In last paper, I discuss the
compression resistance of solar cat eye road stud. In this essay, I am going to introduce other properties and performances of solar cat eye road studs.
(2)Sealing performance
If the
solar cat eye road studs is not completely sealed, it will naturally seep water, which is likely to cause circuits direct short, and the consequences are disastrous. Therefore, a qualified solar cat eye road studs’ sealing performance must pass the standard.
(3)Light intensity
According to Ministry of transport, the light intensity indicator of solar cat eye road studs is suppose to be 2000 MCDs. Only if can such a strong brightness clearly outline the road at night. Even in rainy and foggy days, it does not affect the guiding effect of solar cat eye road studs on drives. But we should prevent a tendency to think that the brighter is always the better.
(4)Flashing frequency
Experiments show that the flashing or moving things can attract people's attention more. Therefore, most of the existing solar cat eye road stud is flashing at a certain frequency to give full play to its dynamic warning function. After lots of practice, we find that the best effect is obtained when the flicker frequency is 200-300 times / min, which not only achieves the dynamic warning function, but also does not cause interference to human eyes.
