[0002] The power driver for LED streetlights is usually located in the power compartment inside the lamp body. When an LED streetlight malfunctions and needs repair, the entire lamp needs to be removed from the pole before the power supply can be replaced. To facilitate power supply replacement, some streetlights currently use a split structure, where the driver power supply is externally located at the bottom of the pole and connected to the lamp head at the top of the pole via a power cable. However, multiple electrical devices, such as individual lamp controllers, are usually installed at the bottom of the pole. The internal space of the pole is limited, the wiring is complex, and maintenance is inconvenient. Utility Model Content

[0003] Based on this, the present invention provides a multi-functional power supply box for split-type LED street lights, which can be installed on the outer wall of the light pole without taking up internal space of the light pole, facilitating wiring, and has the advantages of high heat dissipation, high IK rating, and flexible installation.

[0019] Please refer to Figures 1-4 A multifunctional power supply box for split-type LED streetlights includes an inner shell 11, an outer shell 12, an upper cover 21, a lower cover 22, and a clamping assembly. The inner shell 11 and the outer shell 12 are rectangular channel shells with openings at both ends along the upper and lower axes. The outer shell 12 is fitted around the outer ring of the inner shell 11. Several strip-shaped reinforcing ribs 13 connect the inner shell 11 and the outer shell 12. The reinforcing ribs 13 divide the space between the outer wall of the inner shell 11 and the inner wall of the outer shell 12 into several heat dissipation vents aligned with the opening directions at both ends of the inner shell 11. The heat inside the inner shell 11 is dissipated through airflow. The inner shell 11, outer shell 12, and reinforcing rib 13 are integrally formed by aluminum extrusion in the mold, simplifying the production and assembly steps. The reinforcing rib 13 can enhance the impact resistance of the inner shell 11 and outer shell 12, improving the overall IK protection level of the power supply box. At the same time, the heat on the inner shell 11 is transferred to the reinforcing rib 13 through heat transfer, and then transferred from the reinforcing rib 13 to the surface of the outer shell 12 to further increase the heat dissipation area, thereby improving the heat dissipation effect of the power supply box.

[0020] The outer wall of the opening of the inner shell 11 is provided with several positioning posts. The upper cover 21 and the lower cover 22 are provided with several positioning holes.

The inner shell 11 is provided with a power supply placement position. The lower cover 22 is provided with two wire passage holes. Each wire passage hole is provided with a through-type sealing plug 23. The power supply wires 5 entering and exiting the power supply are respectively passed through the through-type sealing plugs 23 in the wire passage holes. The through-type sealing plugs 23 and the power supply wires 5 are press-fitted to achieve a seal. The power supply is placed in the power supply placement position. Then, heat dissipation glue is filled between the power supply placement position and the inner wall of the inner shell 11 to improve the heat dissipation rate of the power supply in the inner shell 11. After the sealing rings 4 are fitted, the upper cover 21 covers the upper opening of the inner shell 11 and is then fixed with screws.

[0021] The outer wall of the outer casing 12 is provided with two slots 14 extending in the same direction as the openings at the upper and lower ends of the outer casing 12. The clamp assembly includes an arc-shaped clamp 31 and several bolts 32 and nuts 33. The arc-shaped clamp 31 is provided with connecting parts on both sides. The upper and lower ends of the connecting parts are provided with through holes. The heads of two bolts 32 are respectively clamped in each slot 14. The shank of the bolt 32 passes over the outer wall of the lamp post and then passes through the through hole and is screwed into the nut 33, thereby fixing the power box to the outer wall of the lamp post.

[0022] Furthermore, the outer wall of the slot 14 is provided with a reinforcing plate, one side of which is connected to the outer wall of the slot 14 and the other side of which is connected to the outer wall of the outer shell 12, thereby improving the structural strength of the slot 14.
