Description

Werbevitrine advertising showcase
Die Erfindung betrifft eine Werbevitrine mit einem rahmen¬ artigen Gehäuse, zumindest einer auf einem lichtdurchlässi¬ gen Träger ausgebildeten Werbefläche und zumindest einer Lichtquelle, die im Inneren des Gehäuses angeordnet ist und mittels der die Werbefläche auf ihrer Rückseite beleuchtbar ist, wobei im Inneren des Gehäuses im Wesentlichen leisten- förmige Reflektoren angeordnet sind, mit denen das von der Lichtquelle ausgehende Licht auf die Rückseite der Werbe- fläche richtbar ist.The invention relates to a display case with a frame-like housing, at least one formed on a lichtdurchlässi¬ gene carrier advertising space and at least one light source which is arranged in the interior of the housing and by means of the advertising space on its back is illuminated, wherein in the interior of the housing essentially strip-shaped reflectors are arranged, with which the light emanating from the light source can be directed onto the rear side of the advertising area.
Eine derartige Werbevitrine findet insbesondere auf öffent¬ lichen Strassen und Plätzen Verwendung und ermöglicht es, auf einer oder mehreren Werbeflächen ein Werbeplakat oder ein sonstiges bildliches Werbeelement in auswechselbarer Weise anzubringen. Um auch bei Dunkelheit die Aufmerksam¬ keit von Personen zu erregen, ist eine Werbevitrine der ge¬ nannten Art üblicherweise beleuchtet, indem die Werbefläche hinterleuchtet ist, d.h. im Inneren des Gehäuses sind meh- rere Lichtquellen angeordnet, mit denen die Werbeflächen und somit das darauf befindliche Werbeplakat von der Rück¬ seite angestrahlt werden kann.Such a display case is used in particular on public streets and squares and makes it possible to affix an advertising poster or other pictorial advertising element in an exchangeable manner on one or more advertising surfaces. In order to attract the attention of persons even in the dark, an advertising display case of the type mentioned is usually illuminated by the backlit advertising area, i. Several light sources are arranged in the interior of the housing with which the advertising surfaces and thus the advertising poster located thereon can be illuminated from the rear side.
Aus ästhetischen Gründen ist es erwünscht, die Werbefläche möglichst gleichmäßig und möglichst hell zu beleuchten. Aus diesem Grunde ist es bekannt, mehrere Lichtquellen in der Werbevitrine zu verwenden. Da bei Verwendung einer Vielzahl von herkömmlichen Glühlampen Probleme bezüglich einer über¬ mäßigen Wärmeentwicklung auftreten können und da der licht-For aesthetic reasons, it is desirable to illuminate the advertising space as evenly as possible and as bright as possible. For this reason, it is known to use several light sources in the advertising display case. Since, with the use of a large number of conventional incandescent lamps, problems with excessive heat generation can occur and since the light
Vt000002 technische Wirkungsgrad derartiger Glühlampen relativ ge¬ ring ist, werden in der Regel mehrere Leuchtstoffröhren verwendet, die parallel zueinander auf Abstand angeordnet werden.Vt000002 technical efficiency of such incandescent lamps is relatively ge ring, a plurality of fluorescent tubes are generally used, which are arranged parallel to each other at a distance.
Aus der DE-B-195 28 925 und der GB-A-2 404 485 ist es be¬ kannt, die Leuchtstoffröhren im Inneren der Rahmenteile des Gehäuses anzuordnen, so dass sie für einen außenstehenden Betrachter der Werbevitrine nicht sichtbar sind. Um das von den Leuchtstoffröhren ausgehende Licht auf die Rückseite des Werbeplakäts zu richten, sind im Inneren des Gehäuses mehrere Reflektoren vorgesehen. Es ist jedoch relativ schwierig, insbesondere den mittleren Bereich des Werbepla¬ kates mit den seitlichen Leuchtstoffröhren gleichmäßig und ausreichend auszuleuchten.From DE-B-195 28 925 and GB-A-2 404 485 it is be¬ known to arrange the fluorescent tubes inside the frame parts of the housing, so that they are not visible to an outside viewer of the display case. To direct the light emanating from the fluorescent tubes to the back of the advertising billboard, several reflectors are provided inside the housing. However, it is relatively difficult to evenly and sufficiently illuminate the central area of the advertising board with the lateral fluorescent tubes.
Statt die Leuchtstoffröhren in den seitlichen Rahmenteilen des Gehäuses zu verstecken, ist es auch bekannt, die Licht¬ quelle in der Mitte des Gehäuses anzuordnen, wie es bei- spielsweise in der DE-A-30 33 462 gezeigt ist. Um eine übermäßige Beleuchtung der Mitte des Werbeplakates zu ver¬ meiden, muss die Lichtquelle mit Abdeckungen versehen wer¬ den, die als Hilfsoptik wirken. Diese Hilfsoptik muss exakt montiert und ausgerichtet werden, wodurch die Montage auf- wendig ist.Instead of hiding the fluorescent tubes in the lateral frame parts of the housing, it is also known to arrange the light source in the middle of the housing, as shown for example in DE-A-30 33 462. In order to avoid excessive illumination of the center of the advertising poster, the light source must be provided with covers which act as auxiliary optics. This auxiliary optics must be mounted and aligned exactly, which makes assembly a lot of work.
Wenn dem Träger bzw. der Werbefläche ein Diffusor, z.B. ei¬ ne Streuscheibe, zugeordnet wird, lassen sich die auf der Werbefläche auftretenden Helligkeitsunterschiede zwar etwas verringern, jedoch verbleiben insbesondere am Rand der Wer¬ befläche weiterhin schwach ausgeleuchtete Bereiche.If the carrier or the advertising surface is a diffuser, e.g. Although a diffusing screen is assigned, the differences in brightness occurring on the advertising surface can indeed be reduced somewhat, but in particular weakly illuminated areas remain on the edge of the advertising surface.
Der Erfindung liegt die Aufgabe zugrunde, eine Werbevitrine der genannten Art zu beschaffen, bei der in einfacher und kostengünstiger Weise eine gleichmäßig ausgeleuchtete Wer¬ befläche erreicht werden kann.The invention has for its object to procure a display case of the type mentioned, in the simple and cost-effective way, a uniformly illuminated wer¬ can be achieved befläche.
Diese Aufgabe wird bei einer Werbefläche der genannten Art mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Dabei ist vorgesehen, dass die im Inneren des Gehäuses an¬ geordneten Reflektoren, von denen zumindest einige im We¬ sentlichen leistenförmig ausgebildet sind, einen umlaufen¬ den, vorzugsweise geschlossenen Rahmen bilden, der zumin- dest ein Rahmenfeld begrenzt, wobei die Lichtquelle oder die Lichtquellen im Inneren des Rahmenfeldes angeordnet sind. Der Rahmen ist im Wesentlichen eben ausgebildet und liegt in der Ebene des rahmenartigen Gehäuses. Dabei kann der aus den Reflektoren gebildete Rahmen in seinen Abmes- sungen so an die Abmessungen des Gehäuses ausgebildet sein, dass er auf oder nahe der Innenwandung des Gehäuses ange¬ ordnet ist. Die den Rahmen bildenden Reflektoren besitzen auf ihrer zur Mitte des Rahmenfeldes weisenden Seite konve¬ xe Reflektorflächen. Auf diese Weise ist gewährleistet, dass das an den Reflektoren reflektierte Licht vorzugsweise die Randbereiche der Werbefläche beleuchtet, wodurch ver¬ mieden ist, dass sich in diesen Randbereiche abgedunkelte Zonen bilden.This object is achieved in an advertising space of the type mentioned with the characterizing features of claim 1. In this case, it is provided that the reflectors arranged inside the housing, of which at least some are substantially strip-shaped, form a circulating, preferably closed frame which delimits at least one frame field, wherein the light source or the light source Light sources are arranged in the interior of the frame field. The frame is substantially planar and lies in the plane of the frame-like housing. In this case, the frame formed from the reflectors may be formed in its dimensions to the dimensions of the housing so that it is arranged on or near the inner wall of the housing ange¬. The reflectors forming the frame have convex reflector surfaces on their side facing the center of the frame field. In this way, it is ensured that the light reflected at the reflectors preferably illuminates the edge regions of the advertising surface, whereby it is avoided that darkened zones form in these edge regions.
Es hat sich gezeigt, dass mittels der Reflektoren die im Inneren des Gehäuses auftretenden Absorptionsverluste we¬ sentlich verringert werden können, so dass mit einer rela¬ tiv geringen Anzahl von Lichtquellen eine gleichmäßige Lichtverteilung auf der Werbefläche bei gleichzeitig rela- tiv geringem Energieverbrauch gewährleistet ist. Mittels der Reflektoren lässt sich das Licht innerhalb der Vitrine in geeigneter Weise auf der Werbefläche verteilen, wobei auch bei der erfindungsgemäßen Werbevitrine dem Träger bzw. der Werbefläche vorzugsweise eine Streuscheibe zugeordnet ist. Die Montage des von den Reflektoren gebildeten Rahmens ist erleichtert, wenn der Rahmen in Weiterbildung der Erfindung als eine vorgefertigte, eigenstabile Baugruppe ausgebildet ist, die lediglich in das Gehäuse der Werbevitrine einge¬ setzt und festgelegt werden muss.It has been found that by means of the reflectors the absorption losses occurring in the interior of the housing can be substantially reduced, so that with a relatively small number of light sources, a uniform light distribution on the advertising surface is guaranteed with relatively low energy consumption. By means of the reflectors, the light can be distributed within the display case in a suitable manner on the advertising surface, wherein also in the case of the advertising display case according to the invention the carrier or the advertising surface is preferably associated with a diffusing screen. The assembly of the frame formed by the reflectors is facilitated if the frame is formed in a further development of the invention as a prefabricated, intrinsically stable assembly, which only sets einge¬ in the housing of the display case and must be set.
Die den Rahmen bildenden leistenförmigen Reflektoren besit¬ zen vorzugsweise zumindest auf ihrer der Mitte des Rahmen- feldes bzw. der Lichtquelle zugewandten Seite einen stetig gekrümmten, konvexen Querschnitt, der im Wesentlichen halb¬ kreisförmig ausgebildet sein kann, wobei die konvexe Re¬ flektorfläche zur Mitte des Rahmenfeldes weist. Alternativ können die leistenförmigen Reflektoren einen Polygon- Querschnitt und insbesondere einen im Wesentlichen drei¬ eckigen Querschnitt besitzen, wobei die Basis der Dreiecks¬ form dem äußeren Gehäuse zugewandt ist und die Spitze der Dreiecksform zur Mitte des Rahmens weist. Auf diese Weise sind schräg zur Mittelebene des Rahmens und somit der Wer- bevitrine verlaufende Reflektorflächen gebildet, die das Licht wirkungsvoll auf die Werbeflächen umlenken.The strip-shaped reflectors forming the frame preferably have a continuously curved, convex cross-section, at least on their side facing the center of the frame field or the light source, which can be substantially semicircular, with the convex reflector surface facing the center of the frame field points. Alternatively, the strip-shaped reflectors may have a polygonal cross section and in particular a substantially triangular cross section, the base of the triangular shape facing the outer housing and the apex of the triangular shape facing the center of the frame. In this way, reflector surfaces running obliquely to the median plane of the frame and thus of the advertising vitrine are formed, which deflect the light effectively onto the advertising surfaces.
Die reflektierenden Oberflächen der leistenförmigen Reflek¬ toren können das Licht entweder gerichtet oder ungerichtet, d.h. diffus reflektieren.The reflective surfaces of the strip-shaped reflectors may direct the light either directionally or non-directionally, i. diffuse reflectively.
Der äußere umlaufende Rahmen ist in Weiterbildung der Er¬ findung durch stabförmige Reflektorstege in mehrere Rahmen¬ felder unterteilt, wobei in jedem Rahmenfeld zumindest eine Lichtquelle angeordnet ist. Die Rahmenfelder sind vorzugs¬ weise gleich groß und nehmen jeweils eine röhrenförmige Lichtquelle, insbesondere eine Leuchtstoffröhre auf, wobei die röhrenförmigen Lichtquellen parallel zueinander verlau¬ fen. Auf diese Weise ist jede Lichtquelle von einem eigenen Teil-Rahmen umgeben, so dass das von der jeweiligen Licht- quelle abgegebene Licht wirkungsvoll reflektiert und in die- gewünschte Richtung umgelenkt werden kann.The outer circumferential frame is subdivided in a further development of Er¬ invention by rod-shaped reflector webs in several Rahmen¬ fields, wherein in each frame field, at least one light source is arranged. The frame fields are preferably the same size and each receive a tubular light source, in particular a fluorescent tube, wherein the tubular light sources run parallel to one another. In this way, each light source is surrounded by its own sub-frame, so that the light from the respective light source the light emitted can be effectively reflected and redirected in the desired direction.
Die stabförmigen Reflektorstege besitzen beispielsweise ei- nen im Wesentlichen rautenförmigen oder rechteckigen Quer¬ schnitt, wobei jeweils eine Ecke der Rauten- bzw. Rechteck¬ form der zugeordneten Lichtquelle zugewandt ist. Alternativ können die stabförmigen Reflektoren einen kreis- oder el- lipsenförmigen, konvexen Querschnitt besitzen. Bei einer ellipsenförmigen Querschnittsform der Reflektorstege sollte diese so ausgerichtet sein, dass die längere Hauptachse der Ellipse im Wesentlichen in der Rahmenebene liegt und zu der zugeordneten Lichtquelle weist.The rod-shaped reflector webs have, for example, a substantially diamond-shaped or rectangular cross-section, with one corner of the diamond or rectangular shape facing the associated light source. Alternatively, the rod-shaped reflectors may have a circular or elliptical, convex cross section. In an elliptical cross-sectional shape of the reflector webs, this should be aligned so that the longer major axis of the ellipse lies substantially in the frame plane and facing the associated light source.
In Weiterbildung der Erfindung kann vorgesehen, dass dieIn a further development of the invention can be provided that the
Lichtquelle bzw. die Leuchtstoffröhre mit Abstand von einer Lichtsteuerhülse umgeben ist. Die Lichtsteuerhülse besitzt über ihren Umfang verteilte Bereiche unterschiedlicher Lichtdurchlässigkeit. Dabei ist die Lichtsteuerhülse so an- geordnet, dass das von der Lichtquelle ausgehende und di¬ rekt zum Träger bzw. zur Werbefläche gerichtete Licht durch die Lichtsteuerhülse stärker gedämpft ist. Dies führt dazu, dass ein Großteil von der Lichtquelle ausgehenden Lichtes zunächst im Wesentlichen in oder nahe der Mittelebene des Rahmens verläuft und dann über die Reflektoren auf den Trä¬ ger bzw. die Werbefläche gerichtet wird. Nur ein Teil des von der Lichtquelle ausgehenden Lichtes wird infolge der Lichtsteuerhülse direkt den Träger bzw. die Werbefläche ge¬ richtet. Auf diese Weise lässt sich eine annähernd einheit- liehe Lichtverteilung auf der Werbefläche erreichen.Light source or the fluorescent tube is surrounded by a distance from a light control sleeve. The light control sleeve has distributed over its circumference areas of different light transmission. In this case, the light control sleeve is arranged in such a way that the light emanating from the light source and direct to the carrier or to the advertising surface is more strongly damped by the light control sleeve. As a result, a large part of the light emitted by the light source initially runs substantially in or near the center plane of the frame and is then directed onto the carrier or the advertising surface via the reflectors. Only part of the light emanating from the light source is directed directly to the carrier or the advertising surface due to the light control sleeve. In this way, an approximately uniform Liehe distribution of light on the advertising space can be achieved.

Gemäß Fig. 1 besitzt eine Werbevitrine 10 ein äußeres rah- menartiges Gehäuse 11, in das ein Reflektorrahmen 12 einge¬ setzt ist, wie er in Fig. 2 dargestellt ist. Der Reflektor¬ rahmen 12 besitzt zwei parallel auf Abstand angeordnete, vertikale, leistenförmige Reflektoren 13 und 14, die an ih¬ rem oberen und ihrem unteren Ende über jeweils einen hori- zontalen leistenförmigen Reflektor 15 bzw. 16 verbunden sind. Die vier leistenförmigen Reflektoren 13, 14, 15 und 16 bilden somit einen geschlossenen ebenen, rechteckigen Rahmen, der ein rechteckiges Rahmenfeld 22 bildet und um¬ gibt. In dem Rahmenfeld 22 sind drei Leuchtstoffröhren 19 angeordnet, die sich jeweils vertikal zwischen den Reflek¬ toren 15 und 16 erstrecken und parallel zueinander in ge¬ genseitigem seitlichem Abstand angeordnet sind. Die Leucht¬ stoffröhren 19 sind in nicht dargestellter Weise an eine Spannungsquelle angeschlossen. Wie Fig. 1 zeigt, besitzen die den äußeren Rahmen bildenden Reflektoren 13, 14, 15 und 16 jeweils einen im Wesentlichen halbkreisförmigen Querschnitt, wobei die geradlinige Basis der Halbkreisform dem äußeren Gehäuse 11 zugewandt ist und eine konvex gekrümmte Reflektorfläche 13a, 14a, 15a, 16a zur Mitte des Rahmens 12 weist.According to FIG. 1, an advertising display case 10 has an outer frame-type housing 11 into which a reflector frame 12 is inserted, as shown in FIG. 2. The Reflektor¬ frame 12 has two parallel spaced, vertical, strip-shaped reflectors 13 and 14, which are connected at ih¬ the upper and its lower end via a respective horizontal strip-shaped reflector 15 and 16 respectively. The four strip-shaped reflectors 13, 14, 15 and 16 thus form a closed, planar, rectangular frame, which forms a rectangular frame field 22 and surrounds. In the frame field 22, three fluorescent tubes 19 are arranged, each of which extends vertically between the reflectors 15 and 16 and are arranged parallel to each other at a mutual lateral distance. The Leucht¬ fabric tubes 19 are connected in a manner not shown to a voltage source. As shown in FIG. 1, the reflectors 13, 14, 15 and 16 forming the outer frame each have a substantially semicircular cross-section, the rectilinear base of the semicircular shape facing the outer housing 11 and a convexly curved reflector surface 13a, 14a, 15a, 16a to the center of the frame 12 has.
Auf beiden Seiten des Rahmens 12 ist in dem Gehäuse 11 je- weils eine lichtdurchlässige Streuscheibe 20 angeordnet, auf deren Außenseite eine Werbefläche 21 zur Anbringung ei¬ nes Werbeplakats etc. gebildet ist.On both sides of the frame 12, a translucent lens 20 is arranged in the housing 11, on the outside of which an advertising surface 21 for attaching a billboard, etc., is formed.
Das von den Leuchtstoffröhren 19 abgegebene Licht trifft teilweise direkt auf die Streuscheiben 20 und durchdringt diese zumindest teilweise. Darüber hinaus fällt das von den Leuchtstoffröhren 19 abgegebene Licht auf die Reflektorflä¬ chen 13a, 14a, 15a und 16a der den äußeren Rahmen bildenden Reflektoren 13, 14, 15 und 16, an denen das Licht umgelenkt und ebenfalls auf die Streuscheiben 20 gerichtet wird.The light emitted by the fluorescent tubes 19 partially hits directly on the lenses 20 and penetrates them at least partially. In addition, the light emitted by the fluorescent tubes 19 falls on the reflector surfaces 13a, 14a, 15a and 16a of the outer frames forming reflectors 13, 14, 15 and 16, at which the light is deflected and also directed to the lenses 20.
Die Figuren 3 und 4 zeigen eine zweite Ausführungsform der Werbevitrine, die ebenfalls die Merkmale der ersten Ausfüh¬ rungsform aufweist. Zusätzlich ist der Reflektorrahmen 12 mittels zweier stabförmiger Reflektorstege 17 und 18, die parallel zu den vertikalen Reflektoren 13 und 14 und auf Abstand zu diesen verlaufen, in drei etwa gleichgroße Rah¬ menfelder 22, 23 und 24 unterteilt. In jedem Rahmenfeld 22, 23 und 24 ist jeweils mittig eine Leuchtstoffröhre 19 ange- ordnet, wobei die Leuchtstoffröhren 19 parallel zueinander verlaufen.Figures 3 and 4 show a second embodiment of the advertising showcase, which also has the features of the first Ausfüh¬ insurance form. In addition, the reflector frame 12 by means of two rod-shaped reflector webs 17 and 18, which extend parallel to the vertical reflectors 13 and 14 and at a distance therefrom, divided into three approximately equal Rah¬ menfelder 22, 23 and 24. In each frame field 22, 23 and 24, a fluorescent tube 19 is arranged centrally in each case, the fluorescent tubes 19 extending parallel to one another.
Die Reflektorstege 17 und 18 besitzen einen leicht ellip- senförmigen Querschnitt, der so ausgerichtet ist, dass je- weils die längere Hauptachse der Ellipsenform zu der be- nachbarten Leuchtstoffröhre 19 weist. Wie dargestellt ist, kann die Ellipsenform in den Endpunkten der längeren Haupt¬ achse eine ünstetigkeitsstelle bzw. einen Knick aufweisen, so dass die Reflektorstege 17, 18 jeweils Seitenkanten be- sitzen, die den zugeordneten Leuchtstoffröhren 19 zugewandt sind. Die freiliegenden konvexen Reflektorflächen 17a und 18a der Reflektorstege 17 und 18 können jeweils spiegelnd oder diffus reflektierend ausgebildet sein.The reflector webs 17 and 18 have a slightly ellipse-shaped cross-section, which is oriented so that the longer major axis of the elliptical shape is in each case aligned with the adjacent fluorescent tube 19 has. As shown, the ellipse shape in the end points of the longer Haupt¬ axis have a ünstetigkeitsstelle or a kink, so that the reflector webs 17, 18 each have side edges, which are facing the associated fluorescent tubes 19. The exposed convex reflector surfaces 17a and 18a of the reflector webs 17 and 18 may each be designed to be reflective or diffuse reflective.
Fig. 5 zeigt eine Weiterbildung der Ausgestaltung gemäßFig. 5 shows a development of the embodiment according to
Fig. 3, jedoch kann diese auch in gleichartiger Weise als Weiterbildung der Ausgestaltung gemäß Fig. 1 verwendet wer¬ den. Um zu verhindern, dass ein übermäßig großer Anteil des von den Leuchtstoffröhren 19 abgegebenen Lichtes direkt auf die Streuscheiben 20 fällt, können die Leuchtstoffröhren 19 mit Abstand jeweils von einer Lichtsteuerhülse 25 umgeben sein, wie es in Fig. 5 beispielhaft dargestellt ist. Die Lichtsteuerhülse 25 zeichnet sich dadurch aus, dass sie ü- ber ihren Umfang verteilte Bereiche B unterschiedlicher Lichtdurchlässigkeit besitzt. Die den Streuscheiben 20 zu¬ gewandten Bereiche B der Lichtsteuerhülse 25 lassen das von der innerhalb der Lichtsteuerhülse 25 angeordneten Leucht¬ stoffröhre abgegebene Licht nur teilweise hindurch und so¬ mit direkt auf die Streuscheiben 20 auftreffen. Der größere Teil des Lichts tritt seitlich, d.h. im Wesentlichen in der Mittelebene des Reflektorrahmens 12 aus der Lichtsteuerhül¬ se 25 auf und trifft dann auf die Reflektorflächen der Re¬ flektoren 13, 14, 15 und 16 bzw. der mittleren Reflektor¬ stege 17 und 18 und gelangt erst nach Reflexion an diesen auf die Streuscheiben 20. Auf diese Weise sind die Leucht¬ stoffröhren 19 von einem Betrachter der Werbevitrine von der Außenseite nicht erkennbar und es lässt sich der Ein¬ druck einer gleichmäßig ausgeleuchteten Werbefläche errei¬ chen. Fig. 3, but this can also be used in a similar manner as a development of the embodiment of FIG. 1 wer¬ the. In order to prevent an excessively large proportion of the light emitted by the fluorescent tubes 19 from falling directly onto the lenses 20, the fluorescent tubes 19 can each be surrounded at a distance by a light control sleeve 25, as shown by way of example in FIG. The light control sleeve 25 is characterized in that it has distributed areas B of different light transmission over its circumference. The areas B of the light control sleeve 25 facing the lenses 20 allow the light emitted by the fluorescent tube inside the light control sleeve 25 to pass through only partially and thus strike the lenses 20 directly. The greater part of the light passes laterally, i. essentially in the center plane of the reflector frame 12 from the light control sleeve 25 and then impinges on the reflector surfaces of the reflectors 13, 14, 15 and 16 or the central reflector webs 17 and 18 and only reaches this after reflection the diffusers 20. In this way, the Leucht¬ tube tubes 19 are not visible from a viewer of the display case from the outside and it can reach the Ein¬ pressure of a uniformly illuminated billboard surfaces.
