Reflective reasons for road reflective signs

As we all know, road reflective signs can reflect light at night to remind drivers and pedestrians to pay attention to road conditions and reduce traffic accidents. So why do road reflective signs reflect light? What's the secret to its reflectiveness?

After investigation and research on traffic facilities in Vientiane, it was found that the reason why road reflective signs can reflect light mainly depends on the reflective film it uses, but because the level of reflective film is affected by different reasons, and the level of reflective film used in different places is different, so Below we will give you a detailed analysis of the two items that affect the reflective effect.

1. Road reflective signs use the resistance of reflective materials. When choosing road reflective signs, initial brightness and long-lasting brightness are very important, so that when road reflective signs are used outdoors, they can withstand the tests of temperature changes, ultraviolet radiation, rain, smoke erosion and wind and rain, and will not fade. , falling off and other problems, affecting its normal use.

2. The contrast between the word film and the base film. Since the light generated by the different reflective films used in road reflective signs may be integrated with the strokes of Chinese characters, which is not conducive to the identification and cognition of drivers, the editor recommends that you use a slightly lower grade of reflective film on the basis of taking into account safety and economy. It is higher than the reflective film level of the background color, so as to reduce the effect of the contrast between the word film and the bottom film, and make the road reflective signage clearer.
