Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of street lamps, and more particularly to an expandable LED intelligent street lamp. BACKGROUND

[0002] Street lamps are indispensable public facilities in modern cities, providing basic lighting at night and serving as an important tool to ensure social operation and the safety and convenience of citizens' life, significantly reducing traffic accidents. Street lamps also serve the function of beautifying the city, and their diversified shapes and light color designs can create a unique night landscape and enhance the image of the city.

[0003] Traditional street lamps only provide basic lighting functions and cannot provide any additional services such as environmental monitoring, security monitoring, information publishing, and emergency calls in addition to illuminating the road. Many intelligent street lamps on the market are designed in an integrated manner, integrating all intelligent functions (sensors, cameras, communication modules, etc.) with the lamp pole and the lamp head, which results in extremely high initial procurement costs and leaves no room for subsequent upgrades during installation. There are a large number of existing street lamp poles in cities, especially classic and structurally sound metal lamp poles, which have a much longer service life than the lamp itself. It is impossible to upgrade the existing street lamps to intelligent street lamps, and the old poles often need to be completely removed, new poles need to be erected, wiring needs to be done, and foundations need to be poured, resulting in a huge waste of resources.

[0018] Further, the bracket portion has side edge protruding portions on both sides, the side edge protruding portions have side plate insertion grooves, and the side plate insertion grooves can be inserted by the first side plate, the second side plate and the third side plate.

[0019] Further, the side plate insertion grooves have sealing strips.

[0020] Further, the first abutting unit and the second abutting unit are made of rubber material.

[0021] Thus, better sealing and waterproof effects are formed, and greater friction with the lamp pole is formed, which is beneficial to the installation and fixation of the multifunctional unit.

[0022] Further, the notch portion is U-shaped and has notches at both ends, the fixing unit comprises an embedded plate embedded in the notch portion and two protrusions fixedly connected with the embedded plate, the protrusions are embedded in the notches, and the protrusions are fixedly connected with the bracket portion by a third bolt at the protrusions.

[0023] Further, the fixing unit has L-shaped sealing gaskets on both sides.

[0024] Further, the notches have threaded holes matched with the third bolt.
