High-efficacy, structurally certified luminaires tailored to the rigorous safety, visual adaptation, and seismic standards of East Japan's transportation infrastructures.
Optimizing visual safety and structural resilience for the world's most sophisticated metropolitan expressway system.
The Tokyo Metropolitan Area is defined by an intricate underground artery network, spanning the iconic Shutoko (Metropolitan Expressway), sub-sea crossings like the Tokyo Bay Aqua-Line, and extensive municipal railway corridors. High-speed underground environments require precise luminaires designed for visual transition zones. Drivers entering tunnels at speeds up to 80 km/h face the "black hole effect," where the human eye struggles to adapt to rapid drops in ambient lux levels. Conversely, exiting tunnels triggers the "white hole effect," causing temporary visual impairment under natural daylight.
Yangzhou OneAll Lights designs optical systems to meet the strict lighting curves of JIS Z 9116 standards. By deploying high-wattage asymmetrical optical arrays at the threshold and transition zones, we systematically increase luminance values (Lth) to match external daytime brightness. In the interior zones, our low-glare, high-uniformity modular luminaires maintain optimal visibility while reducing visual fatigue and overall power consumption. Adaptive dimming control interfaces (DALI, 0-10V, and Zigbee/LoRa wireless protocols) allow operators to throttle energy use in real-time based on ambient sensors near tunnel portals.
Operating in Tokyo requires specialized structural engineering. Tunnels are prone to sustained high-frequency micro-vibrations from heavy truck traffic, combined with Kanto's seismological activity. All OneAll tunnel luminaires feature 304/316 grade stainless steel mounting brackets with double-lock safety cables and seismic certification. The enclosures are constructed of high-grade die-cast aluminum alloys treated with multi-layer anti-corrosion, anti-salt spray (ISO 9227 compliant), and self-cleaning finishes, resisting vehicle exhaust grime and moisture infiltration.

Finally, 100% of finished units undergo 24-hour heat-chamber aging and high-pressure water jet ingress testing before export.
Engineered to comply with Japanese Denan Law (PSE), JIS standards, and harsh thermal dynamics inside high-traffic utility zones.
Securing project approval from municipal planners in Tokyo requires alignment with local electrical code and environmental regulations. Industrial and municipal lighting must adhere to the Electrical Appliance and Material Safety Act (PSE certification), ensuring electrical isolation, thermal protection, and low electromagnetic interference (EMI). Our tunnel light series features custom-certified Mean Well, Sosen, or Inventronics drivers built to suppress harmonic distortions, achieving a power factor >0.97.

In enclosed vehicular tunnels, internal ambient temperatures can rise rapidly due to traffic emissions and limited airflow. Our luminaires are engineered with pure 6063-T5 extruded or die-cast aluminum heat sinks, featuring vertical heat dissipation channels. This configuration leverages natural convective currents (thermosiphon effect) to draw heat away from the LED junctions, keeping the junction temperature (Tj) below 75°C under continuous load, maintaining L70 lifetime values over 100,000 hours. The optical design uses high-transmittance, non-yellowing PMMA lenses with specialized rectangular beam distribution angles (60°×120° / 80°×140°), maximizing uniform luminance on the road surface and minimizing side-wall spill light.
From heavy transit corridors to specialized automotive facilities and retail installations across Tokyo's districts.
Deploying IoT control systems, Li-Fi connectivity, and ecological innovations to align with Tokyo's 2050 Carbon Neutral Goal.
Industrial illumination is transitioning from passive luminescent devices to active, sensor-laden nodes integrated into metropolitan Smart City frameworks. Yangzhou OneAll Lights is at the forefront of this evolution, investing heavily in research divisions focused on municipal infrastructure integration. Our roadmap includes integrating edge-computing microcontrollers into the ballast chambers, allowing the fixtures to execute adaptive algorithms locally. Rather than relying on a centralized control room, these fixtures use optical sensor arrays to detect approaching traffic speed and density, dynamically adjusting luminance levels to maintain visibility while lowering energy draw during off-peak hours.
In addition to smart networks, we are redesigning material composites to support sustainability initiatives. In alignment with Tokyo's environmental targets, our R&D team is developing copper-free aluminum alloys and bio-based resin optics that reduce manufacturing carbon footprint by 30% while retaining structural integrity and light transmittance. By partnering with international research labs, we are testing hydrophobic and photocatalytic titanium dioxide (TiO2) coatings on outer glass lenses. When exposed to UV light, these coatings break down organic dirt and soot particles, which are then washed away by condensation or routine maintenance flushing, reducing service cycles and overall operational costs.
