[0002] As a lighting tool, lamps are widely used in road facilities, office spaces, furniture lighting and other fields. Lamps with different structures and forms are suitable for installation in different application places. In indoor places, lamps represented by direct-down LED lamps are mostly installed on the ceiling and other installation bases.

[0003] However, in the process of installing the lamps to the installation foundation, the problem of inconvenient wiring of the lamps often occurs. This is because the wiring and layout of the lamps in the engineering design and construction are constructed before the lamps are selected. At the same time, most manufacturers shorten the wiring of lamps in order to reduce costs while meeting safety regulations. Therefore, when customers are wiring the lamps and power supplies, they often need to increase the power supply wiring or readjust the installation position of the lamps to solve the wiring of the lamps, which will increase the installation cost or affect the lighting effect of the lamps. Especially in a small space or in some environments that require the volume occupied by the lamps, the random extension or bending of the wires will cause inconvenience in installation. In addition, the lamp structures and the locations of the lamp outlets of different companies are different, which also adds difficulties for customers when selecting lamps.

[0044] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0046] Embodiment 1:

[0047] Please refer to the attached Figure 1-8 The present embodiment provides a wire installation structure 10, which can realize the rotation of the wire 1 relative to the installation device, can meet the requirements of different wiring positions, is convenient for users to use, and is conducive to the installation of the installation device in a small space.

[0048] Specifically, Figure 1 An exploded schematic diagram of the wire installation structure is given. Figure 1 As shown, the wire installation structure 10 includes a wire 1 , a first base 2 and a second base 3 .

[0049] Figure 2 A schematic diagram of the structure of the wire is given. The wire 1 includes a wire body 11, a wire support 12 and a wire input portion 13. The wire input portion 13 is formed by the wire body 11 passing through the wire support 12 and then bending. In this embodiment, the wire support 12 is integrally injection molded with the wire body 11 and the wire input portion 13. It can be understood that in some embodiments, the wire 1 can also be formed by installing the wire support 12 using a conventional power cord.

[0050] The wire support 12 is provided with a first rotating part 121, and the wire body 11 passes through the first rotating part 121 and the bent part forms the wire input part 13, or the part bent relative to the wire body 11 and connected to the first rotating part 121 is the wire input part 13. The wire input part 13 is used to form an electrical connection with the device, and the first rotating part 121 is used to connect with the second base 3 and realize the rotation function. The wire input part 13 can be composed of a wire core with the outermost common insulation layer stripped off.

[0051] Figure 3 A schematic diagram of the structure of the first base is given. The first base 2 is used to be fixedly connected to the lamp housing (the housing of the lighting device, not shown in the figure), and the first base 2 includes a bottom plate 21 and a side plate 22 extending upward from the bottom plate 21. An accommodating cavity 210 is formed between the bottom plate 21 and the side plate 22. The bottom plate 21 is provided with a first slot 23, and the first slot 23 is used for the wire input part 13 to pass through, so that the wire input part 13 is electrically connected to the device.

[0052] Figure 4A structural schematic diagram of the second base is given. After the second base 3 is combined with the first base 2, the first rotating part 121 of the wire bracket 12 is limited. Specifically, the second base 3 is a block structure as a whole, and can be embedded and installed in the accommodating cavity 210. The second base 3 is provided with a second slot body 31, and the second slot body 31 is arranged corresponding to the first slot body 23, so that after the first base 2 and the second base 3 are assembled, the first slot body 23 and the second slot body 31 are interconnected. Furthermore, the overall thickness of the second base 3 is preferably adapted to the height of the side plate 22, so that when the second base 3 is embedded and installed with the first base 2, the outer surface does not protrude from the first base 2, and the thickness of the first base 2 and the second base 3 when combined is reduced as much as possible, so as to achieve the purpose of streamlining the volume.

[0053] Figure 5 and Figure 6 The structural diagrams of the wire installation structure in different states are given respectively. Figures 1 to 6 When the wire installation structure 10 is installed, the first base 2 is used to be fixedly connected with the lamp housing. The wire input part 13 passes through the second slot body 31, the first slot body 23 and the lamp housing in sequence, and the first rotating part 121 is installed at the second slot body 31. Then the second base 3 is moved close to the first base 2 and assembled. At this time, the first rotating part 121 is limited between the first base 2 and the second base 3, and the first rotating part 121 can rotate relative to the second base 3. Therefore, the wire 1 can be installed on the lamp housing and rotated relative to the lamp housing through the cooperation between the wire bracket 12, the first base 2 and the second base 3, so as to adapt to different wiring positions. In addition, due to the relative bending between the wire input part 13 and the wire main body 11, the wire main body 11 can fit the outside of the lamp housing as much as possible, or even be parallel to the outside of the lamp housing, so as to avoid the wire 1 protruding relative to the device, thereby reducing the installation volume required for the device and solving the problem of installing the device in a small space.

[0054] In some embodiments, the first rotating portion 121 has a first central axis L1, and the wire body 11 has a second central axis L2. The first central axis L1 and the second central axis L2 intersect to form a 90° angle, so that it can be applied to most device housings and make the wire body 11 completely parallel to the outer side of the lamp housing, thereby minimizing the volume caused by wiring.

[0055] Figure 7 A schematic structural diagram of the second base 3 from another angle is given. Figure 8 The schematic diagram of the assembly structure of the wire installation structure is given. Figure 2 , Figure 4 , Figure 7 and Figure 8In some embodiments, the first rotating part 121 is a columnar structure, and a protruding first stopper 1211 is provided on the side wall of the first rotating part 121, and a protruding second stopper 32 is provided on the second slot 31. When the wire 1 rotates relative to the second slot 31 through the wire support 12, the second stopper 32 is used to block the first stopper 1211 to prevent the wire 1 from rotating beyond an angle and causing entanglement and other problems.

[0056] Furthermore, the side wall of the second slot body 31 may be recessed to form a rotation groove 311 on one side close to the input end of the wire 1. When the first rotating portion 121 is connected to the second slot body 31, the first limit block 1211 is inserted into the rotation groove 311, and the first limit block 1211 can rotate along the rotation groove 311. The second limit block 32 is arranged at the side wall of the rotation groove 311. Since the rotation groove 311 is formed by the recess of the side wall of the second slot body 31, the first limit block 1211 is inserted into the rotation groove 311 and is also restricted by the upper groove wall of the rotation groove 311, and can abut against the upper groove wall of the rotation groove 311, thereby preventing the first rotating portion 121 from detaching from the second base 3, and increasing the stability of the structure.

[0057] For further reference, Figure 3 , Figure 4 and Figure 7 , the second base 3 may also be provided with a positioning groove 312, which is connected to the second slot body 31. Correspondingly, the first base 2 is provided with a protruding positioning block 221 at the side plate 22. Among them, the positioning block 221 is relatively located above the rotating groove 311 to avoid reducing the rotatable angle of the wire due to affecting the rotation trajectory of the first limit block 1211. In addition, the positions of the positioning block 221 and the second limit block 32 are relatively staggered, and the positioning block 221 is preferably located opposite to the second limit block 32. During the installation of the wire installation structure 10, the first limit block 1211 is aligned with the positioning groove 312, the wire input part 13 passes through the second through hole 34 of the second base 3, and the first rotating part 121 is connected to the second through hole 34. At this time, it is necessary to rotate the wire bracket 12 relative to the second base 3, so that the first limit block 1211 rotates along the rotating groove 311 and away from the positioning groove 312, to avoid the first limit block 1211 being located below the positioning groove 312. Next, the wire input portion 13 is passed through the first through hole 212 of the first base 2, the positioning groove 312 is aligned with the positioning block 221, and the second base 3 and the wire 1 connected to the second base 3 are brought close to the first base 2, so that the second base 3 is embedded and installed in the first base 2, and the installation of the first base 2, the second base 3 and the wire 1 is completed. The positioning groove 312 and the positioning block 221 realize the positioning of the installation between the first base 2 and the second base 3, and the positioning groove 312 and the positioning block 221 can also prevent the first limit block 1211 from detaching from the positioning groove 312 after being buckled with the positioning block 221.

[0058] In some embodiments, reference Figure 2 and Figure 3 The first rotating part 121 is provided with a third stopper 1212 on the side close to the wire input part 13, that is, on the bottom surface of the end connected with the wire input part 13. The first base 2 is provided with a groove 211, and the third stopper 1212 is inserted into the groove 211, thereby fixing the rotation position of the wire support 12 relative to the second base 3. The third stopper 1212 can be arranged below the first stopper 1211.

[0059] Furthermore, the third limit block 1212 may be a columnar protrusion or a spherical protrusion. A plurality of grooves 211 may surround a limit area with an arc-shaped structure. During the rotation of the first rotating part 121, the third limit block 1212 slides along the limit area. Specifically, a plurality of grooves 211 may be arranged along the circumference of the first slot body 23 to surround a limit area that is approximately circular.

[0060] In some embodiments, see Figure 2 and Figure 4 The wire support 12 further includes a second rotating portion 122, which is disposed above the first rotating portion 121 and fixedly connected to the wire body 11. The wire 1 body passes through the second rotating portion 122 and the first rotating portion 121 in sequence and then bends. The end of the second rotating portion 122 away from the extension direction of the wire body 11 is sealed, which protects the bend of the wire 1 body.

[0061] Furthermore, the second rotating part 122 is further provided with a rotating surface 1213, and the second base 3 is provided with a supporting surface 33. After the wire support 12 is connected to the second base 3, the first rotating part 121 is connected to the first slot 23, and the rotating surface 1213 of the second rotating part 122 is closely connected with the supporting surface 33 of the second base 3. When the wire 1 rotates, the rotating surface 1213 is closely connected with the supporting surface 33 and rotates relatively, that is, the wire support 12 is closely connected with the first base 2, which is conducive to the fitting of the lamp housing and further avoids the wire 1 from protruding relative to the lamp housing.

[0062] The wire installation structure provided in this embodiment realizes the rotational installation of the wire through the cooperation between the wire bracket, the first base and the second base, which facilitates the connection of the wire with the power line at different angles, meets the requirements of different wiring positions, and is convenient for users to use. At the same time, the bending structure between the wire body and the wire input part allows the wire body to be as close to the outside of the installation base as possible, so it is suitable for use on devices that need to be installed in a small space.

[0063] Embodiment 2:

[0064] This embodiment provides a lamp 100 based on the above-mentioned embodiment 1. The lamp 100 includes a lamp housing 20, a light source assembly 30, an optical component 40, a fastener 50, and a wire mounting structure 10.

A mounting cavity is formed in the face frame 201 and the back frame 202. The light source assembly 30 and the optical component 40 are mounted in the mounting cavity. The wire mounting structure 10 is fixed on the mounting plane 203 of the lamp housing 20.

[0066] The first base 2 has first through holes 212 on both sides of the first slot 23, and the second base 3 has second through holes 34 on both sides of the second slot 31. The fastener 50 passes through the second through holes 34 and the first through holes 212 in sequence and is fixedly connected to the mounting plane 203.

[0067] Furthermore, the wire input portion 13 can be electrically connected to the light source assembly 30 after passing through the first base 2, the second base 3 and the lamp housing 20. The first rotating portion 121 of the wire support 12 has a first central axis L1. After the wire 1 is installed on the installation plane 203, the wire body 11 rotates relative to the installation plane 203 with the first central axis L1 as the rotation axis. In this embodiment, the angle between the wire body 11 and the wire input portion 13 is 90°, so that the wire body 11 is parallel to and close to the installation plane 203, so that the wire does not protrude relative to the lamp 100, which is conducive to the installation of the lamp 100 in a narrow space.

[0068] It should be noted that, in addition to the direct-down LED lamp, the lamp 100 may also be a downlight or other types of lamps 100 , and this is not intended to be the only limitation on the type of the lamp 100 .

The fastener 50 passes through the second through holes 34 and the first through holes 212 in sequence and is fixedly connected to the mounting plane 203, thereby connecting the wire mounting structure 10 to the mounting plane 203. This is conducive to realizing that the lamp 100 meets different wiring position requirements and is suitable for installation in a narrow space.

[0073] The downlight provided in this embodiment is connected to an external power line through a wire installation structure, wherein the wire can rotate relative to the lamp housing, reducing the need for external power line routing positions, so that the lamp can meet different wiring positions, and avoid the need to increase power wiring or adjust the lamp installation position as much as possible.
