[0033] Embodiment 1:

[0034] Please refer specifically to Figure 1-2 , a rotary high-efficiency LED lamp, comprising a lamp body 1. The lamp body 1 includes a base 11, a light-transmitting cover 12 disposed on the base 11, and a heat dissipation plate 13 disposed inside the base 11. The heat dissipation plate 13 is made of aluminum alloy and has good heat conduction and heat dissipation effects. An installation ring 111 is disposed inside the base 11, and a disc-shaped first lamp bead board 14 is disposed on the installation ring 111. Connection holes are provided at corresponding positions on the installation ring 111 and the first lamp bead board 14, and fasteners can be installed in the connection holes for fixing the first lamp bead board 14. A circular second lamp bead board 15 is disposed on the heat dissipation plate 13. Connection holes are provided at corresponding positions on the heat dissipation plate 13 and the second lamp bead board 15, and fasteners can be installed in the connection holes for fixing the second lamp bead board 15. A number of LED lamp beads are disposed on both the first lamp bead board 14 and the second lamp bead board 15. A driver 16 is disposed on the back of the base 11. The driver 16 is electrically connected to the first lamp bead board 14 and the second lamp bead board 15. Most of the light emitted by the first lamp bead board 14 is emitted downward through the light-transmitting cover 12, and a part of the light emitted by the second lamp bead board 15 is emitted downward through the light-transmitting cover 12 and another part is emitted toward the side through the light-transmitting cover 12. The two groups of light sources work simultaneously to increase the illumination area, making the overall light-emitting effect better, having the effect of high light efficiency, and improving the user experience.

[0035] Only a small part of the first lamp bead board 14 is in contact with the mounting ring 111, so a heat dissipation cavity 17 is formed between the mounting ring 111 and the first lamp bead board 14, and the heat dissipation cavity 17 plays a role in heat dissipation.

[0036] The ratio of the wall thickness h of the outer wall of the base 11 to the height H of the light-transmitting cover 12 is 1:10. In this embodiment, the wall thickness h of the outer wall of the base 11 is 8 mm, then the height H of the light-transmitting cover 12 is 8 cm. The ultra-thin base with the ultra-high light-transmitting cover 12 makes the transmission area of the LED lamp larger and the light illumination effect better.

[0037] Embodiment 2:

[0038] Please refer specifically to Figure 1-6 On the basis of Embodiment 1, a rotary high-light-efficiency LED lamp further includes a bracket 2. The bracket 2 is a stepped disc-shaped structure, and its cross-section is a stepped structure. Four waist-shaped through holes 21 are provided on the bracket 2, and the waist-shaped through holes 21 can be penetrated by fasteners, that is, the bracket 2 can be fixed on the ceiling through fasteners. A downward-extending insertion ring 22 is provided on the bracket 2, and four first rotating fasteners 23 are provided on the outer wall of the insertion ring 22. The four first rotating fasteners 23 are equally spaced, and the centers of adjacent two first rotating fasteners 23 are 90° apart; four second rotating fasteners 112 are provided on the back of the base 11. The four second rotating fasteners 112 are equally spaced, and the centers of adjacent two second rotating fasteners 112 are 90° apart. The number of the first rotating fasteners 23 is the same as that of the second rotating fasteners 112, the second rotating fasteners 112 are adapted to the first rotating fasteners 23, and the first rotating fasteners 23 can be rotatably inserted into the second rotating fasteners 112, that is, the lamp body 1 is clamped and separated from the bracket 2 by rotation, so that the lamp body 1 is convenient and simple to load and unload and will not damage the ceiling.

[0039] A convex rib 24 is provided on the first rotating fastener 23, and a groove 113 is provided at the top of the second rotating fastener 112. The groove 113 is adapted to the convex rib 24. When the first rotating fastener 23 and the second rotating fastener 112 are assembled in place, the convex rib 24 will be stuck into the groove 113 to form a clamping fit, locking the first rotating fastener 23 and the second rotating fastener 112, that is, locking the lamp body 1 and the bracket 2, so that a certain external force is required for the lamp body 1 to be separated from the bracket 2.

[0040] One end of the first rotating fastener 23 is provided with an arc surface, which can reduce the collision between objects compared with a right-angle surface, facilitating the entry of the first rotating fastener 23 into the second rotating fastener 112; the other end is provided with a stop wall 25, and the stop wall 25 plays a role in limiting. When the first rotating fastener 23 and the second rotating fastener 112 are assembled in place, the stop wall 25 will abut against the upper end of the second rotating fastener 112, preventing the first rotating fastener 23 from leaving the second rotating fastener 112 from the other end.

[0041] One end of the top surface of the second rotating fastener 112 is also provided with an arc surface, which facilitates the entry of the first rotating fastener 23 into the second rotating fastener 112.

[0042] The first rotating fastener 23 and the retaining wall 25 are of an integral structure, and the two form an inverted L shape.

[0043] A large through hole 26 is provided at the middle position of the bracket 2. The large through hole 26 serves the purpose of wire routing, and at the same time reduces the consumption of raw materials and lowers the production cost.

[0044] An arc-shaped notch 27 is provided above the first rotating fastener 23. When the first rotating fastener 23 and the second rotating fastener 112 are assembled in place, the upper half of the second rotating fastener 112 will block the arc-shaped notch 27 to prevent mosquitoes, dust, etc. from entering the lamp body 1 through the arc-shaped notch 27.

[0045] The present utility model is a rotary high-efficiency LED lamp, and its working principle is described in conjunction with the accompanying drawings:

[0046] Installation method of the LED lamp: First, fix the bracket 2 to the ceiling through fasteners. Then align the lamp body 1 with the bracket 2. The first rotating fastener 23 and the second rotating fastener 112 need to be staggered and close to the lamp body 1 and the bracket 2. Rotate the lamp body 1 counterclockwise, and the first rotating fastener 23 will enter the second rotating fastener 112 until the lamp body 1 can no longer be rotated. At this time, the convex rib 24 will snap into the groove 113 to form a snap-fit connection, completing the installation of the lamp body 1.

[0047] Disassembly method of the LED lamp: Rotate the lamp body 1 clockwise, and the first rotating fastener 23 will be separated from the second rotating fastener 112. When the first rotating fastener 23 is completely separated from the second rotating fastener 112, the lamp body 1 can be disassembled from the bracket 2, completing the disassembly of the lamp body 1.

[0048] The above shows and describes the basic principles, main features and advantages of the present utility model.
