[0036] Embodiment 1:

[0037] like Figures 1 to 5 A rotating lampshade floodlight is provided, which comprises a lamp pole 10, a lamp holder 20 and a lampshade 30.

[0038] The lampshade is a cylindrical lampshade. In order to obtain a better hand feel, the outer wall of the lampshade is provided with patterns. The upper end of the lampshade is provided with four mounting joints 33, and the four mounting joints are provided with screw holes. The lower end of the lampshade is provided with a light-transmitting sheet 31. The light-transmitting sheet 31 has different colors along the circumference of the lampshade, and can also be provided with different patterns. The light-transmitting sheet is provided with a light-transmitting hole 32, and the light-transmitting hole 32 is offset to one side of the light-transmitting sheet.

[0039] The lamp pole 10 is mounted with a lampshade turntable 40, which is rotatably matched with the lamp pole. The lampshade turntable 40 is mounted on the lamp pole through two rolling bearings 41, and the upper end of the lamp pole extends out of the lampshade turntable. The lampshade turntable is provided with four through holes 42 corresponding to the mounting joints 33 of the lampshade. The upper end of the lampshade is mounted on the lampshade turntable through bolts 43. When the lampshade is moved, the lampshade will freely rotate around the lamp pole.

[0040] A lamp holder 11 is disposed at the lower end of the lamp pole 10, and the lamp holder 11 is located inside the lamp shade. The lamp holder is a plate-shaped structure, and is provided with a lamp holder mounting hole 13, and the lamp holder mounting hole 13 is offset to one side of the center line of the lamp pole.

[0041] The lamp holder 20 is mounted on the lamp frame 11 through the lamp holder mounting hole 13. The lamp holder is located on one side of the rotation axis of the lamp shade, that is, offset from the rotation axis of the lamp shade, and the lamp holder projects light to the lower end of the lamp shade.

[0042] In order to make the lampshade naturally reset, that is, the lampshade stays at the same position every time the rotation stops, the rotation reset device of this embodiment includes: the lampshade turntable 40 is provided with a reset cam 50, the reset cam 50 is fixed on the lampshade turntable 40, and rotates synchronously with the lampshade (and the lampshade turntable), and the reset cam is a plane cam, and the cam surface faces downward, that is, toward the lampshade turntable 40. The reset cam is provided with a reset point 51 and a compression vertex 52, the reset point 51 is at the farthest position from the lamp holder 11, and the compression vertex 52 is at the closest position to the lamp holder 11, and the reset point and the compression vertex are 180° apart in the circumferential position.

[0043] An elastic roller 60 is provided on the lamp holder 11, and the elastic roller is arranged on the side opposite to the lamp holder 20. The structure of the elastic roller includes a roller bearing 61, a spring sleeve 62, a telescopic rod 63 and a pressure spring 64. The spring sleeve 62 is fixed on the lamp holder 11, and the spring sleeve 62 is provided with a square hole 65. The pressure spring 64 is installed in the square hole 65. The telescopic rod 63 is a square shaft that slides with the square hole 65. The roller bearing 61 is installed at the upper end of the telescopic rod. The pressure spring 64 presses the telescopic rod upward, so that the roller bearing 61 elastically presses the reset cam 50. The reset cam 50 and the elastic roller 60 press each other, and the telescopic rod moves in a vertical direction (along the axis of rotation of the lampshade). At the reset point 51 of the reset cam, the elastic roller is in the maximum extension position, and at the compression vertex 52 of the reset cam, the elastic roller is in the maximum compression position. When the reset cam rotates, it presses the elastic roller to make it move in a telescopic manner. When the lampshade stops rotating, the elastic roller presses the reset cam and pushes the reset cam to rotate through the inclined surface of the plane cam, so that the reset cam stops at the position where the reset point 51 contacts the elastic roller. This position is the natural stop position of the lampshade. Figure 2 , Figure 4 At the natural stop position of the lampshade (i.e. when the lampshade stops rotating), the position of the light transmission hole 32 of the lampshade corresponds to the lamp cap, so that the lampshade maintains sufficient illumination at the natural stop position.

[0044] The rotating lampshade floodlight of this embodiment, when the lampshade rotates, the light emitted by the lamp head is projected from the lower end of the lampshade. When the lampshade rotates, the light passes through the rotating light-transmitting sheet 31, and can project light of different colors and different patterns, so that the lamp produces a changing light-emitting effect, which has artistic appeal. When the lampshade is in a static state, the light is projected through the light-transmitting hole, maintaining a natural lighting state, avoiding the state of multiple lamps producing messy light in a conventional static state.

[0045] The lamp holder and circuit part are encapsulated inside the lamp, isolating people from the internal circuit and avoiding the danger of touching the lamp. The lampshade can be turned and rotated, which is particularly suitable for installation and use in locations such as handrails and short columns.

[0046] like Figures 9 to 12 The upper end of the lamp pole is provided with a hanging joint 80, which is sleeved on the upper end of the lamp pole through the inner hole and fixed on the lamp pole by a set screw 83. A gasket 84 is provided between the hanging joint 80 and the rolling bearing 41 of the lamp shade turntable 40 to ensure the normal rotation of the lamp shade turntable.

[0047] The mounting joint is hinged with a mounting frame 81 through a bolt 85, and the mounting frame 81 is provided with two mounting bolts 86 and fixed to the handrail 82 through the mounting bolts 86. In order to match the circular handrail, the contact surface 87 of the mounting frame 81 and the handrail is a curved surface.

[0048] The mounting joint is hinged with the mounting frame 81, so that the lamp can be vertically mounted on the inclined handrail. Fig.12 shown.

[0049] In order to avoid the wires being exposed, the mounting frame 81 is provided with a threading hole 88, the mounting joint 80 is provided with a threading hole 89, and the lamp pole is provided with a threading hole 14, through which the wires are connected to the interior of the lamp.

[0050] The rotating lampshade floodlight of the present invention is also suitable for being installed on a short column.

[0051] Embodiment 2:

[0052] like Figures 6 to 8 , a rotating lampshade floodlight. This embodiment is a structural replacement of the first embodiment.

[0053] This embodiment adopts another structure that allows the lampshade to return to its original position naturally.

[0054] A reset driving wheel 71 is provided on the lampshade turntable 40 . The reset driving wheel 71 is provided with a bevel gear 74 . The bevel gear 74 of the reset driving wheel faces downward. The reset driving wheel 71 and the lampshade turntable 40 rotate synchronously coaxially.

[0055] The lamp pole 10 is provided with a reset shaft 12 extending laterally, the reset shaft 12 is perpendicular to the lamp pole, that is, also perpendicular to the rotation axis of the lampshade turntable 40, and a reset wheel 70 is mounted on the reset shaft 12, and the reset wheel 70 is also provided with a bevel gear 73. The bevel gear 73 of the reset wheel and the bevel gear 74 of the reset drive wheel are bevel gears with the same number of teeth and mesh with each other, and the rotation axes of the reset wheel 70 and the reset drive wheel 71 intersect each other perpendicularly.

[0056] The reset wheel is provided with an eccentric counterweight 72 .

[0057] When the lampshade rotates, the reset drive wheel rotates synchronously with the lampshade, and the transmission ratio between the reset wheel and the reset drive wheel is 1:1, and the reset wheel and the reset drive wheel rotate at the same speed. When the lampshade stops rotating, the reset wheel will stop at the position where the counterweight block naturally droops, and drive the lampshade to stop at the natural stop position through the reset drive wheel, that is, the light transmission hole 32 of the lampshade corresponds to the position of the lamp head, such as Figure 7 shown.

[0058] This embodiment can reduce the mechanical friction and mechanical vibration of the natural reset mechanism of the lampshade, and improve the working stability and service life of the mechanical structure.
