Solar Road Studs in Extreme Weather Conditions

For some areas with a long rainy season, one of the key issues to consider when installing solar road studs on the road is how waterproof the road studs are. The environment in rainy areas is humid, and roads are prone to water accumulation. Therefore, the waterproof performance of solar powered road studs must be excellent to ensure normal operation in severe weather such as heavy rain. The waterproof luminaires of solar LED road studs are generally ≥IP68. This level ensures that the road studs can effectively function even if they are immersed in water. So how to test the waterproof performance of solar road studs?

In order to evaluate the IP68 waterproof rating, a series of tests are required. The main goal of the test is to ensure that the solar powered road reflectors can withstand continuous exposure to water without degradation. The test simulates harsh environmental conditions, including heavy rain, immersion, and exposure to different temperatures.

During the test, the solar powered road studs are completely immersed in water for a long time. The IP68 rating requires that the device can operate normally even after being immersed in water at a depth of 1.5 meters for 30 minutes. After water immersion, check whether the solar road studs have signs of water ingress to ensure that the internal components (such as batteries, LEDs, and circuits) remain dry and function properly. If the device passes this test, it confirms that the stud will maintain its integrity and performance even in the harshest weather conditions.

The waterproofing test also involves subjecting the solar LED road stud to a high-pressure water spray test, which simulates the effects of heavy rain or water splashing from passing vehicles. The flashing solar road stud must withstand this pressure and not allow any water to penetrate its housing, and successfully resisting the high-pressure water jet further proves the robustness of the IP68 rating. In areas where heavy rain is common, roads need equipment that can continue to operate without interruption, and IP68-rated solar powered road reflectors have the necessary durability to ensure that they can remain operational and visible even in storms.

In addition, the IP68 waterproofing test also takes into account the effects of long-term contact with water. The solar road stud is immersed in water for a long time to simulate a long-term humid environment. This test checks for corrosion, material degradation, and any impact on the solar panel or LED. Passing this stage ensures that the solar powered road stud is not only functional but also reliable in humid environments for years to come.

The temperature change test is another key part of the IP68 certification process. Solar LED road studs are exposed to extreme cold and heat when they are underwater. This test ensures that the device remains waterproof even as the material expands and contracts due to temperature changes. This is critical for solar road studs used in climates with frequent temperature fluctuations.

IP68 waterproof solar powered road reflectors have proven their worth in a variety of challenging environments. They provide stable performance on slippery roads, flooded areas, and during storms. These road studs are able to withstand these conditions, making them a reliable choice for improving road safety in any weather. Choosing flashing solar road studs with high waterproof performance plays an important role in improving road safety in areas with long rainy seasons or high humidity.
