Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of street lamp installation, in particular to a street lamp with a large-arc lamp pole seamlessly welded. Background Art
[0002] In order to make the street lamps more beautiful and to provide more comprehensive coverage of the road surface with light, curved street lamps that are seamlessly welded are often used. The curved street lamps are used to place the light source in the center of the road surface.
[0003] The lamp pole of a street lamp is generally a hollow pole connected to the base by bolts, and the base is fixed by pouring concrete. However, for street lamps with a larger curvature, the center of gravity is offset, so that the bolts on the side close to the light source are subjected to greater force. Under the influence of environmental factors (strong wind environment, rain corrosion), long-term use will cause the bolts to be damaged and the lamp pole to bend further, affecting the illumination angle of the light source.

[0007] Multiple limiting members are fixedly connected to the upper end of the mounting plate around the circumference of the hollow rod, and are spaced apart from the hollow rod. Multiple second supporting members are respectively installed between the corresponding limiting members and the hollow rod.
