Abstract

Une lentille est dotée d’un corps dont la forme permet de projeter de la lumière émanant d’une seule source compacte unique approximativement ponctuelle. La source projette la lumière sur une surface d’un panneau de signalisation orientée vers l’intérieur, et est montée en position adjacente à un bord du panneau de signalisation. Le corps de la lentille possède un axe principal et un axe latéral perpendiculaire à l’axe principal, de façon à ce qu’il puisse être monté de sorte que l’axe principal traverse un plan central du panneau de signalisation dans une première direction de celui-ci et à ce que l’axe latéral traverse le plan central du panneau de signalisation dans une deuxième direction latérale de celui-ci.
