[0038] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0039] The following describes in detail, with reference to the accompanying drawings, the specific structure of a ceiling light provided by this utility model and the corresponding technical effects it brings.

[0040] It should be noted that the thickness in the embodiments of this application can be understood as the thickness of the ceiling light when it is upright, that is, the thickness direction can be understood as the thickness direction of the ceiling light itself when it is upright.

[0041] Please refer to Figures 1-4 The ceiling light 1 provided in this embodiment of the utility model includes a main frame 100, a light guide plate 200, a frame 300, a lampshade 500, and a base 400.

[0042] The main frame 100 includes a panel 110 and a surrounding panel 120. Both the panel 110 and the surrounding panel 120 are annular, and the surrounding panel 120 is disposed inside the panel 110. The panel 110 is provided with a receiving cavity 115, which is used to receive electrical connection wires and terminals. The terminals are electrically connected to the electrical connection wires. The light guide plate 200 is disposed on the panel 110 and covers the receiving cavity 115. That is, after the light guide plate 200 covers the receiving cavity 115, the terminals and electrical connection wires in the receiving cavity 115 are blocked, which can effectively prevent the electrical connection wires from being exposed and provide better insulation protection.

[0043] The electrical connection wire is used to electrically connect to the light-emitting component. It should be noted that, in this embodiment, the light-emitting component includes a main light-emitting element 630, a first light-emitting element 610, and a second light-emitting element 620.

[0044] The inner side of the panel 110 and the surrounding plate 120 together define the main light cavity 130. The aforementioned chassis 400 covers the panel 110 and is mounted on the panel 110 by threaded fasteners. Specifically, the chassis 400 covers the main light cavity 130. The lampshade 500 is connected to the surrounding plate 120 and is opposite to the chassis 400. The main frame 100, chassis 400, and lampshade 500 together define the main light mounting cavity. That is, the main light-emitting element 630 is installed in the main light mounting cavity. Specifically, in this embodiment, the main light-emitting element 630 is mounted on the chassis 400 so that the light emitted by the main light-emitting element 630 can be emitted through the lampshade 500. It should be noted that in this embodiment, the light guide plate 200 has a ring-shaped structure and is pressed on the chassis 400. The light guide plate 200 is fixed to the panel 110 by threaded fasteners to improve the stability of the connection between the chassis 400 and the panel 110.

[0045] It should be noted that in this embodiment, the panel 110 and the surrounding panel 120 are two parts on the integrated main frame 100. That is, the main frame 100 in this embodiment is an integrated structure. Of course, in some other embodiments, the panel 110 and the surrounding panel 120 may also be separate structures.

[0046] The frame 300 is located on the side of the panel 110 away from the light guide plate 200. The frame 300, the panel 110 and the light guide plate 200 are arranged sequentially along the thickness direction. The frame 300 is provided with a mating groove 320 and a first mounting cavity 310 arranged sequentially along the thickness direction and communicating with each other. The mating groove 320 is connected to the panel 110. The first mounting cavity 310 is used to install the first light-emitting element 610. The receiving cavity 115 is provided with a wire-passing hole 118 on the side near the frame 300, which communicates with the first mounting cavity 310. The electrical connection wire on the first light-emitting element 610 can enter the receiving cavity 115 through the wire-passing hole 118 and be electrically connected to the terminal.

[0047] It should be noted that, in order to facilitate the light output of the first light-emitting element 610, the frame 300 is also connected to a light guide 380, and the light guide 380 blocks the first mounting cavity 310.

[0048] Understandably, the electrical connection wires on the first light-emitting element 610 can enter the receiving cavity 115 through the wire hole 118 and be electrically connected to the terminal. The electrical connection wires of the first light-emitting element 610 can be wired within the receiving cavity 115, which can effectively prevent the electrical connection wires connected to the first light-emitting element 610 from being exposed, reduce the safety hazards caused by exposed electrical connection wires, and improve the overall aesthetics of the ceiling light 1.

[0049] In detail, the panel 110 is provided with a wire guide post 117, and the wire guide post 117 has a wire guide hole 118. The wire guide post 117 extends into the frame 300 and the wire guide hole 118 communicates with the first mounting cavity 310. It can be understood that the electrical connection wire on the first light-emitting element 610 can pass through the wire guide hole 118 of the wire guide post 117 and enter the receiving cavity 115 to protect the electrical connection wire from being easily cut by the hole in the frame 300.

[0050] The frame 300 is also provided with a mating groove 320. The mating groove 320 and the first mounting cavity 310 are arranged sequentially along the thickness direction, and the mating groove 320 is close to the panel 110. That is, the mating groove 320 is closer to the panel 110 than the first mounting cavity 310. The mating groove 320 has a through hole 323 that is positioned and mated with the wire guide post 117. The through hole 323 is connected to the first mounting cavity 317, and the wire guide post 117 is accommodated in the mating groove 320.

[0051] Understandably, the connection between the through hole 323 and the wire guide post 117 in this embodiment facilitates the assembly efficiency of the frame 300 and the panel 110. Furthermore, since the wire guide post 117 is accommodated within the mating groove 320, it effectively prevents light emitted by the light-emitting element in the first mounting cavity 310 from leaking through the wire guide hole 118.

[0052] Please refer to Figures 6-8 There are multiple wire guide posts 117 on the panel 110, and similarly, there are multiple via holes 323 on the frame 300. The multiple via holes 323 are configured one-to-one with the multiple wire guide posts 117. It should be noted that "multiple" in this embodiment can be understood as two or more, and the wire guide holes 118 of the wire guide posts 117 in this embodiment are connected to the receiving cavity 115.

[0053] Optionally, in some embodiments, the panel 110 is provided on the side away from the light guide plate 200 with a mating boss 116 that engages with the mating groove 320. The mating boss 116 engages with the mating groove 320 and is fixed by fasteners.

[0054] In detail, the mating groove 320 includes a first groove 321 and a second groove 322 arranged sequentially along the thickness direction, with the first groove 321 being closer to the panel 110 than the second groove 322. Both the first groove 321 and the second groove 322 are annular grooves, and the groove diameter of the first groove 321 is larger than that of the second groove 322. The second groove 322 is provided with an internal thread, and the mating boss 116 is accommodated in the first groove 321. The mating boss 116 is threadedly connected to the second groove 322 by a threaded fastener.

[0055] It should be noted that, in this embodiment, the second groove 322 is provided with the aforementioned through hole 323, and the diameter of the through hole 323 is smaller than the groove diameter of the first groove 321 and larger than the groove diameter of the second groove 322.

[0056] Understandably, when the frame 300 is assembled with the panel 110, the mating boss 116 on the panel 110 can be pre-assembled in the first groove 321. The mating boss 116 and the first groove 321 can achieve the pre-positioning of the panel 110 and the frame 300, and complete the insertion of the wire guide post 117 and the through hole 323 on the panel 110, thereby improving the installation efficiency of the panel 110 and the frame 300.

[0057] In detail, in this embodiment, there are multiple mating bosses 116, which are spaced apart around the panel 110 in the circumferential direction. That is, multiple mating bosses 116 are spaced apart around the surrounding plate 120 in the circumferential direction to improve the connection strength between the panel 110 and the frame 300.

[0058] In detail, the multiple mating bosses 116 are divided into two groups, and the extension directions of the mating bosses 116 in the two groups are set at an angle. In this embodiment, the frame 300 is approximately a quadrilateral frame 300, the inner hole of the panel 110 is a quadrilateral hole, and the surrounding plate 120 is approximately arranged in a hollow quadrangular prism shape.

[0059] Please refer to Figures 1-3 and Figure 5 The frame 300 is ring-shaped and is spaced apart from and surrounds the panel 120. The axis of the frame 300 is parallel to the axis of the panel 110, that is, the frame 300 and the panel 110 are misaligned. In a preset direction, the frame 300 has a misaligned portion 370 that protrudes from the panel 110. In other words, the part of the frame 300 located directly below the panel 110 is connected to the panel 110. The frame 300 is in a cantilever state and has the risk of collapsing. Therefore, in this embodiment, the ceiling light 1 also includes a connector 700. One end of the connector 700 is connected to the panel 110 and the other end is connected to the misaligned portion 370 to ensure the stability of the installation of the frame 300 and the panel 110. The preset direction is perpendicular to the thickness direction. In this embodiment, the preset direction can be understood as the horizontal direction.

[0060] In detail, in this embodiment, one end of the connector 700 is pressed onto the light guide plate 200 and connected to the panel 110 by a threaded fastener.

[0061] The connector 700 includes a first connecting part 710, a second connecting part 720, and a third connecting part 730 connected at an angle in sequence. The first connecting part 710 is pressed onto the light guide plate 200 and connected to the panel 110 by a threaded fastener. The third connecting part 730 is accommodated in the mating groove 320 and fixed to the mating groove 320 by a fastener. It can be understood that the third connecting part 730 is accommodated in the mating groove 320 and can be hidden inside the frame 300.

[0062] In detail, the third connecting part 730 is accommodated in the first groove 321, and the third connecting part 730 can be threadedly connected to the second groove 322 by a threaded fastener.

[0063] In detail, in this embodiment, the panel 110 includes a first plate 111, a second plate 112, a third plate 113, and a fourth plate 114 connected end to end in sequence. The first plate 111 and the second plate 112 are respectively provided with a set of mating bosses 116. The frame 300 includes a first frame 330, a second frame 340, a third frame 350, and a fourth frame 360 ​​connected end to end in sequence. The first frame 330 is located on the side of the first plate 111 away from the light guide plate 200. That is, the mating bosses 116 on the first plate 111 are accommodated in the first groove 321 of the first frame 330. The mating bosses 116 on the first plate 111 are threadedly connected to the second groove 322 of the first frame 330 by threaded fasteners. Similarly, the second frame 340 is located on the side of the second plate 112 away from the light guide plate 200. The mating boss 116 on the second plate 112 is accommodated in the second groove 322 of the second frame 340. The mating boss 116 on the second plate 112 is threadedly connected to the second groove 322 of the second frame 340 by a threaded fastener.

[0064] It should be noted that the third frame 350 and / or the fourth frame 360 ​​extend out of the panel 110 in a preset direction, that is, the third frame 350 will not be obscured by the third panel 113, and / or the fourth frame 360 ​​will not be obscured by the fourth panel 114.

[0065] In detail, in this embodiment, in other words, the third frame 350 and the fourth frame 360 ​​serve as the misaligned portion 370 of the frame 300. The first connecting portion 710 is connected to the third plate 113, and the third connecting portion 730 is connected to the third frame 350. The third connecting portion 730 is accommodated in the first groove 321 of the third frame 350, and the third connecting portion 730 is threadedly connected to the second groove 322 of the third frame 350 by a threaded fastener.

[0066] Of course, in some other embodiments, the number of connectors 700 can be multiple to improve the connection strength between the frame 300 and the panel 110. The first connecting part 710 and the third connecting part 730 of one of the connectors 700 can be connected to the fourth plate 114 and the fourth frame 360 ​​respectively.

[0067] It should be noted that the chassis 400 and the frame 300 are generally made of metal, therefore, the chassis 400 and the frame 300 need to be grounded.

[0068] In this embodiment, the panel 110 is provided with a grounding screw post 140, and a ground wire (not shown in the figure) is provided inside the grounding screw post 140. The chassis 400 is provided with a through hole 410 opposite to the grounding screw. The ceiling light 1 also includes a first abutting screw. The first grounding screw 810 passes through the through hole 410 and is connected to the grounding screw post 140. The major diameter of the first grounding screw 810 is larger than the diameter of the through hole 410.

[0069] Please refer to Figure 7 It should be noted that the major diameter of the first grounding screw 810 is larger than the diameter of the through hole 410. In this embodiment, it should be understood that before the first grounding screw 810 passes through the through hole 410 and is screwed into the grounding screw post 140, the major diameter of the first grounding screw 810 is larger than the diameter of the through hole 410. It can be understood that before the first grounding screw 810 passes through the through hole 410, it will pierce the paint layer of the through hole 410 of the chassis 400. After the first grounding screw 810 is tightened, the chassis 400 is connected to the ground wire under the contact between the first grounding screw 810 and the ground wire, thereby achieving grounding protection.

[0070] Optionally, the panel 110 is also provided with a grounding hole 150, and a grounding wire (not shown in the figure) is provided in the grounding hole 150. The ceiling light 1 also includes a second grounding screw 820, which passes through the grounding hole 150 and is threaded to the frame 300. That is, after the second grounding screw 820 passes through the grounding hole 150 and is threaded to the second groove 322, the frame 300 is connected to the grounding wire, thereby achieving grounding protection.

[0071] In detail, in this embodiment, the light guide plate 200 is arranged in a ring shape. The light guide plate 200 and the panel 110 define a second mounting cavity 210. A second light-emitting element 620 is installed in the second mounting cavity 210. The accommodating cavity 115 has a wire passage opening 119 that communicates with the second mounting cavity 210. It can be understood that the electrical connection wire of the second light-emitting element 620 can enter the accommodating cavity 115 through the wire passage opening 119 and be electrically connected to the terminal. This can effectively prevent the electrical connection wire connected to the second light-emitting element 620 from being exposed, reduce the safety hazards caused by the exposed electrical connection wire, and improve the overall aesthetics of the ceiling light 1.

[0072] In other words, in this embodiment, the accommodating cavity 115 can accommodate the electrical connection wires of the first light-emitting element 610 and the second light-emitting element 620.

[0073] It should be noted that, in some embodiments, in order to improve the aesthetics of the light guide plate 200 of the ceiling light 1, enhance the user's visual effect, and improve the user's comfort, at least a portion of the surface of the light guide plate 200 is provided with decorative patterns, including stone patterns.
