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.

Business Model

Implementation

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

 

Market Overview

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

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

Driving Factors

EU Initiatives

EIP SCC Initiative on the Humble Lamppost: This initiative aims to develop an open, affordable component based city lighting solution that enables other smart city initiatives; delivered collaboratively between cities & industry to speed integrated valuable delivery:

Supporting Infrastructure

·   An existing fibre-optic backbone infrastructure eases the implementation of Smart Street Lighting as it ensures a high quality of the provided services.

Legal Requirements

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) 

EU Standards

  • DIN SPEC 91347 - Integrated multi-functional Humble Lamppost (imHLa): This standard was developed based on the EIP SCC marketplace Action Cluster on Integrated Infrastructures and published in March 2017. (Market Place of the EIP on Smart Cities and Communities, 2016)
  • DIN EN 40 - Lighting columns
  • ISO/IEC Directive Part 1 Supplement JTC 1:2016, Procedures specific to JTC 1

Use Cases

Smart Lighting in Strijp-S - Eindhoven
The project involved equipping light poles with multi-colour LEDs allowing interactive control of individual lights. This enables a variety of services such as: guiding people through different lighting, seasonal lighting programs for increased comfort, safety control via sound sensors.
Unidirectional functional lighting in Eckart
Unidirectional functional lighting has been installed on a walking path at a pond in Eckart. The special type of lights only shine towards the path and not on the pond to not disturb the local fauna.10 of the 30 poles are equipped with sensors that dim the light according to the usage of the path.
Smart Street Lighting in Tartu
The City of Tartu replaced 320 existing sodium lights in the city centre area of Tartu with energy efficient LED lighting. The new lighting and the  traffic and environmental sensors together with the wireless control units developed by Cityntel OU form a smart street lighting network.
Humble Lamppost - Integrated Multifunctional Smart Lamppost
Lamppost infrastructure and street lighting as a whole, are predestined to provide additional services and technologies to cities and their inhabitants. Street lighting is almost everywhere in a more regular pattern and it`s connected to electricity.
Remote controlled LED Street Lighting
Under the Smart Lighting measure of the Grow Smarter project, the goal is to demonstrate and test three different technologies for smart street lighting: remote, self-controlled and sensor-controlled LED lighting. In this Use Case the focus is on a remote controlled system connected to a CMS.
Intelligent Street Lighting in Ludwigsburg
As part of the "Living LaB" innovation network in Ludwigsburg, this use case is an example of how cities can become "smarter" in the future.
Smart interactive floorlight for walking and running in Eckart
To encourage walkers, joggers and runners interactive lights are embedded in a footway around two ponds in Eckart.
Smart lamp posts
Milan is exploring how a range of sensors and services can be added to lamp posts to transform them into a smart infrastructure for the city, demonstrating how smart technology can add value to people’s lives. The goal was to improve the efficiency of energy use in public lighting.
