Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to a luminaire. Background Technology

[0002] Currently, there are some shortcomings in the replacement and installation process of optical components (such as lenses and light-transmitting plates) in the light source cavity of traditional high-bay lighting fixtures, especially in terms of dustproof and insect-proof design, optical component fixing, and structural cost.

[0003] Traditional designs typically rely on deforming the side of the light-transmitting panel to forcibly remove the lens, or use screws to fix the lens. While this structure can secure the lens, it has several drawbacks. First, replacing the light-transmitting panel by deforming its side is prone to damage and fails to effectively prevent dust and insects from entering the lamp, thus failing to meet dust and insect prevention requirements. Second, fixing the lens with screws is cumbersome, requiring screw removal for lens replacement, which is inconvenient and time-consuming. This design cannot achieve a stable, screwless lens fixation structure, resulting in inconvenient and potentially unstable lens mounting.

[0004] Currently, existing technologies employ a spring-and-hinge hinged structure for the side cover to facilitate opening. While this design enables the side cover to open, its high manufacturing cost directly increases the overall production cost of the luminaire. Furthermore, this complex side cover opening structure makes disassembling and replacing optical components more cumbersome, increasing the difficulty of maintenance and use.

[0005] Therefore, existing technologies have significant shortcomings in terms of dust and insect prevention, ease of optical component replacement, and structural cost, and a new solution is urgently needed to improve the overall performance of luminaires. Utility Model Content

[0006] In order to reduce the manufacturing cost of high-bay lighting fixtures, improve the convenience of optical component replacement, and meet the requirements of dust and insect prevention, this application provides a lighting fixture.

[0007] The lighting fixture provided in this application adopts the following technical solution:

[0008] A lamp fixture includes a lamp body heat sink, a light-transmitting plate, and a side cover; the lamp body heat sink has a receiving groove, the light-transmitting plate is installed in the receiving groove, and the side cover is rotatably mounted on the lamp body heat sink by a rotating component; by flipping the side cover, the side cover can be moved along the moving direction of the light-transmitting plate, thereby sealing the opening of the receiving groove, and the side cover is fixed to the lamp body heat sink by a snap-fit ​​limiting component.

[0009] By adopting the above technical solution, this application avoids the reliance on complex screw and spring structures in traditional designs through the design of rotating parts and snap-fit ​​limiting parts, simplifying the structure and assembly process of the lamp and effectively reducing manufacturing costs. The rotating and snap-fit ​​fixing design of the side cover makes the replacement of optical components simpler and faster. Operators do not need to disassemble multiple parts; they can easily replace the light-transmitting plate simply by flipping or opening the side cover, improving maintenance efficiency. At the same time, the sealing design of the snap-fit ​​fixing of the side cover can effectively seal the opening of the receiving slot, preventing external dust and insects from entering the lamp, improving the lamp's dustproof and insectproof performance, and ensuring the long-term stable operation of the optical components. This application not only effectively solves the problems in traditional designs but also makes the product more competitive in the market by simplifying the structure and reducing production costs, while improving the user experience.

[0010] In one specific implementation, the lamp body heat sink is provided with a sliding groove, which is connected to the opening of the receiving groove; by flipping the side cover, the side cover can be inserted into the sliding groove and moved along the sliding groove so that the side cover seals the opening of the receiving groove.

[0011] By adopting the above technical solution and through the design of the sliding groove, the side cover can move smoothly and accurately seal the opening of the receiving groove, simplifying the installation steps. The sealing can be completed simply by sliding the side cover, reducing the difficulty and time of operation during the assembly process. Furthermore, due to the sliding design of the side cover, maintenance personnel can quickly slide the side cover to replace the light-transmitting plate. Compared with the traditional screw fixing design, it provides a simpler operation method and reduces maintenance time.

[0012] In one specific implementation, the rotating component includes a rotating shaft disposed on the side cover, the lamp body heat sink is provided with a rotating groove, the rotating groove is disposed on both sides of the slide groove and communicates with the slide groove, the rotating shaft is slidably and rotatably disposed in the rotating groove, and the rotating shaft is fixed in the rotating groove by a pressure cap and screws.

[0013] By adopting the above technical solution, the design of the rotating shaft and rotating groove allows the rotating shaft to slide and rotate smoothly within the rotating groove, providing better flexibility for adjusting the side cover. When installing the light-transmitting plate, the user can easily adjust the position of the side cover to ensure that it can be correctly aligned with the slot of the lamp body heat sink. This design simplifies the traditional installation method, making the installation of the rotating shaft and side cover more convenient and avoiding cumbersome fixing steps. Furthermore, the design of fixing the rotating shaft in the rotating groove with a pressure cap and screws ensures that the rotating shaft will not loosen during use, thereby improving the stability of the device.

[0014] In one specific implementation, the slide groove is provided with a guide limiting structure, and the side cover is provided with a slide bar. The guide limiting structure is used to guide and limit the movement of the slide bar, thereby guiding the movement of the side cover.

[0015] By adopting the above technical solution, the design of the guide and limiting structure during the sliding process of the side cover can ensure that the side cover always slides along the correct path, thereby ensuring the accurate docking of the subsequent limiting ribs and grooves and improving the assembly accuracy.

[0016] In one specific implementation, the guide limiting structure includes two guide protrusions, a guide groove is formed between the two guide protrusions, the slider corresponds to the guide groove, the slider can be inserted into the guide groove and move within the guide groove.

[0017] By adopting the above technical solution, the guide protrusion and guide groove are used to achieve accurate positioning of the slide bar, so that the side cover can move strictly along the predetermined track during the sliding process, avoiding the side cover from deviating or sliding irregularly, thereby ensuring accurate docking between the limiting rib and the groove, and improving the overall assembly accuracy and stability.

[0018] In one specific implementation, the guide protrusion is discontinuous in the middle.

[0019] By adopting the above technical solution and utilizing the break in the middle of the guide protrusion, the contact area of ​​the slider in the guide groove can be reduced, friction and sliding resistance can be reduced, and the slider can move more smoothly in the guide groove, thereby improving sliding performance and enhancing the smoothness and flexibility of movement.

[0020] In one specific implementation, the width of the slider gradually increases from the end initially inserted into the guide groove to the far end.

[0021] By adopting the above technical solution, the gradually widening design can prevent the slider from getting stuck during movement; as the width of the slider gradually increases, it can better adapt to possible assembly tolerances, avoid jamming caused by assembly deviations or deformation, and improve the reliability of the system.

[0022] In one specific implementation, the width of the far end of the slider is equal to the width of the guide groove.

[0023] By adopting the above technical solution, this design ensures that the width of the slider end is equal to the width of the guide groove, and that the front end of the slider is smaller than the width of the guide groove when moving, effectively avoiding jamming problems and ensuring that the slider can move smoothly and stably. When the width of the slider end is equal to the width of the guide groove, the slider and the guide groove can be tightly connected, ensuring stable contact between the slider and the guide groove after the side cover is fixed.

[0024] In one specific implementation, the snap-fit ​​limiting member includes a groove formed on the lamp body heat sink and a limiting rib provided on the side cover. The groove communicates with the opening of the receiving groove, and the limiting rib is inserted into the groove and is interference-fitted with the groove.

[0025] By adopting the above technical solution, the interference fit between the limiting rib and the groove can provide a stable connection, making the connection between the side cover and the lamp body heat sink less prone to loosening, greatly enhancing the stability and tensile strength of the connection, and avoiding loosening caused by vibration or external force.

[0026] In one specific implementation, the side cover is provided with a disassembly port for inserting a tool to pry open the side cover.

[0027] By adopting the above technical solution, when the lamp needs to be cleaned, replaced or maintained, users or maintenance personnel can easily insert tools into the disassembly port and pry open the side cover, thus providing a simple way to disassemble the side cover and reducing the complexity of the disassembly process.

[0028] In summary, the beneficial technical effects of this application are as follows: This lamp design simplifies the assembly and maintenance process by using innovative structures such as rotating parts, snap-fit ​​limiting parts, and sliding grooves, avoiding the reliance on complex screw and spring structures in traditional designs; the flip-and-slide design of the side cover not only reduces manufacturing costs but also improves the efficiency of light-transmitting panel replacement, allowing maintenance personnel to quickly and easily replace the light-transmitting panel without disassembling multiple parts; at the same time, the sealing design of the side cover effectively prevents dust and insects from entering the lamp, ensuring long-term stable operation of the lamp.

[0029] In addition, the sliding design of the side cover, combined with the guide and limiting structure, ensures the accuracy and smoothness of installation and operation; the cooperation of the slider and guide groove reduces jamming and improves the overall assembly accuracy; through this series of optimizations, this design not only enhances the user experience of the lamp, but also strengthens the lamp's dustproof and insect-proof capabilities, making the product more competitive in the market.

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] Reference Figure 1 and Figure 2 This application discloses a lamp, including a lamp body heat sink 1, a light-transmitting plate 2, and a side cover 3. In this embodiment, the lamp body heat sink 1 is horizontally arranged, and there are two light-transmitting plates 2 and two side covers 3. The side covers 3 are arranged correspondingly to the light-transmitting plates 2, and the light-transmitting plates 2 are placed horizontally.

[0039] The lamp body heat sink 1 is provided with two receiving slots 11, which are correspondingly arranged with the light-transmitting plate 2. The opening of the receiving slot 11 is located on the side of the lamp body heat sink 1. The light-transmitting plate 2 enters through the opening of the receiving slot 11 and moves horizontally into the receiving slot 11 and is installed in the receiving slot 11. The side cover 3 is rotatably mounted on the lamp body heat sink 1 by the rotating part 4, and the side cover 3 can move along the moving direction of the light-transmitting plate 2, thereby blocking the opening of the receiving slot 11. The side cover 3 is fixed to the lamp body heat sink 1 by the snap-fit ​​limiting part 5.

[0040] Before installation, the side cover 3 is mounted on the lamp body heat sink 1 via the rotating part 4. The rotating part 4 allows the side cover 3 to be flipped on the lamp body heat sink 1 for easy subsequent operation. When assembling the light-transmitting plate 2, first push the light-transmitting plate 2 into the receiving groove 11 from the opening of the receiving groove 11 and into the receiving groove 11 inside the lamp body heat sink 1. Ensure that the light-transmitting plate 2 is accurately aligned with the inner wall of the receiving groove 11. After completion, flip the side cover 3 to the appropriate position and push the side cover 3 to move along the moving direction of the light-transmitting plate 2. At this time, the side cover 3 will move smoothly and block the opening of the receiving groove 11. After the side cover 3 completely blocks the opening, the snap-locking limit part 5 tightly fixes the side cover 3 to the lamp body heat sink 1, ensuring that the internal light-transmitting plate 2 is effectively sealed, thereby preventing dust and insects from entering the lamp and keeping the lamp clean and the optical components stable.

[0041] In this embodiment, the side cover 3 includes an integral movable plate 31 and a cover plate 32. The movable plate 31 and the cover plate 32 are arranged vertically. When the side cover 3 is flipped to the movable position, the movable plate 31 is arranged horizontally and the cover plate 32 is arranged vertically. The upper surface of the lamp body heat sink 1 is provided with a sliding groove 12. The sliding groove 12 is arranged horizontally and is connected to the slot of the receiving groove 11. By flipping the side cover 3, the movable plate 31 of the side cover 3 can be inserted into the sliding groove 12 and move horizontally along the sliding groove 12 so that the cover plate 32 of the side cover 3 seals the slot of the receiving groove 11. Through the design of the sliding groove 12, the side cover 3 can move smoothly and accurately seal the slot of the receiving groove 11, simplifying the installation steps. Only the side cover 3 needs to be slid to complete the sealing, reducing the operation difficulty and time in the assembly process.

[0042] Reference Figure 3 and Figure 4 The slide groove 12 is provided with two sets of guide limiting structures 6, and the side cover 3 is provided with two slide bars 33. The guide limiting structures 6 are correspondingly set with the slide bars 33. The guide limiting structure 6 includes two guide protrusions 61, which are set along the moving direction of the slide bars 33. That is, in this embodiment, the guide protrusions 61 are set along the width direction of the slide groove 12. A guide groove 62 is formed between the two guide protrusions 61. The slide bars 33 correspond to the guide groove 62. By flipping the side cover 3, the slide bars 33 can be inserted into the guide groove 62 and move within the guide groove 62. Through the design of the slide groove 12, the side cover 3 can move smoothly and accurately seal the opening of the receiving groove 11, simplifying the installation steps. Only the side cover 3 needs to be slid to complete the sealing, reducing the operation difficulty and time in the assembly process. Furthermore, due to the sliding design of the side cover 3, maintenance personnel can quickly slide the side cover 3 to replace the light-transmitting plate 2. Compared with the traditional screw 43 fixing design, it provides a simpler operation method and reduces maintenance time.

[0043] The guide protrusion 61 is broken in the middle, forming a gap (as shown in the attached image). Figure 4 (As shown by the dotted line in the diagram). This design can reduce the contact area of ​​the slider 33 in the guide groove 62, reduce friction and sliding resistance, and make the slider 33 move more smoothly in the guide groove 62, thereby improving sliding performance and enhancing the smoothness and flexibility of movement.

[0044] Reference Figure 4 and Figure 5 In this embodiment, for better illustration in the accompanying drawings, the end of the slider 33 that initially enters the guide groove 62 is designated as end A, which is located near the rotating member 4. The end of the slider 33 that ultimately enters the guide groove 62 is designated as end B, which is located near the snap-fit ​​limiting member 5. The width of the slider 33 gradually increases from end A to end B (see attached drawing). Figure 5The gradually widening design can prevent the slider 33 from getting stuck during movement; as the width of the slider 33 gradually increases, it can better adapt to possible assembly tolerances, avoid jamming caused by assembly deviations or deformation, and improve the reliability of the system.

[0045] The width of the very end of the slider 33 is equal to the width of the guide groove 62, that is, the width of end B of the slider 33 is equal to the width of the guide groove 62. This design ensures that the width of the end of the slider 33 is equal to the width of the guide groove 62, and that the front end of the slider 33 is smaller than the width of the guide groove 62 when moving, effectively avoiding jamming problems and ensuring that the slider 33 can move smoothly and stably. At the same time, after the side cover 3 is fixed, the widest part of the slider 33 and the guide groove 62 can be tightly connected, improving the contact stability between the slider 33 and the guide groove 62.

[0046] Reference Figure 2 and Figure 5 The rotating component 4 includes a rotating shaft 41 disposed on the movable plate 31 of the side cover 3. The upper surface of the lamp body heat sink 1 is provided with a rotating groove 13. The rotating groove 13 is disposed on both sides of the slide groove 12 and is connected to the slide groove 12. The rotating shaft 41 is slidably and rotatably disposed in the rotating groove 13. The rotating shaft 41 is fixed in the rotating groove 13 by a pressure cap 42 and a screw 43. In this embodiment, the lamp body heat sink 1 is provided with a screw hole 14. During installation, the rotating component is placed in the rotating groove 13, and the pressure cap 42 is used to press and fix the rotating shaft 41 in the rotating groove 13. Then, the screw 43 passes through the pressure cap 42 and is threadedly connected to the screw hole 14 of the lamp body heat sink 1 to fix the rotating shaft 41.

[0047] Reference Figure 3 In this embodiment, the side cover 3 can be rotated 140° around the pivot from a horizontal position. When the light-transmitting plate 2 needs to be assembled, the side cover 3 is rotated 140° around the pivot so that the opening of the receiving groove 11 is fully opened. At this time, the side cover 3 abuts against the upper surface of the lamp body heat sink 1. After the light-transmitting plate 2 is assembled, the side cover 3 is rotated 140° to a horizontal position. The movable plate 31 of the side cover 3 is inserted into the slide groove 12 with the rotation action, and the slide bar 33 is inserted into the guide groove 62 with the rotation action. At this time, the movable plate 31 of the side cover 3 is set horizontally, and the cover plate 32 is set vertically. The side cover 3 can be pushed, and the movable plate 31 of the side cover 3 moves along the slide groove 12 so that the cover plate 32 of the side cover 3 blocks the opening of the receiving groove 11.

[0048] Reference Figure 2 , Figure 4 , Figure 6The snap-fit ​​limiting component 5 includes a groove 52 formed on the lamp body heat sink 1 and a limiting rib 51 provided on the side cover 3. In this embodiment, the limiting rib 51 is provided on the cover plate 32 of the side cover 3. The cover plate 32 is provided on both sides of the limiting rib 51. The groove 52 is correspondingly provided with the limiting rib 51, and the groove 52 is connected to the slot of the receiving groove 11. By pushing the side cover 3, the limiting rib 51 is inserted into the groove 52, and the limiting rib 51 and the groove 52 are interference fit.

[0049] When the side cover 3 is pushed to move, the cover plate 32 of the side cover 3 will align with and seal the opening of the receiving groove 11, and the limiting rib 51 will align with the groove 52. When the side cover 3 reaches the opening, the limiting rib 51 is inserted into the groove 52. Once the limiting rib 51 is fully inserted into the groove 52, the limiting rib 51 will form an interference fit with the groove 52, and the side cover 3 and the lamp body heat sink 1 will be firmly connected together, completing the snap-fit ​​fixation. Through the interference fit between the limiting rib 51 and the groove 52, a stable connection can be provided, making it difficult for the connection between the side cover 3 and the lamp body heat sink 1 to loosen, greatly enhancing the stability and tensile strength of the connection, and avoiding the problem of loosening caused by vibration or external force.

[0050] Reference Figure 2 and Figure 6 The side cover 3 is provided with a disassembly port 7 for inserting tools to pry open the side cover 3. In this embodiment, the disassembly port 7 is a long and narrow rectangular opening. The disassembly port 7 is located on the movable plate 31 of the side cover 3, and the disassembly port 7 is located on the side of the movable plate 31 away from the cover plate 32. When the side cover 3 is sealed in the groove of the receiving groove 11, the disassembly port 7 abuts against the inner wall of the sliding groove 12.

[0051] The disassembly port 7 allows for easy disassembly of the side cover 3. When the lamp needs cleaning, replacement, or maintenance of other components such as the light-transmitting plate 2, the user or maintenance personnel can easily insert tools (such as flathead screwdrivers, pry bars, etc.) into the disassembly port 7 and pry open the side cover 3 using the lever principle, thus providing a simple way to disassemble the side cover 3 and reducing the complexity of the disassembly process.

[0052] The implementation principle of this application embodiment is as follows: When it is necessary to assemble the light-transmitting plate 2, the side cover 3 is rotated 140° around the pivot, so that the groove of the receiving groove 11 is fully opened. At this time, the side cover 3 abuts against the upper surface of the lamp body heat sink 1; then the light-transmitting plate 2 is pushed in from the groove of the receiving groove 11 and enters the receiving groove 11 in the lamp body heat sink 1, ensuring accurate docking between the light-transmitting plate 2 and the inner wall of the receiving groove 11.

[0053] After the light-transmitting plate 2 is assembled, the side cover 3 is rotated 140° around the pivot to a horizontal position. The movable plate 31 of the side cover 3 is inserted into the slide groove 12 as it is rotated, and the slide bar 33 is inserted into the guide groove 62 as it is rotated. At this time, the movable plate 31 of the side cover 3 is horizontal and the cover plate 32 is vertical, so the side cover 3 can be pushed to move towards the receiving groove 11. Pushing the side cover 3, the movable plate 31 moves along the slide groove 12, and the slide bar 33 moves along the guide groove 62. At this time, the slide bar 33 and the guide groove 62 can guide the side cover 3 to move along the expected movement trajectory, so that the cover plate 32 of the side cover 3 is aligned with the opening of the receiving groove 11, and the limiting rib 51 is aligned with the groove 52.

[0054] When the side cover 3 reaches the opening of the receiving groove 11, the limiting rib 51 is inserted into the groove 52. Once the limiting rib 51 is fully inserted into the groove 52, the limiting rib 51 will form an interference fit with the groove 52, and the side cover 3 and the lamp body heat sink 1 will be firmly connected together. At this time, the side cover 3 completely seals the opening of the receiving groove 11, and the assembly of the side cover 3 and the lamp body heat sink 1 is completed.

[0055] When it is necessary to replace the light-transmitting plate 2, insert a flathead screwdriver into the disassembly port 7, press down the flathead screwdriver, and pry open the side cover 3 by lever principle. Separate the limiting rib 51 from the groove 52, disconnect the side cover 3 from the lamp body heat sink 1, and complete the disassembly of the side cover 3. Then, the light-transmitting plate 2 can be pulled out through the slot of the receiving groove 11, and the new light-transmitting plate 2 can be assembled by the aforementioned assembly method.

[0056] The lamp design provided in this application significantly simplifies the installation and disassembly process of the light-transmitting plate 2 through the innovative structure of the flip-up side cover 3 and the sliding groove 12. In this design, the side cover 3, through the design of the pivot 41, can be flipped to open the receiving groove 11 for the installation of the light-transmitting plate 2. After assembly, the side cover 3 can also be flipped to reach a suitable position so that the side cover 3 can be moved to seal the receiving groove 11. The movable plate 31 of the side cover 3 moves horizontally along the sliding groove 12 through the guide groove 62 and the slide bar 33 to accurately seal the opening of the receiving groove 11. The limiting rib 51 of the side cover 3 achieves a stable connection by interference fit with the groove 52 on the lamp body heat sink 1. This design not only improves the sealing performance of the lamp and effectively prevents dust and insects from entering the lamp, but also ensures the stability and cleanliness of the light-transmitting plate 2 and extends the service life of the lamp.

[0057] Furthermore, the sliding design of the side cover 3 makes the replacement of the light-transmitting plate 2 easier. The disassembly port 7 provides a convenient tool access point for users or maintenance personnel, allowing the side cover 3 to be easily disassembled when the light-transmitting plate 2 needs to be replaced, thereby reducing maintenance time and operational complexity. Compared with the traditional screw 43 fixing method, this sliding and flipping structure greatly improves maintenance efficiency and enhances the reliability and stability of the lamp. At the same time, this design can effectively adapt to assembly tolerances, reduce possible jamming problems, and improve the smoothness and flexibility of the overall system.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
