A connected outdoor lighting solution for smart city applications integrates an area, roadway or street lighting network into the ecosystem of the Internet of Things (IoT) and transforms lighting systems into smart, digital nodes that support data-driven operations and other smart city applications. As LED technology arrived at the forefront of lighting conversations, maximizing the energy savings and creating new value propositions from the solid state lighting (SSL) systems are becoming increasingly dependent on successful integration into the collaborative environment of cyber-physical systems.
Outdoor lighting for rural and urban infrastructure has evolved. Today, it is a convergence of hardware and software, distributed and centralized intelligence, operational technology (OT) and information technology (IT). An IoT based smart lighting solution employs a platform-based approach to create flexibility, scalability and interoperability for devices, systems, applications and networks to work together and create synergy. Through digital networking and IP-based communication, a framework is sketched to harmonize heterogeneous technologies and enable direct integration of intelligent street lighting systems into the growing world of IoT.
