[0049] First embodiment, reference Figures 1-13 .

[0050] This embodiment provides a ceiling light structure, including a light fixture chassis, a bottom cover placed on the chassis, and multiple light source modules (such as...). Figure 12 The bottom cover is provided with a driving component for driving the light source module to open and close; the light source module is rotatably disposed on the front side of the bottom cover, and multiple light source modules are distributed circumferentially on the bottom cover; the multiple light source modules have a first position and a second position relative to the bottom cover; when the multiple light source modules rotate to the first position, the multiple light source modules are folded together and placed on the bottom cover (e.g., Figure 2 When the multiple light source modules are rotated to the second position, the multiple light source modules unfold outward relative to the bottom cover (e.g. Figure 4 The light source module extends beyond the bottom cover; the bottom cover is detachably mounted on the chassis, and by rotating the light source module, the bottom cover can be adapted to at least two different sizes of chassis.

[0051] By integrating the driver assembly and light source module into a single unit on the base cover, installation steps are reduced. Users no longer need to install the driver and light source modules separately; simply installing the integrated base cover onto the chassis completes the installation. The detachable design of the base cover and chassis significantly improves installation efficiency. After the integrated base cover is installed and connected to mains power via the driver assembly, a lampshade can be attached to form a ceiling light for illumination. The driver assembly connects to mains power via terminal blocks, female connectors, and male connectors. The terminal blocks connect to the driver assembly, the female connectors connect to the terminal blocks, and the male connectors plug into the female connectors. The male connectors are used to connect to mains power.

[0052] The light source module can be rotated to achieve both folded and unfolded states, adapting to different sized chassis, such as... Figure 12 When the chassis size is small, multiple light source modules can be rotated and folded onto the bottom cover for installation inside the chassis; such as Figure 13 When the chassis is large, multiple light source modules can be rotated and unfolded onto the chassis, expanding the light-emitting area and ensuring uniform light emission even on a larger chassis. The rotation of the light source modules enhances the versatility and flexibility of the lamps, meeting the needs of more users and solving the problem of traditional lamps being unable to be universally compatible.

[0053] The rotating structure of the light source module specifically includes a bottom cover comprising threaded posts (such as...). Figure 1 The light source module includes a through hole, through which it is fitted onto the threaded post; the threaded post includes an external thread, and a threaded cap is screwed onto the threaded post via the external thread; a silicone sheet is fitted between the threaded cap and the light source module; tightening the threaded cap compresses the silicone sheet and presses down on the light source module (e.g., ...). Figure 7 The light source module can rotate around the threaded post through the through hole.

[0054] The light source module is fitted onto the threaded post through a through hole and secured by tightening the threaded cap to compress the silicone sheet. This structure not only firmly secures the light source module, but also makes the fixing method simple and easy. Users can easily install the light source module on the bottom cover, and it is also easy to disassemble when maintenance or replacement of the light source module is required, thus improving the user experience.

[0055] When the threaded cap is tightened, the silicone sheet is compressed, producing a certain degree of elastic deformation, thus firmly pressing the light source module in place and ensuring it does not loosen during use. The silicone sheet has excellent damping properties; utilizing this damping effect, the light source module maintains a certain degree of rotational flexibility after being fixed. Users can easily adjust the angle of the light source module as needed to achieve the best lighting effect, and the damping effect of the silicone sheet can also maintain a certain rotation angle without external force, keeping the light source module in an unfolded or retracted state.

[0056] The mounting structure of the bottom cover and chassis is as follows: the threaded post is hollow and has internal threads, and a screw assembly (such as...) is screwed onto the threaded post through the internal threads. Figure 1 The screw assembly includes a screw and a mounting part (such as...). Figure 7 The screw is screwed onto the threaded post, and the screw is connected to the mounting part, which is located on the back of the bottom cover; the bottom cover is detachably connected to the chassis via the mounting part; the distance between the mounting part and the bottom cover can be changed by rotating the screw (e.g., ...). Figure 10 , Figure 11 ).

[0057] like Figure 13 The screw assembly design allows users to change the distance between the mounting part and the base cover by rotating the screw, thus achieving flexible height adjustment of the lamp and solving the problem of traditional lamps where the height cannot be adjusted after the base cover is fixed. The height-adjustable design allows users to install and use it directly on existing lamps. The base cover, through the adjustment of the screw assembly, maintains a gap with the chassis, effectively isolating the original driver and light source structures on the chassis. This eliminates the need to remove the original driver and light source, improving the lamp's applicability.

[0058] like Figure 1 The specific structure of the bottom cover, driving assembly, and light source module is as follows: the bottom cover is an annular bottom cover, and the light source module has an arc-shaped structure; multiple light source modules are assembled around the bottom cover after being gathered together (e.g., Figure 2 The inner ring of the annular bottom cover is provided with limiting ribs (such as...). Figure 6 The light source module, when retracted, engages with the limiting rib for positioning.

[0059] The design of the ring-shaped bottom cover and the arc-shaped light source module allows multiple light source modules to be tightly packed on the bottom cover, forming a complete ring-shaped lighting structure, improving the space utilization and overall aesthetics of the lamp. The design of the limiting ribs effectively restricts the position of the light source modules, ensuring that the light source modules fit tightly with the bottom cover after being packed, preventing the light source modules from shifting or loosening during use, and guaranteeing the lighting effect of the lamp.

[0060] The driving component includes a light source connection cable (such as a light source connection line) for connecting the light source module. Figure 1 The inner ring of the bottom cover is provided with a cable routing channel (such as...). Figure 6 The light source connection wire is routed through the wiring channel. By setting the wiring channel along the inner ring of the bottom cover, the light source connection wire can be neatly hidden inside the wiring channel, avoiding messy wiring and improving the overall aesthetics of the lamp.

[0061] The rotating engagement structure of the light source module is such that a connecting rod assembly (such as...) is mounted on the back of the bottom cover. Figure 3 The linkage assembly includes a connecting rod, which is movably connected to the bottom cover; the outer edge of the bottom cover is provided with a notch (e.g., Figure 5 One end of the connecting rod is connected to the light source module through the notch.

[0062] The light source module can be rotated open, but the maximum range of rotation is limited by the connecting rod (e.g., Figure 4 The connecting rod also helps to hold the light source assembly in place, preventing it from sagging excessively during normal unscrewing and use. The movable connection between the connecting rod and the bottom cover provides additional support for the light source module, enhancing its stability during use and ensuring that the lighting effect of the lamp is not affected.

[0063] like Figure 8 The bottom cover has a locking point on its back, and the end of the connecting rod away from the light source module has a sliding groove. The sliding groove is arranged along the length of the connecting rod, and the locking point is inserted into the sliding groove and slides along it. The connecting rod is movably connected to the bottom cover through the sliding groove and the locking point. Users can adjust the position of the connecting rod through simple sliding operations. The cooperation between the locking point and the sliding groove can achieve a reliable connection between the connecting rod and the bottom cover, while allowing the connecting rod to slide within the sliding groove. This ensures the stability of the connection and provides a certain range of motion, making the adjustment of the lamp more flexible.

[0064] One end of the connecting rod is connected to the light source module via a snap-fit ​​(e.g., ...). Figure 9 The snap-fit ​​connection method ensures a secure connection between the connecting rod and the light source module, preventing loosening or detachment during use. It also facilitates user disassembly and replacement of the light source module, making it convenient for users to maintain and upgrade the lighting fixtures.

[0065] Second embodiment, reference Figures 14-15 .

[0066] Based on the ceiling light structure provided in the first embodiment, this embodiment provides a detachable connection structure between the bottom cover and the chassis. Specifically:

[0067] The mounting part includes a magnet, and the chassis is a metal chassis; the mounting part is magnetically attracted to the chassis by the magnet, so that the bottom cover is fixed to the chassis (e.g., Figure 14 By utilizing the magnetic attraction of magnets, the mounting part is fixed to the metal chassis. Without complicated installation tools and steps, users can easily complete the installation of the lamp, further improving the convenience of installation.

[0068] Alternatively, you can choose to apply adhesive backing patches to the plastic chassis (such as...). Figure 15 The adhesive backing is magnetic and can be attracted to a magnet. By utilizing the magnetic attraction between the adhesive backing and the magnet, the mounting part is fixed to the chassis, thus achieving the installation of the bottom cover.

[0069] Third embodiment.

[0070] Based on the ceiling light structure provided in the first embodiment, this embodiment provides a detachable connection structure between the bottom cover and the chassis. Specifically:

[0071] The chassis includes a rotating mounting hole, which includes a limiting hole. The mounting part is placed inside the rotating mounting hole. Rotating the bottom cover causes the mounting part to rotate until it engages with the limiting hole, thus fixing the bottom cover to the chassis. The rotating action causes the mounting part to engage with the corresponding limiting hole, thereby fixing the bottom cover. This rotating snap-fit ​​structure is a common connection structure in lighting fixtures and will not be described in detail here.

[0072] The bottom cover is secured to the chassis by rotating the mounting holes and using the limiting holes. This structure ensures a tight connection between the bottom cover and the chassis, preventing the lamp from loosening or shaking during use and improving the lamp's stability. During installation, the user simply places the mounting part into the rotating mounting holes and rotates the bottom cover to complete the installation. The operation is simple and easy, reducing installation difficulty and improving the user experience.

[0073] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
