Smart streetlights enable the reduction of running expenses associated with public lighting by delivering several value-added services to cities and citizens.
The solution allows the dynamic adaption of the brightness of streetlights according to the season-dependent day and night cycle duration or even to a combination of this and the noise level. A good lighting system increases both actual and perceived security. Furthermore, directed light may improve the well-being of residents. An underlying connectivity backbone connects the poles (i.e. fibre-optic backbone) and serves to deliver digital services via integrated street lights.
Within this solution, the lighting poles can be used to provide other functionalities (i.e. Intelligent and Connected Public Space – Wi-Fi, navigation aids for visually impaired people or displays) through the attachment of additional sensors or signalling devices.
Average implementation time: 1 - 2 years
Initial investment amount: around 2,000,000 Euro for a system with 400 light poles including groundwork and WiFi capabilities
The global market for smart lighting is expected to reach 9.47 Billion USD by 2022. (markets and markets, 2017) By implementing this solution, various marketable benefits can be achieved. These are for example energy savings, increased lifetime, increased security and increasing flexibility. Within the implementation of a smart lighting system, other applications can be integrated. Examples of these applications are traffic monitoring, smart parking, charging of electric vehicles and environmental monitoring. (Castro et al., 2013)
Cost savings due to the implementation of a smart lighting system have two different reasons. One reason is the energy savings whereas another reason is operational savings. Due to a calculation of the silver spring networks for 50,000 smart street lights and a period of 20 years estimates the overall savings with $38.9 Mio. Possible reasons for both times of savings are the following:
- Energy savings: Low wattage, dimming, reduced burn time
- Operational savings: Long lifetimes, remote monitoring and management, automatic outage detection, proactive maintenance

· An existing fibre-optic backbone infrastructure eases the implementation of Smart Street Lighting as it ensures a high quality of the provided services.
Smart lighting is affected by the regulations concerning energy savings, like the following:
- Directive 2009/28/EC: includes national binding targets for EU countries. These suppose that by 2020, at least 20% of EU’s final energy consumption should come from regenerative energy system. Further, each Member State is required to reach a 10 % share of biofuels in the overall use of transport fuels by 2020 (European Parliament, 2009)
- Directive 2006/32/EC: regulates the use of smart meters to increase energy efficiency and better inform customers about their consumption (European Parliament, 2009)
But smart lighting is also influenced by data security regulations as data is collected to optimise the solution.
- Directive 95/46/EC protection of individuals concerning the processing of personal data and on the free movement of such data (European Parliament, 2009)
A European Parliament and Council Directive on this issue (2009/125/EC) outline eco-design requirements for energy using products, focusing on energy consumption during the entire product lifecycle including production, transport, scrapping and recycling. Therefore, most municipalities are supportive in the implementation of smart lighting or even implement them themselves. (European Expertise Center, 2013)
