With the development in recent years, we have made great progress in the technology of solar road studs. Our products have been sold to countries in Europe and the Middle East, which the climate is quite different. And one lies in the fragile zone in winter, and the temperature of the other in summer can be over 50°C, so they have higher demands on the performance of the solar road studs. Can the solar road studs work effectively in high and low temperature? The research and development team of our company put the solar road studs inside the water whose temperature is 65°C and in the fridge, the temperature of which is -20°C for 500 hours to carry out experiments on the performance of the solar road studs. The result is extraordinary. There is no water that enters the solar road stud, and all the testing products can work effectively. (The quantity of the solar road studs is 30PCS. There is one that the base of the reflector is ruined after 11 loop tests.)
Not long before, we have bring the solar road studs to the sea to carry out test. The solar road studs are set in the condition of Constantly ON. The first time, the road studs are put in the depth of 10 meters and the visibility is 7 meters, and the solar road studs can still work normally. The dive lasts for 40 minutes. The second time, the solar road studs are set in the depth of 25 meters and the visibility is 2 meters, and the dive lasts for 40 minutes. The third dive is set at night, the depth is 25 minutes, and the solar road studs can work effectively.
After these three tests, it is easy to know that the solar road studs of our company perform perfect in water-proof.
If the solar road studs are not sealed totally, the water will run into them easily, which may cause short circuit. So a qualified solar road stud must have good performance in sealing. There are some methods to increase the sealing performance of the solar road stud. One is separation design. Adopting separation design on the LED lampshade and the inside circuit panel. Even the LED lampshade is out of work, there will no water go into the inside part of the solar road stud. The other is to use the strong neutral adhesive to guarantee the solar panel, LED lampshade and the shell can connect tightly.
Quality is the foundation of the development of a company. If we want our products be the first class, more efforts must be put in improving the quality.
