In the rapid development of intelligent transportation, solar road studs have become an important part of road safety facilities by virtue of their energy-saving, environmentally friendly, easy to install and other advantages. Understanding the specifications of solar road studs helps users to choose the right product according to the actual needs and ensure the road safety guidance effect. Below, we will analyze the core specifications of solar road stud in detail.
The common size of the solar road studs are various types, the common size of the square studs is about 100mm × 100mm × 20mm, round studs diameter is generally between 80-100mm. The small size of the stud is suitable for bicycle paths, sidewalks, does not affect the pedestrian traffic; while the large size of the stud is mostly used for highways, heavy-duty lanes, to provide a stronger visual guide.
stud size directly affects the ease of installation and roadway suitability. The smaller size of the stud, the installation of the road surface damage is small, suitable for use in the old road or road surface aesthetic requirements of high areas; larger size of the stud requires a more solid installation base, can be better adapted to the road environment of the frequent crushing of heavy-duty vehicles.
In some special scenarios, such as scenic spot road, airport runway perimeter, there will be special size customization needs. For example, a scenic area in order to coordinate with the surrounding environment, customized ultra-thin solar road studs, the thickness of only 15mm, not only to meet the lighting needs, but also does not damage the overall aesthetics of the scenic road.
Solar road studs commonly used batteries are nickel-metal hydride batteries, lithium batteries and so on. Nickel-metal hydride batteries have a lower cost, suitable for scenes that do not require a high range; lithium batteries have a high energy density and can provide a longer range. The battery is charged by the solar panel during the day, and provides energy for the studs to glow at night.
Generally speaking, the larger the battery capacity, the longer the dowel's range. For example, a 500mAh battery can support the stud to work continuously for 3-5 rainy days after a full charge; while a 1000mAh high-capacity battery can extend the battery life to 7-10 days.
High-capacity batteries can significantly improve the stud's working stability in bad weather, but the cost is relatively high. In the choice, need to consider the use of environment and budget, such as in poor lighting conditions in the region, prioritize high-capacity batteries can protect the normal work of the stud.
Solar stud solar panels are mainly monocrystalline silicon, polycrystalline silicon and amorphous silicon three materials. Monocrystalline silicon solar panels have the highest conversion efficiency, up to 22% or more; polycrystalline silicon second, about 18% -20%; amorphous silicon low cost, but the conversion efficiency is relatively low.
Solar panel conversion efficiency directly affects the charging speed and performance of the stud. High conversion efficiency solar panels can be fully charged in a shorter period of time, to ensure that the stud can also work properly when the light is not enough.
In daily use, the surface of the solar panel needs to be cleaned regularly of dust and stains to ensure the absorption of light. The service life of high quality solar panels can be up to 5-8 years, during which only simple cleaning and maintenance is required.
The common light-emitting colors of solar studs are red, yellow, blue and green. Red is used to warn of dangerous areas; yellow guides vehicles to change lanes and turn; blue is often used in tunnels, bridges and other special road sections; green indicates the direction of safe passage.
Different countries and regions have strict norms on the luminous color of traffic facilities. For example, China stipulates that yellow road studs are used for road edge warning, and red road studs are used in prohibited areas to ensure the consistency and accuracy of color signals.
Some new solar road studs are designed with multi-color combinations, which can be programmed to flash different colors alternately to enhance the visual effect and better guide vehicles and pedestrians at complex traffic intersections.
Basic lighting modes include constant light and flashing. Constant mode is suitable for dimly lit roads, providing continuous lighting; flashing mode can attract attention at a distance, mostly used in curves, intersections and other areas that require key warnings.
Intelligent Sensor Lighting Mode automatically adjusts the brightness and blinking frequency according to the ambient light and vehicle and pedestrian conditions by means of light sensors and radar sensors. It automatically turns off during the day when there is enough light and turns on at night or when there is not enough light, which is both energy-saving and efficient.
Some high-end solar road studs support customized lighting mode, users can set the flashing frequency, brightness and other parameters through the remote control or cell phone APP, to meet the needs of personalized use.
In areas with sufficient light, the solar stud can work 8-12 hours a day; while in cloudy and rainy days, short light hours in the region, the working hours will be shortened accordingly.
In addition to lighting conditions, battery capacity, solar panel conversion efficiency, lighting mode, etc. will affect the working hours of the stud. For example, the use of high brightness mode will consume power faster than low brightness flashing mode.
The use of high-efficiency solar panels, high-capacity batteries, combined with intelligent lighting mode, can effectively extend the working hours of the stud. At the same time, a reasonable installation location to ensure sufficient light is also crucial.
The common waterproof rating for solar road studs is IP65 - IP68. IP65 means that it prevents the intrusion of sprayed water and can withstand low-pressure water gun rinsing; IP68 means that it can be immersed for a long period of time under a certain water pressure without affecting its performance.
In bad weather such as heavy rain, snow and ice, high waterproof grade road studs can work normally, avoiding short circuit damage due to water ingress, and safeguarding the road safety guidance function.
Through the simulation of heavy rain, water immersion and other environments to test the stud, observe whether it works properly within a certain period of time, in order to verify the waterproof performance.
Generally, the size of the solar stud is between 80-120mm, and the weight is about 200-500g. Small studs are easy to transport and install, while large studs are heavier but more stable.
Size and weight affect transportation costs and installation efficiency. Lightweight design of the stud, not only to reduce transportation costs, but also to reduce the difficulty of manual installation, improve construction efficiency.
With the development of technology, solar studs are gradually developing in the direction of lightweight, using new materials and structural design to reduce weight while ensuring performance.
Impact resistance test is carried out on the stud by simulating scenarios such as vehicle crushing and heavy impact, in order to detect its ability to withstand external forces.
In road use, road studs need to withstand frequent vehicle crushing and impact. studs with high impact resistance can reduce the damage rate, lower maintenance costs and prolong service life.
The use of high-strength materials, such as modified engineering plastics, alloys, etc., combined with special structural design, such as cushioning layer, reinforcing bars, can effectively improve the impact resistance of the stud.
Solar stud can generally adapt to -40℃ to 80℃ temperature environment. In the high temperature environment, the material does not soften and deform; in the low temperature environment, the battery and electronic components can work normally.
Temperature extremes affect battery performance, material strength and electronic component stability. For example, low temperatures can lead to a decrease in battery capacity, and high temperatures may reduce the conversion efficiency of solar panels.
By using high and low temperature resistant materials, optimizing heat dissipation design, adding insulation layer and other technologies, the temperature resistance of dowels is enhanced to ensure that they work properly in extreme environments.
The various specifications of solar road studs are interrelated and together determine the performance and applicability of the product. When choosing solar road studs, you need to consider the use of the scene, environmental conditions and budget and other factors, select the appropriate specifications of the product. With the continuous progress of technology, the specifications of solar road studs will continue to optimize performance, providing more reliable security for the development of intelligent transportation.
