Description

Die vorliegende Erfindung betrifft einen Schaukasten, bestehend aus einem Gehäuse mit mehreren Fächern zur Aufnahme von Werbemitteln, die mit einem teildurchlässigen Spiegel einseitig verschlossen sind, und innerhalb der im übrigen Licht undurchlässigen Fächer jeweils ein periodisch einschaltbarer Beleuchthgskörper angeordnet ist.The present invention relates to a display case consisting of a housing with a plurality of compartments for receiving advertising material, which are closed on one side with a partially transparent mirror, and a periodically switchable lighting body is arranged within the otherwise opaque compartments.

Ein derartiger Schaukasten ist aus der OS-PS 333 627 bekannt. Hierbei soll die durch die Beleuchtungskörper entstehende Wärme durch ein Gebläse abgeleitet werden, wodurch aber ein relativ hoher Wartungsaufwand erforderlich ist und auch ein nicht unerheblicher Stromverbrauch auftritt. Zudem sind die Beleuchtungskörper derart angeordnet, daß einerseits eine Blendung der betrachtenden Person erfolgt und andererseits keine optimale Ausleuchtung des Schaukastens gegeben ist.Such a showcase is known from OS-PS 333 627. Here, the heat generated by the lighting fixtures is to be dissipated by a blower, but this requires a relatively high level of maintenance and also a not inconsiderable power consumption. In addition, the lighting fixtures are arranged in such a way that on the one hand glare to the viewer Person takes place and on the other hand there is no optimal illumination of the showcase.

Der Erfindung liegt die Aufgabe zugrunde, die vorstehenden Nachteile zu vermeiden und einen Schaukasten der eingangs beschriebenen Art derart zu verbessern, daß aufgrund geringer Wärmeentwicklung durch die Beleuchtungskörper eine Zwangskühlung entfallen kann und eine optimale, blendfreie Ausleuchtung erreicht wird.The invention has for its object to avoid the above disadvantages and to improve a display case of the type described in such a way that forced cooling can be omitted due to low heat development by the lighting fixtures and an optimal, glare-free illumination is achieved.

Erfindungsgemäß wird dies dadurch erreicht, daß die Beleuchtungskörper aus mindestens einer Entladungslampe, insbesondere einer Leuchtstofflampe oder Leuchröhre , bestehen, die oberhalb des Spiegels auf der Spiegelseite pro Fach angeordnet und zwischen der Lampe und dem Spiegel jeweils eine Blende vorgesehen ist. Die vorgenommene erfindungsgemäße Leuchtkörperauswahl zeichnet sich dadurch aus, daß nur eine äußerst geringe Wärmeabgabe von den Beleuchtungskörpern erfolgt, so daß es nicht erforderlich ist, die einzelnen Fächer mittels eines Gebläses derart mit Frischluft zu durchströmen, daß eine Zwangskühlung und Entlüftung erreicht wird. Darüber hinaus ist die Leistungsaufnahme der erfindungsgemäßen Leuchtkörper äußerst gering unter gleichzeitiger Erzielung einer optimalen Ausleuchtung. Hierzu ist es insbesondere wesentlich, daß bei Beleuchtung der einzelnen Fächer die Betrachtungsrichtung in etwa mit der Strahlungsrichtung der Lichtstrahlen übereinstimmt, so daß keine Blendung des Betrachters auftritt. Die Blendfreiheit wird noch dadurch unterstützt, daß erfindungsgemäß der Beleuchtungskörper verdeckt in dem einzelnen Fach angeordnet ist.According to the invention this is achieved in that the lighting fixtures consist of at least one discharge lamp, in particular a fluorescent lamp or tube, which is arranged above the mirror on the mirror side per compartment and a diaphragm is provided between the lamp and the mirror. The lamp selection according to the invention is characterized in that only an extremely small amount of heat is given off by the lighting fixtures, so that it is not necessary to flow through the individual compartments by means of a blower with fresh air in such a way that forced cooling and ventilation is achieved. In addition, the power consumption of the luminous bodies according to the invention is extremely low while at the same time achieving optimum illumination. For this purpose, it is particularly important that when the individual compartments are illuminated, the viewing direction approximately coincides with the direction of radiation of the light rays, so that there is no glare to the viewer. The absence of glare is further supported by the fact that, according to the invention, the lighting fixture is concealed in the individual compartment.

Wie sich aus Fig. 1 ergibt, besteht ein erfindungsgemäßer Schaukasten 1 aus einem Gehäuse 2, das im dargestellten Beispiel, siehe Fig. 4, acht Fächer 3 aufweist, in denen Werbemittel zur Schau gestellt werden können. Die Frontseite des Gehäuses 2 ist mit einem teildurchlässigen Spiegel 4 verkleidet. Der teildurchlässige Spiegel ist derart gestaltet, daß von außen eine Spiegelfläche vorhanden ist, und in dem Moment, wo im Innern des Schaukastens 1 Licht erzeugt wird, der Inhalt der Fächer 3 von außen wahrgenommen werden kann. Aus diesem Grunde ist in jedem einzelnen der Fächer 3 ein Beleuchtungskörper 5 angeordnet, so daß jedes Fach für sich unabhängig von dem anderen Fach beleuchtet werden kann. Bei den Beleuchtungskörpern 5 handelt es sich erfindungsgemäß um Entladungslampen, und zwar vorzugsweise um Leuchtstofflampen oder Leuchtröhren. Diese Art der Beleuchtungskörper zeichnet sich durch eine sehr geringe Leistungsaufnahme aus, wodurch erreicht wird, daß auch nur eine ganz geringe Wärmeabgabe von den Beleuchtungskörpern erfolgt, so daß der Innenraum der Fächer sich während der Brenndauer nur äußerst gering erwärmt, so daß keine Zwangskühlung beispielsweise mittels eines Gebläses erforderlich ist. Die Fächer 3 sind im übrigen vollständig gegen den Eintritt von Licht abgedichtet, was auch in bezug auf die Fächer gegeneinander der Fall ist. Eine derartige Abdichtung ist erforderlich, um den erfindungsgemäß angestrebten Effekt bestmöglichst zu erreichen, nämlich daß nur im Beleuchtungsfall mittels des Beleuchtungskörpers 5 von außen Einblick in die Fächer genommen werden kann; im übrigen aber der teildurchlässige Spiegel 4 als Spiegel wirkt. Unterhalb des teildurchlässigen Spiegels 4 ist im Gehäuse 2 ein Gehäusesockel 6 vorgesehen, in dem die für die-Beleuchtungskörper erforderliche Steuereinheit untergebracht ist.As can be seen from FIG. 1, a display case 1 according to the invention consists of a housing 2 which, in the example shown, see FIG. 4, has eight compartments 3 in which Advertising media can be put on display. The front of the housing 2 is covered with a partially transparent mirror 4. The semitransparent mirror is designed in such a way that there is a mirror surface from the outside, and at the moment when light is generated inside the display case 1, the contents of the compartments 3 can be seen from the outside. For this reason, a lighting fixture 5 is arranged in each of the compartments 3, so that each compartment can be illuminated independently of the other compartment. According to the invention, the lighting fixtures 5 are discharge lamps, preferably fluorescent lamps or fluorescent tubes. This type of lighting fixture is characterized by a very low power consumption, which ensures that only a very small amount of heat is emitted by the lighting fixtures, so that the interior of the compartments heats up only extremely slightly during the burning period, so that no forced cooling, for example, occurs a blower is required. The compartments 3 are otherwise completely sealed against the entry of light, which is also the case with respect to the compartments against each other. Such a seal is necessary in order to achieve the effect sought according to the invention in the best possible way, namely that only in the case of lighting by means of the lighting element 5 can an outside view of the compartments be taken; but otherwise the partially transparent mirror 4 acts as a mirror. Below the partially transparent mirror 4, a housing base 6 is provided in the housing 2, in which the for the lighting fixtures required control unit is housed.

Wie sich insbesondere aus Fig. 1 ergibt, sind die Beleuchtungskörper 5 derart in den einzelnen Fächern 3 angeordnet, daß sie sich auf der Seite des teildurchlässigen Spiegels 4 befinden, und zwar jeweils oberhalb der für das Fach zutreffenden Spiegelfläche. Dabei ist zwischen den Beleuchtungskörpern und dem teildurchlässigen Spiegel 4 jeweils eine Blende 7 angeordnet, wodurch der Beleuchtungskörper 5 vollständig abgedeckt wird, so daß eine Blendung der betrachtenden Person vermieden wird. Durch diese erfindungsgemäße Anordnung verläuft die Blickrichtung des Betrachters und die Strahlenrichtung der von den Beleuchtungskörpern abgestrahlten Lichtstrahlen etwa in derselben Richtung, so daß auch hierdurch eine Blendung vermieden wird. Unterhalb jedes Beleuchtungskörpers 5 befindet sich in den Fächern 3 ein Lichtgitter 8, das den oberen Teil des Innenraums der Fächer 3, in den jeweils die Beleuchtungskörper 5 untergebracht sind, von dem übrigen Fachinnenraum abtrennt. Durch die Lichtgitter, die in bekannter Weise ausgestaltet sind, wird einerseits eine diffuse Ausleuchtung des gesamten Innenraums erreicht und andererseits verhindert, daß sich die Beleuchtungskörper an den Innenwänden des Faches 3 spiegeln können. Die einzelnen Fächer 3 sind durch Fachböden 9 gegeneinander abgetrennt, wobei diese Fachböden 9 bündig an der Rückwand 11 und an den beiden Seitenwänden 12, 13 anliegen bzw. an diesen befestigt sind.As can be seen in particular from FIG. 1, the lighting fixtures 5 are arranged in the individual compartments 3 such that they are located on the side of the partially transparent mirror 4, in each case above the mirror surface applicable to the compartment. In this case, a screen 7 is arranged between the lighting fixtures and the partially transparent mirror 4, as a result of which the lighting fixture 5 is completely covered, so that glare to the person viewing is avoided. By means of this arrangement according to the invention, the viewing direction of the viewer and the beam direction of the light beams emitted by the lighting fixtures run approximately in the same direction, so that glare is also avoided in this way. Below each lighting fixture 5 there is a light grid 8 in the compartments 3, which separates the upper part of the interior of the compartments 3, in which the lighting fixtures 5 are housed, from the rest of the compartment interior. The light grids, which are designed in a known manner, on the one hand achieve diffuse illumination of the entire interior and on the other hand prevent the lighting fixtures from being reflected on the inner walls of the compartment 3. The individual compartments 3 are separated from one another by shelves 9, these shelves 9 being flush with or attached to the rear wall 11 and the two side walls 12, 13.

Wie sich insbesondere aus Fig. 3 und Fig. 5 ergibt, sind die einzelnen Fächer 3 einseitig mittels einer Türe 14 verschlossen, wobei es sich um eine Drehtüre handeln kann.As can be seen in particular from FIGS. 3 and 5, the individual compartments 3 are closed on one side by means of a door 14, which can be a revolving door.

Zweckmäßigerweise sind die Drehtüren mit Schlössern versehen, so daß jedes Fach für sich verschließbar ist.The revolving doors are expediently provided with locks so that each compartment can be locked separately.

Der Raum oberhalb der Lichtgitter 8 der Fächer 3 ist derart ausgekleidet, daß eine Abschirmung des Lichteinfalls erreicht wird. Hierzu kann vorzugsweise als Material Moosgummi oder dgl. verwendet werden. Weiterhin wird hierdurch eine Abdichtung im Anscniußbereich des teildurchlässigen Spiegels erreicht.The space above the light grids 8 of the compartments 3 is lined in such a way that a shielding of the incidence of light is achieved. For this purpose, foam rubber or the like can preferably be used as the material. Furthermore, this is a seal in the A nscniußbereich reaches the partially transmitting mirror.

Zur Ableitung der innerhalb der einzelnen Fächer 3 sich entwickelnden Wärme sind in der Rückwand 11 in der Höhe der Beleuchtungskörper 5 oberhalb der Lichtgitter 8 Entlüftungsschlitze 15 vorgesehen. Weiterhin ist es von Vorteil, wenn an den Innenwänden der Fächer 3 Verkleidungselemente/lösbar befestigt sind. Dabei kann eine derartige lösbare Befestigung mittels an sich bekannter Klettverschlüsse/erfolgen, die an den einzelnen Fachseiten befestigt sind. Hierdurch ist es möglich, die Fächer in beliebiger Weise auszugestalten, s. Fig. 5.To dissipate the heat developing within the individual compartments 3, 8 ventilation slots 15 are provided in the rear wall 11 at the height of the lighting fixtures 5 above the light grids. Furthermore, it is advantageous if 3 cladding elements / are detachably fastened to the inner walls of the compartments. Such a releasable fastening can be carried out by means of Velcro fastenings / which are known per se and which are fastened to the individual compartment sides. This makes it possible to design the subjects in any way, see. Fig. 5.

Weiterhin kann es erfindungsgemäß vorteilhaft sein, wenn anstatt eines Beleuchtungskörpers 5, vorzuqsweise zwei Beleuchtungskörper parallel zueinander geschaltet und angeordnet sind. Hierdurch wird eine noch bessere Ausleuchtung des jeweiligen Faches erreicht und darüber hinaus wird auf diese Weise eine gewisse Reserve geschaffen, denn somit erfolgt auch noch eine Ausleuchtung des Fachs, wenn einer der beiden Beleuchtungskörper ausfällt.
*und PolsterungFurthermore, it can be advantageous according to the invention if, instead of one lighting fixture 5, preferably two lighting fixtures are connected and arranged parallel to one another. This results in an even better illumination of the respective compartment and, in addition, a certain reserve is created in this way, because the compartment is thus also illuminated if one of the two lighting fixtures fails.
* and upholstery

Bei der Verwendung von Entladungslampen, insbesondere Leuchtstofflampen oder Leuchtstoffröhren, besteht das Problem darin, daß diese beim Einschalten nicht sofort konstant aufleuchten, sondern zunächst ein gewisses Flackern auftritt. Diese Flackerneigung ist aber in Verbindung mit einem erfindungsgemäßen Schaukasten nicht zu vertreten, da dann der gewünschte Werbeeffekt verhindert wird. Aus diesem Grunde wurden bei den bekannten Schaukästen bisher Glühlampen verwendet. Diese Glühlampen besitzen aber die eingangs beschriebenen Nachteile, die insbesondere mit der hohen Wärmeentwicklung zusammenhängen. Erfindungsgemäß ist nun eine derartige Ansteuerung der verwendeten Entladungslampen, insbesondere Leuchtstofflampen oder Leuchtstoffröhren vorgesehen, daß dieser Flackereffekt nicht auftreten kann.The problem with the use of discharge lamps, in particular fluorescent lamps or fluorescent tubes, is that they do not immediately light up constantly when switched on, but a certain flickering initially occurs. However, this tendency to flicker is not justifiable in connection with a display case according to the invention, since the desired advertising effect is then prevented. For this reason, incandescent lamps have been used in the known display cases. However, these incandescent lamps have the disadvantages described at the outset, which are related in particular to the high heat development. According to the invention, the discharge lamps used, in particular fluorescent lamps or fluorescent tubes, are controlled in such a way that this flickering effect cannot occur.

Wie sich aus Fig. 6 ergibt, liegt die eine Elektrode 17 der Leuchtstofflampe 5 über eine Drosselspule 18 an Phase. Die andere Elektrode 19.ist über einen elektronischen Schalter 21 mit dem Nulleiter verbunden. Bei dem elektronischen Schalter 21 handelt es sich insbesondere um ein sogenanntes Triac, das aus zwei antiparallel geschalteten Thyristoren besteht, der über ein Steuerteil 22 mit einer Gleichspannung von ca. 3 bis 18 V angesteuert wird. Über dieses Steuerteil 22 kann die Leuchtzeit und die Beleuchtungsfolge der einzelnen Fächer 3 geregelt werden. Die Elektroden 17, 19 werden jeweils über einen Elektrodenheizkreis, s. die Leitungen 26, 27 bzw. 28, 29, geheizt, die von dem Betriebsstromkreis des Leuchtkörpers 5 elektrisch unabhängig sind.Dabei wird ein kontinuierlicher Heizstrom erzeugt, der ständig durch die Elektroden 17, 19 schließt, auch wenn der jeweilige Schalter 21 des Leuchtkörpers geöffnet ist, d.h. der Leuchtkörper nicht leuchtet. Dieser Heizstrom beträgt vorzugsweise etwa 2/3 des Betriebsstroms des Leuchtkörpers, d.h. etwa 0,22 bis 0,25 A bei einer Heizspannung von ca. 6 V. Durch diese ständige Heizung der Elektroden wird die Lebensdauer der Leuchtkörper beträchtlich erhöht und die sofortige Leuchtbereitschaft beim Einschalten der Betriebsspannung erreicht. Zweckmäßigerweise sind die einzelnen Beleuchtungskörper derart geschaltet, daß ihre Eingänge gemeinsam am Ausgang der Drosselspule 18 angeschlossen sind, so daß erfindungsgemäß eine Drosselspule 18 für alle Beleuchtungskörper 5 vorhanden ist. An die Ausgänge der einzelnen Beleuchtungskörper ist jeweils ein elektronischer Schalter 21 geschaltet, so daß pro Beleudtungskörper ein derartiger Schalter vorhanden ist. Demnach bezieht sich die Fig. 6 auf die Schaltungsdarstellung einer einzelnen Leuchtstoffröhre. Zwischen dem Eingang oder Ausgang der Drosselspule 18 und dem Eingang dieses einzelnen elektronischen Schalters 21 ist jeweils ein hochohmiger Widerstand 23 geschaltet, der vorzugsweise einen Widerstandswert von 20 bis 25 KJL besitzt. Durch diese Widerstandsbeschaltung wird erreicht, daß die Leuchtstoffröhre 5 stets mit einer derartigen Spannung beaufschlagt wird, die knapp unterhalb der Glimmspannung liegt. Erfindungsgemäß wird demnach erreicht, daß die einzelnen Beleuchtungskörper sich stets im quasi betriebsbereiten Zustand befinden, so daß bei Auftreten der vollen Zündspannung ein flackerfreies sofortiges Aufleuchten ohne Zeitverzögerung erfolgt.As is apparent from Fig. 6, one electrode 17 is the fluorescent lamp 5 through a choke coil 1 to 8 phase. The other electrode 1 9 is connected to the neutral conductor via an electronic switch 2 1 . In the electronic switch 2 1 is in particular a so-called triac, which consists of two antiparallel-connected thyristors, which is driven via a control part 22 with a DC voltage of about 3 to 1 8 V. The lighting time and the lighting sequence of the individual compartments 3 can be regulated via this control part 22. The electrodes 17 , 1 9 are each via an electrode heating circuit, see. the lines 26, 27 and 28, 29, respectively, which are electrically independent of the operating circuit of the luminous element 5. A continuous heating current is generated which closes continuously through the electrodes 17 , 19, even if the respective switch 2 1 of the Luminous body is open, ie the luminous body is not lit. This heating current is preferably approximately 2/3 of the operating current of the filament, ie approximately 0.22 to 0.25 A at a heating voltage of approximately 6 V. This constant heating of the electrodes considerably increases the lifespan of the filament and the immediate readiness to light up Switching on of the operating voltage reached. The individual lighting fixtures are expediently switched in such a way that their inputs are connected together at the output of the choke coil 18, so that, according to the invention, a choke coil 18 is provided for all the lighting fixtures 5. An electronic switch 2 1 is connected to the outputs of the individual lighting fixtures, so that one such switch is provided for each lighting fixture. Accordingly, FIG. 6 relates to the circuit diagram of a single fluorescent tube. Between the input or output of the inductor 18 and the input of this individual electronic switch 2 1 , a high-resistance resistor 23 is connected, which preferably has a resistance value of 20 to 25 KJL. This resistance circuit ensures that the fluorescent tube 5 is always subjected to such a voltage that is just below the glow voltage. According to the invention it is thus achieved that the individual lighting fixtures are always in a quasi-operational state, so that when the full ignition voltage occurs, a flickering-free, immediate lighting up takes place without a time delay.

Auch liegt es im Rahmen der Erfindung, wenn zwei Leuchtkörper pro Fach parallel geschaltet sind. Hierbei sind die einzelnen Heizstromkreise für die Elektroden der parallel geschalteten Leuchtkörper dann galvanisch gegeneinander getrennt.It is also within the scope of the invention if two illuminants per compartment are connected in parallel. In this case, the individual heating circuits for the electrodes of the illuminants connected in parallel are then galvanically isolated from one another.

Die vorliegende Erfindung ist nicht auf die geschilderte Ausführungsform beschränkt, sondern erstreckt sich ebenfalls auf alle im Sinne der Erfindung gleichwirkenden Ausgestaltungen.The present invention is not limited to the described embodiment, but also extends to all configurations having the same effect in the sense of the invention.
