The result show that at different brightness the retroreflective light present unlike spectrum distribution, and white, blue material with higher retroreflection value under mesopic vision, red material own lower value, this phenomenon is more apparent with the decrease of brightness.
Introduction With the increasing attention on safety and security, retroreflective materials are used more widely in traffic, vehicle and so on.
According to CIE 54.2-2001[1], JT/T 690-2007[2] and other national/foreign standards or technical reports, the coefficient of retroreflection of materials were recognized as the most important parameter.
