[0028] The present invention provides a rotatable LED downlight, such as Figures 1 to 6 As shown, it includes: a radiator 1, the radiator 1 is used to dissipate heat for the light source, a light source 2 is fixedly installed in the middle of the bottom end of the radiator 1, the light source 2 is used to emit light, a lens 3 is installed at the bottom end of the radiator 1 at the bottom end of the light source 2, the lens 3 is used for the flow of light and to protect the light source 2, an inner ring 4 is installed at the bottom end of the radiator 1 at the outside of the lens 3, the inner ring 4 is used to fix the light source 2 and the lens 3, a swing ring 5 is installed at the bottom end of the radiator 1 at the outside of the inner ring 4, a rotating ring 6 is rotatably connected to the outside of the swing ring 5, a protective cover 7 is clamped and installed at the bottom end of the inner wall of the rotating ring 6, and a front ring 8 is clamped and installed on the outside of the rotating ring 6;

[0029] A rotating rod 9 is rotatably connected inside the rotating ring 6, and the outer side of the rotating rod 9 is in contact with the bottom end of the swinging ring 5. A clamping assembly 10 is installed on the outer side of the swinging ring 5. A guide groove 11 is opened inside the rotating ring 6 at a position corresponding to one end of the clamping assembly 10. Positioning holes 12 are equidistantly opened inside the guide groove 11. Scale bars 13 are equidistantly engraved on the outer side of the rotating ring 6 at a position corresponding to the top end of the guide groove 11.

[0030] like Figure 1 and Figure 2As shown, the front ring 8 is convex in shape, and circular holes are equidistantly provided at the top of the front ring 8 to facilitate connection with the ceiling, thereby changing the difficulty of connection with the ceiling. The protective cover 7 is composed of a conical cover and a connecting strip, and the top diameter of the conical cover is smaller than the bottom diameter, which is convenient for guiding the light source, thereby increasing the irradiation range.

[0031] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping assembly 10 includes a T-shaped column 1001 fixedly mounted on the outside of the swing ring 5, one end face of the T-shaped column 1001 is symmetrically slidably connected with a semi-cylinder 1002, the opposite surfaces of the two semi-cylinders 1002 are fixedly mounted with concave blocks 1003, the inside of the concave block 1003 is rotatably connected with a rotating bar 1004, and a moving block 1005 is rotatably connected between the two rotating bars 1004, which can facilitate the relative movement of the two semi-cylinders 1002 and change the difficulty of the relative movement of the two semi-cylinders 1002, thereby separating the semi-cylinders 1002 from the rotating ring 6.

[0032] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rectangular rod 1006 is embedded and installed on one end face of the T-shaped column 1001, and a moving block 1005 is slidably connected to the outside of the rectangular rod 1006. Rectangular holes are symmetrically opened on both end faces of the rectangular rod 1006 at equal distances. A circular ring 1007 is welded on one end of the moving block 1005. A plastic strip 1008 is fixedly installed at the top of the moving block 1005 at the inner position of the circular ring 1007. A connecting rope 1009 that passes through the circular ring 1007 is fixedly connected to one end of the plastic strip 1008. A rotating sleeve 1010 is fixedly installed on one end of the connecting rope 1009. When the rotating sleeve 1010 rotates, the plastic strip 1008 is driven to deflect through the connecting rope 1009. At this time, the plastic strip 1008 is separated from 1006 along the rectangular hole, thereby facilitating the release of the moving block 1005, thereby enabling the moving block 1005 to be displaced.

[0033] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the rotating sleeve 1010 is rotatably connected to the top of the ring 1007, and a positioning groove is provided at the top of the ring 1007. The bottom end of the rotating sleeve 1010 is rotatably connected to the inside of the positioning groove, which is convenient for the rotation of the rotating sleeve 1010 and changes the difficulty of rotating the rotating sleeve 1010. The shape of the plastic strip 1008 is T-shaped, and the plastic strip 1008 is provided with a rounded corner at the edge of one end surface corresponding to the rectangular rod 1006, which is convenient for the connection between the plastic strip 1008 and the rectangular rod 1006 and changes the difficulty of connecting the plastic strip 1008 and the rectangular rod 1006. One end surface of the T-shaped column 1001 is symmetrically provided with a sliding groove, and one end surface of the semi-cylinder 1002 is located at the inner position of the sliding groove and a slider is fixedly installed, which is convenient for the movement of the semi-cylinder 1002 and can limit the semi-cylinder 1002 after movement to prevent the semi-cylinder 1002 from offset.

[0034] Working principle: During actual use of the device, the radiator 1, light source 2, lens 3, inner ring 4, swing ring 5, rotating ring 6, protective cover 7 and front ring 8 are sequentially combined to form a tube spotlight, and then a person rotates the rotating sleeve 1010. When the rotating sleeve 1010 rotates, the plastic strip 1008 is deflected through the connecting rope 1009, so that the plastic strip 1008 and the rectangular rod 1006 are separated, and then the rotating sleeve 1010 is pushed, and the rotating sleeve 1010 drives the circular ring 1007 to move. When the circular ring 1007 moves, it drives the moving block 1005 to move along the outside of the rectangular rod 1006, and then the plastic strip 1008 enters the second rectangular hole of the rectangular rod 1006. At this time, the rotating sleeve 1010 is released, and then the two semi-cylinders 1002 are driven to move relative to each other under the action of the rotating bar 1004 and the concave block 1003, so that the semi-cylinders 1002 and the positioning The holes 12 are separated, and then the swing ring 5 is rotated. The swing ring 5 drives the clamping assembly 10 to enter the positioning hole 12 inside the guide groove 11, which can facilitate the adjustment of the angle of the tube spotlight and limit the adjustment angle of the tube spotlight, so that the light distribution can be flexibly adjusted according to the specific space layout and the area to be illuminated, thereby more effectively achieving the lighting goal. Accurate adjustment can avoid wasting light in areas that do not need to be illuminated, reduce unnecessary energy consumption, and rotate the rotating rod 9. The rotating rod 9 limits the rotated swing ring 5. By limiting the angle, it can ensure that the light only irradiates the required area, reduce flooding, and improve energy efficiency. After the angle of the swing ring 5 is adjusted, the rotating rod 9 is rotated at this time. The rotating rod 9 supports the bottom end of the swing ring 5 to prevent the swing ring 5 from resetting after rotation, thereby supporting and fixing the rotated swing ring 5;

[0035] Then the personnel pulls the rotating sleeve 1010. When the rotating sleeve 1010 rotates, it drives the plastic strip 1008 to deflect through the connecting rope 1009, so that the plastic strip 1008 and the rectangular rod 1006 are separated. Then the rotating sleeve 1010 is pulled, and the rotating sleeve 1010 drives the circular ring 1007 to move. When the circular ring 1007 moves, it drives the moving block 1005 to move along the outside of the rectangular rod 1006. Then the plastic strip 1008 enters the first rectangular hole of the rectangular rod 1006. At this time, the rotating sleeve 1010 is released. At this time, the two semi-cylinders 1002 move relative to each other, so that the semi-cylinders 1002 and the positioning holes 12 fit together, thereby completing the fixation between the swing ring 5 and the rotating ring 6, which can facilitate the adjustment of the angle of the swing ring 5, change the difficulty of adjusting the angle of the swing ring 5, further reduce the wear between the swing ring 5 and the rotating ring 6 during swinging, and do not affect the deflection between the swing ring 5 and the rotating ring 6 under strong force.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
