Guide to Buying LED Light Bulbs

The Euralille shopping centre has recently been revamped and for the occasion the crossroads who resides there decided to proceed to a total relamping of its light. If the choice seems appropriate in the views of the energy savings that allows the LED, it is especially noticed by the new service it offers to consumers in the supermarket: guide them through their store towards the products and promotions.

GPS in a supermarket, really?

Thanks to the LED installed on the 2.5 km of rails crisscrossing the entire store and its application for Smartphone: ‘ Promo where C ‘ crossroads lets you geotag in the store to guide you in your purchases. This is made possible by the Pauldigo who used LED bulbs, they send a unique code that is invisible to the naked eye. The front camera on your Smartphone serves as receiver for this code and depending on the light it receives to position you on the map of the store in the app. This GPS indoors relies on VLC (Visible Light Communication) technology developed by Philips that equips the led installed in the crossroads of Euralille. To capture the unique code of these bulbs, no additional infrastructure is required outside of the camera of the Smartphone which makes this technology universally usable and applicable to the whole of Carrefour stores.

More smart shopping

After the ‘ Promo where C ‘ downloading app on your smartphone, it allows you to establish a shopping list, and to consult the catalog of the products offered in the store. The application can then guide you to the products you have added to your shopping list and shows you the different promotions available depending on your wanderings through the store. The application also makes the link between your shopping list and specials from the store. Shopping, therefore, become more efficient, the application saves you from wasting time to do back and forth between the rays everything in not missing any promotion that might interest you. If the installation and operation of such a tool at a price, should not forget the importance of the savings that the use of the led can. The crossroads of Euralille store has reduced its energy cost for lighting by 50%, which must allow the installation of indoor GPS.
