Since the top of the second rotating shaft 644 is fixedly connected with the bottom of one of the second gears 643, the second rotating shaft 644 can rotate synchronously with the second gear 643, and power is further transmitted to the subsequent components. And the bottom of one of the second gears 643 is fixedly connected with the top of the second rotating shaft 644.

And the bottom of the circular connecting column 647 is movably connected with the center of the fan blade 648.

[0033] The dustproof device 65 comprises a connecting block 651, the top of the connecting block 651 is fixedly connected with the bottom outer surface of the water tray 5, a movable block 652 is arranged in the middle groove of the connecting block 651, and the middle groove of the connecting block 651 is movably connected with the top of the movable block 652, a telescopic column 653 and a spring 654 are arranged at the center bottom of the movable block 652, and the center bottom of the movable block 652 is fixedly connected with the top of the telescopic column 653 and the spring 654, and the bottom of the spring 654 is fixedly connected with the outer side protruding part of the bottom of the telescopic column 653.

Since the bottom of the telescopic column 653 is movably connected with the curved rods 655, the tension generated by the contraction of the spring 654 will be transmitted to the curved rods 655 through the telescopic column 653. At this time, the curved rods 655 will quickly drive the bottom fixedly connected semicircular plates 656 to expand outward along the arc-shaped outer surface of the lamp 4. The bottom of the semicircular plate 656 is in the shape of a circular arc, and after expansion, an arc-shaped protection surface covering the side of the lamp 4 can be formed, which can not only guide the rainwater to drip along the edge through the curved surface structure to realize the waterproof function, but also block the dust particles in the air from directly invading the inside of the lamp 4, and at the same time, the extension of the arc surface can enhance the sun-shading effect by fitting with the arc of the lamp 4, and form a multi-dimensional protection barrier. The bottom of the two curved rods 655 is fixedly connected with the outer surface of the semicircular plate 656.

[0035] The working principle of the application is as follows:

[0036] The heat dissipation of the LED outdoor lighting lamp mainly relies on the heat dissipation device 6, the swinging device 63 and the rotating device 64 are driven by the motor 61 to realize multi-directional blowing heat dissipation of the LED lighting lamp 3. After the motor 61 is started, the connecting rods 62 on both sides are driven to move, and then the swinging device 63 is driven to move up and down, and the rotating device 64 is driven to move synchronously. By blowing at different positions of the rotating device 64, the heat generated by the LED lighting lamp 3 during work can be taken away, and the heat dissipation efficiency is improved.

[0037] Active position heat dissipation: the motor 61 will first drive the connecting rod 62 to move, and then drive the threaded rod 632 connected with the rotating column 633 to rotate. Since the outer surface of the threaded rod 632 is in mesh with the outer surface of the first gear 635, the rotation of the threaded rod 632 will drive the first gear 635 to rotate synchronously. At the same time, the first rotating shaft 636 fixedly connected with the first gear 635 will drive the swing rod 637 at both ends to swing under the support of the support frame 634, so that the rotating device 64 at the bottom of the swing rod 637 can realize up-down reciprocating motion;

[0038] Accelerate heat dissipation: the rotating device 64 includes two second gears 643, when the motor 61 drives the two second gears 643 to rotate again, the second rotating shaft 644 fixedly connected with one of the second gears 643 will rotate and transmit power to the third gear 645. Since the outer surface of the third gear 645 is in mesh with the inner gear 646, when the second rotating shaft 644 swings in the groove at the top of the third gear 645, the third gear 645 can only move along the inner side of the inner gear 646, so as to drive the bottom circular connecting column 647 and the fan blade 648 to realize self-rotation swing, so that the airflow blown covers a larger area around the LED illuminating lamp 3, and the heat dissipation effect is enhanced;

[0039] Dustproof principle: the dustproof device 65 includes a movable block 652, when the movable block 652 is lifted upward by the external force, the originally stretched spring 654 loses the tension, and the elastic potential energy is used for contraction. When the spring 654 contracts, the tension is transmitted to the two curved rods 655 through the telescopic column 653, so that the curved rods 655 can drive the bottom semicircular plate 656 to expand outward along the arc-shaped outer surface of the lamp 4. The expanded semicircular plate 656 forms an arc-shaped protective surface, which can block dust particles in the air from entering the inside of the lamp 4, and realizes the dustproof function;

[0040] Waterproof principle: the bottom of the semicircular plate 656 is in arc shape, and the arc-shaped protective surface formed after expansion can guide rainwater to drip along the edge, preventing rainwater from entering the inside of the lamp 4. At the same time, the arc-shaped design of the lamp 4 itself can also reduce the accumulation of rainwater, and the arc-shaped cover 2 can isolate the external rainwater, and cooperate with the dustproof device 65 to realize the waterproof function. In addition, the water storage tray 5 can store water in rainy days, and the water evaporation can assist in cooling, further enhancing the heat dissipation and protection performance of the lamp.

[0041] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described.
