A centralised DC power supply solution for LED lighting networks

Abstract

In the context of the FP7 CIP-ICT Programme, the EDISON project1 has the ambitious goal to introduce a new way of thinking lighting networks in buildings, for both retrofitting actions and new constructions. It proposes an innovative ICT-based solution for lighting infrastructure that aims to improve power efficiency, reduce CO2 emissions and encourage the use of small-scale renewable energy sources in public and private buildings. In particular, this paper focuses on a relevant aspect of the EDISON solution: the centralization of DC power supply in a LED lighting infrastructure. To this aim, a short analysis has been carried out in order to give evidence of the benefits arising from the application of this approach. Finally, preliminary results achieved in targeted Pilot actions, implemented in different European countries, have been reported.
