Smart lighting has undergone a significant transformation, evolving from a simple tool for energy conservation into a platform for urban innovation.
Over the past two decades, the first generation of smart lighting aimed at achieving the utmost energy efficiency by replacing traditional streetlamps with LEDs and integrating remote control systems. This initial stage offered clear economic benefits by reducing power consumption and maintenance costs, while also supporting sustainability goals by lowering greenhouse gas emissions.
“Today, we are firmly in the second generation, where the role of smart lighting extends far beyond illumination and mere savings”, says Carlo Bernocco, Head of Business and Customer Success at Paradox Engineering. “Thoughtfully designed systems are now recognized for their impact on livability, public security, and urban attractiveness, with lighting supporting the transformation of public spaces, the beautification of parks and monuments, and even crime prevention and safety. This shift positions smart lighting as an integral component of a city’s broader strategy for urban development“.
The next wave of smart lighting is being shaped by advancements that favor heterogeneous and more flexible network infrastructures. Innovations such as hybrid and cellular nodes are proving to be transformative as they enable gateway-less, plug-and-play installations, which significantly minimize deployment complexity and ongoing maintenance efforts. These solutions are key to ensuring future-proof scalability and adaptability as urban needs change.
However, the most disruptive advancement lies in interoperability. The progress of industry-standard frameworks, such as OMA based on the uCIFI data model, is introducing an unprecedented level of openness with the possibility of integrating diverse devices and applications over the same network.
Cybersecurity should also be considered. As smart lighting evolves into a multifunctional network platform, it must incorporate robust cybersecurity measures to protect against potential threats possibly compromising not just the lights, but also critical urban data and other public services. Cities must prioritize secure-by-design technologies and rely on skilled partners to ensure an adequate defence along the entire lifecycle of devices, applications, and network components.
As cities increasingly embrace the Internet of Things, smart lighting becomes central to enabling data-driven decision-making, enhancing citizen services, and driving sustainability efforts. Urban leaders must prepare for a future where street lighting goes beyond illumination to become a fully integrated part of the city’s digital ecosystem.
