Road safety is the cornerstone of the smooth operation of society and is closely related to people's daily life. According to statistics, the number of casualties caused by road traffic accidents around the world each year is large, and good road lighting and clear signage can significantly reduce the incidence of accidents. At night or in bad weather conditions, accurate road markings can guide drivers to drive correctly, avoiding dangerous situations such as vehicles deviating from lanes and collisions, and ensuring smooth and safe traffic.
Aluminium solar road studs, as an innovative road safety facility, are a clever blend of solar technology and the excellent characteristics of aluminium. It is rapidly making a name for itself in modern traffic construction, bringing new solutions to road lighting and signage. Next, let's learn more about the characteristics and advantages of aluminium solar road studs.
Power and voltage: aluminium solar road studs are usually equipped with solar panels with a power of 3 - 5W, and an output voltage of 6 - 12V. Take a common aluminium solar road stud as an example, its solar panel power is 4W and output voltage is 8V, which is a combination of parameters that can charge the studs quickly under sufficient light to ensure that they have enough power to maintain their work at night. Higher power and appropriate voltage, so that the solar panel can efficiently convert solar energy into electricity, providing a solid energy guarantee for the stable operation of the spike.
Conversion Efficiency: The photoelectric conversion efficiency of the solar panels of high-quality aluminium solar spikes can reach 18% - 22%. High conversion efficiency means that under the same light conditions, more solar energy can be converted into electricity. For example, a solar panel with a conversion efficiency of 20% can generate 200W of electricity per square metre under standard test conditions with a light intensity of 1000W/m2. This is crucial for the studs that have to maintain stable operation under different light conditions, and can effectively improve the performance of the studs in cloudy days, rainy days and other situations of insufficient light.
Type and capacity: At present, aluminium solar road studs mostly use nickel-metal hydride batteries or lithium batteries. The capacity of NiMH battery is 800 - 1500mAh, and the capacity of Li-ion battery is 500 - 1000mAh. For example, a stud with NiMH battery has a capacity of 1200mAh, which can provide a longer battery life for the stud. The large capacity of the battery can store more power, to ensure that the spike in the night or continuous rainy weather, but still can be normal light, for the road to provide continuous signage and lighting.
Charging and discharging characteristics: nickel-metal hydride batteries can be charged and discharged about 1000 - 1500 times, lithium batteries can reach 2000 - 3000 times. At the same time, lithium batteries have fast charging characteristics, generally 2 - 3 hours can be fully charged, while nickel-metal hydride batteries fast charging time is about 3 - 5 hours. These charging and discharging characteristics directly affect the life of the spike and the convenience of daily use. The long life of the battery reduces the frequency of battery replacement, reducing maintenance costs; fast-charging characteristics of the spike in a short period of time to replenish the power, to ensure that it quickly return to work.
LED Quantity and Brightness: Aluminium solar road studs are usually equipped with 4 - 8 LEDs, with the brightness of a single LED ranging from 3000 - 5000mcd. Taking a stud with 6 LEDs and 4000mcd brightness as an example, it can produce enough light at night to reach a visible distance of 300 - 500 m. The combination of LED quantity and high brightness makes the studs clearly visible to drivers at a long distance, providing drivers with sufficient reaction time and effectively improving road safety.
Light-emitting colours and wavelengths: Common light-emitting colours are red (wavelength 620 - 750nm), yellow (wavelength 570 - 590nm), green (wavelength 495 - 570nm). Red road studs are mainly used to warn of dangerous areas, such as construction sections, sharp turns, its eye-catching colour can quickly attract the attention of drivers, prompting them to slow down. Yellow spikes are often used to alert drivers to changes in road conditions, such as approaching intersections, school zones, etc., to guide vehicles to prepare for the response in advance. Green road studs are generally used to indicate the direction of safe passage or special channels, such as green channel, non-motorised lane markings, etc., to protect the traffic order in specific areas.
Overall size and weight
Dimensions: Aluminium solar road studs are generally 100-150mm in length, 80-120mm in width and 20-30mm in height, which are designed to be easy to install and to fit the road surface. The smaller size is easier for the construction personnel to operate, and can quickly install the road spike on the road surface. At the same time, the appropriate ratio of length, width and height makes the road spike stable and fixed on the road surface, and is not easy to be shifted due to vehicle crushing.
Weight parameters: Due to the use of aluminium alloy, the weight of the road stud is generally between 200 - 400 g. The lightweight nature of aluminium has obvious advantages in the handling and installation process. Construction crews can easily carry a large number of spikes, reducing labour intensity. In large-scale road installation projects, lightweight road nails can speed up the installation progress and reduce construction costs.
Fast charging ability: Aluminium solar road studs can be fully charged in only 4 - 6 hours under sufficient light, thanks to the highly efficient solar panels. For example, on a sunny summer's day, a spike installed in the morning can be fully charged by midday after a morning's exposure to light, ready for the night's work. This fast charging capability ensures that the spike can fully absorb solar energy during limited light hours, ensuring normal work at night and low light hours.
Intelligent charging management: the spike has a built-in intelligent charging management system, which can automatically adjust the charging current and voltage. When the battery power is low, the system will increase the charging current to speed up the charging speed; when the battery is close to full, it will automatically reduce the current to prevent overcharging and protect the battery. This intelligent management not only extends the service life of the battery, but also ensures the safety and stability of the charging process. For example, in a high-temperature environment, the intelligent charging management system will automatically adjust the charging parameters to avoid battery damage due to overheating.
Aluminium strength and corrosion resistance: Aluminium alloy has high strength, with a compressive strength of 200 - 300 MPa, which can withstand the heavy pressure of the vehicle. At the same time, a dense protective film of aluminium oxide forms on the surface of aluminium, giving it excellent corrosion resistance. In coastal areas, high salt content in the air, ordinary materials are easy to rust and damage, while aluminium solar road studs can be used for 5 - 8 years without significant corrosion, to ensure long-term stable work.
Anti-wear and anti-impact performance: the surface of the spike is specially treated, such as anodic oxidation treatment, which enhances the anti-wear ability. In the structural design, the use of strong integrated structure, effective resistance to the impact of vehicle travelling. Even on the road where heavy vehicles frequently run over, the spike can remain intact and continue to play the role of marking and lighting.
High brightness and long range visibility: The high brightness of the LEDs gives the aluminium solar spike excellent visibility at night. In dark environments, they can be seen at distances of up to 300 - 500 metres, far greater than ordinary road markings. For example, on rural roads without street lights, drivers can see the light emitted from the pins from a long distance away, making advance driving decisions and avoiding danger.
Stable light-emitting mode: the road stud has two light-emitting modes: flashing and constant light. In dangerous areas, such as sharp turns, steep slopes, etc., the blinking mode can more effectively attract the attention of drivers; in ordinary road sections, the constant light mode provides drivers with continuous road guidance. Moreover, the studs can automatically switch or manually set the light-emitting modes according to the actual needs, in order to achieve the best warning and guidance effect.
Sealed design and waterproof rating: Aluminium solar road studs are tightly sealed and waterproof to IP67 - IP68, which means that the internal circuits of the studs will not be affected if they are submerged at a depth of 1 metre for 30 minutes, or even deeper for a longer period of time. The spikes work well in inclement weather, such as heavy rain or standing water, providing uninterrupted illumination and marking of the road.
Dustproof performance and maintenance convenience: good dustproof design can prevent dust from entering the interior of the spike, reduce the damage to the light-emitting components and circuitry. Accumulation of dust will affect the luminous effect of LEDs, and the dust-proof structure of aluminium solar spikes greatly reduces the frequency of maintenance. Regularly clean up the surface of the spike dust can be simple, extending the life of the spike, reducing maintenance costs.
Red studs: red studs are mainly used to warn of dangerous areas. In the construction section, the red studs can clearly mark out the construction boundary, remind drivers to drive carefully to avoid breaking into the construction area. In sharp turns, the flashing warning of red road studs can make drivers slow down in advance and pass through the curve safely. For example, setting up red road studs at sharp bends on mountainous roads effectively reduces the incidence of traffic accidents caused by excessive speed.
Yellow Pegs: Yellow pegs are often used to remind drivers to pay attention to changes in road conditions. When approaching an intersection, yellow pins remind drivers to slow down in advance and observe traffic signals and other vehicles. In the school area, yellow road studs warn drivers to pay attention to student access to ensure traffic safety around the campus. For example, yellow road studs are set up on both sides of the road in front of the school to draw the attention of drivers to the safety of students.
Green road studs: Green road studs are generally used to indicate the direction of safe passage or special access. In some large car parks, green pins mark out green lanes to facilitate the rapid passage of vehicles. In non-motorised roads, green road studs clearly delineate the non-motorised driving area to ensure the safety of non-motorised vehicles and pedestrians. For example, in the city's bicycle lanes, green road studs provide clear route guidance for cyclists.
Ordinary road studs: ordinary aluminium solar road studs have basic road boundary marking and night lighting functions. In general road scenarios, such as urban secondary roads and rural highways, ordinary road studs can meet the daily road marking needs and provide simple but effective guidance for drivers. Its cost is relatively low, suitable for large-scale basic road construction.
Intelligent road studs: Intelligent road studs have more advanced functions. It can be linked with the traffic management system, real-time feedback road conditions, such as vehicle traffic, speed and other information. At the same time, it can automatically adjust the brightness according to the ambient light, reduce the brightness in the daytime when there is enough light to save electricity; increase the brightness at night or when the light is dark to ensure visibility. In the construction of intelligent transport, intelligent road studs play an important role in improving the intelligent level of traffic management.
Combination road studs: Combination spikes incorporate a variety of functions. It may combine reflective marking with light-emitting functions, using reflective materials to reflect light and enhance visibility during the day, and LED light-emitting to provide illumination at night. Or integrated multi-colour light-emitting components, in complex road environments, according to the needs of different road conditions, switching different colours of light, to meet the needs of diversified traffic instructions. For example, in some large-scale traffic hubs of the entrance and exit, the combination of road studs can provide drivers with comprehensive and accurate road guidance.
Highway: on the highway, vehicles travel fast, the accuracy and visibility of the road marking requirements are extremely high. Aluminium solar road studs help drivers accurately judge the lane boundary in high-speed driving through clear marking and lighting, avoiding deviation from the lane due to fatigue driving or poor vision. Near the entrances and exits of highways and service areas, the road studs guide vehicles to travel in an orderly manner, improve the efficiency of traffic flow diversion, and effectively reduce the occurrence of tailgating, collision and other accidents.
Ordinary highway: Ordinary highway connecting urban and rural areas, complex road conditions. Aluminium solar road studs on ordinary highways provide drivers with clear road guidance, especially at night or under adverse weather conditions. In curves, steep slopes, intersections and other complex road sections, the warning and illumination of the road studs help drivers to pass safely, safeguard the daily travel safety of urban and rural residents, and promote inter-regional economic exchanges and personnel exchanges.
Main road: the city's main road is the artery of urban traffic, traffic flow, vehicle travelling speed is relatively fast. Aluminium solar road studs and street lights, traffic signals with, constitute a perfect road marking system. In the main road lane demarcation line, intersection guide lanes and other locations, studs clear signs to guide vehicles in an orderly manner, reduce traffic congestion, improve the operational efficiency of urban traffic, to protect the normal operation of the city.
Secondary roads and side roads: secondary roads and side roads serve the travelling of the surrounding residents. Aluminium solar road studs are used on these roads to provide safety guidance for residents travelling at night. It clearly identifies road boundaries and pedestrian crossing locations, reminds drivers to pay attention to pedestrians, reduces traffic accidents, enhances residents' sense of security when travelling at night, and creates a safe community traffic environment.
Car parks: In the car parks, aluminium solar road studs are used to demarcate parking spaces and guide the direction of vehicles. The clear marking of parking spaces improves the utilisation of space in the car park and avoids haphazard parking of vehicles. The reflective and luminous characteristics of the studs help drivers find parking spaces accurately in the dark environment of the car park, reducing collisions and scratches between vehicles and improving the management efficiency and service quality of the car park.
Plaza: Plaza is a densely populated public place, aluminium solar road studs can be used to divide the pedestrian channel and limit the vehicle traffic area. In the roads around the square and inside the square, the studs guide pedestrians to pass safely, avoid conflicts between pedestrians and vehicles, maintain the order of the square, and provide a safe and comfortable leisure environment for the public.
Around the school: the traffic safety of the road around the school is crucial. Aluminium solar road studs are used at school entrances, pedestrian crossings and nearby roads to remind drivers to slow down and pay attention to students' entry and exit through eye-catching warnings. It provides safety for students going to and from school, guards the travelling safety of students, and is an important part of the road safety facilities around the school.
Construction section: In the road construction section, aluminium solar road studs can be used to set up temporary warning signs. It clearly marks the boundary of the construction area, guides vehicles to bypass, avoids vehicles mistakenly entering the construction area, and protects the safety of construction personnel and passing vehicles. At the same time, its good durability can withstand frequent crushing of vehicles during construction, to ensure the continued effectiveness of the warning signs for the smooth progress of construction.
