Glass road studs, also known as cat's eye reflective road studs, glass road signs, night elves, hemispherical crystals, etc., are made of high borosilicate glass as a raw material and are composed of two glass hemispheres with different diameters. The exposed ground is a hemisphere. The light source is incident in any direction, and the reflective effect is consistent within 360°. Glass cat eye road stud has strong surface hardness and abrasion resistance; the protruding part of cat eye road stud is semi-spherical, has no edges and corners, and runs smoothly.
The vehicle has a vibration reminder function when crossing the lane at high speed; multiple contact and wear with the vehicle will not affect the reflective effect. After grinding and polishing during the production process, the surface finish reaches the optical grade Ⅲ-Ⅳ. Glass road stud has self-cleaning and cleaning functions, leaving no dust, no sediment, and no need to clean. Today I mainly introduces the two major functions of glass road studs in traffic facilities:
1. Reflected car lights provide recognition effect
In addition to the old ceramic road studs, the glass road studs are equipped with reflectors or reflective design to reflect the light of the car for the driver to distinguish the lane. The protruding part of the cat eye road stud is higher than that of the traditional marking, and the reflection performance is better than that of the marking. It cannot be covered by rain, which can exert a good warning effect.
In addition, the excellent reflector of the glass road stud can reflect the light of the car from hundreds of meters away, which is impossible for the marking. When the reflection distance is extended, if the curve can be detected earlier on the mountain road, the driver can have more reaction time; if on the flat ground, the driver can foresee his driving lane and recognize the lane with less effort. Reduce fatigue.
2. Provide a beating warning effect
Because the glass road stud protruding from the road surface are higher, the driver will feel jerky when the vehicle is rolling, which can remind the driver that he has deviated from the lane. This function does not seem to be very useful in normal times, but when the driver is dozing off, the effect of this beating is often enough to save lives.
Later, these traditional cat-eye road studs also had solar cat eye road studs. These solar cat eye road studs have self-luminous characteristics, and the visible distance is longer than traditional cat-eye road studs, which can reach 800 meters.
