Description

Die vorliegende Erfindung betrifft ein Kältegerät wie etwa einen Kühlschrank oder einen Gefrierschrank, mit einem Korpus und einer an den Korpus angeschlagenen Tür, die einen wärmeisolierten Innenraum begrenzen. Üblicherweise sind derartige Kältegeräte mit einer Innenraumbeleuchtung versehen, die automatisch eingeschaltet wird, wenn die Tür geöffnet wird. Herkömmlicherweise umfasst eine solche Innenraumbeleuchtung einen einzelnen Leuchtkörper, der an einer seitlichen Innenwand des Korpus angebracht ist.The present invention relates to a refrigerator such as a refrigerator or a freezer, with a body and a door hinged to the body, which define a heat-insulated interior. Usually, such refrigerators are provided with an interior lighting, which is automatically turned on when the door is opened. Conventionally, such an interior lighting comprises a single luminous body, which is attached to a lateral inner wall of the body.

Eine solche Innenraumbeleuchtung beleuchtet Gegenstände in ihrer unmittelbaren Umgebung sehr grell und gibt in unerwünschter Weise auch Wärme an diese Gegenstände ab. Gegenstände, die sich in größerer Entfernung vom Leuchtkörper befinden, eventuell auf anderen Fachböden des Innenraums als demjenigen, auf dem der Leuchtkörper angebracht ist, werden demgegenüber nur schlecht beleuchtet. Außerdem ist es mit einer solchen Innenraumbeleuchtung schwierig, Gegenstände im vorderen Bereich des Innenraums befriedigend zu beleuchten, ohne dabei einen Benutzer, der von vorne in den geöffneten Innenraum schaut, zu blenden.Such an interior lighting illuminates objects in their immediate surroundings very brightly and undesirably also gives off heat to these objects. Objects that are located at a greater distance from the luminous element, possibly on other shelves of the interior than that on which the filament is mounted, in contrast, are only poorly lit. In addition, with such an interior lighting, it is difficult to satisfactorily illuminate objects in the front region of the interior without dazzling a user looking into the opened interior from the front.

Aus EP 0 971 186 A2 ist ein Kältegerät bekannt geworden, bei dem an den Innenseiten des Korpus mehrere Leuchtkörper angebracht sind. Diese Leuchtkörper, die unter anderem auf entgegengesetzten Seiten des Innenraums angebracht sein können oder sich über den größeren Teil von dessen Höhe erstrecken können, ermöglichen eine homogene Ausleuchtung des Innenraums. Die Montage des Kältegeräts gestaltet sich jedoch extrem aufwendig, da eine Vielzahl von Durchbrüchen in der Innenwand des Korpus erforderlich ist, um die Beleuchtungskörper zu montieren und elektrisch zu kontaktieren. Außerdem wird auch bei diesem Kältegerät Abwärme der verwendeten Leuchtmittel zwangsläufig an den Innenraum abgegeben.Out EP 0 971 186 A2 is a refrigeration device has become known in which a plurality of luminous bodies are attached to the insides of the body. These luminous bodies, which may be mounted, inter alia, on opposite sides of the interior or may extend over the greater part of its height, allow a homogeneous illumination of the interior. However, the assembly of the refrigerator is extremely expensive, since a large number of openings in the inner wall of the body is required to mount the lighting fixture and to contact electrically. In addition, even in this refrigerator waste heat of the light source used is inevitably discharged to the interior.

Ein Kältegerät nach dem Oberbegriff des Anspruchs 1 ist aus EP04718931 bekannt geworden.A refrigerator according to the preamble of claim 1 is made EP04718931 known.

Aufgabe der vorliegenden Erfindung ist, ein Kältegerät zu schaffen, das eine gleichmäßige Beleuchtung des Innenraums ohne Blendgefahr für den Benutzer mit einfachen Mitteln ermöglicht.Object of the present invention is to provide a refrigeration device that allows a uniform illumination of the interior without dazzling the user with simple means.

Die Aufgabe wird gelöst durch ein Kältegerät mit den Merkmalen des Anspruchs 1. Indem wenigstens ein Leuchtkörper zur Beleuchtung des Innenraums an einer dem Innenraum zugewandten Innenwand der Tür gemäß dem kennzeichnenden Teil des Anspruchs 1 angebracht ist, kann der Abstand zwischen dem Leuchtkörper und von ihm beleuchteten Gegenständen größer gemacht werden, so dass eine gleichmäßig helle Ausleuchtung erreicht werden kann, und eine Abschattung durch nahe an dem Leuchtkörper platzierte Gegenstände ist ausgeschlossen. Außerdem liegt der Leuchtkörper außerhalb des Hauptblickwinkels eines Benutzers, der ins Innere des geöffneten Kältegeräts schaut, so dass eine direkte Blendgefahr kaum besteht.The object is achieved by a refrigeration device with the features of claim 1. By at least one luminous body for illuminating the interior of an interior facing the inner wall of the door according to the characterizing part of claim 1 is mounted, the distance between the luminous body and illuminated by him Be made larger objects, so that a uniformly bright illumination can be achieved, and shading by placed close to the luminaire objects is excluded. In addition, the luminous body is outside the main viewing angle of a user who looks inside the open refrigerator, so that there is hardly a direct risk of glare.

Um die Möglichkeit einer Blendung vollends auszuschließen, ist vorgesehen, dass der Leuchtkörper überwiegend in einen Winkelbereich abstrahlt, dessen Scheitel der Leuchtkörper selbst bildet und der einerseits durch eine Senkrechte auf der Innenseite der Tür und andererseits durch einen vom Leuchtkörper zur angeschlagenen Seite der Tür verlaufenden Abschnitt von deren Innenseite begrenzt ist. Das heißt, wenn die Tür geöffnet ist und rechtwinklig vom Korpus absteht, so ist die Abstrahlung des Leuchtkörpers im wesentlichen in den Innenraum hinein gerichtet; eine Abstrahlung in Richtung eines vor dem geöffneten Kältegerät stehenden Benutzers, die diesen blenden könnte, findet nicht statt.In order to completely rule out the possibility of glare, it is provided that the luminous element radiates predominantly into an angular range whose apex forms the luminous element itself and on the one hand by a vertical on the inside of the door and on the other hand by a section extending from the filament to the worn side of the door is limited by the inside. That is, when the door is open and protrudes at right angles from the body, the radiation of the filament is directed substantially into the interior; radiation in the direction of a user who is standing in front of the opened refrigeration device and who could dazzle this does not take place.

Ein solcher Leuchtkörper ist vorzugsweise mittig bezogen auf die Breitenrichtung der Tür angeordnet. So ist er unabhängig davon, an welcher Seite die Tür angeschlagen ist, stets geeignet platziert.Such a luminous body is preferably arranged centrally with respect to the width direction of the door. So he is regardless of which side of the door is hinged, always placed appropriately.

Wenn der Leuchtkörper außermittig platziert ist, so ist es zweckmäßig, die Tür mit zwei Montageplätzen beiderseits der Mittellinie zu versehen, an denen der Leuchtkörper wahlweise montierbar ist, so dass er, je nachdem, an welcher Seite die Tür angeschlagen ist, stets geeignet platziert werden kann.If the luminous body is placed off-center, then it is expedient to provide the door with two mounting positions on both sides of the center line, where the filament is optional mountable, so that he, depending on which side the door is hinged, are always placed appropriately can.

Vorzugsweise ist in diesem Fall der Leuchtkörper an demjenigen der zwei Montageplätze montiert, der sich auf der der angeschlagenen Seite der Tür zugewandten Seite der Mittellinie befindet. So ist die Gefahr einer Abschattung durch den Benutzer selbst geringer, als wenn der Leuchtkörper an der anschlagfernen Seite der Tür montiert wäre.Preferably, in this case, the luminous element is mounted on that of the two assembly stations, which is located on the side of the center line facing the damaged side of the door. Thus, the risk of shading by the user is even lower than if the luminaire would be mounted on the off-beat side of the door.

Einer bevorzugten Ausgestaltung zufolge ist der Leuchtkörper an der Tür wahlweise in zwei gegeneinander um 180° um eine zur Tür senkrechte Achse gedrehten Orientierungen montierbar. Dies ist insbesondere zweckmäßig, wenn der Leuchtkörper nicht bevorzugt in Richtung besagter Achse, sondern in den Winkelbereich zwischen der Achse und dem vom Leuchtkörper zur angeschlagenen Seite der Tür verlaufenden Abschnitt der Innenseite strahlen soll. Hier ermöglicht die Drehung eine Anpassung der Strahlrichtung an die jeweils gewählte Anschlagseite der Tür, ohne dass Änderungen an der Konfiguration des Leuchtkörpers selbst erforderlich sind. Wenn der Leuchtkörper mittig an der Tür montiert ist, so sollte dessen Montageplatz ausgelegt sein, um eine Befestigung des Leuchtkörpers in beiden Orientierungen zu ermöglichen; bei zwei außermittigen Montageplätzen kann es genügen, wenn jeder nur die Montage in einer Orientierung erlaubt.According to a preferred embodiment, the luminous element on the door can optionally be mounted in two orientations rotated by 180 ° about an axis perpendicular to the door. This is particularly expedient if the luminous element is not intended to radiate in the direction of said axis, but rather in the angular region between the axis and the section of the inner side extending from the luminous element to the worn side of the door. Here, the rotation allows an adjustment of the beam direction to the respective selected stop side of the door, without any changes to the configuration of the filament itself are required. If the filament is mounted centrally on the door, then its mounting location should be designed to allow attachment of the filament in both orientations; in the case of two eccentric assembly stations, it may be sufficient if everyone only allows assembly in one orientation.

Um eine blendfreie Ausrichtung der Lichtabstrahlung zu gewährleisten, ist vorzugsweise an dem Leuchtkörper ein verstellbares strahlformendes Element angebracht. Bei diesem Element kann es sich insbesondere um einen Reflektor oder um eine Blende handeln. Auch ein lichtbrechendes Element kommt in Betracht.In order to ensure a glare-free alignment of the light emission, an adjustable beam-shaping element is preferably attached to the luminous element. This element may in particular be a reflector or a diaphragm. A refractive element is also considered.

Wenn der Innenraum des Kältegeräts in eine Mehrzahl von Fächern unterteilt ist, sollte sich, um eine gleichmäßige Ausleuchtung zu erreichen, in Höhe jedes Fachs wenigstens ein Leuchtkörper befinden. Diese Anforderung kann erfüllt werden durch mehrere Leuchtkörper, die jeweils in unterschiedlichen Höhen an der Tür angebracht sind; bevorzugt ist ein einzelner Leuchtkörper, der sich über die Höhe mehrerer Fächer erstreckt.If the interior of the refrigeration device is subdivided into a plurality of compartments, at least one illuminant should be located at the level of each compartment in order to achieve uniform illumination. This requirement can be met by a plurality of luminous bodies, which are each mounted at different heights on the door; preferred is a single luminous body which extends over the height of several compartments.

Fig. 1 zeigt in perspektivischer Ansicht einen Kühlschrank 10 als Beispiel für ein erfindungsgemäßes Kältegerät. An einen Korpus 11 des Kühlschranks 10 ist eine Tür 12 schwenkbar angeschlagen. Korpus 11 und Tür 12 begrenzen einen Innenraum 13, der durch Fachböden 16 in eine Mehrzahl von Fächern 17 unterteilt ist. Die Tür 12 hat eine Außenwand 14 aus Blech und eine aus Kunststoffmaterial tiefgezogene Innenwand 15, die an den Rändern miteinander verbunden sind und einen mit isolierendem Schaumstoff ausgefüllten Hohlraum begrenzen. Die Innenwand 15 hat eine im wesentlichen ebene Innenseite 18, die von einer umlaufenden Rippe 19 eingerahmt ist, welche bei geschlossener Tür leicht in den Innenraum 13 vorsteht. Ein Leuchtkörper 20, von dem in der Figur nur ein äußerer Schirm zu erkennen ist, erstreckt sich mittig auf der Innenseite 18 über deren gesamte Höhe. Fig. 1 shows a perspective view of a refrigerator 10 as an example of a refrigerator according to the invention. To a body 11 of the refrigerator 10, a door 12 is hinged. Carcass 11 and door 12 define an interior space 13 which is subdivided by shelves 16 into a plurality of compartments 17. The door 12 has an outer wall 14 of sheet metal and a plastic material deep-drawn inner wall 15, which are interconnected at the edges and define a space filled with insulating foam cavity. The inner wall 15 has a substantially planar inner side 18, which is framed by a circumferential rib 19 which protrudes slightly into the inner space 13 when the door is closed. A luminous element 20, of which only an outer screen can be seen in the figure, extends centrally on the inside 18 over its entire height.

Ein erstes Beispiel für einen möglichen inneren Aufbau des Leuchtkörpers 20 ist in Fig. 2 gezeigt. Die Innenseite 18 weist eine zylindersegmentförmige Vertiefung 21 auf, in der ein Leuchtmittel 22, hier eine Leuchtröhre, gehalten ist. Die Leuchtröhre ist jeweils an ihren Längsenden durch Tragarme 23 mit der Innenwand 15 verbunden, durch die auch eine elektrische Versorgungsleitung 24 für den Leuchtkörper 20 verläuft. Von den erforderlichen zwei Adern der Versorgungsleitung 24 kann jeweils eine in Höhe jedes Tragarms 23 in den Hohlraum 25 der Tür 12 und von dort über das Türscharnier in den Korpus 11 geführt sein. Alternativ kann auch eine Ader der Versorgungsleitung innerhalb der Vertiefung 21 von einem Tragarm 23 zum anderen geführt sein, so dass beide Adern durch einen einzigen Durchbruch der Innenwand 15 an einem der Tragarme 23 verlaufen.A first example of a possible internal structure of the luminous element 20 is shown in FIG Fig. 2 shown. The inner side 18 has a cylinder-segment-shaped recess 21, in which a light source 22, here a light tube, is held. The arc tube is connected in each case at its longitudinal ends by support arms 23 with the inner wall 15 through which an electrical supply line 24 extends for the luminous element 20. Of the required two wires of the supply line 24 can each be guided in the amount of each support arm 23 in the cavity 25 of the door 12 and from there via the door hinge in the body 11. Alternatively, a core of the supply line within the recess 21 may be guided from one support arm 23 to the other, so that both wires extend through a single opening of the inner wall 15 on one of the support arms 23.

Anstelle einer einzigen Leuchtröhre könnten selbstverständlich auch mehrere über die Höhe des Leuchtkörpers 20 verteilte Leuchtmittel verwendet werden. Insbesondere kann anstelle der Röhre ein stabförmiger Träger vorgesehen werden, an dem diese mehrere Leuchtmittel, z.B. Halogenbirnen oder Leuchtdioden, montiert sind, und der über ein Paar von Anschlussklemmen zum Anschließen an die Versorgungsleitung verfügt, mit denen diese mehreren Leuchtmittel parallel oder in Reihe verbunden sind.Instead of a single arc tube could of course also be used over the height of the filament 20 distributed bulbs. In particular, instead of the tube, a rod-shaped support may be provided on which these are mounted a plurality of light sources, for example halogen bulbs or light-emitting diodes, and which has a pair of connection terminals for connection to the supply line to which these multiple light sources are connected in parallel or in series ,

Die Vertiefung 21 ist von einem halbzylinderförmigen Schirm 26, vorzugsweise aus einem durchsichtigen oder durchscheinenden Kunststoff, überdeckt. An der Außenseite des Schirms 26 ist eine sich über dessen gesamte Höhe erstreckende leistenförmige Blende 27 angeordnet, die entlang der Oberfläche des Schirms 26 zwischen zwei einander spiegelbildlich gegenüberliegenden Stellungen verschiebbar ist. In der als durchgezogener Umriss dargestellten Stelle der Blende 27 konzentriert die Blende 27 die Abstrahlung auf einen Winkelbereich zwischen der auf der Tür in Höhe des Leuchtmittels 22 senkrecht stehenden Linie 30 und dem rechts davon liegenden Teil der Türinnenseite 18. Diese Stellung ist für eine rechtsseitig angeschlagene Tür sinnvoll, um eine Blendung eines links von der Tür stehenden Benutzers zu vermeiden. Wenn die Tür linksseitig angeschlagen sein soll, genügt es zum Anpassen der Lichtabstrahlung, die Blende 27 auf die gegenüberliegende Seite des Schirms 26 in die als gestrichelter Umriss dargestellte Stellung zu verschieben.The recess 21 is covered by a half-cylindrical screen 26, preferably made of a transparent or translucent plastic. On the outside of the screen 26 is a extending over its entire height strip-shaped aperture 27 is arranged, which is displaceable along the surface of the screen 26 between two mutually mirror-inverted positions. In the position of the aperture 27, shown as a solid outline, the aperture 27 concentrates the radiation on an angular range between the line 30 perpendicular to the door at the level of the illuminant 22 and the part of the inside of the door 18 lying to the right. This position is for a right-side hinged one Door useful to avoid dazzling a user standing on the left of the door. If the door should be struck on the left side, it is sufficient to adjust the light emission to move the aperture 27 on the opposite side of the screen 26 in the position shown as a dashed outline.

Der in Fig. 3 im Schnitt dargestellte Leuchtkörper 20 unterscheidet sich von dem der Fig. 2 dadurch, dass keine Blende 27 vorhanden ist, und dass der Schirm 26 als eine Abfolge von prismenförmigen Segmenten aufgebaut ist. Die Segmente sind so angeordnet, dass sie einen von dem Leuchtmittel 22 ausgehenden Lichtstrahl im Uhrzeigersinn ablenken, wie in der Figur an einem Lichtstrahl 28 exemplarisch gezeigt. Auch dies ist wirksam, um die Blendung eines links von der als rechtsseitig angeschlagen angenommenen Tür stehenden Benutzers zu verhindern oder zumindest zu verringern.The in Fig. 3 shown in section filament 20 differs from that of Fig. 2 in that there is no shutter 27, and that the screen 26 is constructed as a series of prism-shaped segments. The segments are arranged so that they deflect a light beam emanating from the light source 22 in a clockwise direction, as shown by way of example on a light beam 28 in the figure. This too is effective to prevent or at least reduce the glare of a user who is standing to the left of the user's right-hinged door.

Um die Abstrahlung dieses Leuchtkörpers 20 an einen Anschlagwechsel der Tür anzupassen, genügt es, den Schirm 26 abzumontieren und um 180° gedreht erneut zu montieren, so dass eine Ablenkung der Strahlen im Gegenuhrzeigersinn resultiert.In order to adapt the radiation of this luminous element 20 to an abutment change of the door, it is sufficient to dismantle the screen 26 and re-assemble rotated by 180 ° so that a deflection of the beams results in a counterclockwise direction.

Bei der Ausgestaltung der Fig. 4 ist die Lichtverteilung im wesentlichen durch einen zwischen dem Leuchtmittel 22 und der Innenwand 15 in der Vertiefung 21 angebrachten Reflektor 29 bestimmt. Der Reflektor, der z.B. einen parabel- oder ellipsenförmigen Querschnitt haben kann, ist asymmetrisch angeordnet, um eine Lichtabstrahlung überwiegend in den Bereich zwischen der zur Tür senkrechten Linie 30 und dem anschlagseitigen Teil der Innenseite 18 zu erreichen. Der Reflektor 20 ist am Schirm 26 verankert, so dass der gesamte Leuchtkörper 20, bestehend aus Schirm 26, Leuchtmittel 22 und Reflektor 29, als Einheit von der Tür getrennt und um 180° um die Linie 30 gedreht wieder montiert werden kann, um die bevorzugte Abstrahlrichtung zu ändern, wenn die Tür linksseitig angeschlagen werden soll.In the embodiment of Fig. 4 the light distribution is determined essentially by a reflector 29 mounted between the light source 22 and the inner wall 15 in the recess 21. The reflector, which may for example have a parabolic or elliptical cross-section, is arranged asymmetrically in order to achieve a light emission predominantly in the region between the line 30 perpendicular to the door and the stop-side part of the inner side 18. The reflector 20 is anchored to the screen 26, so that the entire luminous body 20, consisting of screen 26, illuminant 22 and reflector 29, as a unit separated from the door and rotated by 180 ° about the line 30 can be re-mounted to change the preferred direction of radiation, if the door should be struck on the left side.

Bei der Ausgestaltung der Fig. 5 sind das Leuchtmittel 22 und ein Reflektor 31 von einem zylindrischen Schirm 26 rings umschlossen. Der vollständige Leuchtkörper 20 mit Schirm, Reflektor und Leuchtmittel ist an seinen Längsenden drehbar an der Innenseite 18 der Tür gehalten und kann, je nachdem, an welcher Seite die Tür 12 angeschlagen ist, von Hand gedreht werden, um die Abstrahlrichtung anzupassen.In the embodiment of Fig. 5 the lighting means 22 and a reflector 31 are surrounded by a cylindrical screen 26. The complete lamp 20 with screen, reflector and lamp is rotatably supported at its longitudinal ends on the inside 18 of the door and, depending on which side of the door 12 is struck, are rotated by hand to adjust the direction of radiation.

Eine weitere Ausgestaltung des erfindungsgemäßen Kühlschranks ist in Fig. 6 als perspektivische Ansicht dargestellt. Der Leuchtkörper 20 ist hier getrennt von der Tür 12 abgebildet. An der Innenseite 18 der Tür 12 gibt es zwei Montageplätze 32, 33, die vorbereitet sind, um den Leuchtkörper 20 aufzunehmen. Die Montageplätze 32, 33 können z.B. als eine an die Gestalt des Leuchtkörpers 20 angepasste Vertiefung, in der dieser verrastbar oder anderweitig befestigbar ist, durch andere Befestigungsmittel oder durch eine aufgezeichnete oder aufgeklebte Markierung definiert sein. An jedem Montageplatz 32, 33 sind elektrische Kontaktmittel, hier in Form eines Buchsenpaars, für die Stromversorgung des Leuchtkörpers 20 vorgesehen. Die Buchsen 34 befinden sich an den zwei Montageplätzen 32, 33 in unterschiedlichen Höhen, so dass der Leuchtkörper an den zwei Montageplätzen jeweils in um 180° um die Oberflächennormale der Tür gedreht montierbar ist. Auch bei dieser Ausgestaltung ist der Leuchtkörper 20 so konstruiert, dass er bevorzugt schräg zu der Oberflächennormalen 30 abstrahlt. Der Leuchtkörper 20 sollte stets an demjenigen Montageplatz 32 oder 33 montiert werden, der näher an der angeschlagenen Kante der Tür 12 liegt, im hier dargestellten Fall also am Montageplatz 32. Wie die mit Bezug auf die Fig. 2 bis 5 beschriebenen Leuchtkörper ist auch hier der Leuchtkörper 20 so konstruiert, dass er schräg zur Oberflächennormalen 30 abstrahlt, und zwar so, dass er, wenn er am Montageplatz 32 montiert ist, bei geöffneter Tür 12 bevorzugt in den Innenraum 13 hineinstrahlt.A further embodiment of the refrigerator according to the invention is in Fig. 6 shown as a perspective view. The luminous element 20 is shown here separated from the door 12. On the inner side 18 of the door 12, there are two mounting places 32, 33 which are prepared to receive the luminous element 20. The mounting locations 32, 33 can be defined, for example, as a recess adapted to the shape of the luminous element 20 in which it can be latched or otherwise fastened, by other fastening means or by a recorded or affixed marking. At each mounting place 32, 33 are electrical contact means, here in the form of a pair of sockets, provided for the power supply of the filament 20. The sockets 34 are located at the two mounting locations 32, 33 at different heights, so that the luminous body can be mounted rotated at 180 ° about the surface normal of the door at the two mounting locations. Also in this embodiment, the luminous body 20 is designed so that it preferably radiates obliquely to the surface normal 30. The luminous element 20 should always be mounted on that mounting place 32 or 33, which is closer to the hinged edge of the door 12, in the case shown here, therefore, at the mounting location 32. As with reference to the Fig. 2 to 5 described luminaire 20 is here also the luminous body 20 constructed so that it radiates obliquely to the surface normal 30, in such a way that when it is mounted on the mounting station 32, it preferably radiates into the interior 13 when the door 12 is open.

Wenn der Anschlag der Tür 12 auf die linke Seite des Korpus 11 verlegt werden soll, so ist auch der Leuchtkörper 20 auf den Montageplatz 33 zu versetzen. Durch die dabei aufgrund der Platzierung der Buchsen 24 erforderliche Drehung des Leuchtkörpers 20 ist gewährleistet, dass er auch in dieser Stellung bei geöffneter Tür in den Innenraum 13 strahlt, ohne einen Benutzer zu blenden.If the stop of the door 12 is to be moved to the left side of the body 11, then the filament 20 is to be placed on the mounting position 33. By doing due to the placement of the sockets 24 required rotation of the filament 20 is ensured that it radiates in this position with the door open in the interior 13, without dazzling a user.

Anstelle eines einzelnen Leuchtkörpers, der sich über die gesamte Höhe der Tür 12 oder zumindest einen großen Teil davon erstreckt, können selbstverständlich auch mehrere, über die Höhe der Tür verteilte Leuchtkörper in analoger Weise wie oben beschrieben vorgesehen werden.Instead of a single filament extending over the entire height of the door 12 or at least a large part thereof, of course, several, distributed over the height of the door luminous body can be provided in an analogous manner as described above.
