The connector 4 is fixed on the outside of the housing 1 and is used to connect to the street lamp pole.

[0028] The housing 1 includes an upper housing 11 and a lower housing 12 which are fastened together, and a cavity is formed between the upper housing 11 and the lower housing 12. In the present embodiment, the upper housing 11 is plate-shaped, and the lower housing 12 is generally a box body, and its box opening is arranged upward. The edge of the upper housing 11 and the edge of the box opening of the lower housing 12 are fixedly connected by a plurality of fixing springs. Specifically, the longitudinal section of the fixing spring is C-shaped, and the edge of the upper housing 11 and the edge of the box opening of the lower housing 12 fit together and are clamped in the C-shape, and the controller and the battery 3 are accommodated in the cavity.

[0034] Furthermore, a waterproof boss 1213 is provided on the inner bottom surface of the first part 121 , and the cross-section of the waterproof boss 1213 is U-shaped. The two arms of the U-shape are respectively fixed to the inner wall surfaces on both sides of the air outlet 1212 to prevent rainwater from entering the lower shell 12 from the air outlet 1212 .

[0035] In this embodiment, there is a ventilation duct 13 between the plurality of air inlets 1223 and the plurality of air outlets 1212, which is used to ventilate, dissipate heat and cool down the battery 3 and the lighting assembly 2. Specifically, the ventilation duct 13 is a cavity formed between the upper shell 11 and the lower shell 12. In addition, the plurality of air inlets 1223 are lower than the plurality of air outlets 1212.
