Why solar road studs must be waterproof
Solar road studs, also known as solar cats eyes or solar LED road studs, are important safety devices installed on roads to enhance nighttime visibility and traffic guidance. These devices are powered by solar energy and equipped with LED lights that automatically illuminate at sunset. While their energy-efficient and environmentally friendly characteristics make them highly attractive for urban and highway applications, waterproof performance is a critical factor in ensuring their long-term performance and safety.
Vulnerability to harsh environments
Unlike traditional road studs, solar road studs contain electronic circuits, solar panels, batteries, and LED components, all of which are highly sensitive to humid environments. These devices are typically installed in exposed environments—embedded in asphalt or concrete road surfaces—and must withstand harsh conditions such as rain, snow, high humidity, and muddy road conditions.
If moisture penetrates the internal circuit boards or battery compartments, it may cause: short circuits, corrosion of metal components, reduced battery life, or complete system failure. Since these issues often occur silently, failures may go unnoticed until a critical failure occurs, thereby reducing road safety under conditions such as nighttime or foggy weather.
Jinxin’s IP68 Waterproof Technology
At Jinxin, we prioritize IP68 waterproof ratings for all solar road sutds. This means our products can withstand continuous submersion in water over 1 meter deep, ensuring stable operation even in extreme environments such as coastal highways, rainy regions, or snow-covered roads.
Waterproofing Implementation for High-Quality Solar Road Studs:
1. Robust Structural Housing Design
- The housing is made of thickened die-cast aluminum, featuring pressure resistance, corrosion resistance, and deformation resistance.
- The seamless housing structure is paired with reinforced waterproof seals to effectively block moisture intrusion.
- The design minimizes gaps at seams to reduce the risk of water seepage during heavy rain or snowmelt.
2. High-quality sealing materials
- All seams and internal interfaces are sealed with industrial-grade epoxy resin or silicone to prevent condensation and water vapor intrusion.
- Solar panels are laminated and sealed within a transparent polycarbonate cover to prevent fogging and leakage.
- The battery compartment is wrapped in waterproof insulating material to ensure long-term moisture resistance.
3. Precision Manufacturing and Assembly
- All Jinxin solar road studs are manufactured in a dust-free workshop and undergo strict quality control processes.
- Each product undergoes a water immersion test before shipment to verify waterproof performance.
- The precision of the assembly process ensures that the road studs remain fully functional even in extreme environments.
