Royal Philips, the global leader in lighting, announces today the world’s first major install of its connected lighting system with LED-based indoor positioning for Carrefour, the leading retailer in Europe and the third-largest in the world. The newly refurbished Carrefour hypermarket in Lille, France has replaced its previous fluorescent lighting with 2.5 kilometers of energy efficient Philips LED lighting that uses light to transmit a location signal to a shopper’s smartphone, triggering an app to provide location-based services.
