MARKER OF ROAD CARPET WITH AMPLIFIED SIGNAL OF DAYTIME Russian patent published in 2010 - IPC E01F9/06 

FIELD: construction, road engineering.

SUBSTANCE: invention is related to marker of road carpet, which reflects and/or transmits light for identification of selected areas of traffic lane. Marker of road carpet comprises base for mounting onto support surface and lens made of semitransparent material, having back surface joined to base. Lens has at least one area of night time signal with multiple surfaces that reflect in reverse direction and are oriented for reflection of light from vehicle headlights back to vehicle, at the same time, at least one lens and base are arranged from polymer, having luminescent material in it, so that ambient light falling onto luminescent material induce radiation of photons via lenses for limitation of at least one area of daytime signal on lens, in which lens contains luminescent material in it. In another version marker comprises polymer base, having lower surface for assembly onto support surface and groove for front lens, having lower edge, substantially adjacent to lower surface of base, and upper edge is away from lower edge in backward direction so that groove for front lens is inclined at sharp angle relative to lower surface of base. Polymer lens has back surface, which is connected to groove for front lens of base, lens has at least one area of nighttime signal with multiple surfaces that reflect in reverse direction and are oriented for reflection of light from vehicle headlights back to vehicle, in which groove for front lens is arranged with multiple slots, back surface of lens is arranged with multiple ribs, which are inserted into groove slots for front lens, and is connected by means of ultrasonic welding with base so that inserted ribs and slots are melted integrally for limitation of integral polymer matrix.

EFFECT: provision of strong signal in nighttime and stronger signal in daytime.
