Abstract

This equipment has an image screen (2), the inner surface (7) of which is provided with a coating (8). The transparency of the image screen (2) is reduced by the coating (8) by 15 to 50 %. When the light source (3) is switched off, the coating (8) prevents the image on the film (4) from shining through the screen (2). By this means, the movement of the film (4) when it is changed, does not have a disturbing effect on the viewer. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Lichtreklamen- und Informations-Einrichtung bestehend aus einem Gehäuse mit mindestens einer Bildscheibe und einer im Gehäuse angeordneten Lichtquelle. Zwischen Lichtquelle und Bildschirm ist ein Diapositivfilm mit mindestens einem Bild oder einer Information angeordnet.The present invention relates to a light advertising and information device consisting of a housing with at least one image disc and a light source arranged in the housing. A slide film with at least one image or information is arranged between the light source and the screen.

Solche Lichtreklamen-Einrichtungen sind in verschiedenen Ausführungsformen bekannt, wovon eine zum Beispiel in der Schweizerischen Patentschrift Nr. 401 667 beschrieben ist. Im weiteren sind Lichtreklamen- und Informations-Einrichtungen bekannt, bei welchen das Reklamebild oder die Information für eine bestimmte Zeit beleuchtet wird und nachfolgend durch Ausschalten der Beleuchtung wieder verschwindet. Bei solchen Einrichtungen finden Diapositivfilme oder auch Papierplakate Verwendung. Dabei kann immer wieder das gleiche Bild gezeigt werden, oder es werden mehrere Bilder in Form einer Filmrolle zusammengehängt, wobei die Rolle während der Zeit in welcher die Lichtquelle ausgeschaltet ist jeweils um ein Bild weiter transportiert wird. Der Film, bzw. das Papierplakat, ist dabei hinter der Bildscheibe angeordnet und wird durch eine im Gehäuse angeordnete Lichtquelle beleuchtet.Such light advertising devices are known in various embodiments, one of which is described, for example, in Swiss Patent No. 401 667. In addition, light advertising and information devices are known in which the advertising image or the information is illuminated for a certain time and subsequently disappears again by switching off the lighting. In such facilities, slide films or paper posters are used. The same image can be shown again and again, or several images are connected in the form of a film roll, the roll being transported one frame each time the light source is switched off. The film or the paper poster is arranged behind the image disk and is illuminated by a light source arranged in the housing.

Die bekannten Ausführungen solcher Einrichtungen haben den Nachteil, dass bei ausgeschalteter Lichtquelle das Bild durch die Bildscheibe undeutlich erkannt werden kann. Besonders störend wirkt sich dies aus, wenn der Film transportiert wird, um das nächste Bild in die Beleuchtungsposition zu bringen. Insbesondere bei Werbebildern wird dadurch der Wirkungseffekt zwischen der leeren Bildscheibe und dem aufleuchtenden Werbebild reduziert.The known designs of such devices have the disadvantage that when the light source is switched off, the image can be recognized indistinctly by the image disk. This is particularly disruptive when the film is transported to bring the next image into the lighting position. In particular in the case of advertising images, this reduces the effect of the effect between the empty image pane and the illuminated advertising image.

Der Erfindung liegt die Aufgabe zu Grunde, eine Einrichtung zu schaffen, bei welcher das Bild hinter der Bildscheibe bei ausgeschalteter Lichtquelle keinen störenden Einfluss auf den Betrachter hat. Zudem soll auch die störende Wirkung des durchlaufenden Bildes, bzw. Filmes, beim Bildwechsel vermieden werden. Diese Aufgabe wird dadurch gelöst, dass an der Innenfläche der Bildscheibe eine Beschichtung angebracht und die Lichtdurchlässigkeit der beschichteten Scheibe um 15 bis 50 % reduziert ist. Die Beschichtung kann dabei aus einer Kunststoffolie bestehen, welche mindestens einseitig mit einem optisch klaren Metallfilm versehen ist. Anstelle der Kunststoffolie können aber auch fein verteilte Pünktchen aus reflektierendem Material, z.B. weisser Farbe oder ähnlicher Art, auf die Innenfläche der Bildscheibe aufgebracht werden, wodurch das gewünschte Resultat ebenfalls erreicht werden kann. In weiterer Ausgestaltung der Erfindung kann die Beschichtung aus einem direkt auf die Innenfläche der Bildscheibe aufgedampften Metallfilm bestehen.The invention is based on the object of providing a device in which the image behind the image pane with the light source switched off has no disruptive influence on the viewer. In addition, the disruptive effect of the moving image or film should be avoided when changing the image. This object is achieved in that a coating is applied to the inner surface of the image pane and the light transmission of the coated pane is reduced by 15 to 50%. The coating can consist of a plastic film, which is provided on at least one side with an optically clear metal film. Instead of the plastic film, however, finely distributed dots made of reflective material, for example white color or a similar type, can also be applied to the inner surface of the image pane, as a result of which the desired result can also be achieved. In a further embodiment of the invention, the coating can consist of a metal film vapor-deposited directly onto the inner surface of the image pane.

Beim Betrieb der erfindungsgemässen Einrichtung befindet sich der Diapositivfilm mit dem Werbebild oder der Information in farbiger oder schwarz/weisser Ausführung zwischen der Bildscheibe und der Lichtquelle, innerhalb des Gehäuses. Wird die Lichtquelle eingeschaltet, so wird das Bild oder die Information durch die Bildscheibe von aussen klar sichtbar. Bei ausgeschalteter Lichtquelle ist es dagegen nicht möglich, das Bild zu erkennen, da die reduzierte Durchlässigkeit der beschichteten Scheibe die Durchsicht in den dunklen Kasten verhindert. Auch der rollende Film kann von aussen nicht erkannt werden, und die Bildscheibe erscheint deshalb bei ausgeschalteter Lichtquelle als gleichmässig gefärbte ruhige Fläche. Anstelle des Diapositivfilmes kann auch ein elektronisches Anzeigefeld oder ein Bildschirm Verwendung finden.When the device according to the invention is in operation, the slide film with the advertising image or the information in colored or black / white design is located between the image disc and the light source, inside the housing. If the light source is switched on, the image or information is clearly visible from the outside through the image pane. However, when the light source is switched off, it is not possible to recognize the image, since the reduced permeability of the coated pane prevents the dark box from being seen through. Even the rolling film cannot be recognized from the outside, and the image disc therefore appears as an evenly colored, calm surface when the light source is switched off. Instead of the slide film, an electronic display panel or a screen can also be used.

Eine zusätzliche Verbesserung der Bildqualität und der Wirkung der leeren Bildfläche ergibt sich, wenn für die Bildscheibe reflexarmes Glas verwendet wird. Dies kann dadurch erreicht werden, dass die äussere Fläche der Bildscheibe schwach geätzt ist. Dies hat zur Folge, dass auf der Bildscheibe keine unerwünschten Spiegelungen von fremden Objekten auftreten und gleichzeitig die Farbwirkung bei gefärbtem Glas oder Beschichtung gleichmässiger ist. Die Aetzung darf dabei nur so stark sein, dass das mit Abstand zur Bildscheibe angeordnete Bild noch in der gewünschten Weise sichtbar ist.An additional improvement in the image quality and the effect of the empty image area results if low-reflection glass is used for the image pane. This can be achieved by weakly etching the outer surface of the image disk. The result of this is that there are no undesired reflections from foreign objects on the image disc and at the same time the color effect is more uniform with colored glass or coating. The etching may only be so strong that the image spaced from the image disc is still visible in the desired way.

In weiterer Ausgestaltung der Erfindung wird die Beschichtung so ausgeführt, dass das von aussen einfallende Licht so stark reflektiert wird, dass die Bildscheibe bei abgeschalteter Licht- 'quelle einen Spiegel bildet. Diese Ausführungsform hat den zusätzlichen Vorteil, dass die Einrichtung bei ausgeschalteter Lichtquelle als Spiegelfläche benutzt werden kann. Dadurch eröffnen sich weitere Einsatzmöglichkeiten für derartige Geräte. Beim Einsatz der Bildscheibe als Spiegelfläche hat es sich auch als vorteilhaft erwiesen, das Werbebild oder die Information nur auf einer Teilfläche der Bildscheibe erscheinen zu lassen. Dadurch lassen sich wiederum besondere Effekte erreichen, indem ein Teil der Bildscheibe dauernd als Spiegel und ein anderer Teil abwechselnd als Spiegel und als Bild erscheint. Die Bildscheibe kann auch in eine Wand eingebaut sein.In a further embodiment of the invention, the coating is carried out in such a way that the light incident from the outside is reflected so strongly that the image disk forms a mirror when the light source is switched off. This embodiment has the additional advantage that the device can be used as a mirror surface when the light source is switched off. This opens up further possible uses for such devices. When using the image disc as a mirror surface, it has also proven advantageous to have the advertising image or the information appear only on a partial surface of the image disc. This in turn allows special effects to be achieved in that one part of the image disc constantly appears as a mirror and another part alternately as a mirror and as an image. The image disc can also be built into a wall.

Ein Ausführungsbeispiel der Erfindung ist nachstehend anhand der Zeichnung näher erläutert. Es zeigt:

  • Fig. 1 einen Schnitt durch eine rechteckförmige Lichtreklamen- und Informations-Einrichtung
An embodiment of the invention is explained below with reference to the drawing. It shows:
  • Fig. 1 shows a section through a rectangular light advertising and information device

Die Lichtreklamen- und Informations-Einrichtung besteht aus einem Gehäuse 1, welches mindestens an einer Seite mit einer Bildscheibe 2 versehen ist. Im Innern des Gehäuses 1 befindet sich eine Lichtquelle 3, z.B. in der Form einer Leuchtröhre. Im Gehäuse 1 ist zwischen der Bildscheibe 2 und der Lichtquelle 3 ein Diapositivfilm angeordnet, auf welchem das Reklamebild oder die Information schwarz/weiss oder farbig abgebildet ist. Die Innenfläche 7 der Bildscheibe 2 ist mit einer Beschichtung 8 versehen. Diese Beschichtung besteht im beschriebenen Beispiel aus einem hochtransparenten Polyesterfilm, welcher mit einer optisch klaren Aluminium-Bedampfung versehen ist. Dieser Polyester film ist auf die Innenfläche 7 der Bildscheibe 2 aufgeklebt. Durch den aufgeklebten Film wird die Lichtdurchlässigkeit der Scheibe 2 um ca. 40 % reduziert. Diese Lichtreduktion wirkt sich jedoch nur auf von aussen cinfallondes Licht aus. Die Lichtquelle 3 ist so stark ausgestaltet, dass das Bild auf dem Diapositivfilm 4, für Betrachter ausserhalb des Gerätes 1, bei eingeschalteter Lichtquelle 3 klar und in voller Farbqualität erscheint. Die Aussenfläche 9 der Bildscheibe 2 ist schwach geätzt, um unerwünschte Reflexionen von sich ausserhalb des Gerätes befindlichen Objekten zu verhindern. Als Grundlage für die Bildscheibe 2 wird ein handelsübliches reflexarmes Glas verwendet. Im weiteren weist das Gerät eine Steuer- und Antriebseinrichtung 10 auf, welche beim Einsatz von Filmrollen für den Transport des Filmes und die Steuerung der Beleuchtung vorprogrammiert wird.The light advertising and information device consists of a housing 1 which is provided with a picture disc 2 on at least one side. Inside the housing 1 there is a light source 3, for example in the form of a fluorescent tube. A slide film is arranged in the housing 1 between the image plate 2 and the light source 3, on which the advertising image or the information is shown in black / white or in color. The inner surface 7 of the image disc 2 is provided with a coating 8. In the example described, this coating consists of a highly transparent polyester film which is provided with optically clear aluminum vapor deposition. This polyester film is glued to the inner surface 7 of the image disc 2. The translucent film reduces the light transmission of the pane 2 by approximately 40%. However, this reduction in light only affects light from outside that is cinfallond. The light source 3 is designed so strong that the image on the slide film 4, for viewers outside of the device 1, at switched light source 3 appears clear and in full color quality. The outer surface 9 of the image disc 2 is slightly etched in order to prevent undesired reflections from objects located outside the device. A commercially available low-reflection glass is used as the basis for the image pane 2. Furthermore, the device has a control and drive device 10, which is preprogrammed when using film rolls for the transport of the film and the control of the lighting.

Beim Betrieb des Gerätes wird die Lichtquelle 3 für eine bestimmte Zeit eingeschaltet, wodurch der Bildausschnitt des Diapositivfilmes 4 hinter der Bildscheibe 2 für einen Betrachter ausserhalb des Gerätes sichtbar wird. Nach einer bestimmten vorgewählten Zeit wird die Lichtquelle 3 ausgeschaltet, und der Diapositivfilm 4 wird um ein ganzes Bild weiter transportiert. Dabei kann der Film 4 sowohl von der Rolle 5 zur Rolle 6, wie auch umgekehrt, transportiert werden. Sobald sich das neue Bild auf dem Film 4 hinter der Bildscheibe 2 befindet wird die Lichtquelle 3 erneut eingeschaltet, und das neue Reklamebild oder die neue Information ist für den Betrachter sichtbar. Während des Transportes des Films und bei ausgeschalteter Lichtquelle 3 verhindert die Beschichtung 8, bzw. die aufgeklebte Folie die Durchsicht durch die Bildscheibe 2 in den dunklen Raum innerhalb des Gehäuses 1. Dadurch kann weder das Bild auf dem Film 4 noch der allfällig laufende Film 4 selbst erkannt werden.During operation of the device, the light source 3 is switched on for a certain time, as a result of which the image section of the slide film 4 behind the image pane 2 is visible to an observer outside the device. After a certain preselected time, the light source 3 is switched off, and the slide film 4 is transported one full image. The film 4 can be transported both from the roll 5 to the roll 6 and vice versa. As soon as the new image on the film 4 is behind the image pane 2, the light source 3 is switched on again and the new advertisement image or the new information is visible to the viewer. During the transport of the film and with the light source 3 switched off, the coating 8 or the glued-on film prevents viewing through the picture pane 2 into the dark space inside the housing 1. As a result, neither the picture on the film 4 nor the possibly running film 4 can be recognized yourself.
