Siedlce City
Case Study Siedlce Tunnel
Comprehensive modernization of tunnel and external lighting on the extension of Kiliński Street in Siedlce. The project involved supplying and installing luminaires adapted to various tunnel zones and demanding external conditions, ensuring comfort and safety for drivers.
As part of the project “Construction of a tunnel under the PKP tracks on the extension of Kiliński Street to Składowa Street in Siedlce,” Luxon LED, in collaboration with Warbud, implemented a comprehensive lighting system for the tunnel and its surroundings. The tunnel, over 150 meters long, required the use of tunnel luminaires, vandal-resistant lighting, and emergency and external lighting. The challenge was to ensure adequate light intensity depending on the zone (entry, transit, and exit) while meeting lighting standards to provide comfort and safety for drivers during transit.
Tunnel and Surroundings
Road Infrastructure
Tunnel and vandal-resistant luminaires, 24-hour lighting, luminous flux measurement over time
Challenges
Appropriate lighting for different tunnel zones
High resistance of luminaires to vandalism
24-hour operation of luminaires with luminous flux drop measurement
Quick and efficient implementation according to project assumptions
The tunnel, over 150 meters long and located under the PKP tracks, required the delivery of specialized tunnel, vandal-resistant, emergency, and external luminaires. The client expected rapid implementation while considering all project assumptions. Each tunnel zone required different light intensities, crucial for driver comfort and safety. Additionally, luminaires had to operate 24/7, making the measurement of luminous flux drop during 24-hour operation essential.

Lighting Concept
Four types of luminaires were selected for the project, including tunnel, vandal-resistant, emergency, and external luminaires. Skylight LED was adapted for tunnel conditions by modifying the optics and a power of 41 W, avoiding the need for additional control systems and power reduction. All luminaires ensured appropriate light intensity in the respective tunnel zones (entry, transit, and exit), guaranteeing driving comfort and safety around the clock.
Skylight LED
Tunnel luminaire with a power of 41 W, adapted to industrial and tunnel conditions. With special optics, it provides appropriate light distribution in the entry, transit, and exit zones.
Vandal-resistant luminaires:
Used in areas exposed to mechanical damage, ensuring durability and resistance to vandalism.
Emergency luminaires:
Installed to ensure safety in emergencies, they operate continuously, regardless of power supply.
Scope of Cooperation
We started the project with a detailed inventory and audit of the tunnel and its surroundings. Based on the calculation results, we designed a lighting system that met all project requirements and road lighting standards. A key element was adapting luminaires to specific tunnel conditions, ensuring vandal resistance and 24-hour operation, which required precise measurements of luminous flux drop over prolonged use.
During installation, we ensured rapid delivery of tunnel and external luminaires, while ensuring full compliance with project assumptions. By using Skylight LED luminaires with a power of 41 W, we avoided the need for an additional control system, speeding up implementation and reducing operational costs.
Implementation Results:
