As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0026] Embodiment one

[0027] Referring to Figures 1-2 As shown in the figure, a mounting bracket 1 includes a mounting part 11 and a connecting part 12 protruding from the mounting part 11, the mounting part 11 is annular, the connecting part 12 is a cylinder with one end open, the open end of the connecting part 12 is connected to the inner circumferential edge of the mounting part 11, a plurality of first heat dissipation holes 111 are provided on the mounting part 11, a plurality of second heat dissipation holes 121 are provided on the side wall of the connecting part 12, the non-open end of the connecting part 12 is used to connect with the ceiling 4, and the mounting part 11 is used to connect with the lamp cylinder 21. Specifically, the non-open end of the connecting part 12 can be specifically connected with the ceiling 4 through the screw fastener 5.

[0028] In the above arrangement, since the connecting portion 12 protrudes from the mounting portion 11, when the connecting portion 12 is connected to the ceiling 4, the mounting portion 11 will be spaced apart from the ceiling 4 by a certain space, which will facilitate the flow of air. Thus, when the lamp barrel 21 generates heat, the heat can enter the space through the first and second heat dissipation holes 111 and 121, thereby achieving good heat dissipation effect.

[0029] Embodiment Two

[0030] Referring to Figures 3-5 As shown in FIG. 2, a spliced lamp includes at least two mounting supports 1 of Embodiment One. The outer ring profile of the mounting portion 11 of each mounting support 1 is square. Each mounting portion 11 is connected to a lamp barrel 21 on the side away from the connecting portion 12. The lamp barrel 21 is provided with an LED light emitting unit 22. The lamp barrel 21 is adapted to enclose the outer ring of the mounting portion 11. The outer profile of the lamp barrel 21 is also square. Each lamp barrel 21 has at least one side wall abutting another lamp barrel 21.

[0031] In the above arrangement, based on the same reason, when the lamp barrel 21 generates heat, the heat can enter the space through the first and second heat dissipation holes 111 and 121, thereby achieving good heat dissipation effect. In addition, since the lamp barrel 21 encloses the outer ring of the mounting portion 11, the mounting support 1 is actually shielded by the lamp barrel 21, thereby avoiding exposure of the mounting support 1. The fact that each lamp barrel 21 has at least one side wall abutting another lamp barrel 21 means that the user can splice the lamps according to L-shaped, T-shaped, and square-shaped patterns, thereby achieving double-head lamps, triple-head lamps, four-head lamps, and other lighting needs.

[0032] In this embodiment, a splicing support 3 is arranged between the two adjacent mounting portions 11. The splicing support 3 is provided with a guide groove 31. The bottom of the guide groove 31 is arranged towards the ceiling 4. The guide groove 31 is configured such that when the two opposite side walls of the two adjacent lamp barrels 21 move towards the bottom of the guide groove 31, the two side walls will move closer to each other. Specifically, the number of guide grooves 31 can be two. Thus, when the lamp barrel 21 is installed, the user only needs to push the lamp barrel 21 towards the ceiling 4, and the two opposite side walls of the two adjacent lamp barrels 21 will move closer to each other and abut together, thereby connecting the two adjacent lamp barrels 21 closely and achieving better integrity.

[0033] In this embodiment, the splicing support 3 is provided with a screw hole. The first heat dissipation hole 111 of the mounting portion 11 is in the shape of a strip. A fastening screw 32 is adapted to pass through the first heat dissipation hole 111 and be locked in the screw hole to fix the splicing support 3 to the mounting portion 11. In the above arrangement, by setting the first heat dissipation hole 111 in the shape of a strip, the splicing support 3 can be conveniently installed.

[0034] In the embodiment, the splicing support 3 is provided with a plurality of third heat dissipation holes 33. The third heat dissipation holes 33 can further improve the heat dissipation effect.

[0035] In the embodiment, the mounting part 11 is provided with an extension arm 112 on the side away from the connecting part 12, and the corresponding lamp barrel 21 is fixed on the extension arm 112 by a mounting screw 26. The extension arm 112 can reduce the length of the mounting screw 26, and the installation of the lamp barrel 21 is more convenient.

[0036] In the embodiment, the lamp barrel 21 is detachably connected with a reflector 23 at the end away from the mounting part 11. The reflector 23 can realize the light condensing effect of the LED light unit 22. The detachable reflector 23 can facilitate the maintenance and replacement of the reflector 23. It should be noted that the technical principle of the reflector 23 is prior art, which is not described here.

[0037] In the embodiment, the opposite two side walls of the adjacent two lamp barrels 21 are provided with connecting holes 24, and the connecting holes 24 are provided with connecting screws 25. In this way, the connection between the adjacent two lamp barrels 21 is more reliable. At the same time, since the connecting holes 24 are only arranged on the opposite two side walls, the appearance of the lamp barrel 21 is not damaged.

[0038] In the embodiment, the connecting screw 25 includes a screw rod 251, a screw head 252, and a pull ring 253 arranged on the screw head 252, and the pull ring 253 is rotatably connected with the screw head 252. In this way, the user can directly operate by hand during installation, that is, the pull ring 253 can be rotated to stand up, and then the connecting screw 25 can be directly twisted by hand to connect. After connection and fastening, the pull ring 253 can be rotated to abut against the side wall of the lamp barrel 21, reducing the occupation of the internal space of the lamp barrel 21.

[0039] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process transformation according to the content of the present application specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
