%X We present the bidirectional power line communication system developed in parallel to an electronic board for driving and control of HID (high-intensity discharge) and LED (light-emitting diode) lamps. The communication system, developed to be applied in the sector of public illumination, is been designed to combine high efficiency and reliability with low production costs; it consists indeed of discrete cheap components. The communication system described in this paper implements the technique of transporting digital information over existing power lines, avoiding the issue of installing new cables. Digitized signals can use power line cables through the amplitude voltage and current modulation. The solution proposed is more advantageous compared to communication techniques currently on the market which are essentially two types, power line carrier (modem for high-voltage lines) or radio (zig-Bee transceiver). 1. Introduction Public lighting represents a primary service in the management of a city. It is indeed public safety guarantor, helps to improve the environment in which people live, and promotes city image through the enhancement of cultural heritage. Geographical extension of public lighting system makes it very difficult in order to ensure proper levels of efficiency, quality, reliability, and energy savings of the service by using traditional instruments. An intelligent electronic system for the control of both LED and HPS lamps for public lighting was designed. The feature of driving both types of lamps is unique for the realized system. This versatility is achieved through the implementation of a reconfigurable output capable of driving, by the user¡¯s choice, a LED or HPS lamp. Through an appropriate routine implemented in the firmware of the microcontroller, the system is capable of self-learning the type of lamp inserted in reconfigurable output. This feature allows to use the ballast in lighting systems that nowadays use the traditional discharge lamps and, primarily, will allow to keep the same ballast when discharge lamps will be replaced by the LED modules, in the near future in which the LED street lighting systems will be more affordable. The lighting implants are indeed characterized by a large number of hot spots scattered throughout the territory for which it is constantly necessary to monitor the operation and make its management. Particularly in urban areas, public lighting systems are greatly extended and widely distributed, and they contain a large number of control panels and, above all, light points. Therefore, it is
