Description

Technical Field

[0001] This utility model relates to the field of ceiling light technology, and in particular to a modular structure for ceiling lights that is easy to maintain. Background Technology

[0002] Modular ceiling light structure refers to the independent disassembly of the core functional components of a ceiling light through standardized mechanical connections, forming individually detachable modular units. This allows for the replacement or maintenance of only the corresponding module when a single component malfunctions, without the need to disassemble the entire light fixture. This structure aims to simplify maintenance processes and reduce operational difficulty, and is especially suitable for ceiling lights installed high on the ceiling. By optimizing the connection, positioning, and fixing methods between modules, users or maintenance personnel can quickly replace components, reducing maintenance time and costs, while also improving the product's lifespan and reusability.

[0003] Early ceiling lights featured a one-piece structure, with the light source, power supply, and lampshade directly fixed to the light frame via welding and screws. There was a lack of independent space for disassembly between these components. This structure presented significant drawbacks for maintenance. If the light source failed, the entire light fixture had to be removed from the ceiling for replacement. If the driver power supply failed, the lampshade or the outer casing of the light fixture had to be damaged to access the power supply components, which was not only cumbersome but also risked damaging other intact parts during disassembly. To address these issues, modern ceiling lights have gradually adopted a modular design. This allows for quick separation of the lampshade from the light body using snap-fit, magnetic, or rail structures. The driver power supply is integrated into a separate compartment and connected to the light source via a plug-in interface. While individual modules can be disassembled and replaced without the need for complex tools, ceiling lights typically have ventilation holes on the sides or back to ensure heat dissipation inside the lamp body. Existing ventilation holes are mostly simple grille or hollow designs. Although they can allow air circulation to prevent the light source and power supply from being damaged by overheating, they cannot stop phototactic insects. These insects will enter the lampshade through the ventilation holes, and because the internal structure of the lampshade is closed and lacks escape channels, the insects will eventually die and accumulate inside the lampshade, forming a blocking layer over time. This causes the light emitted by the light source to be absorbed or scattered, significantly reducing the brightness of the ceiling light. Cleaning these insect remains requires disassembling the lampshade, increasing the maintenance frequency and operational complexity. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a modular structure for easy-to-maintain ceiling lights, aiming to improve the problem in the prior art where insects can enter the lampshade through ventilation holes, die and accumulate inside the lampshade due to the closed internal structure, thereby reducing the lighting brightness.

The top of each L-shaped connecting pipe is connected to a hollow block. The inner wall of the hollow block is rotatably connected to an inclined partition plate. The bottom end of the outer wall of each L-shaped connecting pipe penetrates the top of the top plate and is fixedly connected to multiple arc-shaped guide plates. The bottom ends of the multiple arc-shaped guide plates are fixedly connected to baffles.

[0008] The fixing mechanism includes multiple hollow cones, the outer walls of which are respectively arranged around the inner wall of the top plate. A hollow hexagonal block is fixedly connected to the bottom end of each hollow cone. A cross-grooved rotating block is rotatably connected to the inner wall of each hollow hexagonal block. A lead screw is fixedly connected to the top end of each cross-grooved rotating block. A grooved ring is threadedly connected to the outer wall of the lead screw. Multiple support bars are rotatably connected to the inner wall of the grooved ring. Multiple extrusion bars are rotatably connected to the inner wall of each hollow cone. The top end of each support bar is rotatably connected to the inner wall of its corresponding support bar.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes multiple magnetic blocks, the bottom ends of which are fixedly connected to the top of the lamp panel. U-shaped blocks are fixedly connected to all four sides of the top of the lamp panel, and L-shaped plates are fixedly connected to all four sides of the bottom of the top panel.

[0011] As a further description of the above technical solution:

LED lights are used for illumination, and the L-shaped connecting pipe serves as a ventilation channel. External airflow is intercepted by the inclined partition plate above the hollow block and then enters the L-shaped connecting pipe and the ceiling light. Under the diversion of the arc-shaped guide plate, it blows to the surroundings to dissipate heat. The heat flows out through the hollow block, pushing the inclined partition plate to rotate, which increases the gap of the hollow block, thus preventing external insects from entering the ceiling light and improving ventilation and heat dissipation efficiency.

[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] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a modular structure for easy-to-maintain ceiling light, including a top plate 1, a lamp plate 4, and a frosted lampshade 7. The top of the top plate 1 is provided with an intercepting mechanism 2, and the top of the inner wall of the top plate 1 is provided with multiple fixing mechanisms 3. Multiple LED lights 5 are fixedly connected to the bottom of the lamp plate 4. The illumination of the LED lights 5 penetrates the frosted lampshade 7 to complete the illumination. The top of the lamp plate 4 is provided with a limiting component 6, and the lamp plate 4 is connected to the top plate 1 through the limiting component 6. The top of the frosted lampshade 7 is provided with a snap-fit ​​component 8, and the ceiling light uses the snap-fit ​​component 8 to connect the frosted lampshade 7 to the top plate 1.

[0034] The interception mechanism 2 includes multiple L-shaped connecting pipes 201. The outer walls of the multiple L-shaped connecting pipes 201 are respectively fixedly connected to the top of the top of the top plate 1. The top of the L-shaped connecting pipe 201 is connected to a hollow block 202. The inner wall of the hollow block 202 is rotatably connected to an inclined partition plate 203. The bottom of the outer wall of the L-shaped connecting pipe 201 penetrates the top of the top plate 1 and is fixedly connected to multiple arc-shaped guide plates 204. The airflow from the outside enters the L-shaped connecting pipe 201 and enters the ceiling light after being intercepted by the inclined partition plate 203 above the hollow block 202. Under the diversion of the arc-shaped guide plates 204, the airflow blows to all sides, which makes heat dissipation better. The bottom of the multiple arc-shaped guide plates 204 is fixedly connected to a baffle plate 205.

[0035] Specifically, the ceiling light uses a snap-fit ​​assembly 8 to connect the frosted lampshade 7 to the top plate 1, and the lamp panel 4 is connected to the top plate 1 through a limiting assembly 6. The illumination of the LED light 5 penetrates the frosted lampshade 7 to complete the illumination. The L-shaped connecting pipe 201 serves as a ventilation channel. External airflow is intercepted by the inclined partition plate 203 above the hollow block 202 and enters the L-shaped connecting pipe 201 and then into the ceiling light. Under the diversion of the arc-shaped guide plate 204, the airflow blows in all directions, which facilitates better heat dissipation. When the heat inside the lampshade is greater than that outside, the heat flows out through the hollow block 202, which in turn pushes the inclined partition plate 203 to rotate, increasing the gap in the hollow block 202 and accelerating the airflow. This prevents insects from entering the ceiling light and improves the ventilation and heat dissipation efficiency.

[0036] Reference Figure 3 , Figure 4 and Figure 6The fixing mechanism 3 includes multiple hollow cones 301. The outer walls of the multiple hollow cones 301 are respectively arranged around the inner wall of the top plate 1. The bottom end of the hollow cone 301 is fixedly connected to a hollow hexagonal block 302. Rotating the hollow hexagonal block 302 causes the hollow cone 301 to drill into the ceiling or roof under the action of rotation, thereby installing the top plate 1 above the ceiling or roof. The inner wall of the hollow hexagonal block 302 is rotatably connected to a cross-grooved rotating block 303. The top end of the cross-grooved rotating block 303 is fixedly connected to a lead screw 304. The outer wall of the lead screw 304 is threadedly connected to a grooved ring 305. The inner wall of the grooved ring 305 is rotatably connected to multiple The inner wall of the hollow cone 301 is rotatably connected to the support bar 306 and the support bar 306. The top of the support bar 306 is rotatably connected to the inner wall of the corresponding support bar 306. The cross groove block 303 is rotated using a cross tool, which causes the lead screw 304 to rotate together. Under the action of the threaded connection, the outer groove ring 305 moves accordingly, which then pushes the support bar 306 to rotate. This pushes the support bar 306 to rotate, which in turn pushes the support bar 307 that is engaged in the inner side of the hollow cone 301 to rotate outward. This causes the support bar 307 to rotate and press against the inner wall of the drilled hole, thus making the entire hollow cone 301 firmly engaged in the drilled hole.

[0037] Specifically, when installing the top plate 1, the hollow hexagonal block 302 is rotated sequentially, causing the hollow cone 301 to drill into the ceiling or roof under the action of rotation, thereby installing the top plate 1 on the ceiling or roof. Then, the cross-shaped tool is used to rotate the cross groove block 303, causing the lead screw 304 to rotate as well. Under the action of the threaded connection, the outer groove ring 305 moves accordingly, and then pushes the support bar 306 to rotate, thereby pushing the extrusion bar 307, which is engaged inside the hollow cone 301, to rotate outward. This causes the extrusion bar 307 to rotate and press against the inner wall of the drilled hole, thereby making the entire hollow cone 301 firmly engaged in the drilled hole, preventing it from loosening and falling off.

[0038] Reference Figure 1 , Figure 3 and Figure 5The limiting component 6 includes multiple magnetic blocks 601, the bottom ends of which are fixedly connected to the top of the lamp plate 4. The magnetic blocks 601 on the top of the lamp plate 4 and the corresponding positions on the bottom of the top plate 1 are attracted to each other, thus initially achieving pre-fixation and position calibration of the lamp plate 4. U-shaped blocks 602 are fixedly connected to all four sides of the top of the lamp plate 4, and L-shaped plates 603 are fixedly connected to all four sides of the bottom of the top plate 1. The U-shaped blocks 602 on the top of the lamp plate 4 and the L-shaped plates 603 on the bottom of the top plate 1 are interlocked, with the L-shaped plates 603 inserted into the grooves of the U-shaped blocks 602, thus limiting the horizontal displacement of the lamp plate 4. To prevent the lamp panel 4 from falling off when the magnetic block 601 loses its magnetism, the locking assembly 8 includes multiple L-shaped locking blocks 801. The bottom ends of the multiple L-shaped locking blocks 801 are rotatably connected to the top periphery of the frosted lampshade 7. The top of the L-shaped locking blocks 801 is rotatably connected to a tension spring 802. The other end of the tension spring 802 is rotatably connected to the top of the top plate 1. Rotating the L-shaped locking blocks 801 around the top periphery of the frosted lampshade 7 causes them to lock into the corresponding slots on the top plate 1. At this time, the tension spring 802 is in a stretched state, and its rebound force is used to tighten the L-shaped locking blocks 801 to ensure a firm lock and prevent the lampshade from loosening.

[0039] Specifically, in the limiting component 6, the magnetic block 601 on the top of the lamp panel 4 and the corresponding position on the bottom of the top plate 1 are attracted to each other, initially achieving pre-fixation and position calibration of the lamp panel 4. At the same time, the U-shaped blocks 602 around the top of the lamp panel 4 and the L-shaped plates 603 on the bottom of the top plate 1 are interlocked. The L-shaped plates 603 are inserted into the grooves of the U-shaped blocks 602, limiting the displacement of the lamp panel 4 in the horizontal direction and preventing the lamp panel 4 from falling off when the magnetic blocks 601 lose their magnetism. In the locking component 8, a frosted surface is used. The lampshade 7 and the top plate 1 can be quickly disassembled and assembled. When installing the lampshade, rotate the L-shaped locking blocks 801 around the top of the frosted lampshade 7 so that it can be locked into the corresponding slots on the top plate 1. At this time, the tension spring 802 is in a stretched state. Use its rebound force to tighten the L-shaped locking blocks 801 to ensure a firm engagement and prevent the lampshade from loosening. When cleaning or maintenance is required, pull the L-shaped locking blocks 801 outward to disengage them from the slots. The tension spring 802 will be further stretched. After releasing, the lampshade can be removed. The operation is convenient and requires no tools.

[0040] Reference Figure 1 , Figure 3 and Figure 5The inner wall of the frosted lampshade 7 engages with the bottom of the outer wall of the top plate 1, which can play a preliminary positioning role for the frosted lampshade 7, ensuring that the frosted lampshade 7 can be quickly aligned with the top plate 1 during installation. The inner wall of the L-shaped locking block 801 engages with the outer wall of the top plate 1, which can firmly fix the frosted lampshade 7 on the top plate 1. The outer wall size of the inclined partition plate 203 is the same as the outer size of the inner wall of the hollow block 202, so that the inclined partition plate 203 can fit tightly against the inner wall of the hollow block 202. This prevents insects from easily entering due to excessive gaps, while also ensuring that the inclined partition plate 203 can rotate flexibly. The inner wall of the lamp plate 4 engages with the middle of the bottom of the top plate 1, which limits the position of the lamp plate 4. The inner wall of the U-shaped block 602 engages with the outer wall of the corresponding L-shaped plate 603. The groove of the U-shaped block 602 can accommodate the L-shaped plate 603. Through the engagement of the two, the lamp plate 4 is limited in the horizontal direction. The bottom end of the top plate 1 is magnetically attracted to the magnetic block 601. By using the magnetic force, the top plate 1 and the lamp plate 4 can be pre-fixed quickly. The top of the lamp plate 4 is provided with multiple ventilation holes 10. The ventilation holes 10 can provide a good heat dissipation channel for the LED lights 5 on the lamp plate 4. Multiple silicone limiting cylinders 9 are fixedly connected to the top center of the top of the top plate 1. They can limit the connection between the top plate 1 and the mounting surface from all sides and reduce the shaking of the top plate 1 during installation and use.

[0041] Specifically, the inner wall of the frosted lampshade 7 engages with the bottom end of the outer wall of the top plate 1, providing initial positioning for the frosted lampshade 7 and ensuring that it can be quickly aligned with the top plate 1 during installation. Simultaneously, it provides support from the inside to prevent shaking or shifting during use. The inner wall of the L-shaped locking block 801 engages with the outer wall of the top plate 1, firmly fixing the frosted lampshade 7 to the top plate 1. The close contact between the L-shaped locking block 801 and the outer wall of the top plate 1 enhances the stability of the connection, preventing the frosted lampshade 7 from falling off due to gravity or external forces. The outer wall dimensions of the inclined partition plate 203... The size of the inclined partition plate 203 is consistent with the outer dimensions of the inner wall of the hollow block 202, allowing it to fit tightly against the inner wall of the hollow block 202. This prevents insects from easily entering due to excessive gaps while ensuring that the inclined partition plate 203 can rotate flexibly. This achieves ventilation and heat dissipation while effectively preventing external insects from entering the lamp body through the hollow block 202. The inner wall of the lamp plate 4 engages with the bottom center of the top plate 1, limiting the position of the lamp plate 4 and ensuring that it is precisely installed at the preset position at the bottom of the top plate 1. This ensures that the LED lights 5 on the lamp plate 4 are at the optimal lighting angle, while also enhancing the connection between the lamp plate 4 and the top plate. 1. The connection ensures overall integrity and reduces shaking during use. The inner wall of the U-shaped block 602 engages with the outer wall of the corresponding L-shaped plate 603. The groove of the U-shaped block 602 can accommodate the L-shaped plate 603. Through this engagement, the lamp plate 4 is horizontally limited, preventing horizontal displacement and further ensuring the stability and accuracy of the lamp plate 4 installation. The bottom end of the top plate 1 magnetically attracts the magnetic block 601. Utilizing magnetic force, the top plate 1 and the lamp plate 4 can be quickly pre-fixed, facilitating further reinforcement of the lamp plate 4 by the subsequent fixing mechanism 3. Simultaneously, when disassembling the lamp plate 4, only... The light panel 4 can be easily separated by overcoming magnetic force, simplifying the disassembly process. The top of the light panel 4 has multiple ventilation holes 10, which can provide a good heat dissipation channel for the LED lights 5 on the light panel 4, so that the heat generated by the LED lights 5 during operation can be dissipated in time, avoiding the impact of excessive temperature on the lifespan and lighting effect of the LED lights 5. Multiple silicone limiting cylinders 9 are fixedly connected to the top center of the top of the top plate 1, which can limit the connection between the top plate 1 and the mounting surface from all sides, reducing the shaking of the top plate 1 during installation and use, and preventing the top plate 1 from directly contacting the mounting surface and causing wear.

[0042] Working principle: First, the ceiling light connects the frosted lampshade 7 to the top plate 1 via the snap-fit ​​assembly 8. The lamp panel 4 is connected to the top plate 1 via the limiting assembly 6. The light is provided by LED lights 5, and the light penetrates the frosted lampshade 7 to complete the lighting function. The L-shaped connecting pipe 201 serves as a ventilation channel. The external airflow enters the L-shaped connecting pipe 201 under the interception of the inclined partition plate 203 above the hollow block 202, and then enters the interior of the ceiling light. Under the diversion effect of the arc-shaped guide plate 204, the airflow diffuses to all sides to achieve more effective heat dissipation. When the heat inside the lampshade is higher than that outside, the heat flows out through the hollow block 202, pushing the inclined partition plate 203 to rotate, increasing the gap of the hollow block 202 and accelerating the airflow speed. This not only prevents external insects from entering the ceiling light, but also improves the ventilation and heat dissipation efficiency.

[0043] Furthermore, through the fixing mechanism 3, when installing the top plate 1, the hollow hexagonal block 302 is rotated in sequence, so that the hollow cone 301 is drilled into the ceiling or roof under the action of rotation, thereby installing the top plate 1 above the ceiling or roof. Then, the cross-shaped tool is used to rotate the cross groove block 303, so that the lead screw 304 rotates together. With the help of the threaded connection, the outer groove ring 305 moves accordingly. Then, the support bar 306 is pushed to rotate, which in turn pushes the extrusion bar 307, which is engaged inside the hollow cone 301, to rotate outward, so that the extrusion bar 307 rotates and presses against the inner wall of the drilled hole, thereby making the entire hollow cone 301 firmly engaged in the drilled hole, preventing it from falling off due to loosening.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
