[0047] The implementation principle of the LED street lamp for road lighting in the embodiment of the present application is as follows: the cooperation of the electric push rod 71 and the connecting rod 72 facilitates the operator to move the position of the installation rod 621, and the cooperation of the installation rod 621, the first plug-in block 622 and the second plug-in block 623 can realize the synchronous or independent rotation of the first winding roller 51 and the second winding roller 52. The operator winds up the first traction line 53 and the second traction line 54 at the same time through the synchronous rotation of the first winding roller 51 and the second winding roller 52, and the first traction line 53 and the second traction line 54 drive the rod body 4 and the installation ring 2 to rise until the installation ring 2 reaches the set height.

[0048] The operator then makes one side of the rod body 4 fall down through the cooperation of the electric push rod 71 and the connecting rod 72. When the rod body 4 changes from a vertical state to a horizontal state, the rod body 4 drives the limit bar 21 to insert into the limit groove 15, thereby fixing the position of the mounting ring 2. At this time, the operator makes the other side of the rod body 4 fall down through the cooperation of the electric push rod 71 and the connecting rod 72, and then relaxes the first traction line 53 and the second traction line 54, thereby making the second connecting bar 45 move downward under the elastic force of the fifth spring 48, and the second connecting bar 45 drives the first connecting bar 41 to move through the inclined surface until the first connecting bar 41 is inserted into the mounting ring 2, thereby finally improving the stability of the rod body 4.

[0049] When the operator tightens the first traction line 53 and the second traction line 54 again through the first winding roller 51 and the second winding roller 52, the plug-in cooperation between the first connecting strip 41 and the mounting ring 2, and the limit strip 21 and the limit groove 15 can be quickly released, so that the operator can move the mounting ring 2, the LED lamp head 12 and the solar panel 13 downwards. The operator can flexibly adjust the height of the LED lamp head 12 and the solar panel 13, so that the operator can perform maintenance or replacement conveniently.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
