[0049] The present application relates to a lighting system 100, which includes a first support 1, a rotating element 2, a first drive element 3, a second support 5, a second drive element 4 and a lighting device 6. The first support 1 is configured to mount the rotating element 2, the first drive element 3, the second support 5, the second drive element 4 and the lighting device 6.

[0050] In the embodiments shown in Figures 1 to 3, the first support comprises an outer casing and a lower retaining frame that are detachably connected to each other. The outer casing and the lower retaining frame are tubular in shape, and an upper end of the lower retaining frame is connected, in a detachable manner, to a lower end of the outer housing. It should be understood that the first support may consist of only the lower retaining frame or the outer housing, and the lower retaining frame or the outer housing may be formed differently, as long as it can mount a toothed ring and support the rotation of the rotating element. The specific shape of the first support is not limited in this application.

[0051] The rotating element 2 is positioned in the first support 1 and is rotationally connected to the first support 1 and can rotate around a vertical axis, which is also a central axis of the first support 1. The first drive element 3 is connected to the rotating element 2 and can drive the rotating element 2 to rotate.

[0052] The second support 5 is positioned in the first support 1 and is connected to the rotating element 2 and can rotate jointly with the rotating element 2. The second support 5 serves as the internal housing of the lighting system 100. In other embodiments, the second support 5 may have other shapes.

[0053] The second drive element 4 is connected to the rotating element 2 and is adjacent to the first drive element 3. It can drive the second support 5 to rotate about a horizontal axis, thus causing the second support 5 to swing. The second support 5 can also rotate together with the rotating element 2. The lighting fixture 6 is connected to the second support 5 and is positioned at one lower end of the first support 1. The lighting fixture 6 can swing together with the second support 5 and rotate together with the second support 5 and the rotating element 2. Both the first and second drive elements are motors.The first drive element causes the rotating element to rotate around the vertical axis through the cooperation of a gear and a toothed ring, and the second drive element is connected to the second support and can directly drive the second support to rotate.

[0054] In other embodiments, the lighting device 6 can be directly connected to the rotating element 2 and rotate together with the rotating element 2 without swaying. In this case, the second support 5 and the second drive element 4 are not required.

[0055] Furthermore, in the present application, the lighting system 100 further comprises a wire guide part 7, which is connected to the rotating element 2 and is provided with a wire guide groove 723. The wire guide groove 723 has a wire inlet 74 located on the vertical axis and a wire outlet 75 open towards the first drive element 3.

[0056] The wire guide portion 7 is connected to the rotating element 2 and can rotate jointly with the rotating element 2. External wires can pass through the wire inlet 74 of the wire guide portion 7 into the wire guide groove 723 and then connect to the first drive element 3 and the second drive element 4 via the wire outlet 75. Since the second drive element 4 is adjacent to the first drive element 3, the second drive element 4 is essentially positioned below the wire outlet 75. When the wire guide section 7 rotates around the vertical axis, the position of the wire inlet 74 remains unchanged, as it is positioned on the vertical axis. During this rotation, the wire guide section 7 and the first drive element 3 rotate together, and their relative positions within the first support 1 remain fixed, preventing the wires from tangling. This ensures a stable connection of the wires to the first drive element 3, thus guaranteeing wire stability and preventing them from tearing.

[0057] In a first embodiment, the wire guide section 7 comprises a wire guide plate and a wire pressure plate 73. The wire guide plate is connected to an upper end of the rotating element 2 and is provided with the wire guide groove 723. The wire guide groove 723 can be pressed into an upper surface of the wire guide plate. The wire outlet 75 is positioned above the first drive element 3, and the wire inlet 74 is positioned on the vertical axis and opens at a vertex of the wire guide plate.

[0058] The wire pressure plate 73 is connected to the upper surface of the wire guide plate and covers the wire guide groove 723, preventing wire movement and improving their stability.

[0059] In another embodiment, the wire guide plate further comprises a retaining plate 71 and a wire guide element 72. The retaining plate 71 is circular, and its center lies on the vertical axis. The retaining plate 71 is positioned at the upper end of the rotating element 2 and is preferably integrally formed with the wire guide element 72.

[0060] The wire guide element 72 is positioned on an upper surface of the support plate 71 and extends from an edge of the retaining plate 71 to the center of the retaining plate 71, i.e., to the vertical axis. Furthermore, the wire guide element 72 has an inner end 721 and an outer end 722. The wire outlet 75 of the wire guide groove 723 is positioned at the outer end 722 of the wire guide element, and the wire inlet 74 is positioned at the inner end 721 of the wire guide element.

[0061] The wire guide groove 723 is provided on an upper surface of the wire guide element 72 and extends from the outer end 722 to the inner end 721 of the wire guide element. In other words, the wire inlet of the wire guide groove 723 is at the center of the retaining plate 71, and the outlet wire 75 is at the edge of the retaining plate 71. The wire outlet 75 of the wire guide groove 723 is at the outer end of the wire guide element and extends towards a lower surface of the support plate 71, and the wire inlet 74 is positioned at the inner end 721 of the wire guide element.

[0062] The rotating element 2 is annular in shape and surrounds the vertical axis and is positioned below the edge of the retaining plate 71.

[0063] Furthermore, the lighting system 100 also includes a support frame 76.

The wire guide hole 761 is positioned above the first drive element 3 and the second drive element 4 and below the wire outlet 75.

[0064] The wire guide plate covers the upper end of the retaining frame 76, with the edge of the wire guide plate positioned above the wire guide hole 761. The wire guide groove 723 extends from the edge of the support plate 71 to the vertical axis, and the wire outlet 75 is positioned above the wire guide hole 761. The wires pass through the wire outlet 75 of the wire guide groove 723, and then through the wire guide hole 761 before extending towards the first drive element 3. The wire guide hole 761 can further stabilize the wiring.

[0065] As a preferred solution, the lighting system 100 further includes a top cover 11 which is connected to an upper end of the first support 1 and is provided with a wire entry hole. The wire entry hole has an internal end opening 114 aligned with the wire entry 74 and an external end opening 115 open to an external space. Wires can enter the wire entry hole from the external end opening 115 and then pass through the internal end opening 114 and the wire entry 74 into the wire guide groove 723.

[0066] In addition, the inner end 721 of the wire guide element extends into the inner end opening 114 on a lower plate 112. Since the wire inlet 74 of the wire guide groove 723 is positioned at the inner end 721 of the wire guide element, the wire inlet 74 is also positioned in the inner end opening 114, thus further stabilizing the wiring.

[0067] Furthermore, the upper cover 11 comprises a lower plate 112, an upper plate 111, and a side wall 113. One upper end of the side wall 113 is connected to the upper plate 111, and one lower end of the side wall 113 is connected to the lower plate 112. The side wall 113, the upper plate 111, and the lower plate 112 form a partition to define a hollow cavity 116. The wire entry hole is part of the cavity 116.

[0068] It should be understood that in other embodiments, the upper cover 11 may be a plate of a certain thickness. The wire entry hole is positioned in the upper cover 11, the external end opening 115 is provided on an external radial side of the upper cover 11, and the internal end opening 114 is positioned on a lower side of the upper cover 11.

[0069] In the embodiment shown in the figures, the lower plate 112 or the side wall 113 is connected to the first support 1 and is provided with the internal end opening 114. The internal end opening 114 is positioned on a lower surface of the lower plate 112 and is connected to the wire inlet 74.

[0070] In a preferred embodiment, the wire guide plate further has several drilled parts 711, which can reduce the weight of the wire guide plate.

[0071] The lighting system 100 further includes a heat dissipation element and a light concentrator element. The heat dissipation element covers one upper end of the lighting device 6 and is connected to one upper end of the second support 5 via bolts or other means, and the heat dissipation element serves to dissipate heat from the lighting device 6.

[0072] The light concentrator has an internal diameter that gradually decreases from its lower end to its upper end, and the light concentrator is approximately conical in shape. The light concentrator is positioned at one lower end of the lighting device 6 and is connected to an internal wall of the first support 1. The light concentrator is positioned at one lower end of the first support 1 and serves to concentrate the light emitted by the lighting device 6.

[0073] In certain embodiments, a bearing is further provided between the rotating element 2 and the first support 1 for rotational connection. Specifically, the bearing is arranged inside the first support and around the rotating element, and the rotating element is rotationally connected to the bearing.

[0074] Optionally, an annular toothed ring is mounted on an internal wall of the external housing and cooperates with a gear mounted on the rotating element to drive the rotating element to rotate.

[0075] As a preferred solution, a support ring is provided on an inner side of the lower retaining frame to support the bearing. An annular groove is provided on an outer radial side of the rotating element. One inner radial side of the bearing is mounted in the annular groove, and one outer radial side of the bearing is supported by the support ring. In other embodiments, the bearing can be fixed to the inner wall of the first support in other ways.
