Connected street lighting system helps Cardiff go ‘smart’ and ‘green’

City council’s project with Philips Lighting aims to reduce city’s carbon footprint by reducing energy used for public lighting by 60%


The City of Cardiff has taken major step to become a smart city and reduce its carbon footprint by installing more than 14,000 connected LED streetlights.

The system aims to reduce electricity for lighting by 60%, saving more than £750k per year while supporting the safety and security of citizens.

Project follows public consultation and offers digital infrastructure for future smart city services.

The LED streetlights will help reduce the city’s carbon footprint through substantial energy savings and increased operational efficiencies.

The network of street lights, monitored and controlled remotely by Philips CityTouch, will provide Cardiff with a scalable digital infrastructure that may be upgraded to provide additional smart city services.

Each light point is being connected wirelessly to Philips CityTouch, which willmonitor, control and manage the entire lighting network. This enables lighting managers to dim or increase the brightness of street lights to meet the needs of the city at any given moment. For example, brightness levels can be increased near busy crossings or to help emergency services.

The new system also offers a lighting asset management capability that can help lighting managers monitor network performance in near real time, pinpoint faults and dispatch crews to precise locations, eliminating the need for night crews to drive around looking for faulty lights.

Switching to connected LED lighting is expected to reduce electricity used for lighting by 60% with estimated savings for the council of more than £750k per year. 

Streetlights have also the option to be equipped with sensors to monitor traffic flow, noise levels, air pollution, etc in future.

Chris Jones, lead electrical officer at Cardiff City Council said, “Philips Lighting has given us an infrastructure that will grow with our needs and provide quality light to make our citizens feel safer. With continual monitoring, we can now respond instantly – such as increasing light levels at peak times outside schools and hospitals”

Jacques Letzelter, head of public lighting for Philips Lighting, said, “Our connected street lighting will contribute to a safer environment for the citizens of Cardiff and will enable the city to achieve savings in energy and enjoy operational efficiencies. It provides a scalable and flexible digital infrastructure which gives the city options for the future, such as inputting data into smart city dashboards or adding sensors that could, for example, monitor noise or traffic”.
