Accordingly, the following detailed description and drawings are merely illustrative of the utility model and are not intended to be exhaustive or to limit the utility model to the precise form disclosed.

Referring to fig. 1 and 3, an embodiment of the utility model provides a ceiling lamp 100, which includes a lamp ceiling structure 10, a lamp cover assembly 20, a light source assembly 30 and a driving power source 50.

The lamp ceiling structure 10 comprises a ceiling disc 1, a lamp disc 2 and a clamping structure 3. The ceiling disc 1 is fixedly installed on the indoor and outdoor top installation foundation, such as an indoor ceiling, an indoor dome, a corridor top wall and the like, the ceiling disc 1 can be fixedly installed on the corresponding installation foundation through expansion screws, and can also be fixedly hung on the installation foundation through a hanging chain and the like, and the ceiling disc is not particularly limited.

The lamp panel 2 is clamped and fixed with the ceiling panel 1 through the clamping structure 3. As shown in fig. 2, the engaging structure 3 includes a groove 31 provided in the suction cup 1 and an engaging piece 32 provided in the lamp cup 2. Wherein the card slot 31 includes a notch 311, a channel 312 communicating with the notch 311 and extending in a circumferential direction. During installation, a user can manually lift the lamp panel 2 and upwards lock the lamp panel 2 onto the ceiling disc 1, meanwhile, the clamping piece 32 on the lamp panel 2 is buckled into the notch 311 on the ceiling disc 1, then the user can manually rotate the lamp panel 2 along the extending direction of the channel 312, and then the clamping piece 32 is clamped into the channel 312, so that the clamping operation of the lamp panel 2 and the ceiling disc 1 is completed.

In some alternative embodiments, to facilitate the rotational snap-fit mounting of the lamp tray 2 to the ceiling tray 1, it is envisioned that the snap-in groove 31 may be provided on the lamp tray 2 and the snap-in member 32 may be provided on the ceiling tray 1, without limitation.

In order to avoid the clamping member 32 from being accidentally removed from the clamping groove 31, the groove 312 is provided with a limiting portion 313. Specifically, the stopper 313 is a protrusion formed on the suction cup 1, the protrusion being provided across the channel 312. In operation, the user lifts the lamp panel 2 to be fastened to the suction disc 1, the lamp panel 2 can rotate relative to the suction disc 1 so that the clamping member 32 is clamped into the channel 312 via the notch 311, and then the clamping member 32 passes over the protrusion and is in limited abutment with the protrusion, and the protrusion can prevent the clamping member 32 from rotating and exiting in the opposite direction.

In order to make the stress at the clamping position between the lamp panel 2 and the suction top panel 1 more uniform, and to realize more firm installation between the lamp panel 2 and the suction top panel 1, in some embodiments, the clamping grooves 31 and the clamping pieces 32 are respectively provided with a plurality of clamping grooves 31 corresponding to the plurality of clamping pieces 32, the plurality of clamping grooves 31 are uniformly arranged on the suction top panel 1 along the circumferential direction, the plurality of clamping pieces 32 are uniformly arranged on the lamp panel 2 along the circumferential direction, and in particular, two, three or more clamping pieces which are oppositely arranged can be adopted, the clamping grooves 31 and the clamping pieces 32 are not limited in number and distribution, and the clamping grooves 31 and the clamping pieces 32 are corresponding to each other.

To facilitate the mounting of the clip 32, in some embodiments, the lamp panel 2 is provided with a mounting portion 22 for mounting the clip 32, the mounting portion 22 protruding upward from the upper surface of the lamp panel 2. The clamping member 32 may be screw-connected to the mounting portion 22.

Since the ceiling tray 1 is usually mounted against a mounting base such as a ceiling, in order to avoid inconvenience in mounting caused by the clip member 32 touching the mounting base after the lamp tray 2 is clipped onto the ceiling tray 1, in some embodiments, the upper surface of the ceiling tray 1 is formed with the accommodating portion 11 in a downward recess, and the clip groove 31 is disposed in the accommodating portion 11. The suction top plate 1 is provided with a first concave portion 13 and a second concave portion 14 which are concave downward, a notch 311 is positioned in the first concave portion 13, and a channel 312 is connected between the first concave portion 13 and the second concave portion 14. The specific ones are not limited.

In this way, after the lamp panel 2 is mounted on the suction disc 1 in a clamped manner, the clamping member 32 is accommodated in the second concave portion 14, and the second concave portion 14 is accommodated in the accommodating portion 11 of the suction disc 1, so that the top of the clamping member 32 is not easy to touch the mounting base such as the ceiling, and the problem of mounting inconvenience such as being abrupt is avoided.

Since the shapes of the ceiling disc 1 and the lamp disc 2 are different, for example, the shape of the ceiling disc 1 is circular, the shape of the lamp disc 2 is rectangular, in order to facilitate the fast clamping of the lamp disc 2 onto the ceiling disc 1 during the installation process of the lamp disc 2 and the ceiling disc 1, in some embodiments, as shown in fig. 4, 5 and 6, the outer peripheral edge of the ceiling disc 1 is provided with a first positioning portion 15 protruding downward and extending circumferentially, the lamp disc 2 is provided with a second positioning portion 23 protruding upward and extending circumferentially, and the first positioning portion 15 is matched with the second positioning portion 23. The shape of the first positioning portion 15 and the shape of the second positioning portion 23 are both annular, and the outline size of the first positioning portion 15 is larger than that of the second positioning portion 23. Since the outline size of the first positioning portion 15 is larger than that of the second positioning portion 23, the first positioning portion 15 is wrapped outside the second positioning portion 23. In other alternative embodiments, the shapes of the first and second positioning portions are not limited to annular shapes, but other shapes are also possible, and the outline dimensions of the first and second positioning portions are not limited to different arrangements, and may be mutually overlapped, nested, staggered, etc., which is not particularly limited.
