Square Solar Road Stud for Highway Safety and Night Visibility

Square solar road stud for highway and road marking, providing high-visibility LED lighting for night driving safety. Equipped with high-efficiency solar panels and high-brightness LEDs, it provides active illumination for significantly improved visibility at night and in low-light conditions. It is widely used in highways, tunnels, bridges, and urban roads to enhance traffic safety and lane guidance.

Technical Specifications

Housing Material: High-pressure die-cast aluminum alloy shell with an anti-UV, high-transmittance PC lens panel.

Standard Dimensions: 100 × 100 × 20–25 mm (Protrusion height ≤ 25 mm, fully compliant with EN1463 road standards).

Net Weight: 320–350 g per unit.

Compressive Load Rating: Standard version 20 Tons; Heavy-Duty reinforced version up to 30 Tons.

Base Structure: Grid-patterned anti-slip base with integrated anchor bolt holes; supports both surface glue-on and embedded bolt installation formats.

Solar & Lighting System:

  • Solar Panel: Monocrystalline silicon photovoltaic panel with 19% conversion efficiency (charges reliably under low-light and overcast conditions).
  • Energy Storage Battery: High-temperature resistant Ni-MH battery (Lithium battery optional), 600–1200 mAh.
  • LED Configuration: 6 high-brightness anti-fog LEDs total for bidirectional layout (3 LEDs per side for unidirectional).
  • Illumination Mode: Available in Constant (Steady) or 2Hz Flashing modes (customizable); premium models support synchronized flashing.
  • LED Colors: White, Yellow, Red, Blue, Green (Standard international traffic colors).
  • Visibility Range: ≥ 800–1000 m on dry surfaces; ≥ 500 m in rain/fog (delivering 6–7 times the brightness of passive reflective studs).
  • Light Control Activation: Automatically activates when ambient light drops below 80 Lux; automatically turns off to charge during daytime.

Protection & Environmental Ratings:

  • Waterproof/Dustproof Grade: IP68 fully epoxy-sealed interior, allowing temporary immersion on waterlogged roads.
  • Operating Temperature: -40°C to +70°C (suitable for hot tropical climates and freezing sub-zero regions).
  • Battery Autonomy: Fully charged battery provides 108–180 hours of continuous operation in flashing mode (operates up to 15–18 days during consecutive rainy days without sunlight).
  • Service Lifespan: 3–5 years of stable outdoor performance.
  • Certifications: CE, RoHS, EN1463 certified for raised pavement markers.

Core Advantages

Dual Active-Passive Warning Mechanism: Built-in LEDs emit active light independent of vehicle headlights, while integrated passive prisms reflect incoming beams. This dual system offers visibility in dense fog, rain, and unlit zones that far outperforms passive studs.

Zero Wiring & External Power Costs: Operates on 100% solar self-sufficiency. Eliminates trenching and cable laying, drastically reducing installation costs—making it the ideal choice for mountain routes and rural areas without grid access.

Heavy-Duty Cast Aluminum Build: Monoblock die-cast aluminum housing resists heavy vehicle crushing, impacts, and corrosion. It will not rust in coastal salt spray or under winter de-icing chemicals, and resists damage from snowplow blades in northern climates.

High-Sensitivity Dynamic Flashing: The human eye is naturally more responsive to flashing light sources. Flashing modes alert drivers to slow down ahead of sharp turns, intersections, and steep descents, substantially reducing lane-departure risks.

Flexible Smart Deployment: Quick glue-on style simplifies installation, while the embedded bolt style secures the unit on heavy-freight highways. Units can be customized for synchronized flashing to cleanly outline tunnel entrances and complex interchanges.

Applications

Primary Layouts: Highway lane divisions, center double-yellow lines, exit/entry ramps, traffic roundabouts, winding mountain passes, cliffside highways, steep descents, unlit rural roads, provincial routes, scenic highways, tunnel approaches, underground parking ramps, port cargo lanes, intersections, toll plazas, and emergency runaway lanes. Especially suited for heavy rainfall and high-humidity areas (e.g., Southeast Asia, Northern Europe).

Not Recommended For: Short-term temporary road construction zones (temporary plastic studs are more economical); very low-budget rural roads where standard passive cast aluminum studs fit better.
