LEDVILLE Project : Traffic Roundabout LED Lighting System.:Technical and Social Approaches

We report a global study of a LED lighting system for an urban roundabout (LED-VILLE). A study of the photometric performances of the LED used has been performed in our laboratory. Furthermore, average illuminance, uniformity and luminance have been measured and compared to recommended data. Environmental footprints of this lighting system (carbon operation, life cycle analysis and light pollution) has been evaluated and compared to equivalent solution widely used to date. Finally, a social approach of the LED street lighting has been achieved: the visual perception felt by driving or walking users through the roundabout have been collected and analyzed.
