Definition: Smart lighting is a system initially designed to increase energy efficiency by adapting light intensity according to various parameters (natural light, occupancy, etc.).
Progress in technology is considerably increasing the intelligence of a lighting system. No longer merely adapted or adequately used, it becomes capable of communicating with its environment, drastically changing traditional uses and paving the way to many new ones.
Smart lighting thus becomes a key tool in smart city development, a means of giving areas complete digital independence, tantamount in principle to creating efficient, interconnected cities where citizens live as one with their environment.
The world’s biggest network:
Worldwide, there are over four billion public lamps, mostly consisting of high-intensity bulbs using mercury and other toxic substances.
There are plans to pool this lighting network, territory by territory, by replacing current equipment with lower consumption connected sensors. Each lamp would be reconfigured as a node in a local network, constantly recording and sharing data with other local networks.
This prospect is made possible by the lowering cost of LEDs, by connecting each system on the net and involving video technologies to retrieve information (video).
With Li-Fi, it would be possible to create an overlayer different to the internet and fully controlled by local authorities, to meet the requirements of smart cities and unload traditional data networks.
Lighting becomes an intra-city network for exchanging geo-located, service or lifestyle information.
To make Li-Fi free and accessible, alongside its operational missions, SLA has set the goal of designing and providing users with a freeware Li-Fi reader for fast, widespread use of Li-Fi and system inter-connectability.
