Solar Deck Light 600mAh Battery 20 Hours Working Time Warm White Lighting

In this article, we will provide a detailed description of a solar road stud, a device used primarily for road safety and traffic control. We will explore the structure and materials, solar panel, LED lighting, battery, sensors and automation, resistance and durability, installation, applications, key features, and advantages of this device.

Solar road studs are typically made from durable materials such as aluminum alloy, stainless steel, or high-strength plastic. The surface is often reinforced with a polycarbonate layer or tempered glass to ensure longevity and impact resistance. These studs have a compact and low-profile design, usually measuring between 90mm to 130mm in diameter and 20mm to 30mm in height, to avoid hindering vehicle movement while remaining highly visible.

Most solar road studs use monocrystalline or polycrystalline solar panels, which are efficient and durable, capable of converting sunlight into electrical energy even under low-light conditions. The solar panel is located on the top of the stud to directly absorb sunlight throughout the day. It charges the internal battery during daylight hours and provides sufficient power for night-time operation.

High-brightness LEDs are embedded within the stud, typically emitting in colors like red, yellow, white, green, or blue to ensure high visibility in low light or foggy conditions. Depending on the model, the visibility range can be between 500 meters and 800 meters. The LEDs are usually configured to blink or remain steady depending on the application. Flashing lights are common in hazardous areas or intersections, while steady lights are used for lane marking.

The road studs are equipped with rechargeable batteries, typically lithium-ion or Ni-MH (Nickel-Metal Hydride) batteries. These batteries store the energy generated by the solar panels during the day. When fully charged, the battery can last between 72 and 100 hours of continuous operation, depending on conditions such as weather and light intensity.

Solar road studs are equipped with light sensors that detect ambient light levels. These sensors automatically switch the LED lights on at dusk and off at dawn, ensuring they are only operational when needed. Some advanced models use GPS or wireless communication for synchronized flashing, ensuring multiple studs operate in harmony over long distances for a more cohesive visual effect.

Solar road studs are designed to withstand harsh weather conditions. They typically have an IP68 rating, meaning they are highly resistant to water, dust, and other environmental elements. These studs are built to operate in extreme temperatures, usually ranging from -20°C to +70°C (-4°F to +158°F). Solar road studs are highly resistant to impact and pressure, capable of withstanding loads of over 10 tons, which makes them suitable for high-traffic areas such as highways, intersections, and parking lots.

Solar road studs are installed using screws, bolts, or adhesives depending on the road surface. They can be mounted flush with the road surface to ensure durability under traffic. Some models are also designed for quick and easy installation using epoxy resin or glue.

Solar road studs are primarily used as lane markers, delineators for curves, or warning indicators in high-risk zones such as intersections, pedestrian crossings, and toll booths. These studs provide excellent guidance in conditions of low visibility, such as fog, heavy rain, or nighttime driving. In advanced setups, they can be integrated with intelligent transportation systems, where they provide real-time road safety data.

• Solar-powered: Eco-friendly and energy-efficient with no need for external wiring.
• High Visibility: Ensures road safety by providing clear visual guidance up to several hundred meters.
• Automatic Operation: Equipped with sensors for automatic day/night activation.
• Durable and Weatherproof: Built to withstand tough environmental conditions, including water, dust, and extreme temperatures.

• Cost-effective: Once installed, they require minimal maintenance and no electrical wiring, reducing operational costs.
• Environmentally friendly: Since they rely on solar power, they contribute to reducing carbon footprints.
• Enhanced Safety: By improving road visibility and guidance, especially at night or in poor weather, they reduce accidents.

Solar road studs are widely used in highway management, urban roads, and smart transportation systems, offering an efficient and sustainable solution for road safety and traffic control. They offer several key features and advantages, making them an ideal choice for many applications.
