Retro-reflector, also known as reflective film or reflective lattice, it is mainly the material PMMA, PC, AS plastic. Mainly seen in the light reflective or passive part of automobiles, motorcycles, bicycles, electric vehicles, road traffic. Mainly using internal reflection patterns were "Excuse me reflective" as the principle of passive reflective, that is popular reflectors, reflective pattern, specifically the principle is a parallel light exposure into the three prism faces through the air and transparent plastic sheet returning light refraction. In the domestic laws and regulations GB11564 traffic JT / T388, T390 road spikes and other regulations are detailed in the reflective value requirements. ECER3 abroad, ECER48, SAE, DOT, JIS, ECER27 warning triangle, reflective film production requirements of BS6102 bicycle regulations are described in detail and the provisions of the sheeting, mandatory requirements and regulatory requirements. Retro-reflector production, resulting primarily through the development of mold, ingredients color, molding and complete with light and assembly processes. Reflectors were installed in accordance with the axle, defined as "the former white" side of the yellow "" After the red "loading specification vehicle loading or personal wear reflectors or reflective device, you can play the role of reflective warning as long as there is an exit lights source of positive exposure to the reflective object, the products back to the light, usually in the 300 meters will be reflected. general steam locomotive headlamp for 20000CD value or more, so the reflection of the light intensity is greater than 9600MCD value, so to play a warning or inform the rear of the motor vehicle driver who promptly know, keep a distance or brakes. especially now that foreign and domestic popular pedestrian reflectors or reflective ornaments, making the body was found or illuminate reflective in the remote hillside street lighting facilities or uncertain conditions effect , also known as "passive light." retro-reflector or reflective film's core technology is the electric mold core.
