Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: a novel LED street lamp with adjustable illumination brightness and range comprises a hollow upright post 1, wherein a main lamp body 2 is installed at the top of the upright post 1, grooves 3 are inwards formed in two sides of the upper end of the upright post 1, the top of each groove 3 is provided with an opening, a partition plate 4 is arranged in the upright post, and a threaded shaft 5 is rotatably installed between each partition plate 4 and the top of the upright post 1;

the lower extreme cover of threaded shaft 5 is equipped with driven gear 6, and one side is provided with driving motor 7, and driving motor 5 is step motor, but instantaneous start or stop, but the accurate control rotational speed, installs driving gear 8 on driving motor 7's the output shaft, and driving gear 8 and driven gear 6 intermeshing are equipped with big nut 9 on the threaded shaft 5, and the both sides of big nut 9 are fixed with movable block 10 respectively, and compensation lamp body 11 is installed to the bottom of movable block 10.

The two moving blocks 10 are fixedly provided with sliding strips 12 on the separated side, sliding grooves 13 are formed in the two sides, opposite to the sliding strips 12, of the upright post 1, the sliding strips 12 are matched with the sliding grooves 13 and are arranged in the sliding grooves 13, when the moving blocks 10 move up and down, the sliding strips 12 can slide in the sliding grooves 13, and the moving blocks 10 can be limited while the moving blocks 10 are stabilized.
