For the first time ever in the world, shoppers at the Carrefour Euralille hypermarket in Lille now have a guiding light: but we’re not talking about a guru in the fruit and veg aisle, but a location-based LED system developed by Philips.
Philips has just finished installing 2.5 kilometres of LED lighting in a newly-renovated hypermarket. In addition to lighting the store, the lighting fixtures act as a positioning grid which points customers to special offers on in the shop.
With the “Promo C-où” app, available for free from App Store, customers can, with just a few clicks, make a shopping list including any special offers on. Then, once they get to the store, the app helps them locate the products chosen. Marlène Tissé, Retail Marketing Manager for Philips, explains:
“Our technology uses VLC (Visible Light Communication). Each diode emits a unique code that is detected by all devices with a camera, without needing any specific accessories.”
It works like an indoor positioning system: the LEDs send a one-way signal to smartphones with the dedicated app. To do so, the diodes switch off and on very quickly to change the light in a way that is invisible to the human eye but can be detected by a smartphone’s camera.
A BRILLIANT innovation
For Carrefour, VLC is an opportunity to offer clients location-based services to ensure a more interactive, personalised shopping experience on the one hand, whilst making substantial energy savings thanks to the LED – a guaranteed return on investment.
