Streetlight networks are strategic assets for cities. Streetlights illuminate the roads we drive on, the pedestrian paths we walk along and the public areas where we gather. It provides us with safe roads, safer public areas and enhanced security in our homes, businesses and city centres.

However the number of streetlights in a city and their wide geographic distribution make them difficult and expensive to operate: Streetlights are a major source of energy consumption (In some Municipalities where SELC have installed Central Monitoring Systems, the streetlights accounted for in excess of 35% of a Municipalities annual energy budget!). Other factors including the increasing cost of electricity, the need for lamp replacements on average every three years, the provision of manpower and service trucks for onsite maintenance operations and outdated luminaires requiring retrofits- all contribute to the need for proper monitoring and control technologies to be deployed in order to limit the downside of such factors on the provision of an effective and efficient street light network. Street light networks also add to carbon dioxide (CO², the principal “greenhouse gas”) emissions or nuclear dust from the production of electricity required to power the system.

There are 2 ways to monitor and to control street light infrastructure:

  • Using the underground power lines underneath street poles as fixed lines to monitor, to communicate with and to control individual streetlights – The SELC Candelon CMS
  • Using a wireless photocell fitted to each street light which monitors, communicates and controls each street light individually - The SELC Wireless CMS 

Key benefits

Reduced Power Consumption

Reduced power consumption due to improved control of each individual street light

Reduced CO² emissions

With reduced power consumption comes reduced CO² emissions – With built in energy metering, the CMS system can accurately translate energy savings into CO² credits.

Ease of Maintenance & reduced maintenance costs

Ease of maintenance due to accurate monitoring of lamp conditions and proactive scheduling of planned maintenance activities as the SELC Central Monitoring Systems accurately predicts lamp failures. (Includes lamp end of life shutdown and reporting failures)

Open platform for monitoring and dimming

SELC Central Monitoring Systems are deployed using an open platform technology allowing the end user to decide on how they would prefer to monitor the street lights under CMS control. Our customers come first and we want them to have the choice as to how they monitor their street lights and control light output via various (location dependent) dimming regimes.

Advantages of using a SELC CMS to monitor and to control your street lights

  • Save more than  50% Energy and associated CO² Emissions: individual and grouped lamp dimming (step-less dimming at any level, any time)
  • Enhance Maintenance Operation: automatic identification of failures, real-time control of any individual lamp, increase lamp lifetime, reduce onsite maintenance costs, remove night patrols, automatic generation of alarms and notification to operations managers and crews to optimise their maintenance schedules
  • Enhance the quality of your lighting provision on the streets – The streets are lit to the right level BUT only at the right time e.g. when traffic/pedestrian loads are less dense on the streets, the street lights should dim to a lower level!
  • Open platform
  • Increase security and safety in the streets and on the roads
  • Our wireless CMS has built in redundancy so if ever the GPRS/Mobile network goes down then the photocell will always act as the street light controller – a proven lifetime of 28 years without failure in the field so you can have confidence that your street lights will always be available regardless of the state of the GPRS network.
  • Exchange valuable data with various Network Maintenance Tools, Demand/Response systems and Geographical Information Systems

Case Study - Oslo, Norway

10,000 intelligent street lights eliminated 1,440 tons of CO2 emissions from the Norwegian capital and reduced energy usage by 62.

“with 6,500 electronic [SMART] ballasts from SELC Ireland Ltd already installed and the balance of 49,000 to be installed over the next 3 years, energy consumption and maintenance have been reduced considerably” 2006
