Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0022] Example 1 Combination Figures 1-7 This application provides a ceiling light, including a lampshade assembly 10 and a lamp body assembly 20; the lampshade assembly 10 includes a cover 11 and a lampshade base 12 for the cover 11 to be inserted and fixed; the lamp body assembly 20 is detachably connected to the lampshade assembly 10, and a light source plate 21 is provided on the end face of the lamp body assembly 20 facing the lampshade assembly 10.

[0023] In one embodiment, the lampshade base 12 is annularly arranged, and a groove 121 is formed on the edge of one end face for the edge of the cover 11 to be inserted and fixed. The cover 11 has a rib 111 protruding from the edge of the end face facing the lampshade base 12, which is configured to cooperate with the groove 121 of the lampshade base 12. The thickness of the rib 111 of the cover 11 is smaller than the groove 121 of the lampshade base 12, so that the cover 11 can be inserted into the lampshade base 12.

[0024] In one embodiment, after the cover 11 and the lampshade base 12 are aligned and inserted, they need to be connected by high-frequency induced welding, or by ultrasonic or glue application, in order to improve the structural integrity of the lampshade assembly 10.

[0025] In this embodiment, the lampshade assembly 10 after plugging and fixing is a single piece, without any extra parts such as screw heads, and has an aesthetically pleasing appearance. At the same time, it meets the requirements of structural strength and waterproofing. Complex structures can also be made on the lampshade base 12 without affecting its functionality.

[0026] In addition, the lamp body assembly 20 includes a chassis 22; one end face of the chassis 22 is disposed against an external fixing surface; one end of the light source plate 21 is pivotally connected to the inner edge of the other end face of the chassis 22.

[0027] In one embodiment, a detachably connected fixing plate 211 is provided at one end of the light source plate 21; a rotating bracket 221 is provided on the inner edge of the other end face of the chassis 22, and a rotating shaft that cooperates with the rotating bracket 221 is provided at the free end of the fixing plate 211; the rotating shaft is installed on the rotating bracket 221, allowing the light source plate 21 to rotate around the rotating shaft on the other end face of the chassis 22. The fixing plate 211 and the light source plate 21 are fixedly installed with bolts, and the rotating bracket 221 and the chassis 22 are fixedly installed with bolts. In this embodiment, the rotating shaft is mounted on the rotating bracket 221, allowing the rotating shaft to rotate around itself. Since the rotating shaft is fixedly installed on the edge of the fixing plate 211, the fixing plate 211 and the fixedly connected light source plate 21 can rotate around the rotating bracket 221, achieving the rotational opening and closing effect of the light source plate 21 and the chassis 22.

[0028] In one embodiment, the chassis 22 is a cylindrical structure with one end open, and its top end is fixedly installed to an external fixing surface, which is usually the ceiling. That is, the chassis 22 is fixed in an open-end-facing-down posture. In this embodiment, when the light source board 21 is rotated to open and close, it rotates towards the outside, which makes it convenient for maintenance personnel to check the wiring part on the rear end of the light source board 21.

[0029] In one embodiment, the rotation of the light source plate 21 is greater than 90°.

[0030] In one embodiment, the light source plate 21 has a circular structure and its diameter is at most equal to the inner diameter of the opening end face on the chassis 22, so as to ensure that the light source plate 21 is planar with the opening end face of the chassis 22 when it is fixed, thereby reducing the overall thickness of the ceiling light.

[0031] In this embodiment, the fixing plate 211 and the rotating bracket 221 enable the light source board 21 to rotate and open with the chassis 22. Without excessive disassembly of the lamp body assembly 20, the wiring part at the rear end of the light source board 21 can be viewed, reducing the difficulty of maintenance and installation.

[0032] In addition, the lamp body assembly 20 includes a buckle 222 and a fixing hole 212; the buckle 222 is disposed on the other end face of the chassis 22 and is symmetrically arranged with the rotating bracket 221 along the central axis of the chassis 22; the fixing hole 212 is opened on the light source plate 21 and is symmetrically arranged with the fixing piece 211 along the central axis of the light source plate 21; the buckle 222 and the fixing hole 212 are fitted together to fix the light source plate 21 and the chassis 22.

[0033] In one embodiment, the buckle 222 is protruding, the fixing hole 212 and the buckle 222 are disposed in a non-empty manner, and the free end of the buckle 222 is provided with a deformable folded edge, which is used to engage with the fixing hole 212 and the buckle 222 on the disengagement path, so as to realize the engagement and fixation of the buckle 222 and the fixing hole 212, as well as the engagement and fixation of the light source plate 21 and the chassis 22.

[0034] In this embodiment, the light source board 21 and the chassis 22 are assembled and fixed by the buckle 222 and the fixing hole 212.

[0035] In addition, the lamp body assembly 20 also includes a limiting step 223 disposed on the other end face of the chassis 22; the limiting step 223 supports the light source plate 21 in the locked state.

[0036] In one embodiment, the limiting steps 223 are provided close to the inner edge of the other end face of the chassis 22, and there are multiple steps, which are distributed in a circumferential interval to effectively balance the supporting force of the light source plate 21 and keep it in a horizontal and fixed state.

[0037] In one embodiment, the limiting step 223 is bent into a sheet shape to reduce its own weight and the area it occupies in the chassis 22.

[0038] In this embodiment, the structural stability of the lamp assembly 20 is further ensured by setting the limiting step 223.

[0039] In addition, a limiting rib 224 is formed on the outer side of the lamp body assembly 20; a screw through hole 122 is formed on the side of the lamp cover assembly 10, which is aligned with the limiting rib 224; external fasteners pass through the screw through hole 122 and are fixed on the limiting rib 224 to fix the lamp cover assembly 10 and the lamp body assembly 20.

[0040] In one embodiment, a limiting rib 224 protrudes from the outer side of the lamp body assembly 20; a screw through hole 122 protrudes from the upper end face of the lamp cover assembly 10, and a waterproof rib for the lamp cover is also protruding from the inner edge of the screw through hole 122. A sealing ring groove is formed on the outer edge of the light source plate 21 on the lamp body assembly 20. When the limiting rib 224 and the screw through hole 122 are aligned, the waterproof rib of the lamp cover assembly 10 presses against the sealing ring in the sealing ring groove of the lamp body assembly 20.

[0041] In one embodiment, the number of limiting ribs 224 and screw through holes 122 are equal, both being four, and they are distributed at circumferential intervals along the lamp body assembly 20 and the lamp cover assembly 10, respectively.

[0042] In one embodiment, the outer edge of the lamp body assembly 20 is smaller than the outer edge of the lamp cover assembly 10. Specifically, the diameter of the base 22 is smaller than the diameter of the lamp cover assembly 10, and the bottom of the base 22 has a slope, which makes it easier to rotate the lamp cover assembly 10 and fix the screws.

[0043] In this embodiment, the lamp body assembly 20 and the lamp cover assembly 10 are aligned by screw through holes 122 and limiting ribs 224, and the connection is reinforced by external fasteners.

[0044] In addition, the lampshade assembly 10 and the lamp body assembly 20 are provided with a guide structure 40 on their sides; the lampshade assembly 10 and the lamp body assembly 20 are roughly positioned by the guide structure 40, and under the guidance of the guide structure 40, the lampshade assembly 10 rotates to align the screw through hole 122 with the limiting rib 224.

[0045] In one embodiment, the guide structure 40 includes a guide block 41 disposed on the outer side of the waterproof rib of the lampshade, and a guide groove 42 disposed on the side of the lamp body assembly 20. The guide block 41 and the guide groove 42 are provided with corresponding slopes. When the lampshade assembly 10 is rotated, the guide block 41 will slide into the guide groove 42 to lock the lampshade assembly 10 and the base 22 on the lamp body assembly 20.

[0046] In one embodiment, the guide structure 40 has four sets and is distributed at intervals around the perimeter of the ceiling light.

[0047] In this embodiment, when the lampshade assembly 10 is pushed upward toward the lamp body assembly 20, the guide structure 40 facilitates the alignment of the lampshade assembly 10 and the base 22 of the lamp body assembly 20, and provides a coarse positioning and guiding foundation for the alignment of the screw through hole 122 and the limiting rib 224, thereby achieving the alignment and assembly of the lampshade assembly 10 and the lamp body assembly 20 more quickly.

[0048] Additionally, it includes a detachable decorative cover 30 that covers the outer end face of the lampshade assembly 10; screw holes 122 and guide structures 40 are exposed on the decorative cover 30.

[0049] In one embodiment, a folded edge is formed along the inner edge of one end face of the decorative cover 30, and a through hole is formed on the folded edge, which is configured to cooperate with the through hole on the upper end face of the lampshade assembly 10, allowing screws to pass through and fix the lampshade assembly 10 and the decorative cover 30. In this embodiment, there are three through holes, which are evenly spaced on the folded edge of the inner edge of the decorative cover 30.

[0050] In one embodiment, the height of the decorative cover 30 is at least equal to the height from the upper end to the bottom end of the lampshade assembly 10, so as to ensure that the decorative cover 30 blocks the junction line between the upper cover 11 and the lampshade base 12 of the lampshade assembly 10.

[0051] In one embodiment, the inner edge of the decorative cover 30 is provided with a limiting groove 31 for the screw through hole 122 to pass through.

[0052] In this embodiment, the height of the decorative cover 30 is adjustable, but this does not affect the difficulty of screwing the lampshade assembly 10 and the decorative cover 30 into the chassis 22 after assembly, making it easy to disassemble, repair and replace.

[0053] In summary, this embodiment proposes a ceiling light. By adjusting the structure of the lampshade assembly, the waterproof rating of the lampshade assembly and the ceiling light is improved while ensuring its aesthetics. At the same time, the assembly method of the light source board and the upper chassis of the lamp body assembly is adjusted to reduce the installation and maintenance difficulty of the light source board. Furthermore, the installation difficulty of the ceiling light is further reduced by using a guide structure to fix the screw-on and snap-fit ​​structure between the lampshade assembly and the upper chassis of the lamp body assembly.
