[0024] The present invention will be further described below with reference to the accompanying drawings. The structure and principle of the present invention will be very clear to those skilled in the art. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention.

[0025] Example 1

[0026] As shown in FIG1-2 , the present invention discloses a rotatable LED lamp, comprising a lamp tube assembly, a rotatable device and a housing.

[0027] The lamp tube assembly includes an LED lamp board and a plurality of LED lamp beads arranged on the LED lamp board.

[0028] The LED light board includes a PCB board and a heat dissipating aluminum profile. The heat dissipating aluminum profile is provided with a handle 2. An L-shaped connecting block is provided in the middle of the handle 2. The L-shaped connecting block is used to cooperate with the heat dissipating aluminum profile and the PCB board. The base of the handle 2 is provided on the handle 2, and the two ends of the heat dissipating aluminum profile are respectively inserted into the connecting devices on the left and right sides.

[0029] There are two rotatable devices, located on the left and right sides of the LED light board, respectively, and are symmetrical on both sides, and respectively include a connecting device 4, a rotating outer sleeve 5, a rotating inner sleeve 6 and a cover assembly 7.

[0030] As shown in Figures 5-10, one side of the connecting device 4 is connected to the LED light board, and the other side of the connecting device 4 is provided with a cavity, an upwardly protruding limit block 13 is provided in the cavity, and a sliding groove 15 is provided on the edge of the cavity.

[0031] The rotating sleeve assembly includes a rotating inner sleeve 6 and a rotating outer sleeve 5 .

[0032] The rotating inner sleeve 6 is connected to the cavity of the connecting device, and an inwardly recessed limiting groove 14 is provided on the rotating inner sleeve 6. The limiting groove 14 is connected to the limiting block 13 in the cavity of the connecting device, and the limiting is achieved after buckling.

[0033] A T-shaped profile 19 and an arc profile 20 are provided on the side of the rotating inner sleeve 6 away from the LED lamp. A plurality of raised blocks are provided on the inner surface of the arc profile 20 , and elastic glue 12 is provided in the middle of the plurality of raised blocks.

[0034] An electrode sheet 11 is provided on the side of the rotating inner sleeve 6 away from the LED light board. The two electrode sheets 11 are assembled into an arc shape. A bending section is provided at both ends of the electrode sheet. The bending section is clamped on both sides of the T-profile of the rotating inner sleeve 6. The outer side of the arc-shaped electrode sheet 11 abuts against the elastic glue, and the inner side abuts against the inner electrode needle 21. The bottom is connected to a metal bending section 18 for conduction. The other end of the metal bending section 18 is bent against the PCB board 17 to achieve conduction.

[0035] The rotating outer sleeve 5 is a cylinder with an inner cavity. A slider 16 is provided on the edge of the rotating outer sleeve 5 close to the LED light board. The rotating outer sleeve 5 cooperates with the slide groove 15 of the connecting device 4 through the slider 16, so that the rotating outer sleeve can rotate within the limit range of the slide groove 15, thereby realizing a rotational friction connection with the edge of the connecting device 4.

[0036] The side of the rotating outer sleeve 5 away from the LED lamp board is connected to a metal sheet 22, an inner electrode needle 21 and a cover assembly 7.

[0037] The metal sheet 22 is fixedly connected to the rotating outer sleeve 5 , and the inner electrode needle 21 and the outer electrode needle 10 are conductively connected through the metal sheet. The inner electrode needle 21 abuts against the inner side of the electrode sheet 11 , and the outer electrode needle passes through the metal sheet 22 and extends out of the cover assembly 7 .

[0038] The cover assembly 7 is provided with a raised connecting block, which cooperates with the concave block on the rotating outer sleeve and is fixedly connected. The cover assembly 7 is provided with an outer electrode needle 10 and an inner electrode needle 21. The outer electrode needle 10 or the inner electrode needle 21 conductively connected to the outer electrode needle 10 is attached to the inner side of the electrode sheet 11. Since the electrode sheet 11 is annular and is arranged around the rotating inner sleeve 6, the inner electrode needle 21 always maintains contact with the electrode sheet 11 when it rotates relative to the rotating inner sleeve 6.

[0039] The connecting device 4 and the lamp tube assembly are in a relatively fixed state, and the rotating inner sleeve 6 and the connecting device 4 are limited by the limiting block 13 and are also in a relatively fixed state.

[0040] The rotating outer sleeve 5 , the cover assembly 7 , the metal sheet 22 , the inner and outer electrode needles and the lamp tube assembly are in relative rotation, and rotate within the range of the sliding groove 15 of the connecting device 4 .

[0041] Therefore, when the rotating outer sleeve 5 rotates relative to the rotating inner sleeve 6 and the lamp tube assembly, the metal sheet 22, the outer electrode needle 10 and the inner electrode needle 21 rotate relative to the electrode sheet 11, but they can always maintain contact, and the power supply is conducted to the PCB board 17 through the outer electrode needle 10, the metal sheet 22, the inner electrode needle 21, the electrode sheet 11, and the metal bending section 18.

[0042] Example 2

[0043] As shown in FIG3-4, based on the first embodiment, the light board of this embodiment adopts a double-sided LED light board, and the lamp tube assembly includes two LED light boards and a plurality of LED lamp beads arranged on the LED light boards.

[0044] Specifically, the LED light board includes a plastic heat insulation board 1, a heat dissipation aluminum profile, a PCB board and a handle 2.

[0045] The plastic heat insulation board 1 is arranged in the middle, and two heat dissipation aluminum profiles are respectively arranged on both sides of the plastic heat insulation board 1, with a gap left between the plastic heat insulation board 1 and the heat dissipation aluminum profiles.

[0046] PCB boards are provided on the outside of the two heat dissipation aluminum profiles, and the two PCB boards are respectively connected to the connection devices on both sides.

[0047] The handle 2 is arc-shaped and is used to separate and connect the plastic insulation board 1 and the heat dissipation aluminum profile. A groove is provided in the middle of the handle 2, which is used to cooperate with the connection of the plastic insulation board 1. L-shaped connecting blocks are provided on both sides of the groove of the handle 2. The L-shaped connecting blocks are stuck in the gap between the plastic insulation board 1 and the heat dissipation aluminum profile and are connected with the heat dissipation aluminum profile. The two ends of the heat dissipation aluminum profile are inserted into the connecting device and connected by screws.

[0048] The specific assembly method is as follows;

[0049] 1. The lamp tube assembly is the basic skeleton component, which is assembled by the lamp panel assembly, heat dissipation aluminum profile, handle, heat shield 1, left and right fixing brackets and screws.

[0050] 2. Right Side Assembly: As shown in Figure 1, secure the right-rotating outer sleeve 5, right-rotating inner sleeve 6, eight flat washers, and self-tapping screws to the lamp assembly. Ensure a secure connection. Then, snap the right cover assembly 7 onto the right-rotating outer sleeve 5 to complete the right side assembly.

[0051] 3. Rotation Inspection: After completing the assembly steps in step 2 above, rotate the outer sleeve 5 until the boss is at the starting point. Apply slight force in a clockwise direction until the boss passes the high point, until you hear a sound or feel it. Then rotate smoothly. After rotating 90°, apply slight force until the boss passes the high point, reaching the end point when you hear a sound or feel it.

[0052] The rotating outer sleeve 5 can only rotate within the 90° range shown in the figure. Repeat the experiment several times. If the rotation is smooth and there is a sound or a feel when passing the high point, it is considered qualified.

[0053] 4. Left side assembly and rotation inspection: The steps are similar to steps 2 and 3 above.

[0054] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent replacement or change made by any technician familiar with the technical field within the technical scope disclosed by the present invention based on the technical solution and novel concept of the present invention should be covered by the scope of protection of the present invention.
