Die Erfindung betrifft ein beieuchtbares Leuchtkennzeichen mit einer Symbolanzeige.The invention relates to an illuminated license plate with a symbol display.

Leuchtwegsysteme sind bekannt zur Verwendung als Orientierungshilfe für Notfälle in gefährdeten Räumen in z. B. Schiffen, Gebäuden, Bahnhöfen, Flugzeugen und dgl.. Hier werden z. B. passive Leuchtwegsysteme eingesetzt, die eine streifen- und plattenförmige Schicht nachleuchtenden Materials aufweisen. Dieses Leuchtwegsysteme haben den Nachteil, daß die Leuchtintensität begrenzt ist und die Nachleuchtfähigkeit nach einem gewissen Zeitraum erlischt. Es werden deshalb auch aktiv leuchtende Leuchtwegsysteme eingesetzt, bei denen die Leuchtwege durch Leuchtanzeigen wie z. B. lichtemittierende Dioden gebildet werden, die durch Streifen aus einem lichtdurchlässigen Material abgedeckt sind. Der Nachteil dieser bekannten aktiven Leuchtwegsysteme besteht darin, daß sie im Einsatz unflexibel sind, da sie nur ein- oder ausgeschaltet werden können. Bei auf dem Boden angeordneten Systemen besteht ein weiterer Nachteil darin, daß die Abdeckprofile der Leuchtstreifenprofile, die aus Polyvenylchlorid bestehen, relativ schnell durch Begehen zerkratzt werden, wodurch Lichtveriuste entstehen. Es ist auch bekannt, nachleuchtende oder beleuchtbare Leuchtkennzeichen als Einzelelemente einzusetzen. Die bekannten beleuchtbaren Leuchtkennzeichen haben aufgrund ihrer graphischen Gestaltung den Nachteil, daß sie eine Mehrzahl von Lichtquellen wie z. B. lichtemittierende Dioden erfordern, um das anzuzeigende Symbol optisch wirksam werden zu lassen. Hierdurch ist der Energieverbrauch relativ hoch, was in Notfällen, wenn nur noch eine Notstromversorgung einsatzbereit ist, kritisch werden kann, da die Leistungsfähigkeit der Notstrombatterien begrenzt ist.Light path systems are known for use as orientation aids for emergencies in endangered areas, e.g. ships, buildings, train stations, airplanes, etc. Passive light path systems are used here, for example, which have a strip and plate-shaped layer of luminescent material. These light path systems have the disadvantage that the light intensity is limited and the luminescence ability expires after a certain period of time. Actively luminous light path systems are therefore also used, in which the light paths are formed by light displays such as light-emitting diodes, which are covered by strips of a translucent material. The disadvantage of these known active light path systems is that they are inflexible in use, since they can only be switched on or off. A further disadvantage of systems arranged on the floor is that the cover profiles of the light strip profiles, which are made of polyvinyl chloride, are scratched relatively quickly by walking on them, which causes light losses. It is also known to use luminescent or illuminated signs as individual elements. Due to their graphic design, the known illuminated signs have the disadvantage that they require a number of light sources such as light-emitting diodes in order to make the symbol to be displayed visually effective. This means that energy consumption is relatively high, which can become critical in emergencies when only an emergency power supply is available, as the performance of the emergency power batteries is limited.

Die Aufgabe der Erfindung besteht darin, ein gattungsgemäßes Leuchtkennzeichen so auszubilden, daß im Bedarfsfall das Symbol unter Energieeinsparung deutlich angezeigt werden kann.The object of the invention is to design a generic illuminated sign in such a way that, if necessary, the symbol can be clearly displayed while saving energy.

Erfindungsgemäß erfolgt die Lösung der Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1. Vorteilhafte Ausgestaltungen der Erfindung werden in den abhängigen Ansprüchen beschrieben.According to the invention, the object is achieved by the characterizing features of claim 1. Advantageous embodiments of the invention are described in the dependent claims.

Nach der Erfindung ist es somit möglich, die Anzahl der bei bekannten Leuchtkennzeichen erforderlichen lichtemittierenden Dioden wesentlich zu verringern, so daß der Energieverbrauch geringer wird.According to the invention, it is thus possible to significantly reduce the number of light-emitting diodes required in known illuminated signs, so that energy consumption is reduced.

Die Erfindung wird nachstehend anhand der in den Zeichnungen schematisch dargestellten Ausführungsbeispielen näher beschrieben. Es zeigtThe invention is described in more detail below with reference to the embodiments shown schematically in the drawings. It shows

Fig. 1 ein erfindungsgemäßes Leuchtkennzeichen in einer perspektivischen Ansicht Fig. 2 das Leuchtkennzeichen nach Fig. 1 in einer schematischen Queransicht im Schnitt Fig. 3 das Leuchtkennzeichen nach Fig. 1 in einer Ansicht von vornFig. 1 shows an illuminated license plate according to the invention in a perspective view Fig. 2 shows the illuminated license plate according to Fig. 1 in a schematic cross-sectional view Fig. 3 shows the illuminated license plate according to Fig. 1 in a view from the front

Fig. 4 drei weitere beispielhafte Ausgestaltungen eines Leuchtkennzeichens in der bis 6 DraufsichtFig. 4 three further exemplary designs of an illuminated license plate in the to 6 top view

Das in Fig. 1 dargestellte Leuchtkennzeichen 1 besteht aus einer aus Acryl bestehenden Kunststoffolie 3, an deren Unterseite 4 das abzubildende Symbol durch ausgefräste Nuten ausgebildet ist. Es ist aber auch möglich, das abzubildende Symbol auf die Kunststoffolie 3 aufzudrucken. An der einen Seitenkante 6 sind vier lichtemittierende Dioden 7 angeordnet. Das Leuchtkennzeichen 1 kann durch eine Abdeckkappe 10 oder 11 abgedeckt werden. Die Abdeckkappe 10 weist seitlich Lippen 12 auf, um einen angrenzenden Boden- oder Wandbelag abzudecken. An der Unterseite 14 der Abdeckkappen 10, 11 sind seitlich Klemmstege 13 angeordnet, mittels derer die Abdeckkappen 10, 11 mit dem in Fig. 2 dargestellten Rahmen 8 in lösbaren Wirkeingriff bringbar sind.The illuminated sign 1 shown in Fig. 1 consists of a plastic film 3 made of acrylic, on the underside 4 of which the symbol to be displayed is formed by milled grooves. However, it is also possible to print the symbol to be displayed on the plastic film 3. Four light-emitting diodes 7 are arranged on one side edge 6. The illuminated sign 1 can be covered by a cover cap 10 or 11. The cover cap 10 has lips 12 on the side in order to cover an adjacent floor or wall covering. Clamping webs 13 are arranged on the underside 14 of the cover caps 10, 11, by means of which the cover caps 10, 11 can be brought into releasable operative engagement with the frame 8 shown in Fig. 2.

Fig. 2 zeigt eine Queransicht des Leuchtkennzeichens nach Fig. 1. Die Kunststoffolie 3, die aus Acryl wie z. B. einem Polymethacrylat besteht, in das fluoresierende Pigmente mit ggf.Fig. 2 shows a cross-section of the luminous sign according to Fig. 1. The plastic film 3, which is made of acrylic such as a polymethacrylate, into which fluorescent pigments are mixed with, if necessary,

lichtbrechenden Eigenschaften eingelagert sind, ist in einem Rahmen 8 angeordnet, der auch die an der einen Seitenkante 6 der Kunststoffolie 3 befindlichen lichtemittierenden Dioden 7 einfaßt. An der Unterseite 4 der Kunststoffolie 3 sind Nuten 5 ausgefräst, die dem abzubildenden Symbol entsprechen. Aufgrund der Eigenschaften der Kunststoffolien wird im Bereich der Nuten 5 das von den lichtemittierenden Dioden 7 emittierte Licht im Winkel von 90° Grad zur äußeren Oberfläche der Kunststoffolie 3 abgelenkt, so daß auf dieser das abzubildende Symbol sichtbar wird.light-refracting properties are embedded, is arranged in a frame 8, which also encloses the light-emitting diodes 7 located on one side edge 6 of the plastic film 3. Grooves 5 are milled out on the underside 4 of the plastic film 3, which correspond to the symbol to be displayed. Due to the properties of the plastic films, in the area of the grooves 5, the light emitted by the light-emitting diodes 7 is deflected at an angle of 90° to the outer surface of the plastic film 3, so that the symbol to be displayed becomes visible on it.

Wie in Fig. 3 dargestellt ist es möglich, an einander gegenüberliegenden Seitenkanten des Leuchtkennzeichens 1 Stromanschlüsse 9 vorzusehen, so daß das Leuchtkennzeichen 1 in geschlossene aktiv leuchtende Leuchtwegsysteme integriert werden kann.As shown in Fig. 3, it is possible to provide power connections 9 on opposite side edges of the illuminated sign 1, so that the illuminated sign 1 can be integrated into closed actively illuminated light path systems.

Die Figuren 4 bis 6 zeigen weitere mögliche Ausführungsformen von Leuchtkennzeichen mit unterschiedlichen anzuzeigenden Symbolen. Es sind jedoch auch weitere Ausführungsformen von Symbolen durch Leuchtkennzeichen 1 darstellbar.Figures 4 to 6 show further possible embodiments of illuminated indicators with different symbols to be displayed. However, other embodiments of symbols can also be represented by illuminated indicator 1.
