Description

Technical Field

[0001] The utility model relates to the technical field of combined street lamps, and more specifically, to a combined street lamp. Background Art

[0002] In the existing technology, although the design and functions of combined street lamps are diverse, there are still some problems and limitations, which affect the flexibility of use, maintenance efficiency and long-term stability of street lamps.

[0003] Firstly, traditional street lamp designs often adopt a fixed structure with a preset and non-adjustable height. This design may not be flexible enough in certain environments and cannot adapt to the specific lighting needs of different roads or areas. For example, in some occasions where the lighting height needs to be lowered to reduce light pollution or improve lighting efficiency, street lamps with a fixed height may not be able to meet these needs, resulting in poor lighting effects or energy waste.

[0004] Secondly, the connection and disassembly operations between street lamps and mounting frames are usually cumbersome and complicated. In the prior art, when a single street lamp is damaged or needs to be replaced, complex maintenance operations are often required, such as using special tools, following cumbersome steps or requiring professional skills. This not only consumes time and human resources, but may also lead to maintenance delays, affecting road lighting effects and traffic safety.

[0005] In addition, although some devices in the prior art use some mechanisms to achieve rapid installation and disassembly of street lamps, the structures of these mechanisms are often too simple and cannot ensure stability after installation. This design may provide convenience in a short period of time, but in long-term use, due to the influence of external factors such as strong winds, the simple connection mechanism may gradually loosen, causing the position of the street lamp to shift or the stability to decrease, which will not only affect the lighting effect, but may also cause the street lamp to fall, causing safety hazards and affecting traffic safety.
