Abstract

La présente invention concerne un réflecteur servant au marquage d'une surface de roulement. Le réflecteur est caractérisé en ce que : une base est fixée sur une installation routière ou sur une surface de roulement ; un corps émetteur de lumière constitué d'un matériau transparent est monté sur la base ; et une couche réfléchissante est formée au niveau d'une surface de contact entre le corps émetteur de lumière et la base, de façon à réfléchir la lumière incidente sur le corps émetteur de lumière. Le réflecteur servant au marquage d'une surface de roulement selon la présente invention peut être fixé à une ligne centrale ou à une ligne de voie de façon à achever la construction, et peut être facilement fixé à la ligne centrale ou à la ligne de voie sans nécessiter l'installation d'un étai séparé au niveau d'une glissière de sécurité ou d'une installation routière, permettant ainsi un travail facile. En outre, le réflecteur servant au marquage d'une surface de roulement selon la présente invention est structuré de façon à ce que la couche réfléchissante formée sur le corps émetteur de lumière soit dissimulée vers l'intérieur de la base, et une surface exposée du corps émetteur de lumière est exposée depuis l'extérieur de la base, augmentant de ce fait l'efficacité de la réflexion.
