from accidentally detaching from the frame 10 due to excessive weight of the junction box 20, and ensure safe use.

[0049] Please refer to the following: Figures 1-4 In some embodiments, the junction box 20 is detachably connected to the mounting post 30. It is understood that if the junction box 20 is too large, it may interfere with the installation of the video light 310 into the mounting space 10A or the removal of the video light 310 from the mounting space 10A.

[0050] Based on this, this embodiment sets the connection between the junction box 20 and the mounting post 30 to a detachable connection, so that when installing or removing the video light 310, the junction box 20 can be removed from the mounting post 30 first, avoiding interference between the junction box 20 and the video light 310. In addition, when the junction box 20 needs to be replaced or repaired, it can also be removed, replaced or repaired, and then reinstalled on the mounting post 30.

[0051] Please refer to the following: Figures 1-4 Optionally, the junction box 20 is provided with a first snap-fit ​​connector 24, and the mounting post 30 is provided with a second snap-fit ​​connector 31. The first snap-fit ​​connector 24 and the second snap-fit ​​connector 31 engage, allowing the junction box 20 to be detachably snapped onto the mounting post 30. This ensures the connection strength between the junction box 20 and the mounting post 30, preventing detachment, and also improves the efficiency of assembly and disassembly of the junction box 20, facilitating operator work.

[0052] Please refer to the following: Figures 1-3 In some embodiments, the frame 10 is further provided with a limiting member 11. The limiting member 11 is rotatably connected to the side of the frame 10 facing the junction box 20 along its thickness direction x. The limiting member 11 can be connected to the frame 10 by a hinge to achieve a rotatable connection between the two, or the limiting member 11 can have a pivot, and the rotatable connection between the limiting member 11 and the frame 10 can be achieved through the cooperation of the pivot with the frame 10. The limiting member 11 is used to confine the video lamp 310 within the installation space 10A.

[0053] In this embodiment, the limiting member 11 limits the position of the video light 310, ensuring good installation stability of the video light 310 within the installation space 10A. This effectively prevents the video light 310 from accidentally detaching from the installation space 10A, improving the safety of personnel using the video light system 300. Simultaneously, the installation of the mounting column 30 prevents interference between the junction box 20 and the limiting member 11.
