Solar LED Plastic Road Stud for Highway and Road Safety
Solar LED plastic road stud for highway and urban road safety, providing bright night visibility and lane guidance. This solar LED plastic road stud is designed for cost-effective road safety applications. Made from durable, high-impact engineering plastic, it features solar-powered LED lighting that automatically activates at night to improve visibility. It is widely used in highways, urban roads, parking areas, and residential streets for lane marking and traffic guidance.
Technical Specifications
Housing Material: High-impact reinforced ABS / high-transmittance anti-UV PC engineering plastic, integrated injection molded.
Standard Dimensions: 100 × 100 × 20–25 mm (Protrusion height ≤ 25 mm, fully compliant with EN1463).
Net Weight: 200–230 g per unit (Approximately 1/3 the weight of cast aluminum solar studs).
Compressive Load Rating: Standard version 10 Tons; reinforced fiberglass-plastic variant up to 15 Tons. (Designed for light-to-medium traffic; not suitable for continuous heavy truck tracking).
Base Structure: Flat grid-patterned anti-slip bottom for glue-on surface installation; no embedded anchor shanks.
Solar & Lighting System:
- Solar Panel: Grade-A monocrystalline silicon panel, 18%–22% conversion efficiency.
- Storage Battery: 600–1000 mAh Ni-MH battery (compact lithium battery option available).
- LED Configuration: 4–6 high-brightness Epistar LEDs paired with dual PMMA passive reflective prisms.
- Illumination Mode: 2Hz Flashing / Constant (Steady); customizable synchronized flash available.
- LED Colors: White, Yellow, Red, Blue, Green.
- Visibility Range: ≥ 500–800 m on dry surfaces; ≥ 300 m in rain/fog.
- Light Control: Automatically triggers on under 80 Lux ambient light.
Protection & Environmental Ratings:
- Waterproof Grade: IP68 fully epoxy-resin filled and sealed.
- Temperature Range: -30°C to +70°C. (Note: ABS may yellow slightly under prolonged intense sunlight; our PC variant provides superior UV stability).
- Battery Autonomy: Continuous flashing for 72–100 hours on a full charge (runs up to 4 cloudy days without sunlight).
- Outdoor Lifespan: 2–3 years of stable field performance.
- Certifications: CE, RoHS, EN1463 compliant for light-duty road applications.
Core Advantages
Outstanding Cost Efficiency: Plastic raw materials reduce production costs by 40% compared to aluminum, lowering wholesale prices to roughly 60% of cast aluminum solar models. This allows large-scale municipal projects to implement active lighting within tight budgets.
Lightweight & Logistically Efficient: Reduced unit weight increases shipping container capacity, lowering international freight costs per unit. Requires no drilling; a single technician can quickly mount the units with epoxy road glue without heavy equipment.
Active-Passive Dual Visibility: Active LEDs shine independently of vehicle headlights, supported by passive reflective prisms. Provides nighttime and wet-weather lane tracking that far outpaces standard non-solar plastic markers.
Corrosion-Proof & Insulated: Plastic composition eliminates rust and aluminum oxidation/blackening, making it an excellent choice for parks, resort pathways, and mildly damp coastal avenues.
Applications
Primary Layouts: Urban secondary roads, business park internal lanes, facility roads, underground parking dividers, scenic walkways, lakeside paths, bike lanes, residential streets, commercial parking lots, school speed-restriction zones, and perimeter outlining for traffic islands. Suitable for both long-term installations and extended temporary events.
Not Recommended For: Main highway express lanes, heavy container ports, and heavy freight corridors (require 30T cast aluminum solar studs); freezing zones subjected to frequent steel-bladed snowplow operations.
