A public service cabinet includes a foundation support, a connection frame, and housing parts that delimit internal spaces for receiving electrical and/or communication/control equipment. The foundation support includes a first street mast module of which an upper end is configured to be connectable to a lower end of a second street mast module of a modular street mast. The connection frame is releasably connected to the first street mast module, and the housing parts extend to a height that lies above a height to which the first street mast module extends such that at least an upper portion of the first street mast module is surrounded by the housing parts. A removable first-type cover is provided that is configured to shield of an upper side of the cabinet including the upper end of the first street mast module.

A solar energy harvesting assembly having a unique attachment that can be arranged, mounted, moved and attached to new or existing structures. Solar rings are mounted on any vertical structure that may benefit from solar power using an aesthetically pleasing design that is resistant to wind load. The assembly does not require the need for pitch, azimuth or bearing measurements. The assembly is also capable of energy harvesting from reflected light below with the use of bifacial photovoltaic panels. The mounting design allows the solar energy harvest device to be installed on any vertical structure, including light poles, power poles, parking structures and other minimal load bearing structures. Further, the assembly can be attached to water towers, existing radio towers (guyed, monopole, stealth, self-supporting towers) all used to create vast amounts of unshaded vertical space for solar energy harvesting.

A street equipment assembly including a base and a plurality of poles. The poles can accommodate external devices, and the base is for receiving internal devices. The street equipment assembly allows sufficient electronic equipment to be installed on limited areas of roads, thereby in line with the needs of electronic equipment for smart urban development. The street equipment assembly in the present invention includes a connection pipe for guiding and connecting lines of the external and internal devices to the base. The connection pipe is further extended upwards to have its opening reach above top of the base to form a chimney structure. The chimney structure can prevent any liquid at the top of the base from entering the base through the opening of the connection pipe and can dissipate heat out of the base.

The present invention relates to a wind power generator for street light comprising: a post member installed vertically; a central fixed shaft member installed horizontally on an upper portion of the post member; a first blade member rotatably installed around the central fixed shaft member and including a first blade rotated by wind on one side thereof; a second blade member rotatably installed around the first blade member and including a second blade rotated by wind on one side thereof; a cone member having an inclined shape at a specific angle so that wind smoothly moves toward the first blade member and the second blade member, and a power generation module rotated by the first blade member and the second blade member to generate power. According to the present invention, the first blade member and the second blade member can supply sufficient torque required for the rotation of the power generation module and can increase power generation time by driving the power generation module with the double blades. In addition, it is possible to minimize the installation space and reduce the size of the wind power generator by installing the first rotating shaft and the second rotating shaft in a double layer structure.

Systems and methods for retrofitting existing light and other poles to provide additional functionality in the form of one or more electric vehicle charging stations. Exemplary systems include EV charging station bases that are interposable between an existing pole and its associated buried anchor base, and include one or more EV charging stations that may be powered through the existing electrical wiring of the pole to be retrofit. Exemplary systems may offer additional functionality in the form of optional advertising, Internet connectivity, and other features.
