Description

Selbstleuchtendes Verkehrszeichen Zur Kenntlichmachung der Verkehrsrichtung in der Dunkelheit sind selbstleuchtende Verkehrszeichen bekannt, bei denen auf einer Fläche .oder Scheibe Leuchtmassen aufgestrichen sind, die im Dunkeln selbst leuchten, wenn sie von Tages- oder elektrischem Licht vorher angestrahlt waren. Diese Verkehrszeichen sind jedoch nur kurzzeitig und in ganz beringer Entfernung sichtbar. Diesem Nachteil abzuhelfen, dient vorliegende Erfindung.Luminous traffic sign to indicate the direction of traffic self-illuminating traffic signs are known in the dark, with those on one Surface or disk luminous masses are painted on, which glow in the dark, if they were previously illuminated by daylight or electric light. These traffic signs However, they are only visible for a short time and at a very close distance. This disadvantage To remedy this, the present invention serves.

Gegenstand der Erfindung ist ein selbstleuchtendes Verkehrszeichen, welches aus einer mit Leuchtmasse bestrichenen Fläche und einem in ihrer Mitte angebrachten Rückstrahler besteht. Von den bekannten Anordnungen dieser Art unterscheidet -er sich dadurch, daß die Fläche mit lichtbrechenden -Kristallen oder .anderen dieselbe Wirkung erzielenden Stoffen besetzt wird. Infolge der lichtbrechenden Wirkung dieser Stoffe wird die Leuchtkraft der Leuchtmasse bedeutend erhöht. Das selbstleuchtende Verkehrszeichen ist somit auch in größerer Entfernung und über längere Dauer sichtbar.The subject of the invention is a self-illuminating traffic sign, which consists of a surface coated with luminous material and one attached in its center There is a reflector. It differs from the known arrangements of this type by the fact that the surface with refractive crystals or .other same Effect-producing substances is occupied. As a result of the light-refracting effect of this Substances, the luminosity of the luminous material is significantly increased. The self-luminous one Traffic signs are therefore visible at a greater distance and over a longer period of time.
