At the same time, it facilitates disassembly and repair of the street light in case of damage, effectively improving the efficiency of later maintenance.

[0021] Specifically, the adjustment assembly includes: a positioning toothed plate 2 connected to the outside of the LED lamp housing 1, and an arc-shaped toothed disc 4 connected to the end of the connecting sleeve 3; wherein, a positioning shaft 5 is provided inside the LED lamp housing 1, one end of the positioning shaft 5 is movably connected to the center of the arc-shaped toothed disc 4, and the arc-shaped toothed disc 4 is configured to cooperate with the positioning toothed plate 2. Adjustment grooves are provided on both sides of the surface of the arc-shaped toothed disc 4, and locking bolts for controlling the engagement and fixation of the arc-shaped toothed disc 4 with the positioning toothed plate 2 are provided inside the adjustment grooves.

[0022] In addition, the positioning tooth plate 2 is a structure that cooperates with the arc-shaped toothed disc 4 to achieve fixation at different angles and ensure the lighting effect of the street light. The positioning shaft 5 plays a major limiting role in the installation of the connecting sleeve 3, effectively preventing the LED lamp housing 1 and the connecting sleeve 3 from separating. The locking bolt is used to fix the position of the adjusted LED lamp housing 1 and the connecting sleeve 3.

[0023] The mounting assembly includes: a fixed mounting plate 15 movably mounted inside the mounting slot 8, and a mounting protrusion 18 connected to the top of the inner wall of the fixed mounting plate 15; wherein, a connecting seat 16 is connected to the bottom of the inner wall of the fixed mounting plate 15, and the connecting seat 16 is snapped into the inner wall of the mounting slot 8.
