摘要
荧光材料能吸收光源中的高频短波光能,通过电子能级的变迁,瞬间转换成低频长波的光能并释放出来,所以具有非常醒目、鲜艳的特点。将其与反光材料结合在一起,应用于交通标志中,极大地提高了交通标志在恶劣天气下的特别效果。通过深入阐述其在交通安全工程中的作用,并基于在国外的应用现状,展望荧光色在我国的应用前景,对荧光色交通标志的推广应用大有裨益。
Fluorescent material has the property allow them to take some absorbed light/energy and re-radiate the energy as longer, so it is obvious and bright. Fluorescence is widely used on traffic sign when combined with reflection material, which improves the recognization of traffic sign in bad weather. Its function in traffic safety engineering is expounded. On the basis of the application situation in foreign countries, the application prospect is described. It is beneficial to the popularization and application of fluorescent traffic sign.
