[0027] The serial numbers assigned to the components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0028] Please refer to Figure 1 and Figure 2 , in the embodiment of the present application, a lamp holder is provided. The lamp holder includes a control box 1, a lamp fixture mounting bracket 2, and a cable assembly (not shown); the control box 1 is connected to the lamp fixture mounting bracket 2, and the lamp fixture mounting bracket 2 can rotate relative to the control box 1; on the side of the lamp fixture mounting bracket 2 away from the control box 1, there is a mounting member 3 for mounting a lamp fixture; a first accommodation cavity 41 is provided in the control box 1, a second accommodation cavity 42 is provided in the lamp fixture mounting bracket 2, the cable assembly is disposed in the first accommodation cavity 41 and the second accommodation cavity 42, and the cable assembly is used to provide electrical connection for the lamp fixture.

[0029] The lamp holder in the embodiments of the present application is used to carry a lamp and provide drive for the movement of the lamp. This drive can be that an operator manually operates the lamp holder to perform operations including but not limited to rotation and movement, so that the lamp provides specified light at a specified position and in a specified direction; this drive can also be that the operator sends a control instruction to the lamp holder based on an electronic drive device such as a motor provided on the lamp holder, and the lamp holder automatically executes the corresponding operation according to the control instruction, so that the lamp provides specified light at a specified position and in a specified direction. Specifically, sending a control instruction to the lamp holder can be achieved through a handle communicatively connected to the lamp holder, or by setting corresponding touch buttons on the lamp holder and initiating the control instruction based on the touch buttons.

[0030] To achieve the above object, the structure of the lamp holder in the embodiments of the present application includes a control box 1 and a lamp mounting bracket 2. Among them, the control box 1 and the lamp mounting bracket 2 can be rotatably connected to each other, that is, the control box 1 and the lamp mounting bracket 2 can rotate relative to each other, and it can be realized that when the control box 1 does not move, the lamp mounting bracket 2 rotates relative to the control box 1, so that the lamp mounting bracket 2 can drive the lamp thereon to move following the movement of the lamp mounting bracket 2. Among them, a motor for driving the lamp mounting bracket 2 to rotate relative to the control box 1 can be provided in the control box 1.

[0031] To fix the lamp, on the side of the lamp mounting bracket 2 away from the control box 1, a mounting member 3 is provided. The mounting member 3 can perform an assembly operation on the lamp, so that the lamp is relatively fixed on the mounting member 3. Then, through corresponding operations on the lamp holder and the lamp, the lamp can emit specified light at a specified position and in a specified direction. In addition to the rotatable connection between the control box 1 and the lamp mounting bracket 2, the mounting member 3 on the lamp mounting bracket 2 can also perform pitching rotation, so that the rotation of the lamp in the pitching direction can be further realized to adjust the light-emitting direction of the lamp.

[0032] To avoid the influence of direct cable connection to the lamp on the lamp holder, please continue to refer to Figure 2In the embodiment of the present application, the control box 1 and the lamp mounting frame 2 of the lamp stand are respectively provided with a first accommodating chamber 41 and a second accommodating chamber 42, and the first accommodating chamber 41 and the second accommodating chamber 42 are used to accommodate the cable assembly in the embodiment of the present application. The first accommodating chamber 41 provided in the control box 1 can be integrally formed based on the shell of the control box 1, and the second accommodating chamber 42 can also be integrally formed based on the shell of the lamp mounting frame 2. Specifically, the first accommodating chamber 41 can be completely built into the control box 1 without being exposed, or it can be embedded in the first accommodating chamber 41, so that the first accommodating chamber 41 can have an opening 211 on any surface of the control box 1; the second accommodating chamber 42 is set in the same way. By completely building the first accommodating chamber 41 into the control box 1 without being exposed, the cable assembly can be protected to the maximum extent, and by setting the first accommodating chamber 41 to be partially exposed in the control box 1, the assembly of the cable assembly and the subsequent maintenance of the cable assembly can be facilitated.

[0033] The cable assembly in the embodiment of the present application includes but is not limited to providing a power supply circuit for the lamp, or providing a control circuit for the lamp, and the power supply circuit and the control circuit can be combined to form an integrated circuit. Based on the cable assembly in the embodiment of the present application, the lamp can be adjusted, specifically, the brightness, color and other lighting conditions of the lamp can be adjusted.

[0034] By placing the cable assembly inside the first accommodating cavity 41 and the second accommodating cavity 42, it is possible to effectively avoid cable entanglement and limit the movement of the lamp stand when the cable is directly connected to the lamp, thereby reducing the risk of damage to the lamp and the lamp stand.

[0035] In some alternative embodiments, please refer to Figure 3, To facilitate the assembly of the cable assembly and further reduce the impact of the cable assembly on the movement of the lamp holder, the cable assembly may specifically include a first cable and a second cable. The first cable is disposed in the first accommodation cavity 41, and the second cable is disposed in the second accommodation cavity 42; the lamp holder further includes a first interface 51, and the first interface 51 is fixedly disposed in the second accommodation cavity 42; one end of the first cable is connected to the control box 1, and the other end is connected to the first interface 51, and the second cable is connected to the first interface 51. That is to say, the cable assembly in the embodiment of the present application can be not only an integrated cable, but also a cable assembly formed by splicing multiple cables. The splicing method can be based on the structure of the lamp holder, and the cable assembly is divided into a first cable and a second cable. The first cable is built in the first accommodation cavity 41, and the second cable is correspondingly built in the second accommodation cavity 42. Since the first accommodation cavity 41 and the second accommodation cavity 42 are respectively disposed on different components, in order to achieve electrical connection between the first cable and the second cable in this structure, a first interface 51 is also fixedly disposed in the second accommodation cavity 42. The first interface 51 is respectively connected to the first cable and the second cable, thereby indirectly achieving electrical connection between the first cable and the second cable.

[0036] The first interface 51 may include a socket. The first cable and the second cable can be respectively inserted into the first interface 51 through matching plugs; through the cooperation of the socket and the plug, disassembly and assembly operations can be provided for the first cable and / or the second cable, which is convenient for subsequent maintenance.

[0037] In addition, please refer to Figure 4 and Figure 5 , the first interface 51 may further include a circuit board 511. The circuit board includes a first electrical connection portion 512 and a second electrical connection portion 513 that are electrically connected to each other; one end of the first cable is connected to the control box 1, and the other end is connected to the first electrical connection portion 512; the second cable is connected to the second electrical connection portion 513. The first cable and the second cable can be respectively fixedly connected to the circuit board. The specific connection method is that the first cable and the second cable respectively form electrical connections with the first electrical connection portion 512 and the second electrical connection portion 513 provided on the circuit board, thereby indirectly achieving electrical connection between the first cable and the second cable.

[0038] In some alternative embodiments, to further enhance the convenience of subsequent maintenance operations and reduce the impact of the cable assembly on the lamp holder at the bending point of the lamp holder, the lamp mounting bracket 2 includes a cross arm 21 and longitudinal arms 22 respectively disposed at both ends of the cross arm 21. The cross arm 21 is rotatably connected to the control box 1. The longitudinal arms 22 extend in a direction away from the control box 1, and a mounting member 3 is formed at the end of the longitudinal arm. The lamp holder further includes a second interface 52 fixedly disposed in the second accommodation cavity 42. The second cable includes a disassembly and assembly line 53 and an extension line. The disassembly and assembly line 53 is located at the cross arm 21 and connects the first interface 51 and the second interface 52. The extension line extends from the second interface 52 to the end of the longitudinal arm 22 away from the cross arm 21. In order to achieve the installation of the lamp, the structure of the lamp mounting bracket 2 includes a pair of longitudinal arms 22 for forming the mounting member 3 and a cross arm 21 connecting the longitudinal arms 22. Among them, the cross arm 21 and the control box 1 can rotate relative to each other. The cross arm 21 can drive the longitudinal arms 22 to rotate in the corresponding direction. The longitudinal arms 22, as the mounting member 3, can further drive the lamp to rotate in the corresponding direction, so as to realize the rotation of the lamp without rotating the control box 1, so that the lamp can emit light at a specified position and in a specified direction. The function of the second interface 52 is to connect the further divided second cable, improve the disassembly and assembly freedom of the second cable, further divide the second cable into a disassembly and assembly line 53 and an extension line. According to the distribution of the cross arm 21 and the longitudinal arms 22, the second accommodation cavity 42 respectively has a part located at the position of the cross arm 21 and a part located at the position of the longitudinal arms 22. The disassembly and assembly line 53 is disposed in the part of the second accommodation cavity 42 located at the cross arm 21. The disassembly and assembly line 53 connects the first interface 51 and the second interface 52. In this way, the disassembly and assembly operations of the disassembly and assembly line 53 can be performed without affecting the extension line, improving the maintainability of the lamp holder.

[0039] In addition, in the embodiments of the present application, since the lamp mounting bracket 2 includes a pair of longitudinal arms 22 arranged in pairs, the second accommodation cavity and the second cable can also correspondingly include two groups, which are respectively located in the two longitudinal arms 22 and can be connected to the lamp from the sides of the two longitudinal arms 22.

[0040] In some alternative embodiments, please refer to Figure 6 , to further improve the disassembly and assembly convenience of the disassembly and assembly line 53, the cross arm 21 may specifically include a cross arm 21 body and a cover plate 7. The cross arm 21 body is provided with an opening 211 corresponding to the position where the disassembly and assembly line 53 is located. The cover plate 7 is correspondingly disposed at the opening 211 and is detachably connected to the cross arm 21 body. By providing the opening 211 on the cross arm 21, the facilities inside the cross arm 21 can be conveniently maintained from the opening 211, including but not limited to replacement, repair, etc.; the cover plate 7 is detachably disposed at the opening 211, which can close the opening 211 and improve the convenience of switching between the closed and open states.

[0041] In some optional embodiments, please continue to refer to Figure 3 In order to facilitate the tightness adjustment of the internal wiring and avoid loosening of the connection, the disassembly and assembly line 53 can specifically include an elastic line, which can adapt to the internal space of the second accommodating cavity 42 to enhance the stability of the connection between the control box 1 and the lamp mounting frame 2.

[0042] In some optional embodiments, please continue to refer to Figure 3 and Figure 5 The control box 1 and the lamp mounting frame 2 can rotate relative to each other. In order to prevent the connection between the two from being loosened, an elastic seal 6 is provided at the connection between the control box 1 and the lamp mounting frame 2. The elastic seal 6 prevents the control box 1 and the lamp mounting frame 2 from being loosened as they rotate, and can further improve the sealing performance of the first accommodating cavity 41 and the second accommodating cavity 42, thereby effectively protecting the cable assembly.

[0043] The specific composition of the elastic sealing member 6 may include an elastic sleeve 61 and a locking member 62, wherein the elastic sleeve 61 may include a silicone sleeve, which may be arranged along the rotation axis between the control box 1 and the lamp mounting bracket 2, and embedded in the first accommodating cavity 41; the locking member 62 may include a locking nut, which is fixedly connected by the locking nut to lock the silicone sleeve.

[0044] The location where the elastic seal 6 is disposed may correspond to the opening 211 on the cross arm 21 . After removing the cover plate 7 , the elastic seal 6 may be disassembled and assembled, and operations such as replacing an aged silicone sleeve may be implemented.

[0045] In some alternative embodiments, please refer to Figure 7 and Figure 8 In order to better accommodate the cable assembly, a plurality of wire holes 43 are provided in the first accommodating chamber 41 and / or the second accommodating chamber 42. The wire holes 43 are interconnected, and the cable assembly passes through the wire holes 43 in sequence to route in the first accommodating chamber 41 and / or the second accommodating chamber 42. The first accommodating chamber 41 and the second accommodating chamber 42 provide space for accommodating the cable assembly, and in order to further accommodate the cable assembly, wire holes 43 can also be provided in the first accommodating chamber 41 / or the second accommodating chamber 42, so that the cable can be routed through the wire holes 43, which can prevent the cable from shaking in the accommodating chamber due to lack of restraint. The size of the wire hole 43 varies. The larger the size, the more convenient it is for the cable assembly to be routed, and the smaller the size, the more it can limit the shaking of the cable assembly. Specifically, at least part of the wire hole 43 can form an interference fit with the cable assembly, and the flexible shell of the cable itself is used to limit the movement of the cable relative to the wire hole 43.

[0046] The wire passing hole 43 can be realized by directly setting notches on various components of the lamp holder, including but not limited to the reinforcing rib structure inside the lamp holder; the wire passing hole 43 can also be realized by the cooperation of two or more components. For example, the wire passing hole 43 can be realized by the cooperation of the circuit board fixedly arranged in the second accommodating cavity 42 and the inner wall of the second accommodating cavity 42. The wire passing hole 43 can clamp and fix the dismountable wire 53, and by removing the circuit board, this clamping and fixing can be removed, so as to realize the disassembly and installation operations of the dismountable wire 53.

[0047] In some alternative embodiments, please continue to refer to Figure 1 and Figure 7 , in order to improve the compatibility of the lamp holder, an exposed first connection terminal 81 can also be arranged on the control box 1, and the first connection terminal 81 is electrically connected to the cable assembly; and / or, an exposed second connection terminal 82 can also be arranged on the mounting member 3, and the second connection terminal 82 is electrically connected to the cable assembly. By arranging the exposed first connection terminal 81 on the control box 1, it can be connected to an external control device, and through the cable assembly, the control signal can be transmitted to the lamp. And by arranging the exposed second connection terminal 82 on the mounting member 3, it is used to connect to the lamp, and the circuit of the lamp itself can be connected to the lamp holder through the second connection terminal 82 arranged on the mounting member 3, so that more lamps can be adapted, and the disassembly and assembly of the lamps are more convenient.

[0048] In addition, in the case where the first connection terminal 81 and the second connection terminal 82 are not arranged, the power supply, controller, etc. required by the lamp can also be directly connected to the lamp through this cable assembly. In this case, the power supply, controller, and lamp can be directly designed to be integrated with the lamp holder.

[0049] In some alternative embodiments, a third connection terminal 83 can also be arranged on the control box 1, and the third connection terminal 83 is used to be connected in series with the first connection terminal 81 on the control box 1 of other lamp holders. Arranging the third connection terminal 83 can be connected in series with the first connection terminal 81 on the control box 1 of other lamp holders, so that the lamps on multiple lamp holders can be powered by one power supply, and the lamps on multiple lamp holders can also be controlled by one controller.

[0050] For the lamp holder provided by the embodiment of the present application, by arranging the cable assembly inside the first accommodating cavity and the second accommodating cavity of the lamp holder, the winding of the cable due to the movement of the lamp holder when the cable is exposed is avoided, thereby effectively reducing the movement limitation of the cable on the lamp holder and reducing the damage risk of the cable to the lamp and even the lamp holder.

[0051] The above uses specific examples to elaborate on the present utility model, which is only used to help understand the present utility model and is not intended to limit the present utility model.
