Description

Technical Field

[0001] The utility model relates to the field of street lamps, and more specifically, to a high-stability high-pole LED street lamp. Background Art

[0002] High pole street lights are generally installed at higher positions to achieve long-distance lighting. They are usually installed in places that require large-area lighting, such as urban roads, highways, squares, and parking lots. High pole street lights have a large lighting range and a wide coverage area. They can provide sufficient lighting, increase the visibility of vehicles and pedestrians at night, and thus improve the safety of roads and public places.

[0003] The existing high pole street lamps have the problem that the structure of the connection between the lamp pole and the embedded parts is not strong enough. Sometimes the structural design of the connection between the lamp pole and the embedded parts may not be strong enough, or in actual installation, the fixing nut is not installed correctly or is loose, causing the lamp pole to shake or tilt under bad weather conditions such as wind and rain, thus affecting the normal use and safety of the street lamp. In addition, the fixing nuts of traditional street lamps are exposed to rain for a long time and are easily corroded by moisture and oxides in the air, which causes the nuts to rust and corrode. When the nuts are rusted and corroded, their fixing effect will be affected, which may cause the nuts to loosen or be damaged, thus affecting the fixation and stability of the entire street lamp.
