Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular, to a lighting insulation installation structure and a lighting fixture. Background Technology

[0002] Existing lighting fixture installations only use ordinary plastic expansion screws and ordinary self-tapping screws for fixing, with the fixture base directly attached to the wall without any insulation distance. Some solutions use separate insulating pads, which are prone to being lost, misaligned, or falling off during installation, making the installation process cumbersome. At the same time, ordinary metal self-tapping screws are in direct contact with the metal fixture base, and leakage current inside the fixture can easily be conducted along the screws to the entire base, causing the base casing to become electrified, posing a significant electrical safety hazard. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a lamp insulation installation structure and lamp that can directly increase the insulation effect between the chassis and the wall and is easy to install.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lamp insulation mounting structure, including a lamp base, and multiple sets of plastic expansion screws and self-tapping screws; the lamp base has multiple mounting holes, the plastic expansion screws are used for mounting on the ceiling or wall and correspond to the positions of the mounting holes, and the self-tapping screws pass through the mounting holes and cooperate with the plastic expansion screws; an integrally formed insulating spacer is provided on the outer side of the top of the plastic expansion screw, and the top dimension of the insulating spacer facing the lamp base is larger than the diameter of the mounting hole.

[0005] Furthermore, the insulating spacer has a frustum-shaped structure, with the bottom dimension being larger than the top dimension.

[0006] Furthermore, the lamp base is provided with multiple recesses, and the multiple mounting holes are distributed one-to-one in the multiple recesses.

[0007] Furthermore, the self-tapping screw is provided with a plastic insulating layer on the outside.

[0008] Furthermore, the plastic insulating layer is located at the top of the self-tapping screw and extends downward, and the length of the downward-extending plastic insulating layer is greater than the depth of the mounting hole.

[0009] A lamp includes a lampshade, a driver board, a light source module, and an insulating mounting structure for the lamp; the lampshade is fastened to the top inner edge of the lamp base from above, and the driver board and the light source module are electrically connected and both are mounted on the top of the lamp base.

[0010] Furthermore, the lampshade and lamp base are rectangular structures, and the number of plastic expansion screws and self-tapping screws is six sets, with three sets of plastic expansion screws and self-tapping screws distributed on each of the two long sides of the lamp base.

[0011] Furthermore, the bottom edge of the lampshade is provided with a bent portion that engages with the top inner edge of the lamp base. The edge of the lamp base is provided with multiple rotating buckles that penetrate the lamp base. The multiple rotating buckles are used to engage the bent portion to connect the lampshade and the lamp base.

[0012] Furthermore, the rotating buckle includes a wrench part, a buckle part, and a fastening screw. The wrench part has a rotating shaft in the vertical direction, the buckle part has a rotating cylinder sleeved on the rotating shaft, and the fastening screw locks the rotating cylinder and the rotating shaft sequentially from the top.

[0013] Furthermore, anti-rotation grooves are provided on both symmetrical sides of the top of the rotating shaft, and anti-rotation blocks that engage with the anti-rotation grooves are provided on both symmetrical sides inside the rotating cylinder.

[0014] Beneficial effects: This utility model effectively separates the lamp base from the mounting surface by setting an integrally molded insulating spacer on the top of the plastic expansion screw. At the same time, the top size of the insulating spacer is larger than the diameter of the mounting hole, so it can hold against the outside of the mounting hole without passing through it. Structurally, it achieves full insulation and isolation, effectively preventing leakage current from being conducted to the lamp base, improving the safety of lamp installation and use. Moreover, the integral structure requires no additional accessories, making installation simpler and more efficient.

[0015] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0031] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0035] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, a lamp insulation mounting structure includes a lamp base 100, multiple sets of plastic expansion screws 110 and self-tapping screws 120. The lamp base 100 has multiple mounting holes 101. The plastic expansion screws 110 are pre-installed on the ceiling or wall, with their positions corresponding one-to-one with the mounting holes 101. The self-tapping screws 120 pass through the mounting holes 101 and engage with the plastic expansion screws 110 through thread, thereby fixing the lamp in place.

[0036] Combination Figure 1 , Figure 2 , Figure 3 As shown, in this embodiment, an insulating spacer 111 is integrally formed on the outer top of the plastic expansion screw 110. The height of the insulating spacer 111 is at least 10mm to ensure that the creepage distance is greater than 10mm. The top dimension of the insulating spacer 111 facing the lamp base 100 is larger than the diameter of the mounting hole 101, so that it can hold against the outer side of the mounting hole 101 and prevent it from passing through the mounting hole 101. After assembly, the insulating spacer 111 completely separates the lamp base 100 from the plastic expansion screw 110 and the mounting surface, preventing direct contact between metal parts and achieving insulation isolation.

[0037] Combination Figure 2 , Figure 3 As shown, in this embodiment, the insulating spacer 111 is configured as a frustum-shaped structure with a bottom dimension larger than the top dimension, which facilitates assembly and positioning while ensuring stable support and reliable insulation. The lamp base 100 has multiple downward-protruding recesses 102, with mounting holes 101 correspondingly located inside the recesses 102. The downward protrusion of the recesses 102 further increases the creepage distance, allowing the heads of the self-tapping screws 120 to be hidden within the recesses 102, improving the flatness of the appearance and insulation safety.

[0038] Combination Figure 3As shown, in this embodiment, the self-tapping screw 120 is provided with a plastic insulating layer 121 on the outside. The thickness of the plastic insulating layer 121 is greater than or equal to 2mm to ensure the insulation effect. The plastic insulating layer 121 is located on the top of the self-tapping screw 120 and extends downward. The extension length is greater than the depth of the mounting hole 101, so that the self-tapping screw 120 does not contact the lamp base 100 at all, further enhancing the insulation effect.

[0039] Combination Figure 1 , Figure 5 , Figure 6 As shown, in this embodiment, a lamp includes a lampshade 200, a driver board 300, a light source module 400, and an insulating mounting structure for the lamp. The lampshade 200 is fastened to the top inner edge of the lamp base 100 from above, and the driver board 300 is electrically connected to and fixedly mounted on the top of the lamp base 100, forming a complete lighting fixture.

[0040] Combination Figure 5 , Figure 6 As shown, in this embodiment, both the lampshade 200 and the lamp base 100 are rectangular structures. A total of six sets of plastic expansion screws 110 and self-tapping screws 120 are provided, with three sets evenly distributed on each of the two long sides of the lamp base 100 to ensure uniform installation force and secure and reliable fixing.

[0041] Combination Figure 6 , Figure 7 , Figure 8 As shown, in this embodiment, the bottom edge of the lampshade 200 is provided with a bent portion 201, which is engaged with the top inner edge of the lamp base 100; a plurality of through-hole rotating buckles 500 are installed on the edge of the lamp base 100, which engage with the bent portion 201 to realize quick assembly and disassembly of the lampshade 200 and the lamp base 100.

[0042] Combination Figure 7 , Figure 8 As shown, in this embodiment, the rotary buckle 500 includes a wrench portion 510, a buckle portion 520, and a fastening screw 530. The wrench portion 510 has a rotating shaft 511 in a vertical direction, and the buckle portion 520 has a rotating cylinder 521. The rotating cylinder 521 is sleeved on the rotating shaft 511, and the fastening screw 530 locks the rotating cylinder 521 and the rotating shaft 511 sequentially from the top, realizing the stable assembly of the rotary buckle 500. The rotating shaft 511 has anti-rotation grooves 512 on both symmetrical sides at the top, and the rotating cylinder 521 has anti-rotation blocks on both symmetrical sides inside. The anti-rotation blocks are engaged in the anti-rotation grooves 512 to prevent loosening and slippage during use, ensuring stable and reliable fastening.

[0043] In this embodiment, during installation, the plastic expansion screws 110 are first fixed to the ceiling or wall. Then, the mounting holes 101 of the lamp base 100 are aligned with the plastic expansion screws 110, so that the insulating spacer 111 is supported on the bottom of the lamp base 100. Subsequently, the self-tapping screws 120 with plastic insulation layer 121 are passed through the mounting holes 101 and tightened to complete the insulation installation. After the lampshade 200 is fastened inside the lamp base 100, the wrench part 510 of the rotating buckle 500 can be rotated from the outside, which simultaneously drives the buckle part 520 to rotate and lock onto the bending part 201 of the lampshade 200, realizing the quick disassembly and assembly connection between the lampshade 200 and the lamp base 100. The overall installation is convenient, and the entire process is insulated and isolated, effectively preventing leakage current from being conducted to the lamp base, making it safer to use.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
