Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and more specifically, to a modular smart LED street lamp with an adjustable mounting angle. Background Art

[0002] With the continuous development and improvement of LED technology, smart LED street lights, as highly efficient, energy-efficient, and intelligently managed lighting devices, are increasingly being used in urban roads, public spaces, and other fields. Smart LED street lights typically integrate multiple functional devices, enabling them to perform a variety of functions beyond basic lighting, thus providing diverse services and convenience for urban development and residents' lives.

[0003] The functional devices of smart LED street lights in the existing technology are usually set up as a whole device at the factory, without modular design. This means that when a component is damaged, the entire street light needs to be replaced instead of just replacing the faulty module. This increases the difficulty and cost of maintenance and leads to waste of resources. In addition, when certain functions need to be upgraded or replaced, the entire street light needs to be replaced instead of just updating the relevant modules, which limits the flexibility and scalability of the street light. It also restricts users from customizing the configuration according to specific needs and cannot meet the installation requirements in different scenarios. In addition, the installation direction and installation angle of the functional devices are fixed, making it difficult to selectively install according to the actual installation scenario. This limits the flexible installation of street lights in different scenarios, may affect the performance of some functional devices, and makes it difficult to ensure that each functional device can perform at its best. Additional adjustments or modifications may be required, increasing the complexity and cost of installation. Summary of the Invention
