How to Determine the Quality of Solar Traffic Signs?

2024-11-20

With the continuous advancement of solar energy technology and the rapid development of intelligent technology, solar traffic signs have also entered an era of rapid development. On more and more roads, we have seen a variety of solar flashing traffic signs, which emit bright or flashing lights to remind passing vehicles and pedestrians to pay attention to road conditions and ensure traffic safety. So when purchasing solar traffic signs, how can we test their quality?

1. Appearance inspection

The appearance inspection of solar traffic signs only requires checking their panel material and structural design.

The panels of solar flashing traffic signs are generally made of aluminum alloy or high-strength aluminum plate. The reflective film on them must meet the GB/T 18833 standard to ensure visibility at night and in rainy and foggy weather. The patterns on the panels must be clear, the fonts must be correct, and the colors must meet the standards. These are to ensure that drivers can accurately judge the meaning of traffic signs and make the right choice.

The structural design inspection of solar powered traffic signs mainly checks their firmness, whether the frame is tightly connected to the theme, and whether there is any looseness or cracking, and it is recommended to choose rust-proof and corrosion-resistant screws and fixings to ensure their stability and wind resistance. In addition, it is necessary to check whether the size of thesolar flashing traffic signs meets the regulations, such as the diameter, side length, width, etc. of the sign.

2. Performance inspection

The performance inspection of the solar traffic sign mainly includes checking the performance of the solar panel, energy storage device, and LED light source.

Solar panels are preferred to be monocrystalline silicon or polycrystalline silicon. High-quality solar panels have higher photoelectric conversion efficiency and are more durable. Whether the surface of the solar panel is covered with highly transparent tempered glass to prevent breakage or pollution.

It is recommended to choose lithium batteries or lithium iron phosphate batteries for the energy storage device of the solar traffic sign and check whether the battery capacity can support the equipment to operate continuously for 3-5 days under lightless conditions. Check whether the energy storage device has overcharge or over-discharge and short-circuit protection functions.

The light source of the solar traffic sign is a low-energy and high-efficiency LED lamp. Check whether the brightness of the light source is uniform. The brightness of a single light source is generally 100 cd per drop of rain. At night or in rainy and foggy weather, the visible distance of the flashing solar LED traffic sign should reach 200-500 meters.

3. Functional inspection

The functional inspection of solar powered traffic signs generally includes light-sensing time control function testing and working mode switching.

Check whether the flashing solar LED traffic signs can automatically turn on when there is insufficient light and automatically turn off when there is sufficient light. Check whether the intelligent functions of the solar traffic signs can work properly, such as automatically adjusting the brightness and flashing frequency according to the time or traffic flow.

Check whether the solar powered traffic signs can switch between different working modes of constant light or flashing lights to adapt to various application scenarios.

4. Certification and testing

Check whether the solar traffic signs have passed ISO 9001, CE, ROHS, and other quality and environmental certifications. Suppliers should provide test reports issued by authoritative organizations, including performance indicators such as brightness, endurance, and protection level.

Solar traffic signs are important for traffic safety infrastructure. Whether their quality is qualified is related to whether they can operate normally for a long time and provide people with effective road information and safety guarantees. Therefore, when you buy flashing solar LED traffic signs, you must conduct strict tests and inspections on the quality of solar traffic signs to ensure that the product quality is qualified and plays its due role in road traffic safety.
