Description

Die Erfindung betrifft eine Leuchtbox mit einem Profilrahmen, einer Rückwand, innenseitig an dieser befestigten Leuchtkörpern sowie mit einem vorderseitigen transparenten Bild, das am Profilrahmen entlang seines Umfangs wegnehmbar fixierbar ist.The invention relates to a light box with a profile frame, a rear wall, on the inside of this fixed luminous bodies and with a front-side transparent image, which is removably fixed to the profile frame along its circumference.

Solche Leuchtboxen sind bekannt und werden für Reklamezwecke oder für Präsentation von Bild-Sujets, wie Landschaften, Tieren oder dergleichen verwendet.Such light boxes are known and are used for advertising purposes or for presentation of image subjects, such as landscapes, animals or the like.

Bei einem Reklameleuchtkasten gemäss der Druckschrift CH-A-668 822 ist eine röhrenförmige Lichtquelle vorgesehen, die wenigstens ein Bereich ihres Umfangs mit einer sich in entgegengesetzten Umfangsrichtungen im gleichen Sinne ändernden Helligkeitsabschirmung versehen ist. Die Lichtdurchlässigkeit ist jeweils in Längsrichtung der röhrenförmigen Lichtquelle konstant und soll von einem minimalen Wert aus in beiden Umfangsrichtungen gleichmässig zunehmen. Damit soll ein in kurzer Entfernung von der röhrenförmigen Lichtquelle befindliches Transparentbild wenigstens näherungsweise gleichförmig ausgeleuchtet werden. Es ist aber relativ aufwendig, die röhrenförmige Lichtquelle mit den entsprechenden Abschirmungen zu versehen.In a billboard according to the publication CH-A-668 822 a tubular light source is provided which is at least one area its circumference is provided with a brightness shield changing in the same direction in opposite circumferential directions. The light transmittance is constant in each case in the longitudinal direction of the tubular light source and should increase uniformly in both circumferential directions from a minimum value. This is intended to illuminate a translucent image located at a short distance from the tubular light source at least approximately uniformly. However, it is relatively expensive to provide the tubular light source with the corresponding shields.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Leuchtbox derart zu verbessern, dass mit ihr eine optimale Ausleuchtung eines transparenten Bildes erzielt wird, und dass ferner die Leuchtbox für eine mobile Verwendung leicht transportierbar ausgeführt ist.The invention is based on the object to improve a lightbox so that with it an optimal illumination of a transparent image is achieved, and further that the light box is designed for mobile use easily transportable.

Diese Aufgabe ist erfindungsgemäss nach den Merkmalen des Anspruchs 1 gelöst.This object is achieved according to the features of claim 1.

Mit der Bildung der Leuchtkörper aus LED-Lampen, die annähernd über die gesamte Höhe und Breite des Profilrahmens in Reihen in bestimmten Abständen zueinander angeordnet sind, wird eine optimale Beleuchtung des transparenten Bildes erzielt, bei der das Bild ohne Schattenflecken und gleichmässig über seine gesamte Fläche belichtet wird.With the formation of the LED lamp filaments, arranged in spaced rows approximately over the entire height and width of the profile frame, optimum illumination of the transparent image is achieved, leaving the image without shadow spots and uniform over its entire surface is exposed.

Sehr vorteilhaft sind die die LED-Lampen reihenweise an Leiterleisten in den bestimmten Abständen zueinander als vorgefertigte Einheiten montiert, wobei diese Leiterleisten innenseitig an der Rückwand der Leuchtbox befestigt sind.It is very advantageous that the LED lamps are mounted row by row on conductor strips at predetermined distances from each other as prefabricated units, these conductor strips being fastened on the inside to the rear wall of the light box.

Für die mobile Ausgestaltung der Leuchtbox sind der Profilrahmen sowie die Rückwand zwecks einfacherer Transportfähigkeit gemeinsam zusammenklappbar ausgebildet. Damit kann die Leuchtbox im zugeklappten Zustand in einer Tasche versorgt werden und sie lässt sich damit durch nur eine Person leicht transportieren und auch in einem kurzen Zeitraum wieder aufstellen.For the mobile design of the light box of the profile frame and the rear wall are together for the purpose of easier transportability collapsible educated. Thus, the light box can be supplied in the closed state in a bag and it can be easily transported by one person and set up again in a short period of time.

Die Erfindung sowie weitere Vorteile derselben sind nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert. Es zeigt:

Fig. 1 und Fig. 2 zeigen eine Leuchtbox 10 mit einem äusseren Profilrahmen 12, einer Rückwand 11 sowie innenseitig an dieser befestigten Leuchtkörpern. Dieser Profilrahmen 12 kann beispielsweise mit einer Höhe von 2 m und einer Breite von 800 mm dimensioniert sein. Diese Abmessungen können aber je nach Anwendung beliebig variiert werden. Fig. 1 and Fig. 2 show a light box 10 with an outer profile frame 12, a rear wall 11 and the inside of this attached luminous bodies. This profile frame 12 may be dimensioned, for example, with a height of 2 m and a width of 800 mm. However, these dimensions can be varied as desired depending on the application.

Gemäss Fig. 2 ist die Rückwand 11 in Längsnuten 23 des Profilrahmens 12 gehalten, hingegen vorderseitig am Profilrahmen 12 ist ein transparentes Bild 13 entlang seines gesamten Umfangs wegnehmbar fixiert. Dieses Bild 13 ist vorzugsweise sowohl bei den Längs- als auch bei den Breitseiten des Profilrahmens 12 in nach vorne geöffnete Profilnuten 14 eingesteckt. Zu diesem Zwecke sind in diesen Profilnuten 14 auf bekannte Weise Kederleisten 17 positioniert, zwischen diese und der äusseren Wand der Profilnuten 14 die Endseiten 13' des Bildes 13 gehalten sind. Durch die entstehende Biegekraft des Bildes auf die Kederleisten 17 wird ein Verklemmen und damit ein dauerhaftes Spannen des Bildes erzielt. Diese Leuchtbox 10 bildet damit einen geschlossen Kasten, damit das erzeugte Licht der Leuchtkörper einzig durch das Bild nach aussen durchdringen kann.According to Fig. 2 the rear wall 11 is held in longitudinal grooves 23 of the profile frame 12, whereas on the front side on the profile frame 12, a transparent image 13 is fixed removably along its entire circumference. This image 13 is preferably inserted both in the longitudinal and in the broad sides of the profile frame 12 in the front open profile grooves 14. For this purpose, in this profile grooves 14 Kederleisten 17 are positioned in a known manner, between these and the outer wall of the profile grooves 14, the end sides 13 'of the image 13 are held. Due to the resulting bending force of the image on the welt strips 17 jamming and thus a permanent tensioning of the image is achieved. This light box 10 thus forms a closed box, so that the light generated by the light body can penetrate only through the image to the outside.

Erfindungsgemäss sind die Leuchtkörper aus LED-Lampen 15 gebildet, die annähernd über die gesamte Breite und Höhe des Profilrahmens 12 in Reihen 15' in bestimmten Abständen b, h zueinander angeordnet sind.According to the invention, the luminous bodies are formed from LED lamps 15, which are arranged approximately over the entire width and height of the profiled frame 12 in rows 15 'at specific distances b, h relative to one another.

Diese reihenweise angeordneten LED-Lampen 15 sind an Leiterleisten 16 in den bestimmten Abständen b zueinander als vorgefertigte Einheiten montiert, wobei sie innenseitig an der Rückwand 11 befestigt sind. Diese Leiterleisten 16 erstrecken sich jeweils horizontal über die Breite des Profilrahmens 12 und sie sind übereinander jeweils mit dem bestimmten Abstand h zueinander angeordnet. Diese Leiterleisten 16 könnten im Prinzip auch vertikal verlaufen und nebeneinander mit den Abständen b an der Innenseite der Rückwand 11 befestigt sein.These rows arranged LED lamps 15 are mounted on ladder rails 16 in the specific distances b to each other as prefabricated units, wherein they are fastened on the inside to the rear wall 11. These conductor strips 16 each extend horizontally across the width of the profile frame 12 and they are arranged one above the other in each case with the specific distance h to each other. These conductor strips 16 could in principle also run vertically and be fastened next to each other with the distances b on the inside of the rear wall 11.

Die als einzelne runde linsenförmige Spotlampen ausgebildeten LED-Lampen 15 weisen einen solchen Abstand zu dem transparenten Bild 13 auf, dass die von den LED-Lampen 15 erzeugten Lichtkegel 18 das Bild ohne Überschneidungen annähernd vollflächig beleuchten.The LED lamps 15 designed as individual round lens-shaped spot lamps have such a distance from the transparent image 13 that the light cones 18 generated by the LED lamps 15 illuminate the image almost completely over the entire area without overlapping.

Es sind gemäss Fig. 1 zwei quer zu den Leiterleisten 16 verlaufende Kabel 20, 21 vorgesehen, welche via Leitungen in den einzelnen Leiterleisten 16 mit den LED-Lampen 15 durch eine Serien- oder Parallelschaltung verbunden sind. Ein nicht näher gezeigtes Netzkabel ist aussenseitig des Profilrahmens 12 an das Stromnetz anschliessbar. Das Netzkabel ist vorzugsweise an einen Netzteil angeschlossen, welcher die Netzspannung auf eine Niedrigspannung vorzugsweise auf 12 Volt transformiert und durch die Kabel 20, 21 und Leitungen in den Leiterleisten 16 die LED-Lampen speist. Mit Vorteil ist im Netzteil ein Dimmer integriert, damit die Lichtstärke je nach Bedarf variiert werden kann.They are according to Fig. 1 two extending transversely to the conductor bars 16 extending cable 20, 21, which are connected via lines in the individual conductor bars 16 with the LED lamps 15 by a series or parallel connection. A not shown in detail power cord is outside of the profile frame 12 connected to the mains. The power cord is preferably connected to a power supply, which transforms the mains voltage to a low voltage preferably to 12 volts and fed by the cables 20, 21 and lines in the conductor bars 16, the LED lamps. Advantageously, a dimmer is integrated in the power supply, so that the light intensity can be varied as needed.

Diese erfindungsgemässe Leuchtbox kann wie ein Bild wegnehmbar an eine Wand befestigt werden. Sie könnte auch in eine Wand oder dergleichen eingemauert sein.This light box according to the invention can be removably attached to a wall like an image. It could also be walled in a wall or the like.

Die Leuchtbox 10 gemäss Fig. 1 ist im Rahmen der Erfindung mobil ausgestaltet, damit sie manuell von nur einer Person beispielsweise in einen Präsentationsraum getragen, dort in Kürze aufgebaut, mit dem Stromnetz verbunden und anschliessend das Bild beleuchtet wird.The light box 10 according to Fig. 1 is designed to be mobile within the scope of the invention so that it is carried manually by only one person, for example, in a presentation room, built there shortly, connected to the mains and then the image is illuminated.

Zu diesem Zwecke der Mobilität sind der Profilrahmen 12 sowie die Rückwand 11 gemeinsam zusammenklappbar ausgebildet, wobei die Rückwand 11 dazu mit wenigstens einer Schwenkachse 24 versehen ist und der Profilrahmen 12 in der gleichen Ebene beidseitig Trennstellen 12' aufweist. Diese Schwenkachse 24 ist vorteilhaft in der Mitte der Leuchtbox 10 vorgesehen, damit letztere in zwei gleich grosse Hälften zusammengelegt werden kann, wobei in Fig. 1 von der unteren Hälfte der Leuchtbox lediglich ein Teil veranschaulicht ist. In der zugeklappten Stellung kann sie beispielsweise in eine Tragtasche mit Rollen gelegt und wie eine Rollwagen gezogen werden.For this purpose, the mobility of the profile frame 12 and the rear wall 11 are formed together collapsible, the rear wall 11 is provided with at least one pivot axis 24 and the profile frame 12 in the same plane on both sides separating points 12 '. This pivot axis 24 is advantageously provided in the middle of the light box 10, so that the latter can be merged into two equal halves, wherein in Fig. 1 from the lower half of the light box only a part is illustrated. In the closed position, for example, it can be placed in a carrier bag with rollers and pulled like a trolley.

Die Rückwand 11 ist aus einer biegsamen Kunststoffwandung sowie aus zumindest ein-, vorzugsweise beidseitig an dieser angebrachten Metallblechen hergestellt, was nicht näher veranschaulicht ist. Die Metallbleche sind jeweils bei der die Schwenkachse 24 bildenden Faltstelle ausgespart bzw. unterbrochen, damit die Kunststoffwandung dort umgebogen werden kann. Sie ist aus einer Polypropylen-Platte oder einem ähnlichen Kunststoff hergestellt und die Metallbleche sind insbesondere aus Aluminium gefertigt und mit Ausnahme bei der Faltstelle beidseitig ganzflächig an dieser Platte verklebt.The rear wall 11 is made of a flexible plastic wall and made of at least one, preferably both sides of this attached metal sheets, which is not illustrated in detail. The metal sheets are each recessed or interrupted at the folding axis 24 forming fold, so that the plastic wall can be bent there. It is made of a polypropylene plate or similar plastic and the metal sheets are made in particular of aluminum and glued with the exception of the fold on both sides of the entire surface of this plate.

Der Profilrahmen 12 ist rechteckig ausgebildet und damit er vorteilhaft mit der längeren Seite nach oben aufrecht stehen kann, sind bei seiner Schmalseite längliche Nutöffnungen 25, 26 zugeordnet, wie in Fig. 2 ersichtlich ist, und in diese Nutöffnungen 25, 26 ist je ein T-förmiges Fusselement 30 einsteckbar, wie ein solches in Fig. 3 dargestellt ist. Das Fusselement 30 besteht aus zwei Auflagerfüssen 31, 32 und einem Einsteckteil 33, welches einen solchen Querschnitt aufweist, dass es in eine jeweilige Nutöffnung 25, 26 annähernd formschlüssig einsteckbar ist. Zudem ist ein gewinkeltes Federblatt 34 auf der Oberseite des Einsteckteils 33 vorhanden, das ein Herausfallen dieses Fusselementes verhindert.The profile frame 12 is rectangular and so that it can advantageously stand upright with the longer side up, are associated with its narrow side elongated groove openings 25, 26, as in Fig. 2 it can be seen, and in each of these groove openings 25, 26 is a T-shaped foot member 30 can be inserted, as such in Fig. 3 is shown. The foot element 30 consists of two support feet 31, 32 and a male part 33, which has a cross-section such that it can be inserted into a respective groove opening 25, 26 in an approximately form-fitting manner. In addition, an angled spring leaf 34 on the top of the male member 33 is present, which prevents falling out of this foot element.

Bei einer Inbetriebnahme der Leuchtbox werden vorzugsweise in der liegenden zusammengeklappten Position des Profilrahmens zuerst diese Fusselemente eingesteckt, sodann kann der Rahmen aufgestellt und erst anschliessend soll die obere Hälfte desselben nach oben aufgeklappt werden. Im Profilrahmen ist ferner bei der einen Trennstelle 12' zudem ein nicht gezeigtes betätigbares Einrastelement vorgesehen, damit die obere Hälfte des Profilrahmens gegen ein Zuklappen gesichert ist.When commissioning the light box, these foot elements are preferably inserted in the horizontal folded position of the profile frame first, then the frame can be placed and only then should the upper half thereof be folded upwards. In addition, in the profile frame, a not-shown actuatable latching element is provided in the one separating point 12 ', so that the upper half of the profile frame is secured against collapse.

Die Erfindung ist mit dem obigen Ausführungsbeispiel ausreichend dargetan. Sie könnte aber noch durch andere Varianten ausgeführt sein. So könnte beispielsweise die Rückwand mit der Schwenkachse für das Zusammenklappen aus einem oder mehreren Scharnieren bestehen.The invention is sufficiently demonstrated with the above embodiment. But you could still be done by other variants. For example, the rear wall with the pivot axis for folding could consist of one or more hinges.

Selbstverständlich könnte die Leuchtbox je nach Grösse auch mehrfach zusammenlegbar sein und statt rechteckig könnte sie auch andersförmig ausgestaltet sein, wie quadratisch. Auch könnten im gleichen Profilrahmen zwei oder mehrere Bilder neben- oder übereinander fixiert sein.Of course, the light box could also be folded several times depending on the size and instead of rectangular it could also be designed differently shaped, such as square. Also, two or more images could be fixed side by side or one above the other in the same profile frame.
