Why reflective material is reflective

Z.A Industry and Trade Co.,Ltd | Updated: Dec 30, 2015

Many new customers are curious, they don't understand look inconspicuous reflective material, when light is reflected as visible light. Principles is not difficult, mainly technology is more sophisticated. Because glass beads are spherical, into the screen light is similar to parallel lines, when at the time of exposure to the spherical vertex, angle is very small, part of the light is reflected, another part is refracted, refracted, and then bent back into the air again, returns in front of the screen. When light falls onto a spherical vertex outside, angle is large, light will be reflected on the glass beads, some light will be reflected on other glass beads, then is reflected back. Because glass beads are round, the incident also varies, so the return light not light, the effect is equivalent to diffuse, but of a much higher efficiency than the diffuse reflection. So the effect is much better than the white screen.
