[0037] In order to illustrate the technical solution of the present invention, a detailed description is given below in conjunction with specific drawings and embodiments.

[0038] Please also read Figures 1 to 3 The embodiment of the present invention provides a rotating downlight, which includes a face ring 10, a guide rail bracket 20, a rotating bracket 30 and a light emitting assembly 40. For the convenience of description, Figure 1The direction in is the standard. The guide rail bracket 20 is roughly annular, such as a circular ring, and is sleeved outside the face ring 10. Part of the guide rail bracket 20 extends into the face ring 10 and forms an annular guide rail inside the face ring 10; the rotating bracket 30 is sleeved inside the face ring 10, and it cooperates with the annular guide rail and can rotate inside the annular guide rail; the light-emitting component 40 is sleeved inside the face ring 10 and is fixedly connected to the bottom of the rotating bracket 30. It can rotate together with the rotating bracket 30, so that the light-emitting component 40 is concentric with the face ring 10, thereby improving the optical quality. When the rotating bracket 30 is installed in the annular guide rail in the face ring 10, it is rotated by the annular guide rail on the guide rail bracket 20 to realize the rotation of the light-emitting component 40, which plays a lighting role in different directions and improves the customer experience.

[0039] In this embodiment, the face ring 10 is roughly cylindrical, and can be formed by connecting multiple sections of cylindrical bodies with different diameters. In addition, the face ring 10 is made of metal material or plastic in one piece, one end of which is closed and the other end has an opening. The rotating bracket 30 and the light-emitting component 40 are inserted into the face ring 10 through the opening of the face ring 10.

[0040] The present embodiment adopts a new rotation method combining the guide rail bracket 20 and the rotating bracket 30. After the rotating bracket 30 is installed in the guide rail bracket 20, it can rotate in the annular guide rail, and the light-emitting component 40 is connected to the bottom of the rotating bracket 30, so that the light-emitting component 40 can rotate together with the rotating bracket 30 to play a lighting role in different directions; since the rotating bracket 30 rotates and slides in the annular guide rail, during the rotation of the rotating bracket 30, the light-emitting component 40 is always concentric with the face ring 10, and no eccentricity occurs; and the method of combining the guide rail bracket 20 with the rotating bracket 30 is convenient for rotation and provides a good user experience.

[0041] Please combine Figure 4 In one embodiment of the present invention, the longitudinal section of the guide rail bracket 20 is L-shaped, and includes a first top portion 201 and a first side portion 202 connected to each other. The first top portion 201 is perpendicular to the first side portion 202. The end of the first side portion 202 away from the first top portion 201 extends inwardly (toward the center direction of the guide rail bracket 20) along its circumferential direction to form a plurality of guide strips 203, and the guide strips 203 are parallel to the first top portion 201. Correspondingly, a plurality of guide holes 11 are opened along its circumferential direction on the face ring 10, and the guide holes 11 correspond to the guide strips 203 one by one and cooperate with each other. The shape of each guide strip 203 matches the shape of the guide hole 11 and is penetrated by the corresponding guide hole 11. In this embodiment, when the guide rail bracket 20 is assembled on the face ring 10, the first top portion 201 and the first side portion 202 are respectively in close contact with the outer surface of the face ring 10, and the plurality of guide strips 203 and the inner wall of the face ring 10 are enclosed to form the above-mentioned annular guide rail. In a specific application, the first top portion 201, the first side portion 202 and the guide bar 203 are integrally formed to simplify the structure and save costs.

[0042] Please combine Figure 3 and Figure 4 In one embodiment of the present invention, the guide rail bracket 20 includes a first guide rail 21 and a second guide rail 22, wherein the first guide rail 21 and the second guide rail 22 are butted against each other to enclose and form a ring, and both the first guide rail 21 and the second guide rail 22 include the first top portion 201, the first side portion 202 and the guide bar 203. In this embodiment, the guide rail bracket 20 is designed as a two-part butt-jointed structure, which not only has good structural strength, but also is convenient for installation and disassembly and maintenance. In a specific application, a bending portion 205 is extended at both ends of the first guide rail 21 and the second guide rail 22, respectively. The bending portion 205 can be formed by bending the two ends of the first guide rail 21 and the second guide rail 22. The bending portion 205 is formed by bending the end of the first top portion 201 upward, and the bending portion 205 is generally L-shaped. The bending portion 205 of the first guide rail 21 and the bending portion 205 of the second guide rail 22 are fixedly connected together by fasteners, so that the rotating bracket 30 does not loosen or deform when rotating. The fasteners include but are not limited to screws. During assembly, the guide bars 203 of the first guide rail 21 and the second guide rail 22 are inserted into the corresponding guide holes 11 of the face ring 10 to position the first guide rail 21 and the second guide rail 22, and then the first guide rail 21 and the second guide rail 22 are fixedly connected together by fasteners, thereby completing the assembly of the guide bracket 20 and the face ring 10.

[0045] In one embodiment of the present invention, the second side portion 301, the first bottom portion 302 and the third side portion 303 are integrally formed to simplify the structure and save costs. Specifically, the rotating bracket 30 is formed by stamping a metal plate, and the metal plate has a certain thickness. Such a design makes it difficult for the rotating bracket 30 to deform once the mold is formed, ensuring that the rotating bracket 30 is smooth when rotating, so that the user has a good operating experience. The thickness of the metal plate can be 1mm to 3mm, such as 1mm, 1.5mm, 2mm, 2.5mm or 3mm, etc., wherein 1.5mm is preferred.

The first limiting protrusion 204 and the second limiting protrusion 304 are both roughly square, the first limiting protrusion 204 is integrally formed with the guide strip 203, and the second limiting protrusion 304 is integrally formed with the first bottom portion 302. In this embodiment, the first limiting protrusion 204 is provided on one of the guide strips 203, and the second limiting protrusion 304 that cooperates with the first limiting protrusion 204 is provided on the rotating bracket 30, so as to prevent the rotating bracket 30 from rotating more than 360 degrees in the annular guide rail, thereby avoiding the risk of breaking the internal wiring of the rotating downlight during rotation.
