Description

Technical Field

[0001] This utility model belongs to the field of LED flat panel light technology, and in particular relates to a direct-lit LED flat panel light. Background Technology

[0002] LED panel lights are lighting fixtures that are energy-saving, high-brightness, mercury-free, infrared-free, ultraviolet-free, electromagnetic interference-free, heat-free, radiation-free, and flicker-free. They are generally used in hotels, conference rooms, factories or offices, commercial applications, residential or public facilities, schools, hospitals, and other places requiring energy-saving and high color rendering index lighting. Depending on the customer's requirements, the installation of panel lights can be matched with emergency functions, providing continuous power for up to 3 hours after a power outage. LED panel lights use LCD backlight technology and high-efficiency LED chips, along with a unique heat dissipation design, ensuring high LED efficiency, low light decay, and long lifespan.

[0003] Most existing direct-lit LED panel lights are typically fixed to their mounting positions using bolts. This requires workers to install or remove multiple bolts during installation and removal, making the process cumbersome and reducing efficiency. Therefore, this paper proposes a new type of direct-lit LED panel light. Utility Model Content

[0004] The purpose of this utility model is to provide a direct-lit LED panel light, which solves the problem that existing direct-lit LED panel lights require workers to install or remove multiple bolts during use, making the installation and disassembly of direct-lit LED panel lights cumbersome and reducing the efficiency of installation or disassembly.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a direct-lit LED flat panel light, comprising a mounting top plate, a mounting box fixedly connected to the lower surface of the mounting top plate, a flat panel light assembly installed inside the mounting box, movable grooves formed on both inner walls of the mounting box, support plates slidably connected inside the movable grooves, snap-fit ​​mechanisms installed on the surfaces of the two support plates, mounting rods threadedly connected to both edges on one side of the support plates, insertion grooves formed on the surfaces of the mounting rods, two corresponding elastic blocks fixedly connected symmetrically inside the insertion grooves, limit rods fixedly connected to one end of each of the two elastic blocks, the two limit rods corresponding to the insertion grooves, and sliding grooves formed on both edges of the mounting box.

[0007] Furthermore, both sides of the sliding groove are provided with through grooves that communicate with the mounting box. The through grooves correspond to the limiting rods. Both sides of the mounting box surface are fixedly connected with heat dissipation rods in a path array.

[0008] Furthermore, the flat panel light assembly includes a retaining plate fixedly connected to the top wall of the mounting box. The lower surface of the retaining plate is fixedly connected with elastic discs in a rectangular array. The surfaces of the four elastic discs are together attached to the flat panel light holder. The two sides of the lower surface of the flat panel light holder are respectively attached to the corresponding support plates.

[0009] Furthermore, the limiting rod corresponds to the sliding groove, the mounting rod is slidably connected inside the sliding groove, and the four corners of the mounting top plate are all threaded with fixing bolts.

[0010] Furthermore, the locking mechanism includes four sliding blocks that are respectively fixedly connected to the upper and lower surfaces of the support plate. All four sliding blocks are slidably connected inside the movable groove, and the sliding blocks correspond to the movable groove.

[0011] Furthermore, the locking mechanism also includes four locking slots respectively opened on both sides of the bottom wall and the top wall of the movable groove, and the four sliding blocks are slidably connected to the inside of the corresponding locking slots. A reset spring is fixedly connected inside the locking slot, and the reset spring is fixedly connected to the corresponding sliding block.

[0012] Furthermore, the flat panel light assembly also includes a flat panel light housing fixedly connected to the lower surface of the flat panel light holder. The interior of the flat panel light housing has a rectangular array of corresponding flat panel light bodies fixedly connected thereto, and the heat dissipation rods are respectively attached to both sides of the flat panel light holder.

[0013] This utility model has the following beneficial effects:

[0014] By incorporating a mounting box, movable slot, support plate, elastic block, limiting rod, and snap-fit ​​mechanism, the two support plates are pushed into the movable slot, thus removing their restraint on the flat panel light holder and allowing the light holder to be inserted into the mounting box. A reset spring then moves the support plate to the lower surface of the light holder, restraining it. The cooperation of the mounting rod and limiting rod further restricts the support plate, preventing it from detaching from the movable slot. Finally, the clamping plate and elastic disc secure the flat panel light assembly. The system uses a snap-fit ​​mechanism to install the panel light assembly. When disassembly is required, the two support plates are pushed to detach them from the panel light assembly, allowing for easy disassembly of the direct-lit LED panel light. This simplifies the installation and disassembly of direct-lit LED panels and improves the efficiency of installation and disassembly. It also solves the problem in existing technologies where multiple bolts need to be installed or removed, which makes the installation and disassembly of direct-lit LED panel lights cumbersome and reduces their efficiency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1-5As shown, this utility model is a direct-lit LED flat panel light, including a mounting top plate 1. Each of the four corners of the mounting top plate 1 is threaded with fixing bolts 2. A mounting box 3 is fixedly connected to the lower surface of the mounting top plate 1. Heat dissipation rods 12 are fixedly connected to both sides of the surface of the mounting box 3 in a path array. A flat panel light assembly is installed inside the mounting box 3. The flat panel light assembly includes a clamping plate 13 fixedly connected to the inner top wall of the mounting box 3. Elastic discs 14 are fixedly connected to the lower surface of the clamping plate 13 in a rectangular array. Through the clamping plate 13 and the elastic discs 14, the elastic discs 14 press against the flat panel light holder 15, thereby installing the direct-lit LED flat panel light through the elastic discs 14 and the support plate 5. Then, the mounting top plate 1 is installed in the corresponding installation position using the fixing bolts 2, completing the installation of the direct-lit LED flat panel light. The surfaces of the four elastic discs 14 are in contact with the flat panel light holder 15, pushing two... The support plate 5 slides inside the movable groove 4, so that the support plate 5 no longer limits the inside of the mounting box 3, allowing the flat panel lamp holder 15 to be inserted into the inside of the mounting box 3. The flat panel lamp assembly also includes a flat panel lamp housing 16 fixedly connected to the lower surface of the flat panel lamp holder 15. The interior of the flat panel lamp housing 16 has a rectangular array of fixedly connected several corresponding flat panel lamp bodies 17. Several heat dissipation rods 12 are respectively attached to both sides of the flat panel lamp holder 15. Movable grooves 4 are provided on both inner walls of the mounting box 3. The support plate 5 is slidably connected inside the movable groove 4. The two sides of the lower surface of the flat panel lamp holder 15 are respectively attached to the corresponding support plate 5. The surfaces of the two support plates 5 are each equipped with a snap-fit ​​mechanism. The snap-fit ​​mechanism includes four sliding blocks 18 fixedly connected to both sides of the upper and lower surfaces of the support plate 5. The four sliding blocks 18 are slidably connected inside the movable groove 4, and the sliding blocks 18 correspond to the movable groove 4.

[0027] The locking mechanism also includes four locking grooves 19 respectively opened on both sides of the bottom and top walls of the movable groove 4. Four sliding blocks 18 are slidably connected to the interior of the corresponding locking grooves 19. A reset spring 20 is fixedly connected inside the locking groove 19. Through the elastic force of the reset spring 20, the sliding block 18 slides inside the locking groove 19, thereby driving the support plate 5 to slide synchronously inside the movable groove 4, so that the support plate 5 is in contact with the lower surface of the flat panel lamp holder 15, limiting the position of the flat panel lamp holder 15. The reset spring 20 is fixedly connected to the corresponding sliding block 18. The two edges on one side of the support plate 5 are threaded with mounting rods 6. The surface of the mounting rod 6 is provided with insertion grooves 7. The interior of the insertion grooves 7 is symmetrically fixed with two corresponding elastic blocks 8. One end of each elastic block 8 is fixedly connected with a limit rod 9. The two limit rods 9 are corresponding to the insertion grooves 7. Sliding grooves 10 are provided on both sides of the mounting box 3. With the elastic block 8 in place, when the support plate 5 moves, it simultaneously drives the mounting rod 6 to move, causing the limiting rod 9 to move to the outside of the sliding groove 10. The elastic force of the elastic block 8 then causes the limiting rod 9 to engage with both sides of the sliding groove 10, limiting the support plate 5 and preventing it from detaching from the movable groove 4, which would otherwise prevent the support plate 5 from limiting the flat panel light holder 15. The limiting rod 9 corresponds to the sliding groove 10, and the mounting rod 6 is slidably connected inside the sliding groove 10. Both sides of the sliding groove 10 have through grooves 11 that communicate with the mounting box 3. These through grooves 11 correspond to the limiting rod 9. When the direct-lit LED flat panel light needs to be disassembled, the limiting rod 9 pulls the mounting rod 6 to slide inside the sliding groove 10, thereby causing the support plate 5 to slide inside the movable groove 4, disengaging the support plate 5 from the flat panel light holder 15, and thus detaching the flat panel light assembly from the mounting box 3, completing the disassembly of the flat panel light assembly.

[0028] Specifically, in use, this direct-lit LED flat panel light works as follows: The two support plates 5 slide within the movable groove 4, thus removing the support plates 5 from their position within the mounting box 3. This allows the flat panel light holder 15 to be inserted into the mounting box 3. The spring force of the reset spring 20 causes the sliding block 18 to slide within the snap-fit ​​groove 19, which in turn causes the support plates 5 to slide synchronously within the movable groove 4. This brings the support plates 5 into contact with the lower surface of the flat panel light holder 15, thus limiting its position. Furthermore, due to the elastic block 8, when the support plates 5 move, the mounting rod 6 moves synchronously, thus limiting its position. The positioning rod 9 moves to the outside of the sliding groove 10, so that the elastic force of the elastic block 8 makes the positioning rod 9 engage with both sides of the sliding groove 10, limiting the support plate 5. This avoids the problem that the support plate 5 cannot limit the lamp holder 15 because it is separated from the movable groove 4. At the same time, the setting of the clamping plate 13 and the elastic plate 14 makes the elastic plate 14 squeeze the lamp holder 15, so that the direct-lit LED flat panel light is installed through the elastic plate 14 and the support plate 5. Then, the mounting top plate 1 is installed in the corresponding installation position by fixing bolts 2, thus completing the installation of the direct-lit LED flat panel light.

[0029] When it is necessary to disassemble the direct-lit LED panel light, the mounting rod 6 is moved by the limiting rod 9 to slide inside the sliding groove 10, thereby causing the support plate 5 to slide inside the movable groove 4, so that the support plate 5 is separated from the panel light holder 15, thereby separating the panel light assembly from the mounting box 3, completing the disassembly of the panel light assembly, which facilitates the disassembly of the LED panel light by the staff and improves the disassembly efficiency of the direct-lit LED panel light.
