A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0039] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0040] like Figure 1 As shown, this embodiment provides a lamp including a U-shaped light ring 1. The number of light rings 1 can be one or more. In the case of multiple light rings 1, the multiple light rings 1 are concentrically arranged, and all light rings 1 have different outer diameters. All light rings 1 can be coplanar and fixed to a main frame 2; alternatively, they can be non-coplanar and arranged into the desired shape before being fixed to the main frame 2.

[0041] like Figure 1As shown, preferably, the power of the lamp in this embodiment is 300W, and it includes three lamp rings 1. Figure 2 As shown, in other embodiments, the power of the lamp can also be 200W, and it includes two light rings 1.

[0042] like Figures 1-6 As shown, the light ring 1 includes four profiles 11, four corner connectors 12, and four circuit boards 13. The four profiles 11 are arranged in a U-shaped pattern, with the four corner connectors 12 located at the four corners of the U-shaped pattern. Two adjacent profiles 11 are connected by a corner connector 12. Each profile 11 has a first plug-in portion at each end, and each corner connector 12 has a second plug-in portion at each end. The first and second plug-in portions mate with each other. One of the first and second plug-in portions is provided with a snap-fitting protrusion 122, and the other has a snap-fitting groove 112 that snaps into place with the snap-fitting protrusion 122. Each circuit board 13 corresponds to a profile 11 and is fixed to the profile 11. The circuit boards 13 are provided with light-emitting elements, which emit light when power is supplied to the circuit boards 13.

[0043] The circuit board 13 is fixed on the profile 11, and the ends of two adjacent profiles 11 are connected by a corner connector 12. The corner connector 12 and the profile 11 are connected by plugging. The plug-in assembly method is simple and fast, with low labor intensity and high assembly efficiency, which reduces the production cost of the lamp.

[0044] Specifically, the profile 11 is made of aluminum, and the corner connector 12 is made of plastic. A plurality of light-emitting elements, each of which is an LED, are disposed on the circuit board 13. The corners of the corner connector 12 are rounded, making the corners of the light ring 1 smoother.

[0045] The first plug-in portion is a plug-in hole 111, and the second plug-in portion is a plug-in protrusion 121. Plug-in protrusion 121 is inserted into plug-in hole 111. A snap-in protrusion 122 is provided on the side of plug-in protrusion 121, and a snap-in groove 112 is provided on the sidewall of plug-in hole 111. After plug-in protrusion 121 and plug-in hole 111 are plugged in and mated, snap-in protrusion 122 and snap-in groove 112 engage, securing the two. Both ends of the corner connector 12 are provided with a plug-in groove 123. The end of the profile 11 is inserted into the plug-in groove 123, and the plug-in protrusion 121 is located within the plug-in groove 123. This arrangement prevents the profile 11 from shaking relative to the corner connector 12.

[0046] Optionally, the light ring 1 further includes a fastener that presses against the circuit board 13 and engages with the profile 11. This fastener includes a linear fastener 14 located in the center of the profile 11. That is, there are four linear fasteners 14, one for each profile 11. The profile 11 is provided with two outward-facing fastener slots 113 along its length, one on each side of the profile 11. Each end of the linear fastener 14 is provided with an inward-extending fastener projection 141 that engages within the fastener slot 113 in the center of the profile 11, securing the center of the circuit board 13 to the profile 11.

[0047] The fasteners also include a corner fastener 15, each of which is provided with two mutually perpendicular fastening protrusions 141 extending inward. The corner fastener 15 is located at the corner connector 12, and the corner fastener 15 blocks the connection between two adjacent circuit boards 13. The two fastening protrusions 141 are respectively engaged with the fastening grooves 113 at the ends of two adjacent profile members 11. An outward-facing fastening groove 113 is also provided on the corner connector 12, and the fastening protrusions 141 of the corner fastener 15 are partially engaged with the corner connector 12. The corner fastener 15 blocks the connection gap between the two adjacent circuit boards 13, making the lamp more beautiful as a whole. The corner fastener 15 is used to fix the ends of the circuit board 13. A circuit board 13 is fixed by a middle straight fastener 14 and two corner fasteners 15 at both ends, so that the circuit board 13 can be effectively fixed. The circuit board 13 is fixed to the profile member 11 by means of snap fasteners, and no screws are required for fixing. The snap-fit ​​assembly method is simple and fast, with high assembly efficiency and low cost.

[0048] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
