Electronic board for driving of HID and LED lamps with auxiliary power supply from solar panel and presence detector

This paper describes an intelligent electronic system for the control of LED and SAP lamps for public lighting. The lighting system is designed to be applied in rural areas where there isn´t public voltage electricity. Each lighting point, in fact, has a system to convert solar energy into continuous voltage by photovoltaic panels. The communication between the electrical cabinet and the individual lighting point is through the power line. In order to ensure a high energy savings, in addition, the intensity of the luminous flux produced by the single lighting points is maintained at 50% of the nominal value. Instead, it is increased to 100% in case of vehicles in transit in the area illuminated by lighting point, vehicle or pedestrians detected using appropriate presence detector.
