Explore our high-efficiency LED luminaires, custom-engineered to withstand severe conditions inside highway, railway, and mining tunnels, fully aligned with European standards.
Bulgaria plays a crucial role in Europe’s transport network, serving as a gateway between Central Europe and the Middle East. Key routes like the Hemus Highway (A2), Struma Highway (A3), and Trakia Highway (A1) feature extensive tunnel structures passing through the Balkan and Rila mountain ranges. Among these, the newly constructed Zheleznitsa Tunnel—the longest road tunnel in Bulgaria—highlights the country's commitment to modernizing its transport infrastructure.
Operating conditions in Bulgaria present distinct challenges for infrastructure engineering. Tunnels experience high humidity, extreme seasonal temperature swings (ranging from -25°C in winter to +40°C in summer), and continuous exposure to exhaust gases, soot, and corrosive de-icing chemicals. Delivering high-quality illumination in these environments is essential for driver safety and structural durability.
As a specialized supplier and exporter, Jiangsu Lukas Lighting Co., Ltd. provides advanced luminaires designed to meet these challenges. Our systems comply with the European Union’s EN 13201 road lighting standards and the minimum safety requirements of Directive 2004/54/EC for tunnels in the Trans-European Road Network (TEN-T).
Globally, the transition to smart cities demands intelligent tunnel lighting systems that adapt dynamically to ambient light levels. Traditional, fixed-output high-pressure sodium (HPS) lamps are rapidly being replaced by dimmable LED systems featuring real-time diagnostic capabilities.
In Bulgaria, local municipalities and the Road Infrastructure Agency (RIA) prioritize energy-saving initiatives backed by European regional development funds. These projects mandate strict compliance with optical precision standards to minimize glare, ensure uniform light distribution, and secure long-term reliability. We integrate high-efficiency optics and specialized light distributions to meet Bulgaria's safety guidelines, helping to reduce traffic accident rates while optimizing public spending.
Our systems utilize advanced luminance meters (L20 sensors) mounted at tunnel portals to monitor ambient outdoor brightness. The control system automatically dims the interior LED array, minimizing glare and eye strain for drivers entering the tunnel.
Engineered with high-grade ADC12 aluminum die-cast housings and tempered glass lenses. The luminaires feature a C5-M level anti-corrosion coating to resist salt, moisture, and automotive exhaust buildup common in mountain passes.
From initial DIALux lighting design simulations to commissioning, we collaborate closely with local Bulgarian contractors. We ensure every lighting installation complies with national safety standards and municipal grid requirements.

Find expert answers to common technical questions regarding standards, installation, and performance of tunnel lighting solutions in Europe and Bulgaria.
In Bulgaria, highway tunnel projects must comply with the European Standard EN 13201, which defines road lighting classes, and CEN/TR 12101-1, which covers tunnel lighting design rules. Additionally, compliance with Directive 2004/54/EC is required for safety measures on tunnels within the Trans-European Road Network (TEN-T).
The "Black Hole Effect" occurs when a driver's eyes fail to adapt quickly enough to the dark entrance of a tunnel when arriving from a bright exterior. To mitigate this, our high-power LED floodlights are installed in the Access and Threshold zones to match the external luminance and ensure safe entry.
Luminaires should have a minimum of an IP66 rating, with IP67 or IP69K preferred, to withstand regular high-pressure water cleaning. For corrosion protection, fixtures should feature C5-M grade coatings to resist vehicle emissions, de-icing salts, and high moisture levels.
We provide full technical support, including DIALux lighting simulations, electrical loading layouts, and localized support through our engineering team. We assist contractors during the bidding process, design phases, and installation phase to ensure compliance with Bulgarian infrastructure requirements.
Yes, several of our specialized fixtures, such as the IP66 Waterproof Tri-Proof Lighting Series, include options for built-in emergency driver packs. These systems deliver up to 3 hours of operation during a main power failure, complying with European safety and evacuation guidelines.
