[0066] This application relates to a lighting system 100, which comprises a first support 1, a rotating element 2, a first drive element 3, a second support 5, a second drive device 4, and a luminaire 6. The first support 1 also serves as the external housing for the lighting system. This external housing is tubular in shape and has a light exit opening at its base. The first support 1 houses the rotating element 2, the first drive element 3, the second support 5, the second drive element 4, and the luminaire 6. In other embodiments, this external housing can be configured in other shapes.

[0067] The rotating element 2 is positioned in the first support 1 and is connected, in rotation, to 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.

[0068] The second support 5 is positioned within the first support 1 and is connected to the rotating element 2 and can rotate in conjunction with the rotating element 2. The second support 5 serves as the internal housing for the lighting system. In other embodiments, the second support 5 may have other shapes. The second drive element 4 is connected to the rotating element 2 and can cause the second support 5 to oscillate, and the second support 5 can rotate in conjunction with the rotating element 2. The luminaire 6 is connected to the second support 5 and is positioned at one lower end of the first support 1. The luminaire 6 can oscillate in conjunction with the first support 1. with the second support 5 and rotate jointly with the second support 5 and the rotating element 2.

[0069] The first drive element 3 and the second drive element 4 are fixed to the rotating element 2 and do not oscillate with the second support 5. This reduces the weight of the components involved in the oscillating motion, thereby decreasing the moment of inertia of the second support 5 and the luminaire 6 during their oscillating motion. For this reason, the drive load is reduced, faster and more precise oscillating movements are obtained, and a faster stopping response can be achieved.

[0070] In the embodiment shown in Figures 1 to 5, the first support 1 is tubular in shape, surrounding a vertical axis. A top cover 11 is provided at the top of the first support 1 and is fixedly attached to it. A light outlet is provided at the bottom of the first support 1, allowing light from the luminaire 6 to pass through it. In use, one upper end of the first support 1 can be fixed to a ceiling or wall, allowing the first support 1 to serve as a fixed base.

[0071] In one embodiment, the upper cover 11 is provided with a wire passage hole 12, which allows the wires connected to the first drive element 3 and the second drive element 4 to pass through it. The wires pass through the upper cover 11 and are connected to the first drive element 3 and the second drive element 4 on the rotating element 2. The wires are arranged to avoid, as far as possible, the luminaire 6 at the lower end of the first support 1, preventing wear on the wires during the rotation of the rotating element 2.

[0072] In addition, a toothed ring 7 is provided on an internal wall of the first support 1 and surrounds an axis of the first support 1. The toothed ring 7 has a closed annular shape and extends circumferentially from the inner wall of the first support 1. The rotating element 2 is also annular in shape, surrounds the vertical axis, and is provided with several mounting grooves. Some of the plurality of mounting grooves are used to mount the first drive element 3 and the second drive element 4. Alternatively, in other embodiments, the first drive element 3 and the second drive element 4 can be mounted on the rotating element 2 in other ways.

[0073] Two of the plurality of mounting grooves are defined as a first mounting groove 21 and a second mounting groove 22. Both the first mounting groove 21 and the second mounting groove 22 are open on an external radial side of the rotating element 2. The first mounting groove 21 is located below the second mounting groove 22 and is in communication with the second mounting groove 22 and the second mounting groove 22 is also open at an upper end of the rotating element 2.

[0074] The first drive element 3 comprises a first motor 31 and a gear 32 connected to a main shaft of the first motor 31. The first motor 31 is connected to the rotating element 2 and is located in the second mounting groove 22. The main shaft of the first motor 31 extends in a vertical direction, and a lower end of the main shaft of the first motor 31 extends into the first mounting groove 21.

[0075] An axis of the gear 32 extends in the vertical direction and the gear 32 is located in the first mounting groove 21. The gear 32 is connected to the main shaft of the first motor 31. A portion of the gear 32 is located at the outer radial side of the rotating element 2 and meshes with the toothed ring 7. When the first motor 31 rotates, it drives the gear 32 to roll along the toothed ring 7, thereby causing the rotating element 2 to rotate about an axis extending in the vertical direction, which further drives the luminaire 6 to rotate about the axis extending in the vertical direction.

[0076] In addition, a projecting shaft 25 is provided on a lower wall of the first mounting groove 21. The projecting shaft 25 is a cylinder extending in the vertical direction. The gear 32 is arranged, in a rotatable manner, around the projecting shaft 25 to improve the rotational stability of the gear 32.

[0077] It should be understood that in other embodiments, the first motor 31 and the gear 32 can be fixed to the first support 1, and the toothed ring 7 is arranged on the outer radial side of the rotating element 2 and extends along the vertical axis to form an annular shape. The toothed ring 7 meshes with the gear 32. When the first motor 31 rotates, it drives the gear 32 to rotate, and the gear 32 drives the toothed ring 7 and the rotating element 2 to rotate.

[0078] In one embodiment, the first drive element 3 can be configured in other ways. For example, the first motor 31 is arranged on the upper cover 11 of the first support 1. The two ends of a rotating shaft are connected to the main shaft of the first motor 31 and to the rotating element 2, respectively. When the first motor 31 rotates, it can also drive the rotating element 2 to rotate.

[0079] The rotating element 2 comprises an annular support body 27 and a flange 28. The flange 28 and the annular support body 27 are both annular in shape and are arranged coaxially. The flange 28 is positioned on an external radial surface of the annular support body 27 and extends along an external circumference of the annular support body 27. The first mounting groove 21, the second mounting groove 22, as well as a third mounting groove 23 and a fourth The mounting groove 24 described below are all positioned above the flange 28 and are recessed into the annular support body 27. A lower wall of the second mounting groove 22 extends towards an upper surface of the flange 28.

[0080] In order to facilitate the stable rotation of the rotating element 2, a guide element 29 is further provided on a lower surface of the flange 28. The guide element 29 is a projection, which is positioned at the level of an edge of the lower surface of the flange 28 and protrudes from the lower surface. A support ring 14 is provided on an inner side of the first support 1. The support ring 14 is annular in shape and extends along a circumference of the first support 1, abutting against the lower surface of the flange 28 to provide support for the flange 28. Furthermore, a guide slot 15 is provided on an upper surface of the support ring 14, which is also annular in shape and extends along a circumferential direction of the support ring 14. The guide element 29 is inserted into the guide slot 15, and when the rotating element 2 rotates, the guide element 29 moves along the guide slot 15.

[0081] The second support 5 is also tubular in shape and has openings at both its base and its top. The second support 5 is arranged in the annular shape of the rotating element 2 and is movably connected to the rotating element 2. The luminaire 6 is housed in the second support 5. The luminaire 6 is positioned within the tubular shape of the second support 5 and is near one lower end of the second support 5, and the lower end of the second support 5 also has a light exit opening to allow light to pass through it.

[0082] Two others of the plurality of mounting grooves of the rotating element 2 are a third mounting groove 23 and a fourth mounting groove 24, which are used to mount the second drive element 4. The third mounting groove 23 is adjacent to the first mounting groove 21 and the second mounting groove 22 and the fourth mounting groove 24 and the third mounting groove 23 are arranged in central symmetry with respect to the vertical axis of the first support 1.

[0083] The second drive element 4 is configured to drive the second bracket 5 to oscillate about a horizontal axis, causing the luminaire 6 to oscillate. Specifically, the second bracket 5 is provided with shaft holes 51 aligned respectively with the third mounting groove 23 and the fourth mounting groove 24. The second drive element 4 comprises a second motor 41 and a connecting shaft. The second motor 41 is positioned in the third mounting groove 23, and a main shaft of the second motor 41 is along a horizontal axis. This means that the main shaft of the second motor 41 can rotate about this horizontal axis. One axis of the connecting shaft is coaxial with the axis of the main shaft of the second motor 41. The third mounting groove 23 and the fourth mounting groove 24 communicate with an inner side of the annular shape of the rotating element 2, and the main shaft of the second motor 41 extends into one of the shaft holes 51 of the second support 5 and is fixedly connected to an inner wall of this shaft hole 51. That is, when the second motor 41 is activated, it can drive the second support 5 to rotate about the horizontal axis through the shaft hole 51.

[0084] One end of the connecting shaft is positioned in the other of the shaft holes 51 and is fixedly connected to that shaft hole 51, and the other end of the connecting shaft is positioned in the fourth mounting groove 24 and is rotationally connected to the fourth mounting groove 24. When the second motor 41 is activated, the second support 5 can cause the connecting shaft to rotate about the axis of the connecting shaft in the fourth mounting groove 24, thus causing the luminaire 6 to oscillate about the axis of the connecting shaft. In other embodiments, one end of the connecting shaft is rotationally connected to the other of the shaft holes 51, and the other end of the connecting shaft is either fixedly connected or rotationally connected to the fourth mounting groove 24.

[0085] In addition, the connecting shaft can be connected, in rotation, to the other of the shaft holes 51 or to the fourth mounting groove 24 by means of a bearing 42 to reduce wear.

[0086] Furthermore, in the embodiment shown in Figures 2 and 9, two protruding rings 52 are provided on an external radial side of the second support 5. These two protruding rings 52 are arranged symmetrically with respect to a center of the second support 5 and are respectively aligned with the third mounting groove 23 and the fourth mounting groove 24. The shaft holes 51 are respectively recessed with respect to the external surfaces of the two protruding rings 52 in the second support 5. The main shaft of the second motor 41 extends from the rotating element 2 in the shaft hole 51 over one of the protruding rings 52 and is fixedly connected to the inner wall of this shaft hole 51.One end of the connecting shaft is positioned in the other of the protruding rings 52 and is fixedly connected to this protruding ring 52 and the other end of the connecting shaft is connected to the bearing 42 in the fourth mounting groove 24, so as to be connected, in rotation, to the fourth mounting groove 24.

[0087] In addition, the first mounting groove 21 and the third mounting groove 23 are open at the upper end of the rotating element 2, facilitating the mounting of the first motor 31 and the second motor 41.

[0088] The upper parts of the first motor 31 and the second motor 41 extend above an upper end of the rotating element 2. In order to fix the first motor 31 and the second motor 41, a fixing support 26 is provided at the upper end of the rotating element 2. The fixing support 26 is connected to the upper end of the rotating element 2 and is provided with two fixing grooves.One of the two mounting grooves houses an upper part of the first motor 31 to fix the first motor 31, and another of the two mounting grooves houses an upper part of the second motor 41 to fix the second motor 4L. By fixing the first motor 31 and the second motor 41 with the two mounting grooves, the first motor 31 and the second motor 41 cannot disengage from the first mounting groove 21 and the third mounting groove 23 after they have been activated, improving the stability of the first motor 31 and the second motor 4L.

[0089] The lighting system 100 further includes a heat dissipation element 8 and a light concentrator element 9. The heat dissipation element 8 covers an upper end of the luminaire 6 and is connected to an upper end of the second support 5, via bolts or other means, and the heat dissipation element 8 functions to dissipate heat from the luminaire 6.

[0090] The light concentrating element 9 has an internal diameter that gradually decreases from its lower end to its upper end, approximately resembling a conical shape. The light concentrating element 9 is located at the lower end of the luminaire 6 and is connected to the inner wall of the first support 1. The light concentrating element 9 is located at the lower end of the first support 1 and functions to concentrate the light emitted by the luminaire 6.

[0091] In addition, carabiners 91 are provided on an external side of the light concentrating element 9 and the internal wall of the first support 1 is provided with a retaining ring 13 extending in a circumferential direction from the first support 1. The carabiners 91 of the light concentrating element 9 can be engaged in any position on the retaining ring 13, facilitating the attachment of the light concentrating element 9 to the first support 1.

[0092] Preferably, the light concentrating element 9 is also provided with a wire passage hole to accommodate wires. This wire passage hole extends towards the upper end of the light concentrating element 9, allowing the passage of wires.

[0093] The lighting system 100 further includes a slip ring 10 which is connected to the lower end of the rotating element 2 and is positioned at one upper end of the light concentrator element 9. The slip ring 10 is connected to the first drive element 3 and the second drive element 4. The external wires can enter the first support 1, pass through the wire passage hole of the light concentrator element 9 and are connected to the slip ring 10, and the slip ring 10 is connected to the first drive element 3 and the second drive element 4, preventing wear on the wires due to the rotation of the rotating element 2.

[0094] In certain embodiments, as shown in [Fig. 10], a bearing 18 is further provided between the rotating element 2 and the first support 1 for the rotary connection. Specifically, the bearing 18 is arranged inside the first support 1 and around the rotating element 2, and the rotating element 2 is rotationally connected to the bearing 18. In the embodiments shown in Figures 10 to 12, the inner side of the first support 1 is provided with an external support portion 16 to support the bearing 18, and the first support 1 has an internal support portion 17 aligned with the external support portion 16. The external support portion 16 and the internal support portion 17 are radially aligned to support the bearing 18. In other embodiments, the bearing 18 can be fixed to the inner wall of the first support 1 in other ways.

[0095] Without the slip ring 10, the wires must pass through the wire passage hole 12 on the upper cover 11 before connecting to the first drive element 3 and the second drive element 4. When the rotating element 2 rotates, although the wires can avoid the light fixture 6, they can still come into contact with the heat dissipation element 8 or the first support 1 due to the rotation of the rotating element 2, causing wear on the wires. Providing the slip ring 10 effectively reduces wire wear.

[0096] As a preferred solution, as shown in Figures 10 to 13, a lower end of the upper cover 11 is provided with a guide groove 115 extending around the vertical axis to form an arc or annular shape. Several sliders 111 are movably mounted in the guide groove 115, and several hooks 112 are respectively connected to the plurality of sliders 111. The wires can be threaded through the plurality of hooks 112 before connection to the first drive element 3 and the second drive element 4 or to other components. When the rotating element 2 rotates, several sliders 111 can slide in the guide groove 115, preventing significant rotation of the wires along with the rotating element 2, thus reducing wire wear.

[0097] Furthermore, in the embodiment shown in [Fig. 13], an external mounting ring 113 and an internal mounting ring 114 are mounted at the lower end of the upper cover 11. The external mounting ring 113 is positioned at an edge of the upper cover 11, and the internal mounting ring 114 is positioned at an internal radial side of the external mounting ring 113. An external groove 1141 extending circumferentially is provided on an external radial side of the internal mounting ring 114, and an internal groove 1131 extending circumferentially is provided on the internal radial side of the external mounting ring 113. The internal groove 1131 and the external groove 1141 are combined to form the guide groove 115 mentioned above, facilitating the mounting of the sliders 111.

[0098] In the embodiment shown in [Fig. 13], the sliders 111 are balls. Alternatively, in other embodiments, the sliders 111 may be shaped differently, such as a cylindrical shape, as long as they can slide in the guide groove 115. It should be understood that in some embodiments, the wires can be directly connected to the lower ends of the sliders 111 without the need for the hooks 112.
