Description

Technical Field

[0001] This utility model relates to the field of LED flat panel light technology, specifically a waterproof and dustproof LED flat panel light. Background Technology

[0002] LED flat panel light is a high-end indoor lighting fixture. Its outer frame is made of aluminum alloy through anodizing, and the light source is LED. The entire fixture has a beautiful, simple, elegant and luxurious design. After the light passes through the high light transmittance light guide plate, it forms a uniform planar light emission effect. It has good illuminance uniformity, soft and comfortable light without losing brightness, and can effectively relieve eye fatigue.

[0003] A search of the China Patent Network revealed an existing patent (publication number: CN108613044A) that discloses a waterproof and dustproof LED flat panel light. By installing dustproof nets on the air inlet and outlet, it can prevent dust in the air from entering the frame and thus avoid affecting the operation of the equipment inside the frame. The top plate is composed of a water-absorbing plate and a water-blocking plate, which can absorb water and prevent water droplets from damaging the indoor environment, while also preventing water from entering the frame.

[0004] However, the above-mentioned technical solutions still have certain drawbacks. The dustproof net in the device is prone to accumulating dust after long-term use, which affects the ventilation effect and may lead to an increase in the internal temperature of the lamp, affecting the lifespan of the lamp. At the same time, in severely humid environments, it is necessary to clean the water inside the water absorption plate. However, the device lacks a convenient cleaning method and can only be cleaned by disassembling the entire structure, which makes the cleaning process cumbersome and inefficient, increasing maintenance costs and time. Therefore, a waterproof and dustproof LED flat panel light is proposed. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides a waterproof and dustproof LED flat panel light, which effectively solves the problem of dust accumulation on the dustproof mesh affecting ventilation, while simultaneously enhancing the waterproof effect inside the flat panel light.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waterproof and dustproof LED flat panel light, including a top plate, a frame fixed at the bottom of the top plate, a circuit board installed inside the frame, LED beads at the bottom of the circuit board, a waterproof component on the inner wall of the frame, and a disassembly component on one side of the frame.

[0007] The waterproof component includes reset springs located on both sides inside the frame. The upper end of the reset spring is fixed to the top plate, and a square extrusion plate is fixed to the bottom end of the reset spring. Multiple sets of flexible water-absorbing plates are evenly spaced along the perimeter of the bottom of the square extrusion plate. A support plate is provided at the bottom end of the multiple sets of flexible water-absorbing plates. L-shaped connecting plates are fixed on both sides of the support plate. A horizontal plate is fixed on the upper end of the L-shaped connecting plate near the frame. The horizontal plate is slidably connected to the frame. Pull blocks penetrating both sides of the frame are provided on both sides of the square extrusion plate.

[0008] As a preferred technical solution, the top of the circuit board is connected to a wire, and the top plate is provided with holes and slots for easy installation.

[0009] As a preferred technical solution, the frame is provided with a clearance groove for the flexible water-absorbing plate to move, and the bottom end of the support plate and the bottom end of the frame are on the same horizontal plane.

[0010] As a preferred technical solution, the flexible absorbent plate is fixed to the square extrusion plate and the support plate by Velcro.

[0011] As a preferred technical solution, the frame is provided with sliding grooves on both sides for the horizontal plate to slide.

[0012] As a preferred technical solution, the disassembly assembly includes a connecting frame installed on one side of the frame, a dustproof net is provided inside the connecting frame, two sets of grooves are provided on both sides of the frame near the connecting frame, a limiting spring is provided inside the groove, a horizontal axis is provided at the center of the limiting spring, and a locking block is provided at one end of the limiting spring to fix it to the horizontal axis. The connecting frame has locking slots on both sides that cooperate with the locking block.

[0013] In summary, the present invention has the following main advantages:

[0014] This invention utilizes a flexible water-absorbing plate to effectively absorb moisture from the dustproof mesh that enters the frame from humid air, preventing further moisture penetration into the frame and affecting the normal operation of the circuit board and LED chips. By pulling the pull block, the square extrusion plate squeezes the flexible water-absorbing plate, squeezing out the absorbed moisture, effectively extending the lifespan of the LED flat panel light and reducing the failure rate caused by humid environments.

[0015] This utility model allows the connecting frame and dustproof net to be removed from the frame by pulling the horizontal axes on both sides of the frame, so that the locking blocks can be completely disengaged from the slots on both sides of the connecting frame. At this time, the dustproof net can be cleaned by tapping or rinsing with clean water. After the dustproof net is cleaned, it can be reinstalled by simply aligning the connecting frame with the installation position on the frame. The entire disassembly and installation process does not require any tools, making it simple and convenient to operate and greatly improving the maintenance efficiency of the dustproof net.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A waterproof and dustproof LED flat panel light, such as Figure 1-5 As shown, it includes a top plate 100, a frame 110 fixed at the bottom of the top plate 100, a circuit board 120 installed inside the frame 110, an LED bead 130 at the bottom of the circuit board 120, a waterproof component 200 on the inner wall of the frame 110, and a disassembly component 300 on one side of the frame 110.

[0027] The waterproof component 200 includes a return spring 210 located on both sides inside the frame 110. The upper end of the return spring 210 is fixed to the top plate 100, and a square extrusion plate 220 is fixed to the bottom end of the return spring 210. Multiple sets of flexible water-absorbing plates 230 are evenly spaced along the perimeter of the bottom of the square extrusion plate 220. A support plate 240 is provided at the bottom end of the multiple sets of flexible water-absorbing plates 230. L-shaped connecting plates 250 are fixed on both sides of the support plate 240. A horizontal plate 251 is fixed on the side of the upper end of the L-shaped connecting plate 250 near the frame 110. The horizontal plate 251 is slidably connected to the frame 110. Pull blocks 260 penetrating both sides of the frame 110 are provided on both sides of the square extrusion plate 220.

[0028] The flexible absorbent plate 230 effectively absorbs moisture from the dustproof mesh 320 that enters the frame 110 from the humid air, preventing further moisture penetration into the frame 110 and affecting the normal operation of the circuit board 120 and the LED beads 130. When the flexible absorbent plate 230 absorbs too much moisture and needs to be removed, pulling down the pull block 260 causes the square extrusion plate 220 to move downwards. The square extrusion plate 220, through the flexible absorbent plate 230, causes the support plate 240 to move synchronously, causing the support plate 240 to move the L-shaped connecting plate 250 and the horizontal plate 251 within the moving groove 252. When the horizontal plate 251 slides down the moving groove 252... At the lower end, the support plate 240 moves the flexible water-absorbing plate 230 to below the frame 110, while limiting the support plate 240. At this time, the pull block 260 is pulled down continuously, which in turn drives the square extrusion plate 220 to extrude the water-absorbing plate 230, squeezing out the water absorbed by the flexible water-absorbing plate 230. After the water is squeezed out, the pull block 260 is released. Under the action of the return spring 210, the square extrusion plate 220 drives the flexible water-absorbing plate 230 and the support plate 240 back to their original positions inside the frame 110, continuing to perform the waterproof function, effectively extending the service life of the LED flat panel light and reducing the failure rate caused by the humid environment.

[0029] Please refer to this carefully. Figure 2 and Figure 3 The circuit board 120 is connected to the top of the wire 140. The top plate 100 is provided with a hole groove 101 for easy installation. The frame 110 is provided with a clearance groove 231 for the flexible water absorption plate 230 to move. The bottom of the support plate 240 is at the same level as the bottom of the frame 110.

[0030] The slot 101 allows users to easily install the entire LED flat panel light on the ceiling using bolts and other fasteners, ensuring the stability and convenience of the installation. The clearance slot 231 ensures that the flexible water absorption plate 230 can move smoothly up and down without being obstructed by the frame 110, thus affecting its normal function. The support plate 240 and the bottom of the frame 110 are kept at the same level, making the overall appearance of the light fixture neater and more beautiful.

[0031] Please refer to this carefully. Figure 3 and Figure 4 The flexible absorbent plate 230 is fixed to the square extrusion plate 220 and the support plate 240 by Velcro, and the frame 110 has moving grooves 252 on both sides for the horizontal plate 251 to slide.

[0032] The Velcro fastening method not only ensures a secure connection but also makes assembly and disassembly extremely convenient. When the flexible absorbent plate 230 needs to be replaced, it can be easily removed from the square extrusion plate 220 and support plate 240 by simply pulling it gently, and a new flexible absorbent plate 230 can be installed. The moving grooves 252 provided on both sides of the frame 110 provide a precise track for the sliding of the horizontal plate 251, ensuring the stability and smoothness of the square extrusion plate 220 during its up-and-down movement.

[0033] Please refer to this carefully. Figure 1 and Figure 5 The disassembly assembly 300 includes a connecting frame 310 installed on one side of the frame 110. The connecting frame 310 is provided with a dustproof net 320. The inside of the frame 110 is provided with two sets of grooves 331 on both sides near the connecting frame 310. The grooves 331 are provided with limiting springs 330. The center of the limiting spring 330 is provided with a horizontal axis 350, and one end of the limiting spring 330 is provided with a locking block 340 fixed to the horizontal axis 350. The connecting frame 310 is provided with slots 341 on both sides that cooperate with the locking block 340.

[0034] When cleaning or replacing the dust filter 320, simply pull the horizontal shafts 350 on both sides of the frame 110 simultaneously with your fingers. This will cause the horizontal shafts 350 to drive the locking blocks 340 to press against the limiting spring 330. Once the locking blocks 340 are completely disengaged from the slots 341 on both sides of the connecting frame 310, the connecting frame 310 along with the dust filter 320 can be removed from the frame 110. At this point, the dust filter 320 can be cleaned by tapping it to remove dust or rinsing it with water. After cleaning, reinstalling the dust filter 320 simply involves... Align the connecting frame 310 with the installation position on the frame 110 and gently push it inward. When the two sides of the connecting frame 310 contact the locking block 340, they will squeeze the locking block 340 and cause it to retract into the groove 331. When the groove 341 moves to the position corresponding to the locking block 340, the limit spring 330 will push the locking block 340 to reset and lock into the groove 341, thus completing the fixation of the dustproof net 320. The entire disassembly and installation process does not require any tools, and the operation is simple and convenient, greatly improving the maintenance efficiency of the dustproof net 320.
