[0002] Ceiling lights are a type of commonly used lamps, which are usually installed on the ceiling or roof to meet basic lighting needs. They are favored by consumers because of their advantages such as saving indoor space and high flexibility in installation locations. Almost every household will install more or less ceiling lights.

[0003] Taking the installation of ceiling lights on the ceiling as an example, the installation method is generally to fix them by locking screws, and then the ceiling is usually also composed of multiple cut panels assembled, so there is a tendency for cumulative tolerances to occur, resulting in the ceiling being unable to be completely attached to the installation groove of the ceiling when the ceiling light is screwed to the ceiling, that is, part of the ceiling light will protrude from the ceiling surface, creating a certain sense of abruptness and oppression, destroying the coordination and neatness of the overall decoration style, and affecting the user experience. Utility Model Content

[0004] In view of this, the utility model provides a ceiling lamp and a lighting system, which are used to solve the problem in the prior art that installation size errors cause abruptness and oppression, affecting the decoration effect and user experience.

[0005] The utility model provides a ceiling lamp, which comprises:

[0006] a lamp housing, wherein a lamp panel is installed inside the lamp housing; and

[0007] A mounting tube, wherein the mounting tube is arranged on the back side of the lamp housing, and the outer peripheral wall of the mounting tube cooperates with the back side of the lamp housing to form a positioning step; a window is provided on the end face of the mounting tube away from the lamp housing, and the side wall of the window is connected with an elastic connecting piece, and the elastic connecting piece is bent toward the inside of the barrel cavity of the mounting tube, and the elastic connecting piece is provided with a threaded hole.

[0008] In one embodiment, the elastic connecting piece includes a straight section and a corrugated section, one end of the corrugated section is connected to the straight section, the other end of the corrugated section is connected to the side wall of the window, and the threaded hole is formed on the straight section.

[0009] In one embodiment, at least two of the windows and the elastic connecting pieces are provided, and at least two of the windows are arranged at intervals along the circumferential direction of the mounting tube, and the elastic connecting pieces are assembled with the windows in a one-to-one correspondence.

[0010] In one embodiment, a clamping component is arranged on the inner wall of the lamp housing, and a bayonet opening is formed in the mounting cylinder. The clamping component is in snap fit with the bayonet opening so that the lamp housing and the mounting cylinder are assembled and fixed.

[0011] In one embodiment, the bayonet opening includes a communicating inlet and outlet section and a clamping section. The inlet and outlet section extends along the height direction of the mounting cylinder, and the clamping section extends along the circumferential direction of the mounting cylinder. The clamping component includes a clamping block, and the clamping block slides into the clamping section from the inlet and outlet section and can be slidably clamped therein.

[0012] In one embodiment, the clamping component further includes a support piece. The support piece is arranged on the clamping block, and the support piece has a support portion which abuts against the inner wall of the mounting cylinder.

[0013] In one embodiment, the clamping component further includes a fastening connecting piece.

Then, screw the screw into the threaded hole from the inner side direction of the ceiling. As the screw is continuously turned, and with the transmission effect of the thread pair, the elastic connecting piece that bends towards the inner side of the cylinder cavity of the installation cylinder is forced to deform and gradually deflect towards the direction of the window. During this process, the deformed elastic connecting piece will generate an elastic tensile force on the installation cylinder, that is, pull the installation cylinder towards the depth direction of the installation groove. In other words, the deflection movement stroke generated by the deformation of the elastic connecting piece can be synchronously converted into the movement stroke of the installation cylinder. By adding this movement stroke to the thread segment length of the screw, the gap generated between the ceiling lamp and the installation groove due to the cumulative tolerance of the ceiling can be compensated, so as to ensure that the ceiling lamp can be completely installed into the installation groove, avoid part of the ceiling lamp protruding from the notch of the installation groove, thus avoiding a sense of abruptness and depression, protecting the coordination and neatness of the overall interior decoration style, and improving the use experience. At the same time, the formed positioning step can be adaptively engaged with the preset positioning boss in the installation groove to realize the installation positioning of the ceiling lamp, further ensuring the installation position accuracy of the ceiling lamp.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figure 1As shown, there is a ceiling lamp 100 of an embodiment, which includes a lamp housing 10 with a lamp board installed inside; and an installation cylinder 20 arranged on the back of the lamp housing 10. A positioning step 30 is formed by the cooperation of the outer peripheral wall of the installation cylinder 20 and the back of the lamp housing 10. A window 21 is opened on the end face of the installation cylinder 20 away from the lamp housing 10. An elastic connecting piece 22 is connected to the side wall of the window 21. The elastic connecting piece 22 is bent towards the inner part of the cavity of the installation cylinder 20, and a threaded hole is opened on the elastic connecting piece 22.

[0033] Both the lamp housing 10 and the installation cylinder 20 are in a cylindrical structure, and the material can be one of plastic, aluminum alloy, etc.

[0034] The diameter of the lamp housing 10 is larger than that of the installation cylinder 20, and the lamp housing 10 and the installation cylinder 20 are coaxially arranged, so that a uniformly shaped and sized annular positioning step 30 can be formed.

[0035] The lamp board is specifically composed of a PCB board and LED lamp beads soldered on the PCB board, with high illuminance, energy saving and consumption reduction, and excellent economic performance in use.

[0036] The elastic connecting piece 22 is rectangular, and correspondingly, the window 21 is also rectangular. The elastic connecting piece 22 is integrally connected to a side surface of the window 21 through one side surface. It can be understood that the elastic connecting piece 22 can be formed by cutting and processing the installation cylinder 20, and the three adjacent side surfaces of the elastic connecting piece 22 are separated from the three adjacent side surfaces of the window 21.

[0037] Implementing the embodiments of the present utility model will have the following beneficial effects: When installing the ceiling lamp 100 of this solution, first assemble the installation cylinder 20 and the lamp housing 10 into an integral structure, then align the installation cylinder 20 with a preset installation groove on the ceiling and insert it into the groove, and then screw a screw into the threaded hole from the inner side direction of the ceiling. As the screw is continuously screwed, and with the transmission effect of the thread pair, the elastic connecting piece 22 that bends towards the inner side of the cylinder cavity of the installation cylinder 20 is forced to deform and gradually deflect towards the direction of the window 21. During this process, the deformed elastic connecting piece 22 will generate an elastic pulling force on the installation cylinder 20, that is, pull the installation cylinder 20 in the depth direction of the installation groove. In other words, the deflection movement stroke generated by the deformation of the elastic connecting piece 22 can be synchronously converted into the movement stroke of the installation cylinder 20. By superimposing this movement stroke on the length of the threaded section of the screw, the gap generated between the ceiling lamp 100 and the installation groove due to the cumulative tolerance of the ceiling can be compensated, so as to ensure that the ceiling lamp 100 can be completely installed in the installation groove, prevent part of the ceiling lamp 100 from protruding out of the notch of the installation groove, thus avoiding a sense of abruptness and depression, protecting the coordination and neatness of the overall interior decoration style, and enhancing the usage experience. At the same time, the formed positioning step 30 can be adaptively engaged with a preset positioning boss in the installation groove to realize the installation positioning of the ceiling lamp 100, further ensuring the installation position accuracy of the ceiling lamp 100.

[0038] Please refer to Figure 1 , in one of the embodiments, the elastic connecting piece 22 includes a straight section 222 and a corrugated section 223. One end of the corrugated section 223 is connected to the straight section 222, and the other end of the corrugated section 223 is connected to the side wall of the window 21. The threaded hole is formed on the straight section 222. Compared with the straight section 222, the corrugated section 223 has better deformation ability and can generate a more significant elastic pulling force to be applied to the installation cylinder 20, and has a better pulling effect on the installation cylinder 20 towards the deep part of the installation groove. In addition, the straight section 222 is connected to the side wall of the window 21 (i.e., the installation cylinder 20) through the corrugated section 223. When the elastic connecting piece 22 is pulled by the screw and undergoes deformation close to the limit, the corrugated section 223 is not likely to break and will not produce irreversible deformation, ensuring the service life of the ceiling lamp 100.

[0039] Preferably, in one of the embodiments, there are at least two windows 21 and elastic connecting pieces 22. The at least two windows 21 are arranged at intervals along the circumferential direction of the installation cylinder 20, and the elastic connecting pieces 22 are assembled in one-to-one correspondence with the windows 21. For example, in this application, both the window 21 and the elastic connecting piece 22 are provided with two and are evenly spaced along the circumferential direction of the installation cylinder 20. During installation, the two elastic connecting pieces 22 can ensure a uniform pulling force on the ceiling lamp 100, preventing the ceiling lamp 100 from tilting and being unable to be smoothly installed in the installation groove.

[0040] Please refer to Figures 2 to 4 Figures 2 to 4 , in one embodiment, a clamping component 40 is arranged on the inner wall of the lamp housing 10, and a bayonet 23 is formed in the mounting cylinder 20. The clamping component 40 is snap-fitted with the bayonet 23 to fix the lamp housing 10 and the mounting cylinder 20 in an assembled manner. Thereby, the lamp housing 10 and the mounting cylinder 20 are assembled into an integral structure, improving the overall structural stability and application reliability of the ceiling lamp 100.

[0041]

[0041] To facilitate the assembly and fixation or disassembly of the lamp housing 10 and the mounting cylinder 20, in the above embodiment, the bayonet 23 includes a communicating inlet and outlet section 231 and a clamping section 232. The inlet and outlet section 231 extends along the height direction of the mounting cylinder 20, and the clamping section 232 extends along the circumferential direction of the mounting cylinder 20. The clamping component 40 includes a clamping block 41. The clamping block 41 slides into the inlet and outlet section 231 and can be slidably clamped into the clamping section 232. Under this structural design, during installation, only the inlet and outlet section 231 needs to be aligned with the clamping block 41, and then the lamp housing 10 and the mounting cylinder 20 are moved closer to each other. The clamping block 41 can be snapped into the inlet and outlet section 231 and move to one end in the length direction of the clamping section 232. Then, immediately, the lamp housing 10 and the mounting cylinder 20 are rotated in the opposite direction by a certain angle. During the process, the clamping block 41 can slide along the clamping section 232 all the time and finally move to the other end in the length direction of the clamping section 232. Thus, the assembly connection between the lamp housing 10 and the mounting cylinder 20 can be completed. When disassembly is required, just operate according to the above opposite steps. The installation and disassembly operations of the lamp housing 10 and the mounting cylinder 20 are simple, convenient, labor-saving, and highly feasible.

[0042]

[0042] In addition, in another embodiment, the clamping component 40 further includes a support piece 42. The support piece 42 is arranged on the clamping block 41, and the support piece 42 has a support portion 421. The support portion 421 abuts against the inner wall of the mounting cylinder 20. On the one hand, the support piece 42 abuts against the inner wall of the mounting cylinder 20 to realize the installation positioning of the mounting cylinder 20; on the other hand, when the lamp housing 10 and the mounting cylinder 20 are assembled, the support piece 42 can also continuously support and reinforce the mounting cylinder 20, improving the overall structural strength of the ceiling lamp 100.

[0043]

[0043] Furthermore, the clamping component 40 further includes a fastening connector 43. The support piece 42 is provided with a first mounting hole, and the mounting cylinder 20 is provided with a second mounting hole opposite to the first mounting hole. The fastening connector 43 is fixed by passing through the first mounting hole and the second mounting hole. In this way, the support piece 42 and the mounting cylinder 20 can be locked and fixed through the fastening connector 43, improving the relative structural stability between the support piece 42 and the mounting cylinder 20.

[0044] For example, the fastening and connecting member 43 can be a screw. The first mounting hole is a through hole, and the second mounting hole is a threaded hole. After the screw passes through the through hole, it is screwed into the threaded hole. This threaded connection method has a simple structure, high connection strength, and convenient installation and disassembly operations.

[0045] In yet another embodiment, the support piece 42 further has a bent portion 422 connected to the support portion 421. The clamping block 41 is provided with a socket, and the connection portion between the bent portion 422 and the support portion 421 is inserted into the socket. The support portion 421 and the bent portion 422 are arranged at an angle, so as to form double-sided limits with the clamping block 41, preventing the support piece 42 from displacing relative to the clamping block 41 or even becoming loose from the clamping block 41.

[0046] The present utility model also proposes an illumination system, which includes a control switch and the ceiling lamp 100 described in any of the above embodiments. The ceiling lamp 100 is electrically connected to the control switch.

[0047] The control switch can be installed at positions such as on a wall, and is used to control the lighting or extinguishing of the ceiling lamp 100, the switching of lamp colors, etc.

[0048] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0049] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
