[0021] The sleeve 4 includes a cylinder 401 and a fixing plate 402 welded to the upper end of the cylinder 401 . The cylinder 401 is sleeved on the upper end of the lamp pole 1 . An adjusting screw 403 is provided on the side wall of the cylinder 401 . The size of the fixing plate 402 is larger than that of the through slot 6 .

[0022] A card slot 501 is provided on the upper side of the bracket cover 5, and a card block 701 engaged in the card slot 501 is fixedly provided on the upper side of the bracket base plate 7. A fastening screw 702 connected to the photovoltaic panel 9 is provided on the card block 701. One side of the bracket base plate 7 is U-shaped, and the power box 8 is engaged in the U-shaped bracket base plate 7 and the two ends of the power box 8 correspond to the two ends of the U-shaped opening of the bracket base plate 7. The bracket cover 5 is provided with heat dissipation grooves 502 at the positions corresponding to the two ends of the power box 8.

[0023] The LED lamp head 3 is electrically connected to the power box 8 through the cable 10 and passes through the lamp pole arm 2, the lamp pole 1, the sleeve 4, the bracket cover 5 and the bracket base plate 7. The power box 8 is electrically connected to the photovoltaic panel 9 and the controller 11 through the cable 10. The controller 11 is fixedly arranged on the lower side of the photovoltaic panel 9.

[0024] A microwave sensor 12 is fixedly mounted at the lower part of the LED lamp holder 3 , and the microwave sensor 12 is connected to the controller 11 via a wire.

The fixing between the sleeve 4, the bracket cover 5, the bracket bottom plate 7, the power box 8 and the photovoltaic panel 9 only needs to fix the fasteners between the sleeve 4 and the bracket bottom plate 7 and the bracket bottom plate 7 and the photovoltaic panel 9 to form an integral structure. Therefore, the overall structure is simple, the cost is low, and the maintenance is convenient.
