Luminous horizontal roadway marking strips, and method and devices for forming such luminous horizontal roadway markings

摘要

The marking strip includes photovoltaic cells (1) placed inside of retroreflecting prisms (2) which receive by day the sun energy and by night that one of the headlights of the approaching vehicles, and convert it into electric energy. Said electric energy charges long life micro-storage-batteries (7) which are placed in a control box (5).Light emitting diodes (leds) are distributed along the strip inside of transparent protruding bodies.There are also foreseen catadioptric prisms placed on the strip. The whole having a permanent active marking function, which may be excited by the approaching traffic.One of the leds may change its color following the presence of liquid crystals, in order to forewarn the motorist of the possible slippery condition of the road surface.
