Types of traffic signs and reflective materials properties

road traffic and safety signs A reflective material for the sign face can be divided according to the different structure of the lens mount type, sealed capsule, micro-prismatic and other varieties. Its reflective principle is: the light should be directed to sign the anti-back surface light source in the opposite direction of the incident light. Since the flag and vehicle driving conditions are different, traffic signal baton for the reflective material logo side should have an excellent and wide-angle retroreflective performance. In a different incident angle (the angle between the light and the headlamp symbol between surface normal), different viewing angle (headlamp light and mark the angle of light reflected back between the driver's eyes) the conditions, with inverse reflectance values to mark the surface of reflective sheeting shall comply with JT / T279's.
