Aix-les-Bains now has an innovative public lighting system that combines LED units with presence detectors on city streets. Launched in September 2014, this experiment is coordinated by the CSTB in partnership with the Lumière cluster as part of the Rhône-Alpes DEDRA (Sustainable Public Lighting Demonstrator program). Its aim is to improve the energy performance of public lighting systems, while offering users lighting environments that perfectly meet their needs.
As night falls, the Place du Cardinal Garonne in the center of Aix-les-Bains is illuminated by eight LED lighting units supplied by Soitec and controlled by a system designed and manufactured by BH Technologies in conjunction with HIKOB. What makes these facilities particularly original is that they adjust the lighting level to the presence of users (pedestrians, joggers, cyclists or drivers) and how they travel through space. The data collected is transmitted wirelessly to the radio frequency control system. The result is an almost instantaneous transition from minimum security lighting to more intense street lighting. This experiment will make it possible to assess several criteria regarding the gains offered by upgrading public lighting equipment to LED technology combined with remote detection.
