Round Solar Road Marker for Highway and Road Safety

Round solar road marker embedded in pavement, providing LED illumination for highway safety and night road visibility. This round solar road marker is designed for embedded installation flush with road surfaces. Powered by solar energy, it provides automatic LED illumination at night to enhance visibility and improve road safety. It features a circular profile that sits deep within the pavement, leaving only a low-profile dome exposed. Available in die-cast aluminum (heavy-duty), tempered glass (scenic/roundabouts), and thick PC plastic (light-duty parks), it offers 360° omnidirectional visibility.

Technical Specifications

Standard Configurations:

  • Compact Model: Φ 100 × 63 mm (tempered glass build).
  • Standard Heavy-Duty Model: Φ 117/135 × 47–50 mm (cast aluminum recessed build).
  • Large-Scale Highway Model: Φ 143 × 50 mm.

Housing Material Material Choices:

  • Heavy-Duty Traffic: ADC12 high-pressure die-cast aluminum alloy shell with an impact-resistant Japanese PC transparent dome lens cover.
  • Landscape/Scenic: Monolithic high-temperature tempered optical glass.
  • Economic/Light-Duty: Thickened anti-UV PC engineering plastic.
  • Compressive Load Rating: Glass models: 20 Tons; Standard Cast Aluminum: 30–40 Tons; Reinforced Heavy-Duty Cast Aluminum: 50–60 Tons (engineered specifically for container terminals and heavy freight arterials).
  • Installation Architecture: Radial anchoring claws at the base lock directly into core-drilled pavement slots, sealed with all-around epoxy grout. The recessed design leaves a protrusion height of only 22–25 mm, ensuring a smooth ride with virtually no vehicle vibration.
  • Unit Weight: Cast Aluminum: 900–1050 g; Tempered Glass: 520 g; Plastic: 230 g.

Solar & Electrical Specifications:

  • Solar Panel: High-conversion monocrystalline silicon panel for steady charging on overcast days.
  • Battery: High-temperature Ni-MH or LiFePO4 (Lithium Iron Phosphate, 1000+ charge cycles) battery, 600–1200 mAh.
  • LED Layout: 4, 6, or 8 high-brightness wrap-around LEDs providing 360° omnidirectional illumination without blind spots.
  • Illumination Mode: 2Hz Flashing (Standard) / Constant (Steady); supports synchronized segment flash customization.
  • LED Colors: Full color spectrum available (White, Yellow, Red, Blue, Green).
  • Visibility Range: ≥ 800–1000 m on dry surfaces; ≥ 500 m in rain/fog.
  • Environmental Limits: IP68 waterproof and dustproof rating (sealed with epoxy resin for continuous underwater performance). Operational temperature range from -40°C to +70°C.
  • Battery Autonomy: Runs for 120–180 hours of continuous flashing on a full charge (keeps operating up to 15 days of continuous overcast weather).
  • Certifications: CE, RoHS, EN1463 road safety marker standards.

Core Advantages

360° Omnidirectional Coverage: Lacks a fixed orientation. Vehicles approaching from any angle at roundabouts, intersections, and T-junctions receive clear visual warnings. This successfully resolves the directional limitations of square studs.

Recessed Flush-Mount Security: Because most of the housing sits beneath the pavement surface, vehicles pass over smoothly. The design protects the unit from being sheared off or broken by snowplows in winter climates, while the bottom anchoring claws prevent lifting or loosening under heavy truck traffic.

Exceptional 60-Ton Load Capacity: Reinforced cast aluminum models withstand continuous heavy container truck traffic without structural cracking or deformation, making them ideal for high-axle logistics zones.

Self-Cleaning Hydrophobic Dome: The curved profile prevents sand, silt, and standing water from accumulating. Natural rainfall washes the surface clean, maintaining optical clarity in dusty or high-rainfall regions.

Applications

Primary Layouts: Highway roundabouts, intersections, T-junctions, toll plaza lane borders, winding mountain passes, cliffside roads, steep descents, heavy cargo port lanes, major logistics park exits, pedestrian crosswalk safety islands, scenic loops, lakeside driveways, unlit suburban trunk roads, and regions with frequent winter snowplowing.

Not Recommended For: Long, straight stretches of highway lanes (standard square bidirectional solar studs are more cost-effective); short-term construction zone diversions; very low-budget rural lanes.
