The following technological alternatives impacting both energy efficiency and management were evaluated for the street lighting system, in full compliance with applicable regulations.

The advantages achievable with LED technology combines both the positive aspects of a very low environmental impact, thanks to its energy efficiency and absence of pollutants, and those of excellent lighting and color rendering that can improve the comfort and safety of road users. For these reasons, the design proposal is to replace all current lamps with state-of-the-art LED light sources. There are currently 16186 light sources installed consisting largely of lamps with SAP sources, an inefficient technology that has been largely superseded by new, higher-efficiency systems.

However, the remaining roadside luminaires are found to be old and technologically obsolete, with low performance values, or with absent or inadequate optics, some lacking a closing screen or with an open, damaged or degraded cup, insufficient degree of protection, and inadequate from the point of view of energy conservation.

To implement the modification of the light source, it is planned to act through the complete replacement of the existing luminaire and with LED re-lamping intervention, preserving the structure and envelope of the existing luminaire. Through LED KITS, it is possible to perform a technological and energy-saving modernization of existing art lanterns while keeping the same fixture alive without replacing it entirely.

It was deemed appropriate to replace all street-type fixtures with new state-of-the-art “DigiStreet”-“Unistreet Performer” LED fixtures, and street furniture fixtures with “ClassicStreet” brand Philips or equivalent.

Safety in the various urban areas affected by the interventions and continuity of service, will be ensured through the installation of a remote control and remote management system for the street lighting network.


Electrical parameters will be monitored at the height of the ignition switchboard, where a local controller will be placed that can transmit the collected data to the computer station and remotely by emergency responders via mobile terminals. An Algorab remote control system for dynamic lighting will be used for the lighting control system.

The proposed system is called P5, a public lighting management platform that combines the advantages of a modern remote control system for individual lighting points with the exceptional integration possibilities arising from the use of communication technologies typical of WSNs (Wireless Sensor Networks).

The Wireless Sensor Network (WSN) involves the use of electronic devices (sensors and actuators) that are able to work in a distributed manner and share information through the same communication channel. WSN involves two requirements: city sensing from the terminal nodes and a wireless network infrastructure to carry the information.

This is the context for Algorab’s P5 system, which stems from the intuition of exploiting lighting points as supports for the WSN network. The Algorab devices installed on the light fixtures (P5) allow both to drive the lighting according to local or remote logic and to perform WSN router functions with the other control units.

Radio communication between Algorab devices enables the creation of the WSN infrastructure that is used for both remote lighting telecontrol and city sensing activities and smart city services.
