Description

Lighting system

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 3, 2024, with application number 2024100103270 and invention name “Lighting System”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the technical field of lighting structures, and in particular to a lighting system. Background Art

[0003] Existing lighting systems such as spotlights are a commonly used lighting device, which is mainly used for high-altitude lighting, such as ceilings, stage performances, museums, hotel lobbies, multi-function halls and other fields.

[0004] The spotlights in the prior art have relatively concentrated lighting beams, which can provide strong illumination to specific parts, but at the same time this also limits their lighting angles, thus affecting their scope of use. In order to achieve multi-angle light projection, people often use a rotating mechanism between the spotlight and the base. For example, the Chinese patent application number 202221745279.2 discloses an energy-saving LED spotlight with adjustable brightness, which includes a lamp tube, a light-emitting component is provided in the lamp tube, an extension tube is fixed to one end of the lamp tube, and a flip frame is fixed to the other end of the lamp tube. A fixed shaft is rotatably plugged into the flip frame, and a fixed frame is fixed to the fixed shaft, which is in contact with the inner wall of the flip frame. A rotating screw sleeve is provided on one end of the fixed shaft, and one side of the rotating screw sleeve is in contact with the outer wall of the flip frame, which can achieve the purpose of positioning the lamp tube after adjusting the angle.

[0005] Since this type of spotlight cannot rotate 360 ​​degrees or more, in actual use, if the rotation angle does not meet the requirements, it will cause operational inconvenience, and even require the lamp to be removed from the base and readjusted. In addition, due to the high installation position, it is very inconvenient to adjust the angle after installation. Summary of the Invention

[0006] The object of the present invention is to provide a lighting system that improves the convenience of angle adjustment and realizes multi-dimensional adjustment, and has a compact overall structure, small size, reduced cost and better use effect.

The first rotating shaft can also rotate about the axis of the first housing, enabling multi-dimensional adjustment of the emitted light. The overall structure integrates the structures of the first and second housings, resulting in a relatively compact and simple structure. The overall design is ingenious and sophisticated, eliminating the need for excessive brackets required to allow the lamp to flip, which results in a bulky lighting system.

[0047] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0048] One embodiment of the present invention relates to a lighting system 100. As shown in Figures 1, 2, 3, and 4, the lighting system 100 can be a spotlight or downlight. The lighting system 100 includes a lamp 1, a first housing 2, a first rotating shaft 3, a first driving member 4, a second housing 5, and a second driving member 6. The bottom of the second housing 5 forms a light outlet. During use, the second housing 5 can be fixedly positioned on a ceiling or wall, forming a fixed base. The lamp 1 can move relative to the second housing 5 to adjust the emitted light. The first housing 2 surrounds the lamp 1. The first rotating shaft 3 is movably connected to the first housing 2, with the axis of the first rotating shaft 3 being perpendicular to the axis of the first housing 2. The first rotating shaft 3 has an internally threaded hole 30. The first driving member 4 includes a first power body 41 fixed to the lamp 1 and a screw 42 connected to the first power body 41. The screw 42 extends through the internally threaded hole 30 and is threadably engaged with the internally threaded hole 30. When the first power body 41 drives the lead screw 42 to rotate, the lead screw 42 causes the first rotating shaft 3 to flip about its axis and moves radially along the first housing 2, causing the lamp 1 to flip relative to the axis of the first housing 2. The second housing 5 is mounted outside the first housing 2 and is rotatably connected to the first housing 2. The second driving member 6 includes a second power body 61 fixed to the first housing 2 and a transmission member 62 connected to the second power body 61. The second power body 61 drives the transmission member 62 to rotate the first housing 2, the lamp 1, and the first driving member 4 along the axis of the second housing 5.

[0049] In other embodiments, the first driving member may include a linear motor. The main shaft of the linear motor may be directly or indirectly fixed to the first rotating shaft member and perpendicular to the axis of the first rotating shaft member. The linear motion of the main shaft of the linear motor drives the first rotating shaft member to rotate about its axis and move the first rotating shaft member in a radial direction of the first housing.

[0050] In this embodiment, the axes of the first housing 2 and the second housing 5 are coaxially arranged. The axis direction of the first housing 2 and the second housing 5 is the longitudinal direction, and the axis direction of the first rotating shaft 3 is the transverse direction.

[0051] From the above, it is not difficult to find that the second housing 5 is fixed to a wall or other place, and the second housing 5 is positioned as a fixed seat. The first housing 2 is rotatably arranged in the second housing 5. The second power body 61 drives the transmission member 62. The transmission member 62 drives the first housing 2 to drive the lamp 1 to rotate around the axis of the first housing 2 because the second housing 5 is fixed. The first rotating shaft 3 is also set on the first housing 2, and the axis of the first rotating shaft 3 is perpendicular to the axis of the first housing 2. The first power body 41 is fixed to the lamp 1. The first power body 41 drives the screw to rotate. The screw cooperates with the first rotating shaft 3 to make the first rotating shaft 3 flip and move radially. The first rotating shaft 3 drives the lamp 1 to flip as well, thereby changing the angle of the emitted light of the lamp 1. At the same time, it can rotate around the axis of the first housing 2, so as to achieve multi-dimensional adjustment of the emitted light. The overall structure integrates the structures of the first shell 2 and the second shell 5, and the structure is relatively compact and simple. The overall design is smart and exquisite. Unlike the prior art, there is no need to set too many brackets to make the lamp 1 flip over, which causes the lighting system 100 to be structurally auxiliary and larger in size.

[0052] The implementation details of this embodiment are described in detail below. The following content is only for ease of understanding and is not necessary for implementing this solution.

[0053] As shown in Figures 1, 2, 3, and 4, a fixing bracket 7 is fixed to the second housing 5 for positioning, and the fixing bracket 7 is used to secure the second housing 5 to the ceiling or wall. A spotlight 8 corresponding to the lamp 1 is also mounted within the second housing 5. The lamp 1 is rotatably connected to the first housing 2 via a connecting shaft 93. The axis of the connecting shaft 93 is perpendicular to the axis of the first housing 2, and the axis direction of the connecting shaft 93 is the same as the axis direction of the first transmission shaft. When the lamp 1 is flipped, the lamp 1 rotates about the connecting shaft 93, which causes the angle between the axis of the lamp 1 and the axis of the first housing 2 to change.

[0054] Furthermore, as shown in Figures 1, 2, 3, and 4, the first housing 2 is provided with a pair of radially extending limiting grooves 21 spaced apart from each other along the circumference of the first housing 2. The first rotating shaft 3 has its ends disposed in the pair of limiting grooves 21, respectively. The first rotating shaft 3 is slidably disposed along the extending direction of the limiting grooves 21 and is rotatably positioned within the limiting grooves 21.

[0055] In addition, as shown in Figures 1, 2, 3 and 4, in order to limit the flip angle range of the lamp 1, the limiting groove 21 has a limiting block (shown in the figure) for limiting the first rotating shaft 3. When the first rotating shaft 3 slides to a preset position, it abuts against the limiting block.

[0056] Furthermore, as shown in FIG1 , FIG2 , FIG3 and FIG4 , the lamp 1 includes: a lamp body 11 and a heat sink 12 fixed to the lamp body 11 , and the first driving member 4 is fixed to the heat sink 12 .

[0057] Furthermore, as shown in Figures 1, 2, 3, and 4, the heat sink 12 covers the side of the lamp body 11 facing away from the second housing 5. In other words, the heat sink 12 is located on the top of the lamp body 11, thereby covering a larger area of ​​the lamp body 11 and achieving better heat dissipation. A groove 120 is defined on the sidewall of the heat sink 12, and the first power body 41 is disposed in the groove 120, making the overall structure more compact and the lighting system 100 smaller in size.

[0058] Furthermore, as shown in Figures 1, 2, 3, and 4, the second power unit 61 is mounted on the top of the first housing 2. A relief groove 121 is also defined on the peripheral sidewall of the heat sink 12 to accommodate the second power unit 61. The relief groove 121 extends through the heat sink 12 toward the top of the first housing 2. This makes the overall structure more compact and the lighting system 100 smaller in size.

[0059] In addition, as shown in FIG. 2 , FIG. 3 and FIG. 4 , the transmission member 62 is engaged and connected with the inner wall of the second housing 5 .

[0060] Furthermore, as shown in Figures 1, 2, 3, and 4, the inner wall surface of the second housing 5 is a meshing surface 50. The transmission member 62 is a meshing wheel extending along the axis of the first housing 2. The meshing wheel is fixedly connected to the main shaft of the second power body 61. The first housing 2 has a notch 22 for placing the meshing wheel, and the notch 22 has a convex shaft 23 for inserting the meshing wheel. The meshing wheel is rotatably mounted on the convex shaft 23. The second housing 5 is fixedly positioned. When the meshing wheel rotates, it engages with the meshing surface. The second housing 5 where the meshing surface is located is fixed, so that the first housing 2 is driven to rotate about its axis. The axis of the connecting shaft 93 is perpendicular to the axis of the second housing 5. The connecting shaft 93 connects the first housing 2 and the lamp 1, so that the lamp 1 can be driven by the first housing 2 to rotate about the axis of the second housing 5.

[0061] In addition, as shown in Figures 2 and 3, to allow the first housing 2 to rotate smoothly within the second housing 5, a universal ball 91, i.e., a 360° rotatable ball, is embedded in the outer wall of the first housing 2. An axially circumferential track is provided on the inner wall of the second housing 5. When the first housing 2 rotates within the second housing 5, the universal ball 91 rolls along the track. A spring 92 is provided in the groove containing the universal ball 91, with its two ends respectively abutting against the universal ball 91 and the bottom of the groove (i.e., the second housing 5). In other embodiments, the positions of the universal ball 91 and the track can be switched.

[0062] Furthermore, as shown in Figures 2 and 3, the lamp body 11 also includes a main body 111 and a lampshade 112 fixed to the main body 111. The heat sink 12 is fixed to the lampshade 112 and the main body 111, and covers the side of the main body 111 facing away from the second housing 5. The lampshade 112 is at least partially inserted into the first housing 2. The connecting shaft 93 connects the first housing 2 and the lampshade 112, and the lampshade 112 is rotatably connected to the connecting shaft 93.

[0063] In addition, as shown in FIG. 2 and FIG. 3 , a condenser 8 corresponding to the lamp 1 is also provided in the second housing 5 .

[0064] Furthermore, as shown in FIG1 , FIG2 , FIG3 and FIG4 , the top of the first housing 2 has an avoidance position 24 for avoiding the lamp 1 . When the lamp 1 is flipped to a certain angle, part of the lamp 1 is located in the avoidance position 24 .

[0065] Specifically, as shown in Figures 1 and 2, which are the extreme positions of the lamp 1 for flipping, if the lamp 1 needs to be upright, the first power body 41 is controlled to rotate so that the screw 42 can pass through the internal threaded hole 30 more. The first shell 2 is fixed and positioned by the second shell 5 and cannot be flipped. The first rotating shaft 3 flips outward and slides outward along the limiting groove 21. The first rotating shaft 3 slides outward along the limiting groove 21, that is, slides toward the axis away from the first shell 2, until the rectangular block in the middle of the first rotating shaft 3 flips to a horizontal position, that is, the axis of the internal threaded hole 30 is vertical, and the lamp 1 is also vertical.

[0066] While preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.

[0067] These and other changes can be made to the embodiments in light of the above detailed description.In general, in the claims, the terms used should not be construed as limited to the specific embodiments disclosed in the specification and claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which these claims are entitled.
