Definitions
- the invention relates to an illuminable outdoor advertising system with surfaces appearing dark and bright in daylight, the brightness of which reverses at night under the influence of artificial light which acts from the rear, so that surfaces which appear dark in daylight appear bright at night and surfaces which appear bright in daylight Appear dark at night, consisting of a box containing fluorescent tubes, a diffuser attached in front of the fluorescent tubes and a disc attached in front of the diffuser with the information to be displayed (information disc).
- Outdoor advertising systems of the type described above have so far only become known in the form of neon high-voltage systems (single letters, continuous letters, single characters, in which the fluorescent tube has the shape of the luminous element), in which the outermost pane is colored gray, so that a darker one in daylight Impression and at night a brighter impression is generated by artificial light acting from the back.
- the overall impression is unsatisfactory since the colors white and black cannot be achieved in this way and the reversal light / dark from day to night is not successful.
- the grid can be a line or preferably a point grid.
- the dark and light appearing areas can be colored, e.g. dark and light blue; they are preferably black and white.
- the preferred distance between the lens and the information disc also contributes to this.
- the design of the illuminated outdoor advertising system consisting of a box, fluorescent tubes, diffusing screen and information disc, corresponds to the usual practice.
- Glass or synthetic glass for example that made of polymethyl methacrylate or polycarbonate, is used as the material for the lens and information disc.
- High-fast pigmented printing inks are preferably used for printing (screen printing process).
- Outdoor advertising systems according to the invention with more than one information disc and a corresponding number of diffusing discs can be provided with different information on the information discs and can be designed, for example, as a cuboid with front and back or as a cube with four information discs, possibly rotatable.
- the information disks additionally contain information that appears day and night in the same brightness and color, these areas of the information disk are made in the known technique by simple back printing in the desired color and brightness.

Abstract
Description
Die Erfindung betrifft eine beleuchtbare Außenwerbeanlage mit bei Tageslicht dunkel und hell erscheinenden Flächen, deren Helligkeit bei Nacht unter Einfluß von Kunstlicht, das von der Rückseite einwirkt, sich umkehrt, so daß bei Tageslicht dunkel erscheinende Flächen bei Nacht hell und bei Tageslicht hell erscheinende Flächen bei Nacht dunkel erscheinen, bestehend aus einem Leuchtröhren enthaltenden Kasten, einer vor den Leuchtröhren angebrachten Streuscheibe und einer vor der Streuscheibe angebrachten Scheibe mit den darzustellenden Informationen (Informationsscheibe).The invention relates to an illuminable outdoor advertising system with surfaces appearing dark and bright in daylight, the brightness of which reverses at night under the influence of artificial light which acts from the rear, so that surfaces which appear dark in daylight appear bright at night and surfaces which appear bright in daylight Appear dark at night, consisting of a box containing fluorescent tubes, a diffuser attached in front of the fluorescent tubes and a disc attached in front of the diffuser with the information to be displayed (information disc).
Außenwerbeanlagen der vorstehend beschriebenen Art sind bisher nur in der Form von Neonhochspannungsanlagen (Einzelbuchstaben, durchgehende Schriften, Einzelzeichen, bei denen die Leuchtröhre die Form des leuchtenden Elements hat) bekannt geworden, bei denen die äußerste Scheibe grau eingefärbt ist, so daß bei Tageslicht ein dunklerer Eindruck und bei Nacht durch von der Rückseite einwirkendes Kunstlicht ein hellerer Eindruck erzeugt wird. Der Gesamteindruck ist unbefriedigend, da die Farbtöne Weiß und Schwarz so nicht erzielbar sind und die Umkehrung hell/dunkel vom Tag auf die Nacht nicht gelingt.Outdoor advertising systems of the type described above have so far only become known in the form of neon high-voltage systems (single letters, continuous letters, single characters, in which the fluorescent tube has the shape of the luminous element), in which the outermost pane is colored gray, so that a darker one in daylight Impression and at night a brighter impression is generated by artificial light acting from the back. The overall impression is unsatisfactory since the colors white and black cannot be achieved in this way and the reversal light / dark from day to night is not successful.
Es wurde überraschend gefunden, daß man Außenwerbeanlagen der eingangs genannten Art herstellen kann, wenn auf der Informationsscheibe bei Tageslicht hell erscheinende Flächen deckend hell und anschließend deckend dunkel und bei Tageslicht dunkel erscheinende Flächen mit einem Raster dunkel hinterdruckt werden.It has surprisingly been found that outdoor advertising systems of the type mentioned at the outset can be produced if, on the information disc, areas which appear bright in daylight are opaque and then opaque dark and areas which appear dark in daylight are back-printed with a dark screen.
Der Raster kann ein Linien- oder vorzugsweise ein Punktraster sein. Die dunkel und hell erscheinenden Flächen können farbig ausgeführt sein, z.B. dunkel- und hellblau; vorzugsweise werden sie schwarz und weiß ausgeführt.The grid can be a line or preferably a point grid. The dark and light appearing areas can be colored, e.g. dark and light blue; they are preferably black and white.
Weiter bevorzugte Ausführungsformen der Erfindung gehen aus den Unteransprüchen hervor. Die zusätzliche, helle bzw. weiße Hinterdruckung sorgt durch Reflexion zusammen mit der Streuscheibe, die vorzugsweise als Milchglasscheibe ausgeführt ist, für eine verbesserte Ausnutzung der Lichtmenge. Dazu trägt auch der bevorzugte Abstand von Streuscheibe und Informationsscheibe bei.Further preferred embodiments of the invention emerge from the subclaims. The additional, bright or white back printing, through reflection together with the lens, which is preferably designed as a frosted glass pane, ensures improved utilization of the amount of light. The preferred distance between the lens and the information disc also contributes to this.
Die Ausführung der beleuchtbaren Außenwerbeanlage aus Kasten, Leuchtröhren, Streuscheibe und Informationsscheibe entspricht im übrigen der gängigen Praxis. Als Material verwendet man für Streuscheibe und Informationsscheibe Glas oder Kunstglas, beispielsweise solches aus Polymethylmethacrylat oder Polycarbonat. Zur Bedruckung werden vorzugsweise hochechte pigmentierte Druckfarben verwendet (Siebdruckverfahren).The design of the illuminated outdoor advertising system, consisting of a box, fluorescent tubes, diffusing screen and information disc, corresponds to the usual practice. Glass or synthetic glass, for example that made of polymethyl methacrylate or polycarbonate, is used as the material for the lens and information disc. High-fast pigmented printing inks are preferably used for printing (screen printing process).
Erfindungsgemäße Außenwerbeanlagen mit mehr als einer Informationsscheibe und einer entsprechenden Anzahl Streuscheiben können mit unterschiedlichen Informationen auf den Informationsscheiben versehen sein und beispielsweise als Quader mit Vorder- und Rückseite oder als Würfel mit vier Informationsscheiben, eventuell drehbar, gestaltet sein.Outdoor advertising systems according to the invention with more than one information disc and a corresponding number of diffusing discs can be provided with different information on the information discs and can be designed, for example, as a cuboid with front and back or as a cube with four information discs, possibly rotatable.
Enthalten die Informationsscheiben zusätzlich Informationen, die Tag und Nacht in der gleichen Helligkeit und Farbe erscheinen, so sind diese Flächen der Informationsscheibe in bekannter Technik durch einfache Hinterdruckung in der gewünschten Farbe und Helligkeit ausgeführt.If the information disks additionally contain information that appears day and night in the same brightness and color, these areas of the information disk are made in the known technique by simple back printing in the desired color and brightness.
