Retrofit that saves energy and architecture
The lighting at Špilberk Castle has undergone a major renovation by DATmoLUX a.s., using IQRF® wireless mesh technology.
The new IQRF® wireless controllers are discreetly hidden inside the historic light fixtures, fully respecting the cultural heritage while bringing all the benefits of modern infrastructure. Reliable wireless control requires no intervention in listed buildings or excavation work in historic environments.
As part of the project, the original discharge lamps were replaced with new LED luminaires equipped with IQRF® wireless modules. While the number of reflectors increased from 70 to 96, the total power consumption decreased by 44% (from 18.45 kW to 12.79 kW).
The installation was completely non-invasive – the luminaires remained in their original holders, and IQRF ensured connectivity without a single meter of new cabling. The monument authority had no objections to the solution.
The modern control system was implemented in full compliance with monument protection, without compromising aesthetics or functionality. At the same time, the system was seamlessly connected to the city's central control system (CMS), from where it is now easy to control dimming, various thematic scenarios, and operation monitoring.
Benefits in numbers
Return on investment in 4 years – the total cost of the lighting renovation was covered by savings on energy, mobile lighting rentals, and service.
Annual savings of CZK 1 million – thanks to the city's own RGBW system, it is no longer necessary to order mobile lighting for cultural events or state visits.
Installation within 4 months – the public tender was announced in November, the hardware was deployed within 3 months, and live operation began during the fourth month.
Significant reduction in faults – most potential faults are now detected automatically by the system.
Aesthetic effect – the new lighting scene has received positive feedback from tourists and the media. The visual impression, uniformity, and color options have taken the overall impact of the monument to a new level.
Why IQRF?
IQRF® wireless technology is a Czech solution that has found application in large lighting networks around the world. In the field of public lighting, it offers:
✓ Secure encrypted operation without license fees
✓ Quick, non-invasive installation
✓ Connectivity to a central control system, options for various lighting scenarios
✓ Resistance to interference and extreme conditions
✓ Possibility of expansion with additional elements such as sensors, charging stations, or parking systems
IQRF® makes it easy and quick to add smart connectivity to even historic lighting fixtures – without interfering with the design. For cities and monument owners, this means savings, maintenance prediction, and long-term sustainability.
Central management saves costs and opens up new possibilities
The modern Central Management System (CMS) allows public lighting and other infrastructure to be managed from a single location. Thanks to IQRF®, it is easy to connect luminaires in heritage areas, which then gain the same functions as the latest city lamps – from remote dimming to analytics and predictive service.
Conclusion
The Špilberk Castle lighting project shows that technology and cultural heritage do not have to be at odds with each other. On the contrary, a smart, wireless solution can protect history while bringing significant savings, comfort, and modern management to cities.
IQRF® illuminates medieval castles and historic and modern city centers, while the technology hidden inside ensures invisible, reliable management.
