Description

[0001] The present application claims priority over the Chinese patent application with application number 202411060084.8 and the designation of the invention ‘Lighting System’, which was filed with the Chinese Patent Office on August 2, 2024, and whose full disclosure is hereby incorporated into the present application by reference. TECHNICAL AREA

[0002] The present invention relates to the technical field of lighting structures, in particular a lighting system. STATE OF THE ART

[0003] Existing lighting systems, such as spotlights, are common lighting devices and are primarily used for overhead lighting in areas such as ceilings, stage performances, museums, hotel lobbies and multi-purpose halls.

[0004] In prior art headlights, the illumination beam is relatively concentrated, allowing certain areas to be illuminated relatively intensely. However, this also limits the illumination angle and thus their range of application. To achieve multi-angle light projection, rotating elements are often arranged between the headlight and the base. An example of this is an energy-saving, brightness-adjustable LED headlight disclosed in Chinese patent application number 202221745279.2, which comprises a lamp housing containing a light-emitting assembly, with an extension tube attached to one end of the lamp housing and a swivel frame attached to the other end.A mounting shaft is rotatably inserted into the swivel frame, to which a mounting bracket is attached that nestles against the inner wall of the swivel frame, with a rotating sleeve screwed onto one end of the mounting shaft, one side of which nestles against the outer wall of the swivel frame, which can solve the positioning task of the lamp housing after the angle adjustment.

[0005] This spotlight cannot rotate 360° or perform more flexible multi-angle rotation. In practical use, any rotation angle that doesn't meet the requirements becomes cumbersome, potentially even necessitating removal of the light from its base for readjustment. Furthermore, subsequent angle adjustments prove extremely difficult due to the elevated mounting position after installation. PRESENTATION OF THE INVENTION

It should be noted that the term “oder” generally includes the meaning of “and / or”, unless explicitly stated otherwise herein.

[0026] In the following description, numerous directional terms are used to clarify the structure and function of the present invention. However, terms such as "front", "back", "left", "right", "outside", "inside", "outwards", "inwards", "above" and "below" are to be understood as convenient expressions and not as restrictive terms.

[0027] The present invention relates to a lighting system 100 comprising a first bracket 1, a rotating element 2, a first drive element 3, a second bracket 5, a second drive element 4, and a lamp 6. The first bracket 1 also serves as the housing of the lighting system, wherein the housing is cylindrical and its base has a light-emitting opening. The first bracket 1 serves to receive the rotating element 2, the first drive element 3, the second bracket 5, the second drive element 4, and the lamp 6. In other embodiments, the housing can also be formed in other shapes.

[0028] The rotating element 2 is located within the first bracket 1 and is rotatably connected to the first bracket 1. The first drive element 3 is connected to the rotating element 2 and can drive the rotating element 2 to rotate.

[0029] The second bracket 5 is located inside the first bracket 1 and is connected to the rotating element 2, allowing it to rotate with the rotating element 2. The second bracket 5 also forms the inner housing of the lighting system. In other embodiments, the second bracket 5 may have different shapes. The second drive element 4 is connected to the rotating element 2 and can cause the second bracket 5 to pivot, and the second bracket 5 can also rotate with the rotating element 2. The light 6 is connected to the second bracket 5 and is located at the lower end of the first bracket 1. The light 6 can pivot with the second bracket 5 and can also rotate with the rotating second bracket 5 and the rotating element 2.

[0030] The first drive element 3 and the second drive element 4 are attached to the rotating element 2 and do not participate in the swiveling of the second bracket 5, which reduces the swiveling weight and the moment of inertia of the swiveling of the second bracket 5 and the light 6, thus reducing the drive load and making the swiveling faster and more accurate and the stopping response faster.

[0031] In the Fig. In the embodiment shown in Figures 1-5, the first bracket 1 has a cylindrical shape extending around a vertical axis and is provided at its upper end with a top cover 11, which is firmly connected to the first bracket 1. The base of the first bracket 1 is a light-emitting opening for deflecting light rays from the luminaire 6. In use, the upper end of the first bracket 1 can be firmly positioned against the ceiling or wall, so that the first bracket 1 forms a secure fit.

[0032] Alternatively, the upper cover 11 is provided with a cable entry opening 12 that avoids the cables connected to the first drive element 3 and the second drive element 4. The cables are routed through the upper cover 11 and then connected to the first drive element 3 and the second drive element 4 on the rotating element 2. These cables are positioned to avoid the light 6 at the lower end of the first bracket 1 as much as possible to prevent cable wear during the rotation of the rotating element 2.

[0033] Furthermore, a toothed ring 7 is provided on the inner wall of the first bracket 1, extending around its axis. This toothed ring 7 is annular and runs in one revolution around the inner wall of the first bracket 1. The rotating element 2 has an annular shape extending around the vertical axis and is provided with several mounting grooves, some of which serve for mounting the first drive element 3 and the second drive element 4. In other embodiments, the first drive element 3 and the second drive element 4 can, of course, also be mounted on the rotating element 2 in other ways.

[0034] Of the several mounting slots, two are defined as the first mounting slot 21 and the second mounting slot 22, respectively. The first mounting slot 21 and the second mounting slot 22 are both open towards the radial outer side of the rotating element 2, with the first mounting slot 21 being located below and communicating with the second mounting slot 22, and the second mounting slot 22 also being open towards the upper end of the rotating element 2.

[0035] The first drive element 3 comprises a first motor 31 and a gear 32 connected to the main shaft of the first motor 31, the first motor 31 being connected to the rotating element 2 and located within a second mounting groove 22. The main shaft of the first motor 31 extends vertically and with its lower end into the first mounting groove 21.

[0036] The axis of gear 32 extends vertically and is located within the first mounting groove 21. Gear 32 is connected to the main shaft of the first motor 31, with part of gear 32 located on the radial outer surface of the rotating element 2 and engaging with a rack 11. When the first motor 31 rotates, it can cause gear 32 to roll along the toothed ring 7, thus driving the rotating element 2 to rotate about an axis extending vertically, thereby rotating the lamp 6 about an axis extending vertically.

[0037] Furthermore, a projection shaft 25, which is a circular cylinder extending in a vertical direction, is provided on the bottom wall of the first mounting groove 21. The gear 32 is rotatably mounted on the projection shaft 25 to increase the torsional stability of the gear 32.

[0038] It is understood that in other embodiments the first motor 31 and the gear 32 may also be attached to the first support 1, while the ring gear 7 is arranged on the radial outside of the rotating element 2 and extends annularly around the vertical axis, with the ring gear 7 and the gear 32 meshing with each other. When the first motor 31 rotates, it rotates the gear 32, which drives the ring gear 7 and the rotating element 2 to rotate.

[0039] Alternatively, the first drive element 3 can also be designed differently, for example such that the first motor 31 is arranged on the upper cover 11 of the first bracket 1 and the two ends of a rotating shaft are connected to the main shaft of the first motor 31 and the rotating element 2 and, when the first motor 31 is rotated, it can also drive the rotating element 2 to rotate.

[0040] The rotating element 2 comprises an annular support 27 and a flange 28. The flange 28 and the annular support 27 are both coaxially arranged ring structures, and the flange 28 is located on the radial outer surface of the annular support 27 and extends along its outer circumference. The first mounting groove 21, the second mounting groove 22, as well as the third mounting groove 23 and fourth mounting groove 24 described below, are all located above the flange 28 and are formed by recesses in the annular support 27. The bottom wall of the second mounting groove 22 extends to the top of the flange 28.

[0041] To facilitate stable rotation of the rotating element 2, a guide element 29 is provided on the underside of the flange 28. This guide element is a projection extending from the edge of the underside of the flange 28. A support ring 14 is provided on the inside of the first bracket 1. This support ring has an annular shape extending around the circumference of the first bracket 1 and rests against the underside of the flange 28 to support the flange 28. Furthermore, a guide groove 15 is provided on the top side of the support ring 14. This groove also has an annular shape extending around the circumference of the support ring 14. The guide element 29 is inserted into the guide groove 15. When the rotating element 1 is rotated, the guide element 29 can move along the guide groove 15.

[0042] The second bracket 5 is also cylindrical, and both its upper and lower ends are open. The second bracket 5 is located inside the ring of the rotating element 2 and is movably connected to the rotating element 2 to accommodate the luminaire 6. The luminaire 6 is located inside the cylinder of the second bracket 5 and near its lower end. The lower end of the second bracket 5 also serves as a light outlet for deflecting light rays.

[0043] Two further mounting slots of the rotary element 2 are a third mounting slot 23 and a fourth mounting slot 24, which serve to mount the second drive element 4. The third mounting slot 23 is located near the first mounting slot 21 and the second mounting slot 22, while the fourth mounting slot 24 and the third mounting slot 23 are arranged centrally symmetrically with respect to the vertical axis of the first bracket 1.

[0044] The second drive element 4 serves to drive the second bracket 5 to pivot about a horizontal axis, i.e., the light fixture 6 is in a pivoting position. Specifically, the second bracket 5 is provided with axle bores 51 that align with the third mounting groove 23 and the fourth mounting groove 24. The second drive element 4 comprises a second motor 41 and a drive shaft, the second motor 41 being located within the third mounting groove 23, with its main shaft forming a horizontal axis, i.e., the main shaft of the second motor 41 can rotate about this horizontal axis. The axis of the drive shaft and the axis of the main shaft of the second motor 41 are arranged coaxially with each other. The third mounting groove 23 and the fourth mounting groove 24 each communicate with the inner ring of the rotating element 2.The main shaft of the second motor 41 extends into one of the axle bores 51 of the second bracket 5 and is firmly connected to the inner wall of this axle bore 51. This means that when the second motor 41 is started, it can rotate the second bracket 5 about its axis via the axle bore 51.

[0045] One end of the drive shaft is located within the other axle bore 51 and is fixedly connected to this axle bore 51, while the other end is located within the fourth mounting groove 24 and is rotatably connected to the fourth mounting groove 24. After the second motor 41 is started, the second bracket 5 can rotate the drive shaft about its axis within the fourth mounting groove 24, thereby pivoting the light 6 about the axis of the drive shaft. In some other embodiments, one end of the drive shaft is rotatably connected to the other axle bore 51, and the other end is fixedly or rotatably connected to the fourth mounting groove 24.

[0046] Furthermore, the drive shaft can be rotatably connected to its corresponding axle bore 51 or the fourth mounting groove 24 via a bearing 42 in order to reduce wear.

[0047] Furthermore, in the Fig. 2 and Fig. In the embodiment shown in Figure 9, two bead rings 52 are provided on the radial outer side of the second bracket 5, arranged symmetrically to the center of the second bracket 5 and opposite the third mounting groove 23 and the fourth mounting groove 24, respectively. The axle bores 51 are formed by recessing the outer surface of the two bead rings 52 into the second bracket 5. The main shaft of the second motor 41 enters the axle bore 51 of one of the bead rings 52 from the rotating element 2 and is fixedly connected to the inner wall of this axle bore 51. One end of the drive shaft is located inside the other bead ring 52 and is fixedly connected to this bead ring 52, while the other end is connected to the bearing 42 inside the fourth mounting groove 24, i.e., rotatably connected to the fourth mounting groove 24.

[0048] Furthermore, the first mounting groove 21 and the third mounting groove 23 are open towards the upper end of the rotating element 2, which facilitates the mounting of the first motor 31 and the second motor 41.

[0049] The upper surfaces of the first motor 31 and the second motor 41 each project beyond the upper end of the rotating element 2. To secure the first motor 31 and the second motor 41, a mounting bracket 26 is provided at the upper end of the rotating element 2. This bracket is connected to the upper end of the rotating element 2 and has two mounting grooves. One of these grooves is positioned on the upper surface of the first motor 31 and secures it, while the other is positioned on the upper surface of the second motor 41 and secures it. These two mounting grooves secure the first motor 31 and the second motor 41, preventing them from dislodging from the first mounting groove 21 and the third mounting groove 23 after starting, and increasing the stability of the first motor 31 and the second motor 41.

[0050] The lighting system 100 further comprises a heat dissipation element 8 and a light-collecting shade 9, wherein the heat dissipation element 8 covers the upper end of the luminaire 6 and is connected to the upper end of the second bracket 5 by screws or otherwise. The heat dissipation element 8 serves to dissipate heat from the luminaire 6.

[0051] The inner diameter of the light-collecting screen 9 tapers from the bottom to the top and is essentially conical. The light-collecting screen 9 is located at the bottom of the luminaire 6 and is connected to the inner wall of the first bracket 1. The light-collecting screen 9 is located at the bottom of the first bracket 1 and serves to focus the light rays of the luminaire 6.

[0052] Furthermore, a locking hook 91 is provided outside the light-collecting screen 9, and a locking ring 13 extending around the circumference of the first bracket 1 is provided on the inner wall. The locking hook 91 of the light-collecting screen 9 can engage in any position of the locking ring 13, which facilitates the attachment of the light-collecting screen 9 to the first bracket 1.

[0053] Preferably, the light-collecting screen 9 is also provided with a cable entry opening for avoiding cables, which extends to the upper end of the light-collecting screen 9 in order to avoid the cables.

[0054] The lighting system 100 further comprises a slip ring 10, which is connected to the lower end of the rotating element 2 and located at the upper end of the light-collecting screen 9, and which is connected to the first drive element 3 and the second drive element 4. External cables can enter the interior from the first bracket 1 and be connected to the slip ring 10 through the cable entry opening of the light-collecting screen 9. The slip ring 10 is then connected to the first drive element 3 and the second drive element 4 to prevent wear on the cables caused by the rotation of the rotating element 2.

[0055] In some embodiments, as in Fig. As shown in Figure 10, a bearing 15 is arranged between the rotating element 2 and the first support 1 for a rotatable connection. In particular, the bearing 15 is arranged within the first support 1 and mounted on the rotating element 2, the rotating element 2 being rotatably connected to the bearing 15. In the Fig. In the embodiment shown in Figures 10-12, an outer support 16 is provided on the inside of the first bracket 1 to support the bearing 15, while the first bracket 1 is provided with an inner support 27 opposite the outer support. The outer support 16 and the inner support 27 are radially oriented and serve to support the bearing 15. In other embodiments, the bearing 15 can be attached to the inner wall of the first bracket 1 in a different manner.

[0056] If no slip ring 10 is installed, the cables must be routed through the cable entry opening 12 in the upper cover 11 and then connected to the first drive element 3 and the second drive element 4. While the rotation of the rotary element 2 allows the cables to avoid the light 6, they can still contact the heat dissipation element 8 or the first bracket 1 due to the rotation of the rotary element 2, causing wear. The installation of a slip ring 10 can effectively reduce cable wear.

[0057] The preferred solution, as in the Fig. As shown in Figures 10-13, a guide groove 115 is provided at the lower end of the upper cover 11, extending in an arc or ring shape around the vertical axis. Several sliding elements 111 are movably mounted within the guide groove 115. Several hooks 112 are connected to each of the sliding elements 111. The cables can be inserted through each of the hooks 112 and then connected to the first drive element 3, the second drive element 4, or other components. During rotation of the rotary element 2, the sliding elements 111 can slide within the guide groove 115, preventing the cables from rotating excessively and thus reducing cable wear.

[0058] Furthermore, in the Fig. In the embodiment shown in Figure 13, an outer mounting ring 113 and an inner mounting ring 114 are also mounted at the lower end of the upper cover 11. The outer mounting ring 113 is located at the edge of the upper cover 11, and the inner mounting ring 114 is located on the radial inner side of the outer mounting ring 113. An outer groove 1141 extending circumferentially is provided on the radial outer side of the inner mounting ring 114, and an inner groove 1131 extending circumferentially is provided on the radial inner side of the outer mounting ring 113. The inner groove 1131 and the outer groove 1141 are joined together to form the guide groove 115 described above, which facilitates the mounting of the sliding elements 111.

[0059] In the Fig.In the embodiment shown in Figure 13, the sliding elements 111 are balls and can also be formed in other shapes in other embodiments, for example as cylinders, as long as they can slide within the guide groove 115. It should be understood that in some embodiments the cables can also be connected directly to the lower end of the sliding elements 111 without hooks 112.

[0060] The preferred embodiments of the present invention have been described in detail above. However, it should be understood that, if necessary, aspects of the embodiments can be modified to provide further embodiments by incorporating aspects, features, and concepts from various patents, applications, and publications.

[0061] Taking into account the detailed description above, these and other modifications to the embodiments are possible. In general, the terms used in the claims should not be considered limited to the specific embodiments disclosed in the description and the claims, but rather should be understood to include all possible embodiments together with the entire scope of equivalence afforded by these claims.

[0062] A person skilled in the art will understand that the individual embodiments described above are concrete examples of how to implement the present invention. In practical application, various modifications in form and detail can be made without deviating from the spirit and scope of the present invention. QUOTES INCLUDED IN THE DESCRIPTION
