Led-based Public Lighting System Reliability for a Reduced Impact on Environment and Energy Consumption

Light Emitting Diodes (LEDs) contain solid_state technology made in Silicon Valley using similar technologies that are used in the latest microprocessors. These solid_state devices have no moving parts, no fragile glass environments, no mercury, no toxic gasses, and no filament. There is nothing to break, rupture, shatter, leak, or contaminate. They are playing a significant role in energy saving policy; since private and public lighting are indicators of development in many countries. Developing policy must be envisaged in order to reduce impact on environment and energy consumption without sacrificing an important part of economic growth. This research outlines results of a campaign which has been conducting in the Town of Leporano, in the district of Taranto (Apulia Region, Italy) in cooperation with the local government. Different led system have been located on public posts.
