Lighting in the building: A DC Smart Grid

The paper illustrates the idea developed in a European PSP-ICT project, named EDISON, proposing advanced ICT solutions for Solid State Lamps (SSLs) control and energy saving actions. The EDISON System is based on very efficient DC power supply modules feeding Light Emitting Diode (LED) lamps - The proposed solution permits to increase the energy saving resulting from LED lamps application, and to implement a control network on the existing lighting infrastructure, without additional cabling. The smart components are very simple commercial products primarily devoted to the light control and dimming. This paper presents the architecture of the proposed system, its effectiveness in saving energy and the possibility to extend the control to services other than lighting. The EDISON solution has been implemented in more than 20 Pilots, in different countries in Europe (Italy, UK, Belgium). All the pilots are running and the results demonstrate the high efficiency of the proposed technical approach. (http://www.project-edison.eu).
