Royal Philips 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 kilometres 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.

The Philips system enables Carrefour to provide new services to its customers, such as helping shoppers to navigate and find promotions across the 7,800 square metre shop floor. In addition, the LED lighting will reduce by 50% the total lighting-based electricity consumption of the hypermarket.

Philips indoor positioning system consists of LED fixtures, a cloud based location database and a Philips software development kit upon which customers can build their mobile interaction platform. The system in operation at the Carrefour hypermarket in Lille comprises 800 linear LED fixtures that use patented Philips VLC (Visible Light Communication) technology to transmit a unique code through light that is undetectable to the human eye but can be simply detected with a smartphone camera, without the need for any additional accessories. As part of the installation, Philips software and cloud-based location database has been integrated into Carrefour’s mobile app. The “Promo C’ou” mobile app was created by Think&Go and can be downloaded from today from Apple’s App Store in France.
