Innovative system with occupancy sensors and point-to-point control
Via XX Settembre in Milan is characterized by a "tripartition" of the road: in the center there is the presence of the two main roadways, lined with car parks and traffic islands for bikes; outwardly on each side there is a carriageway driveway, an additional row of car parks and a pedestrian sidewalk.
The bushy trees present on the median represent further added value of the area, featured by extensive green spaces in the urban environment.
The lighting project has created a space nocturnal totally renovated, a place where human relationships can realize a continuity of expression during the evening hours.
The upgrading plant and lighting system of the entire road network has been then obtained by the adoption of the latest technology with LED light sources.
The new plant has been realized with the installation of supports and high performance decorative luminaires FIVEP LINK FLAT model, suitable to the aesthetic features of the street, with specific optical (asymmetric road and pedestrian), fully shielded, able to convey the luminous flux only where necessary.
All lighting fixtures were equipped with the system of remote point-to-point power line carrier, which allows the dimming at night, range Opera Revetec.
In particular they have been installed within the lighting fixtures, power line carrier transceivers (LPL) which on one side allow to adjust the power consumption for each light point and the other shows the information of the operation to the electrical power supply connected via GPRS modem to the A2A Control Centre, which is running the remote management software Maestro.
The expected products for the illumination of bicycle paths are connected to a system for presence detection that governs their power to the passage of pedestrians and bikers thus ensuring significant savings in energy consumption.
The solutions adopted have allowed the achievement of well-defined objectives:
- Maximum visual comfort
- Respect of minimum requirements, according to the lighting classifications;
- Restraint of "light pollution" thanks to a precise study of optics as required by the applicable Regional Law No. 17 of 03/27/00
- Reduction of direct glare and control of the gradients of luminance for each visual scene, be it micro or macro;
- Coordinated designing throughout the area, thanks to flexible switching
- Optimization of energy consumption in relation to the real needs of the user, thanks to the intelligent luminous flux control and power consumption.
