Smart LED lighting with Interact remote management in Roztoky has provided safer streets, lower costs, and a more environmentally friendly approach.
The city of Roztoky modernized its public lighting with Signify LED technology
"The project delivered 74% energy savings, annual savings of CZK 200,000, and improved safety. In addition, thanks to the Interact City system, we have control over when and where lighting is needed. "
- Ing. Ivan Goll, Secretary of the City of Roztoky
Customer Challenge
The original public lighting in Roztoky was outdated, had high energy consumption, and produced excessive light pollution, increasing costs and negatively affecting the environment and residents’ well-being.
The city was looking for a solution aligned with modern standards and environmental criteria, respecting the appearance of public space while enabling future integration of smart systems.
The project had to be implemented quickly without significant disruption, ensuring precise planning, cost calculation, and flexible coordination with suppliers.
Solution
For the modernization, Philips DigiStreet, CitySoul, ClassicStreet, and Villa LED luminaires were used, predominantly DigiStreet (BGP76x) with optical efficiency up to 90%, directing light downward and equipped with shields to reduce light spill.
Warm white light was used: 2200 K for parks and quiet zones, 2700 K for main routes and side streets, reducing light pollution and ensuring comfortable color perception. The Interact City system enabled remote control, dimming, predictive maintenance, and rapid response to faults.
"The city can now flexibly respond to rising energy prices, for example by introducing dimming regimes or adjusting switching times. Lighting is operated only when and where it is actually needed."
Ing. Ivan Goll, Secretary of the City of Roztoky
Energy savings
Reduction of total lighting system power consumption by 41% thanks to the switch from discharge lamps to OptiVision LED technology.
Annual cost savings
Approximately EUR 8.000 saved on energy annually (at 0,089 EUR/kWh and 4.100 hours/year).
Reduced light disturbance to surroundings
Asymmetric optics with integrated shields and light spill control helped reduce unwanted light outside the sports facility.
Efficient operation
Lighting is used only when and where needed. Ability to adjust light levels based on activity type improved operational efficiency.
Smart control
The Dynalite control system enabled easy operation, preset lighting scenes, and dimming and instant restart in case of a power outage.
Ready for the future
The modern LED infrastructure with intelligent controls is scalable and ready to meet future technological requirements of the sport facility
