Our top-tier architectural and safety tunnel luminaires designed for entry zones, transition paths, and continuous interior lighting.
Vietnam's rapid urbanisation and active development of economic corridors demand robust road network expansions. According to the National Expressway Development Plan, the country aims to build over 9,000 kilometers of expressways by 2050, alongside massive urban metro networks in Hanoi and Ho Chi Minh City.
Vietnam's extreme weather profile includes average relative humidity exceeding 85%, torrential monsoon seasons, and high ambient temperatures. Tunnel lighting must resist moisture ingress, thermal cycling, and galvanic corrosion from salt spray in coastal zones.
Vietnamese traffic standards (TCVN 259:2001 & QCVN 07-9:2016/BXD) stipulate that highway tunnels must prevent the "black hole effect" at entry portals. Transition zones need powerful adaptive dimming controls to adjust luminaire output dynamically according to exterior daylight intensity.
Smart lighting systems connected via LoRaWAN, PLC, or DALI protocols are mandatory for modern Vietnamese highway tunnels (e.g., North-South Expressway). Energy reduction requirements demand up to 50% efficiency gains compared to legacy HPS luminaires.
Modern tunnel lighting is a complex science of luminance transition. To prevent optical shock for drivers, a tunnel is divided into four zones: Threshold Zone, Transition Zone, Interior Zone, and Exit Zone. Lukas Lighting designs luminaires with specific asymmetric optics for each zone.

Jiangsu Lukas Lighting Co., Ltd. was established in 1998 with a strong commitment to innovation, quality, and sustainability in the outdoor lighting industry. Over more than two decades of development, the company has grown into a professional manufacturer specializing in intelligent and energy-efficient street lighting solutions.
Located in Jiangsu, China, our modern production base covers an area of approximately 11,000 square meters. The facility is equipped with advanced manufacturing technologies and operated by a team of experienced engineers and skilled technicians. This ensures strict quality control, precision manufacturing, and efficient large-scale production capabilities.
With efficient production lines and advanced automation, we are capable of handling both large-volume orders and complex customized projects with precision and speed.
We have established a comprehensive quality control system and have passed ISO9001 international certification. In addition, we have obtained multiple patents in lighting structure design and optical technology.
We provide fully integrated services including product design, mold development, prototype testing, mass production, and logistics support—eliminating intermediate links and ensuring faster delivery and better cost efficiency.
Every tunnel lighting fixture undergoes rigorous material processing, component assembly, and system stress testing to guarantee long-term field stability.
Developing light infrastructures for enclosed spaces like expressways and subways requires extreme engineering rigor. Unlike standard street poles, tunnel luminaires are mounted on low ceilings or high walls, subjected to constant exhaust emissions containing particulate matter, carbon residues, and sulphur oxides. Combined with humidity, these particulates form acidic deposits that eat away normal aluminum alloys.
When a driver approaches a tunnel entry point on a bright day in Vietnam (where external luminance can exceed 100,000 lux), their eyes cannot adapt to the sudden darkness of the tunnel interior fast enough. The tunnel appears as a solid black wall, posing immense risk of collision. Lukas Lighting designs customized high-power floodlights for the portal threshold zones to produce up to 5,000cd/m² luminance levels. Our intelligent sensors measure the ambient light outside and step-adjust internal lighting dynamically via PLC (Power Line Carrier) controls, saving significant operational energy during dark or rainy days while ensuring visual comfort during high noon.
Vietnam's coastal topography implies that many highway tunnels (such as those along the Central Coast and rural corridors) are exposed to marine salinity. Furthermore, the exhaust gases within unventilated or semi-ventilated tunnels trigger galvanic corrosion when moisture bridges the aluminum heatsink with steel mounts. Lukas utilizes marine-grade die-cast aluminum alloys treated with electrophoresis and powder coat finishes certified to meet C4 or C5 class anti-corrosion requirements.
High continuous operation in confined spaces generates immense heat. Our structural engineers design specialized thermal convection fins that prevent dirt accumulation while keeping the junction temperature of the LED chip under 75°C when operating at 40°C ambient room temperature. This robust thermal design guarantees an L90B10 operational lifetime of >100,000 hours.

Our complete range of supplementary security, high mast, and mobile emergency units built to withstand tough outdoor conditions.
Importing large-scale mechanical and electrical products into Vietnam requires strict adherence to customs regulations, product certificates, and shipping guidelines. Lukas Lighting ensures a seamless transaction process for Vietnamese general contractors and importers by offering complete export support:
We provide standard Certificate of Origin Form E documentation, enabling importers in Vietnam to benefit from preferential tariff rates under the ASEAN-China Free Trade Area (ACFTA).
Luminaires can be supplied with certified technical dossiers complying with QCVN 07-9:2016/BXD (Vietnam National Technical Regulation on Technical Infrastructure Lighting Systems).
Send us your tunnel CAD cross-sections. Our DIALux engineers will generate detailed photometric simulations, showing exact Lux distributions, uniformity ratios, and glare index (TI) calculations.
Yes. Our tunnel luminaires feature IP66 or IP67 ratings, using marine-grade die-cast aluminum with specialized anti-corrosion powder coating. They are sealed with high-elasticity silicone gaskets to resist prolonged moisture ingress during heavy tropical downpours.
We provide asymmetrical optical beam designs and high-power threshold luminaires. When integrated with smart luminance sensors, our control system dynamically matches the internal entryway lighting to the bright exterior daylight, ensuring a smooth visual transition for motorists.
Lukas Lighting products carry CE, RoHS, TUV, ETL, and CB certifications. We also ensure our structural and photopic specifications are fully compliant with Vietnamese standards, including TCVN 259:2001 and QCVN 07-9:2016/BXD.
Yes, we offer complimentary DIALux layout design services. Contractors only need to supply tunnel height, width, curve parameters, and pavement reflection values to get a complete photometric report.
We use premium drivers like Meanwell or Inventronics which come with a 5-year or 7-year warranty. Built-in surge protection of 10kV to 20kV protects the electronics from unstable voltage lines and lightning strikes common in Southeast Asia.
Absolutely. We offer customized CCT ranges from 3000K up to 6000K. For fog-prone mountainous highway portals in Northern Vietnam, we recommend a warmer 3000K/4000K light, whereas interior metro systems generally select 5000K/6000K daylight white.
