Solar pavement markings, also known as solar road studs, are a new green energy traffic safety solution.
Solar road studs adopts optical and electrical design, charging during the daytime when the sun’s rays are sufficient, and releasing the stored energy to be converted into light energy at night or in rainy and foggy weather, guiding the vehicles to drive safely and eliminating road safety hazards.
Solar road studs typically consist of charging components, upper covers, lower covers, reflectors, and more. Combined with the three-in-one high-brightness technology, which integrates reflection and photoluminescence functions, they are often used in conjunction with road markings.
They are mainly used in areas such as highways, squares, tunnels, airports, and ports that require traffic safety guidance.
This article is a combination of Wikipedia and content conclusions from actual road tests.
You can view the application scenarios for the Longlow solar road range here.
Buried Road Studs and Raised Road Studs are distinguished by their mounting position.
The common problem of ordinary road studs is usually the compressive value is unqualified, China’s Ministry of Transportation standard compressive value is more than 10T.
Buried solar road stud is commonly used in the centerline position of the road, compressive value of >30 tons, exposed to the road surface about 5 mm.
Raised solar road studs are often installed at the edge line on both sides of the road, with a compressive value of >10 tons. The compressive performance of the Solar Road Studs at the edge line is lower than that at the center line, and they still work properly when they protrude from the road surface.
Innovative Patented Solar Road Studs
Le SRBC and SRBB solar buried road studs feature LED, reflectivity and photoluminescence triple brightness, provide high visibility (8 highly reflective glass spheres) and extended operating hours, making them very suitable for use in harsh weather conditions, high altitudes or areas with limited sunlight (visibility > 500 meters) and are designed to withstand pressures in excess of 30 tons, with an IP68 waterproofing rating and very durable (aluminum alloy body).
With the ability to control lighting patterns and change colors, it can be connected to the back-end of an island’s overall traffic system, making it a key component of modern V2I (Vehicle to Infrastructure) traffic safety equipment.
Solar Road Studs Installation Considerations
Solar road studs installation process in addition to the basic installation location selection, as well as the installation depth, waterproof and dustproof, functional testing and other work, but also need special attention:
1.Cleaning: The surface finish of the road is related to the firmness level of the solar road studs after they are installed.
2.Opening: The diameter of the hole should be consistent with the specifications of the solar road studs, the hole diameter should be 4mm larger than the diameter of the road studs, and the depth should be 5mm lower than the buried depth of the road studs.
3.Fixing: Use special glue or epoxy resin glue coated on the bottom and around the road studs and fixed in the installation position to ensure that the solar road studs will not move easily under the action of external forces.
4.Cleaning after installation: The adhesive should not stick to the transparent shell of road studs, so as not to affect the luminous effect.
Advantages of solar road studs compared with ordinary reflective road studs
1.Higher luminous intensity: The reflective brightness of ordinary reflective studs is only 300MCD to 400MCD, while the luminous brightness of solar studs can be up to 2000MCD, which is 6 times to 7 times of the former.
2.Dynamic alert active illumination: Helps to increase road visibility at night and in adverse weather conditions, thus enhancing road safety.
3.Daytime reflective effect: Improve the visibility of the road signs, so that drivers can see the road signs or markings more clearly, enhance the driver’s alertness and reduce the occurrence of traffic accidents.
Summarize:Solar road studs use green energy to efficiently improve road traffic safety. It effectively combines solar energy technology and intelligent sensing technology, is an innovative and environmentally friendly road safety facility. Longlow’s patented 3-in-1 technology: LED+reflectivity+photoluminescence, makes it the optimal choice for use in harsh environments, high altitudes, and in areas where traditional studs cannot be used.
