Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a ceiling light. Background Technology

[0002] Currently, the structures of fire emergency lighting ceiling lights and conventional lighting ceiling lights on the market are relatively simple, as shown in the attached image. Figure 1 As shown, it typically consists of a lampshade 1, a lamp housing 2, a mounting base 3, and an internal lamp panel, assembled using conventional methods. However, in practical applications, existing ceiling lights have significant shortcomings:

[0003] (1) The way the lamp is fixed is relatively simple, either by internal clips or by screws, which increases the complexity of assembly and mold processing.

[0004] (2) Most lamps use integrated lampshades, resulting in low overall light output that fails to meet national standard luminous efficacy requirements;

[0005] (3) The mounting base is relatively small, and when installing the lamp, it is difficult to align the mounting base with the ceiling, making it impossible to achieve a high level of protection.

[0006] (4) The wiring harness requires a separate tail clip for fixation, which increases the cost.

[0007] In summary, existing ceiling lights have shortcomings in terms of fixing, light output, installation, and cost, and cannot meet user needs. There is an urgent need for ceiling lights with optimized structures to solve these problems. Utility Model Content

[0008] The purpose of this utility model is to provide a ceiling light to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a ceiling light, comprising a top panel, a lens, a back panel, and a lamp panel. The top panel includes a bottom plate and a side plate bent and fixed at the edge of the bottom plate. The lens is fixed to the bottom plate. Several positioning members are provided on the inner side wall of the bottom plate. The lamp panel abuts against the positioning members to fix the lamp panel horizontally. The back plate abuts against the back of the lamp panel to position the lamp panel vertically. The edge of the back plate is fixedly connected to the top panel. A hanging plate is detachably installed on the inner side of the top panel, and the top height of the hanging plate does not exceed the top of the side plate.

[0010] Furthermore, multiple lenses are provided, and each lens has a circumferentially bent rib at its edge. The inner side of the base plate is provided with a first positioning groove that matches the rib. The rib is inserted into the first positioning groove and fixed with adhesive.

[0011] Furthermore, the inner sidewall of the base plate is provided with a glue-applying groove, which is adapted to the edge contour of the back plate, and a number of elastic buckles for pressing the back plate onto the inner sidewall of the base plate are provided at the outer edge of the glue-applying groove.

[0012] Furthermore, the positioning component includes a first limiting plate vertically fixed to the back of the base plate, a second limiting plate fixed to the first limiting plate, and a support plate. The height of the support plate is less than the height of the first limiting plate. The lamp plate overlaps the support plate to support the lamp plate so that it is parallel to the base plate. The edge of the lamp plate is provided with a positioning hole that matches the second limiting plate. The first limiting plate abuts against the edge of the lamp plate for positioning.

[0013] Furthermore, it also includes a battery, and the inner side of the back plate is integrally formed with a cavity for accommodating the battery, the contour of which is adapted to the size of the battery.

[0014] Furthermore, the inner wall of the side plate is provided with a second positioning groove that matches the hanging plate. The end of the hanging plate near the side plate is bent and provided with a spring piece, and the contact surface between the spring piece and the side plate is provided with a snap-fit ​​part. The side plate is provided with a snap-fit ​​hole that matches the snap-fit ​​part.

[0015] Furthermore, cables are connected to the light panel, and the back panel side plate is provided with a cable routing port to accommodate the cables passing through.

[0016] Furthermore, the back plate and the bottom plate are provided with several slots near the cable, and the slots on the back plate and the bottom plate clamp the cable in the middle, and the slots are all arranged perpendicular to the cable routing direction.

[0017] Furthermore, the outer wall of the base plate is recessed inward to form a recessed portion, and the lens is located inside the recessed portion. The depth of the recessed portion is adapted to the thickness of the lens so that the lens does not protrude from the outer wall of the base plate.

[0018] Furthermore, the light panel is provided with a communication indicator light, and a thin-walled hole is opened in the recessed part corresponding to the position of the communication indicator light. The thin-walled hole is directly opposite the communication indicator light, and the thin-walled hole is made of transparent material or has a reserved light transmission channel to ensure that the indicator light signal can be clearly transmitted to the outside, so that the user can observe the status of the device.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) The lamp panel is positioned by the positioning parts on the inner side wall of the base plate and the back plate. It does not need to rely solely on buckles or screws. This avoids the high precision requirements of the mold and the problem of easy breakage of the buckle. It also eliminates the screw hole pre-setting and screwing process of screw fixing, reduces the difficulty of mold processing, shortens the assembly time, and improves the stability of lamp panel fixing, reducing the risk of loosening.

[0021] (2) The structure adopts several independent lenses and the recessed part of the base plate. The lenses can be made of high light transmittance material, and the recessed part can optimize the light propagation path. At the same time, the lenses are precisely fixed by the ring ribs and positioning grooves to avoid light blocking caused by assembly deviation, greatly reduce light loss, ensure that the light output rate of the whole lamp meets the national lighting efficiency standard, improve the lighting effect and save energy.

[0022] (3) The installation is assisted by the detachable mounting plate on the inner side of the upper panel. The mounting plate is quickly fixed with the help of the spring and snap-fit ​​structure. With the reasonable size design, the problem of the traditional small base is difficult to align is solved, and the installation difficulty is reduced. The back plate and the bottom plate are tightly connected by the glue groove and elastic buckle. The wiring port, the slot and other structures also take into account the sealing, which effectively improves the protection level of the whole lamp, reduces the impact of water vapor and dust on the internal components, and extends the service life.

[0023] (4) No additional tail clips are needed to fix the wire harness. The cable can be stably clamped by the slots on the back plate and the bottom plate, reducing material procurement costs. At the same time, the assembly structure of components such as lamp board, lens, and hanging plate is simplified, reducing assembly procedures and time, reducing production complexity, and making it more suitable for large-scale mass production needs, providing strong support for product cost control.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] Please see Figure 2-8 The present invention provides an embodiment of a ceiling light, comprising an upper panel 1, a lens 2, a back panel 3, and a lamp panel 4. In this embodiment, the upper panel 1 comprises a circular base plate 11 and an annular side plate 12 integrally bent and fixed at the edge of the base plate 11. The base plate 11 and the side plate 12 together enclose a cylindrical cavity with one end open. The inner sidewall mentioned below refers to the inner wall of the cylindrical cavity, which provides installation space for internal components.

[0035] Lens 2 is fixed on base plate 11. Specifically, there are three lenses 2, and the lamp panel 4 also has three rows of lamp beads corresponding to the three lenses 2. Figure 5 As shown, each of the three lenses 2 has a ring rib 21 integrally bent along its circumference at its edge. The base plate 11 has three mounting holes. The inner edge of the mounting hole has a first positioning groove 111 that matches the ring rib 21. The ring rib 21 is inserted into the first positioning groove 111 and then fixed by adhesive dispensing. This not only achieves a stable installation of the lens 2, but also achieves a waterproof and dustproof effect. At the same time, the design of the independent lens 2 can reduce light obstruction and effectively improve the light efficiency of the whole lamp.

[0036] The outer wall of the base plate 11 is recessed inward to form a recess 114. The lens 2 is located inside the recess 114. The depth of the recess 114 is matched with the thickness of the lens 2, so that the lens 2 does not protrude from the outer wall of the base plate 11. This ensures the flatness of the overall appearance of the ceiling light and provides some protection for the lens 2.

[0037] Several positioning elements 6 are provided on the inner wall of the base plate 11. The lamp plate 4 abuts against the positioning elements 6 to fix the lamp plate 4 horizontally. Figure 6-7 As shown, in this embodiment, four positioning members 6 are provided, symmetrically arranged on opposite sides of the lamp panel 4, as follows: Figure 8As shown, each positioning component 6 includes a first limiting plate 61 vertically fixed to the back of the base plate 11, a second limiting plate 62 vertically fixed to the first limiting plate 61, and a support plate 63. Two support plates 63 are provided, symmetrically arranged on both sides of the second limiting plate 62. The height of the support plate 63 is less than the height of the first limiting plate 61. During assembly, the four positioning holes 42 at the edge of the lamp panel 4 respectively engage with the second limiting plates 62 of the four positioning components 6. Simultaneously, the bottom surface of the lamp panel 4 overlaps the support plate 63, ensuring that the lamp panel 4 remains parallel to the base plate 11. The first limiting plate 61 abuts against the edge of the lamp panel 4, achieving bidirectional horizontal positioning. Subsequently, the back plate 3 is engaged with the top panel 1, pressing the back of the lamp panel 4 to complete the positioning of the lamp panel 4 in the height direction.

[0038] Compared to traditional fire-fighting ceiling lights that require separate buckles to fix the lamp panel 4, this embodiment eliminates the separate buckle design on the upper panel 1. The lamp panel 4 is pressed and fixed by the assembly of the back plate 3 and the upper panel 1, which reduces the difficulty of mold design, reduces the number of slider modules in mold design and processing, reduces the difficulty and cost of mold production and manufacturing, and reduces the cost of product manufacturing.

[0039] In this embodiment, the back plate 3 has a structure similar to the top panel 1, also including a bottom plate and a side plate integrally bent at the edge of the bottom plate. Several reinforcing ribs are provided on the inner side of the bottom plate. The side plate of the back plate 3 is fixedly connected to the top panel 1. Figure 5-7 As shown, a glue-applying groove 112 is provided on the inner sidewall of the base plate 11. The glue-applying groove 112 is adapted to the edge contour of the back plate 3, and several elastic buckles 113 are provided at the outer edge of the glue-applying groove 112 for pressing the back plate 3 onto the inner sidewall of the base plate 11. During assembly, the back plate 3 is inserted into the glue-applying groove 112 on the inner side of the side plate 12 along the height direction of the side plate 12. The multiple elastic buckles 113 will elastically abut against the back of the back plate 3 to achieve fixation, realizing quick fixation. The assembled product is as follows: Figure 3 As shown. This design supports flexible switching of protection levels: if a high waterproof level is required, sealant can be filled into the sealant application groove 112; if only basic protection is required, no sealant is needed, meeting the needs of different usage scenarios.

[0040] like Figure 4 As shown, a cable 41 is connected to the light panel 4 for power supply or signal transmission. A cable routing port 31 is provided on the side wall of the back plate 3 to facilitate the cable 41 to pass through. To prevent the cable 41 from becoming loose or worn, several slots 8 are provided on both the back plate 3 and the base plate 11 near the cable 41. The slots 8 on the back plate 3 and the base plate 11 clamp the cable 41 in the middle, and the slots 8 are all arranged perpendicular to the cable 41 routing direction. The wavy raised structure of the cross-section of the slot 8 can increase the contact area with the cable 41, which can play a role in fixing the wire harness and help the wire harness pass the tensile test. At the same time, the contact surface between the slot 8 and the cable 41 is an arc structure, which can reduce wear.

[0041] A communication indicator light is provided on the light panel 4 to display the device's operating status. A thin-walled hole 115 is provided in the recessed portion 114 of the base plate 11, corresponding to the position of the communication indicator light. The thin-walled hole 115 is directly opposite the communication indicator light and is made of transparent material or has a pre-reserved light-transmitting channel to ensure that the indicator light signal can be clearly transmitted to the outside, facilitating user observation of the device status. According to the national standard GB 17945-2024, the lamps need to pass an impact test. While typical lamps have holes at the communication indicator light location, this embodiment employs a thin-walled design and lowers the plane of the thin-walled area, preventing it from directly receiving impacts and thus preventing breakage due to collisions.

[0042] A mounting plate 5 is detachably installed on the inner side of the upper panel 1, such as... Figure 4 As shown, the mounting plate 5 is a long strip structure arranged radially along the upper panel 1, and its top height does not exceed the top of the side plate 12 to avoid installation interference. The specific assembly structure is as follows: the inner wall of the side plate 12 is provided with a second positioning groove 13 that matches the two ends of the length of the mounting plate 5, such as... Figure 5 As shown, when the hanging plate 5 is inserted into the second positioning groove 13, the bottom end of the hanging plate 5 is higher than the back plate 3, and its top end is flush with the side plate 12. Both ends of the hanging plate 5 are provided with bent spring pieces 51, which can be bent and deformed along the length of the hanging plate 5. Each spring piece 51 has a locking part 52 on its contact surface with the side plate 12. The side plate 12 has locking holes 121 that match the locking parts 52. The locking part 52 has a triangular cross-section, so that the width of the two ends of the hanging plate 5 near the spring pieces 51 gradually increases from top to bottom, which can serve as a guide during insertion. During insertion, the locking parts 52 at both ends of the hanging plate 5 are subjected to force and undergo elastic deformation towards the center of the hanging plate 5 until the locking part 52 enters the locking hole 121. The locking part 52 then returns to its original shape, achieving rapid fixing of the hanging plate 5 to the upper panel 1. Figure 3 As shown, the mounting plate 5 has multiple mounting holes along its length for easy assembly and fixing with the ceiling.

[0043] This ceiling light supports two power supply methods: a battery-free centralized power supply version and a battery-powered independent power supply version. This embodiment is the self-powered version, equipped with two batteries 7. The inner side of the back plate 3 has an integrally formed cavity to accommodate the batteries 7. The cavity outline is adapted to the size of the batteries 7. The cavity is specifically located on one side of the width of the mounting plate 5, which can make full use of the internal space and avoid occupying the installation area of ​​the core components.
