[0046] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0047] An embodiment of the present invention relates to a lighting system 100. Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the lighting system 100 can be a spotlight or a downlight, and 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 is a light outlet, and the second housing 5 can be fixedly positioned on a ceiling or a wall when in use, so that the second housing 5 forms a fixed seat, and the lamp 1 can move relative to the second housing 5 to adjust the emitted light. The first housing 2 surrounds the outside of the lamp 1, and the first rotating shaft 3 is movably connected to 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 rotating shaft 3 has an internal threaded hole 30, and the first driving member 4 includes a first power body 41 fixed to the lamp 1 and a lead screw 42 connected to the first power body 41, and the lead screw 42 passes through the internal threaded hole 30, and the lead screw 42 is threadedly matched with the internal threaded hole 30. When the first power body 41 drives the lead screw 42 to rotate, the lead screw 42 drives the first rotating shaft 3 to flip around its axis, and drives the first rotating shaft 3 to move along the radial direction of the first housing 2, so that the lamp 1 flips relative to the axis of the first housing 2. The second housing 5 is sleeved 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 drive the first housing 2, the lamp 1 and the first driving member 4 to rotate along the axis of the second housing 5.

[0048] In other embodiments, the first driving member may include a linear motor, and the main shaft of the linear motor may be directly or indirectly fixed to the first rotating shaft member and is perpendicular to the axis of the first rotating shaft member. The main shaft of the linear motor drives the first rotating shaft member to flip around its axis direction and drives the first rotating shaft member to move along the radial direction of the first housing through linear motion.

[0049] 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.

[0050] It is not difficult to find from the above content that the second housing 5 is fixed to a wall or other place, the second housing 5 is positioned as a fixed seat, the first housing 2 is rotatably arranged in the second housing 5, and the transmission member 62 is driven by the second power body 61. 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 member 3 is also arranged on the first housing 2, and the axis of the first rotating shaft member 3 is perpendicular to the axis of the first housing 2. The first power body 41 is fixed to the lamp 1, and the first power body 41 drives the screw rod to rotate. The screw rod cooperates with the first rotating shaft member 3 to make the first rotating shaft member 3 flip and move radially. The first rotating shaft member 3 drives the lamp 1 to flip, 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 are no too many brackets set to make the lamp 1 flip over, which causes the lighting system 100 to be structurally auxiliary and larger in size.

[0051] The implementation details of this embodiment are described in detail below. The following content is only provided for easy understanding of the implementation details and is not necessary for implementing this solution.

[0052] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, a fixing frame 7 for positioning is fixed on the second housing 5, and the second housing 5 is fixed to the ceiling or the wall through the fixing frame 7. A condenser 8 corresponding to the lamp 1 is also sleeved in the second housing 5. The lamp 1 is rotatably connected to the first housing 2 through a connecting shaft 93, and 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 rotating shaft. When the lamp 1 is turned over, the lamp 1 rotates around the connecting shaft 93, that is, the angle between the axis of the lamp 1 and the axis of the first housing 2 is changed.

[0053] Furthermore, if Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the first housing 2 is provided with a pair of limiting grooves 21 which are relatively spaced apart along the circumferential direction of the first housing 2, and the limiting grooves 21 extend radially. The two ends of the first rotating shaft 3 are respectively arranged in the pair of limiting grooves 21, and the first rotating shaft 3 can be slidably arranged along the extension direction of the limiting grooves 21 and can be rotatably located in the limiting grooves 21.

[0054] In addition, if Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, 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, and the first rotating shaft 3 abuts against the limiting block when sliding to a preset position.

[0055] Furthermore, if Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the lamp 1 comprises: 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 .

[0056] Furthermore, if Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the heat sink 12 covers the side of the lamp body 11 away from the second housing 5, that is, the heat sink 12 is 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 provided on the peripheral side wall of the heat sink 12, and the first power body 41 is arranged in the groove 120, so that the overall structure is more compact and the lighting system 100 is smaller in size.

[0057] Furthermore, if Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the second power body 61 is installed on the top of the first housing 2. A shunting groove 121 for accommodating the second power body 61 is also provided on the peripheral side wall of the heat sink 12, and the shunting groove 121 extends toward the top of the first housing 2 and penetrates the heat sink 12. This makes the overall structure more compact and the lighting system 100 smaller in size.

[0058] In addition, if Figure 2 , Figure 3 as well as Figure 4 As shown, the transmission member 62 is meshed and connected with the inner wall of the second housing 5 .

[0059] Furthermore, if Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, 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 axial direction of the first housing 2, and 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, and the meshing wheel is rotatably sleeved on the convex shaft 23. The second housing 5 is fixedly positioned, and the meshing wheel cooperates with the meshing surface when rotating. The second housing 5 where the meshing surface is located is fixed, so that the first housing 2 is driven to rotate around its axial direction. 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 around the axial direction of the second housing 5.

[0060] In addition, if Figure 2 , Figure 3 As shown, in order to allow the first housing 2 to rotate smoothly in 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, and an axially surrounding track is provided on the inner wall of the second housing 5. When the first housing 2 rotates in the second housing 5, the universal ball 91 rolls along the track. A spring 92 is provided in the groove where the universal ball 91 is placed, and the two ends of the spring 92 are respectively 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.

[0061] Furthermore, if Figure 2 , Figure 3 As shown, the lamp body 11 further 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 away from the second housing 5. The lampshade 112 is at least partially inserted into the first housing 2, and 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.

[0062] In addition, if Figure 2 , Figure 3 As shown, a condenser 8 corresponding to the lamp 1 is also sleeved in the second housing 5 .

[0063] Furthermore, if Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, 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 .

[0064] Specifically, Figure 1 and Figure 2The middle is the extreme position of the lamp 1 for flipping. If the lamp 1 needs to be vertical, the first power body 41 is controlled to rotate to allow the screw 42 to penetrate the internal threaded hole 30 more. The first shell 2 is fixed in place 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, it slides in the axial direction 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.

[0065] Preferred embodiments of the present invention have been described in detail above, but 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.
