Description

Die Erfindung betrifft eine Leuchte.The invention relates to a lamp.

Es sind bereits Leuchtstofflampen bzw. -röhren bekannt, die vielfältig eingesetzt werden. Derartige Röhren sind hinsichtlich ihrer Zusatzeinrichtungen, wie Glimmzünder und Kompensationskondensatoren, recht aufwendig und teuer und müssen im Fall eines Defektes im ganzen ersetzt werden. Darüberhinaus müssen derartige Leuchtstofflampen- bzw. röhren mit Netzspannung bzw. mit Hochspannung betrieben werden, was in vielen Fällen nicht wünschenswert ist. Die Leuchtstofflampen bzw. -röhren bekannter Bauart erzeugen zum Teil recht kaltes, unnatürliches. Licht, was insbesondere zur Beleuchtung,von wertvollen Gegenständen, wie Bildern, sonstigen Kunstgegenstä..nden, Museumsgegenständen und bei der Verwendung im Zusammenhang mit Vitrinen und Schaukästen, unerwünscht ist.Fluorescent lamps or tubes are already known and are used in a variety of ways. Such tubes are quite complex and expensive with regard to their additional devices, such as glow igniters and compensation capacitors, and must be replaced as a whole in the event of a defect. In addition, such fluorescent lamps or tubes have to be operated with mains voltage or with high voltage, which is not desirable in many cases. The fluorescent lamps or tubes of known design sometimes produce quite cold, unnatural ones. Light, which is particularly undesirable for lighting, valuable objects, such as pictures, other art objects, museum objects and when used in connection with showcases and display cases.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Leuchte, insbesondere eine rohrförmige Leuchte zu schaffen, die äusserst einfach und kostengünstig hergestellt werden kann, ein natürliches, warmes Licht ergibt, auch mit einer geringeren Spannung als der Netzspannung betrieben werden kann und hinsichtlich des Auswechselns von dabei verwendeten Lampen sehr wartungsfreundlich ist.The invention is therefore based on the object to provide a luminaire, in particular a tubular luminaire, which can be produced extremely simply and inexpensively, gives a natural, warm light, can also be operated with a voltage lower than the mains voltage and with regard to the replacement of lamps used are very easy to maintain.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass wenigstens zwei Soffittenlampen als Lichtquellen in Reihe hintereinander in einem Leuchtenrohr angeordnet sind.According to the invention, this object is achieved in that at least two festoon lamps are arranged in series as light sources in a lamp tube.

Soffittenlampen werden beispielsweise für die Kraftfahrzeug-Elektrik und für die Signaltechnik mit hoher Lebensdauer in sehr hohen Stückzahlen gefertigt und sind daher äusserst preiswert. Darüberhinaus geben sie ein ansprechendes, natürliches, warmes Licht im Gegensatz zu Leuchtstoffröhren.Festoon lamps are manufactured in very large numbers, for example, for automotive electronics and for signaling technology with a long service life and are therefore extremely inexpensive. In addition, they give an appealing, natural, warm light in contrast to fluorescent tubes.

Gemäss einer bevorzugten Ausführungsform der Erfindung sind an den äusseren Kontaktenden der Soffittenlampenreihe Druckfedern, vorzugsweise Spiralfedern, angebracht, die die Soffittenlampen mit ihren Kontaktenden aneinanderdrücken, so dass dadurch ein guter elektrischer Kontakt geschaffen wird und der Übergangswiderstand möglichst klein gehalten wird. Durch die Druckfedern ist es sehr einfach, im Falle des Durchbrennens einer Soffittenlampe diese auszuwechseln, da sie nur gegen die Federkraft der Druckfeder verschoben und aus dem Leuchtenrohr herausgenommen zu werden braucht. Das Einsetzen der neuen Soffittenlampe ist ebenso einfach.According to a preferred embodiment of the invention, compression springs, preferably spiral springs, are attached to the outer contact ends of the row of tubular lamps, which press the tubular lamps together with their contact ends, so that good electrical contact is created and the contact resistance is kept as low as possible. The compression springs make it very easy to replace a tubular lamp if it burns out, since it only needs to be moved against the spring force of the compression spring and removed from the lamp tube. Inserting the new festoon lamp is just as easy.

Nach einer erfindungsgemässen, alternativen Ausführungsform befindet sich zwischen jeweils aufeinander zu gerichteten Kontaktenden zweier Soffittenlampen eine Zwischendruckfeder, die ebenfalls elektrisch leitend ist und dadurch einen sicheren und elastischen Kontakt zwischen den einzelnen Soffittenlampen gewährleistet. Die Zwischendruckfedern sind jedoch üblicherweise nicht erforderlich, insbesondere dann, wenn das Leuchtenrohr nicht allzu lang ist. In diesem Falle reichen ein oder zwei aussenliegende Druckfedern aus.According to an alternative embodiment according to the invention, an intermediate compression spring is located between the contact ends of two festoon lamps which are directed towards each other, which is also electrically conductive and thereby ensures reliable and elastic contact between the individual festoon lamps. However, the intermediate pressure springs are usually not required, especially if the lamp tube is not too long. In this case, one or two external compression springs are sufficient.

In einigen Fällen, insbesondere bei relativ langen Leuchtenrohren, oder bei etwas gekrümmten Leuchtenrohren, in denen die Soffittenlampen zueinander in einem Winkel kleiner als 1800 liegen, gewährleisten die Zwischendruckfedern einen besseren Kontakt zwischen den einzelnen Soffittenlampen.In some cases, especially in the case of relatively long lamp tubes or in the case of somewhat curved lamp tubes in which the tubular lamps lie at an angle of less than 1800, the intermediate pressure springs ensure better contact between the individual tubular lamps.

Um zu verhindern, dass die Kontaktenden der Soffittenlampen mit dem normalerweise geerdeten Leuchtenrohr in Berührung kommen, sind gemäss einer weiteren bevorzugten Ausführungsform Hülsen aus nicht-leitendem Material, das vorzugsweise bis zu 1200 C hitzebeständig ist und etwa Teflon sein kann, vorgesehen. Diese Hülse umfasst vorzugsweise beide zylindrischen Umfangsflächen der aufeinander zu gerichteten Kontaktenden zweier Soffittenlampen und gegebenenfalls die Zwischendruckfeder. Die Hülse dient auch als Abstandshalter, um zu verhindern, dass das Glas der Soffittenlampen beispielsweise bei einer Erschütterung mit dem Leuchtenrohr in Berührung kommt, wodurch durch den an dieser Stelle auftretenden starken Wärmeabfluss gegebenenfalls Spannungen im Glas auftreten können und die Soffittenlampe zerstört wird.In order to prevent the contact ends of the festoon lamps from coming into contact with the normally grounded lamp tube, sleeves made of non-conductive material, which is preferably heat-resistant up to 120 ° C. and can be Teflon, for example, are provided according to a further preferred embodiment. This sleeve preferably comprises both cylindrical peripheral surfaces of the contact ends of two tubular lamps which are directed towards one another and, if appropriate, the intermediate compression spring. The sleeve also serves as a spacer, in order to prevent the glass of the festoon lamps from coming into contact with the lamp tube, for example in the event of a vibration, as a result of which, due to the strong heat flow occurring at this point, stresses can possibly occur in the glass and the festoon lamp is destroyed.

Das Leuchtenrohr weist einen je nach den Gegebenheiten gewählten breiteren oder schmaleren Schlitz über eine bestimmte Länge des Leuchtenrohrs auf, aus dem Licht austreten kann. Vorzugsweise ist das Leuchtenrohr in dem Leuchtenkörper bzw. Leuchtenrohrhaltern drehbar - der Erdung halber jedoch elektrisch leitend - verbunden. Durch Drehen des Leuchtenrohrs ist es daher möglich, einen bestimmten Gegenstand, beispielsweise ein Gemälde, optimal und individuell anzuleuchten.The lamp tube has a wider or narrower slot, depending on the circumstances, over a certain length of the lamp tube, from which light can emerge. The luminaire tube is preferably rotatable in the luminaire body or luminaire tube holder, but is electrically conductive for grounding purposes. By turning the lamp tube, it is therefore possible to optimally and individually illuminate a certain object, for example a painting.

Die erfindungsgemässe Leuchte ist insbesondere zur Beleuchtung von Gemälden, Bildern, Schaukästen, Vitrinen, Anschlagtafeln und von Werbemitteln, wie Plakaten usw., besonders gut geeignet. Denn im Gegensatz zu Spottleuchten, die in diesen Fällen vornehmlich verwendet werden, ist mit der erfindungsgemässen Leuchte eine gleichmässigere Ausleuchtung möglich und insbesondere gibt die erfindungsgemesse Leuchte wesentlich weniger Wärme ab, die im Gegensatz zu Spottleuchten auch besser verteilt und nicht punktuell auf einer kleinen Fläche auf einen Gegenstand, wie beispielsweise ein Gemälde, abgestrahlt wird. Insbesondere Bilder, Gemälde mit einem Firnisüberzug und sonstige, wärme- und hitzeempfindliche Gegenstände sind daher bei Ausleuchtung mit der erfindungsgemässen Leuchte nicht gefährdet.The lamp according to the invention is particularly well suited in particular for illuminating paintings, pictures, display cases, showcases, notice boards and advertising materials, such as posters, etc. Because in contrast to mock-up lights, which are mainly used in these cases, more uniform illumination is possible with the luminaire according to the invention and in particular the luminaire according to the invention emits significantly less heat, which, in contrast to mock-up lights, also distributes better and does not give up selectively on a small area an object, such as a painting, is emitted. In particular, pictures, paintings with a varnish coating and other heat and heat sensitive objects are therefore not at risk when illuminated with the lamp according to the invention.

Gemäss einer weiteren Ausgestaltung der vorliegenden Erfindung weisen die Leuchtkörper mehrere Leuchtenrohrhalter auf, in denen mehrere Leuchtenrohre jeweils parallel zueinander angeordnet sind. Dadurch lassen sich auf einfache Weise und sehr kostengünstig die unterschiedlichsten Leuchten, wie beispielsweise flächenhafte Leuchten, Leuchten mit senkrecht stehenden, parallel angeordneten Leuchtenrohren usw., schaffen.According to a further embodiment of the present invention, the luminous bodies have a plurality of lamp tube holders, in which a plurality of lamp tubes are each arranged parallel to one another. This allows the most varied of lights, such as, in a simple and very cost-effective manner For example, create areal lights, lights with vertical, parallel arranged lamp tubes, etc.

Die Erfindung wird nachstehend anhand einer Zeichnung beispielsweise näher erläutert.The invention is explained in more detail below with reference to a drawing, for example.

In dem einen Leuchtenkörper bzw. Leuchtenrohrhalter 6 befindet sich eine Druckfeder 5, die aus leitendem Material besteht und an einer leitenden, gegenüber dem sonstigen Leuchtenkörper isolierten Platte anliegt. Diese Platte ist mit einer Anschlussleitung 12 verbunden. In der Nähe der Enden der Leuchtenrohrhalter 6 sind Nieten 13 angebracht, wobei der innenliegende Nietenkopf in einer entsprechenden Ausnehmung 14 eines Leuchtenrohrs 3 liegt. Das Leuchtenrohr ist gegenüber dem Leuchtenkörper daher gegen eine axiale Verschiebung geschützt; dagegen lässt sich das Leuchtenrohr 3 auf Grund der Ausnehmung bzw. Nut 14 auf dem Aussenumfang des Leuchtenrohrs 3 um seine Längsachse drehen. Zu Isolationszwecken ist die Druckfeder 5 von einer aus elektrisch nicht-leitendem Material bestehenden Hülse 15 umschlossen, durch die ein äusseres Kontaktende 4 der in der Zeichnung am weitesten rechts liegenden Soffittenlampe 2 hindurchreicht, Diese Soffittenlampe 3 bzw. deren äusseres Kontaktende 4 steht mit der Druckfeder 5 in Berührung, die einerseits eine elektrische Leitung zwischen dem Anschlusskabel 12 und dem Kontaktende bildet und andererseits die Soffittenlampe zu einer oder mehreren weiteren Soffittenlampen im Leuchtenrohr hindrückt, so dass zwischen.den Kontaktenden 4 der jeweiligen Soffittenlampen ein guter elektrischer Kontakt gewährleistet ist.In the one lamp body or lamp tube holder 6 there is a compression spring 5, which consists of conductive material and rests against a conductive plate that is insulated from the other lamp body. This plate is connected to a connecting line 12. Rivets 13 are attached near the ends of the lamp tube holder 6, the internal rivet head being located in a corresponding recess 14 in a lamp tube 3. The lamp tube is therefore protected against axial displacement relative to the lamp body; on the other hand, the lamp tube 3 can be rotated about its longitudinal axis due to the recess or groove 14 on the outer circumference of the lamp tube 3. For insulation purposes, the compression spring 5 is enclosed by a sleeve 15 made of electrically non-conductive material, through which an outer contact end 4 of the right-most tubular lamp 2 in the drawing extends. This tubular lamp 3 or its outer contact end 4 stands with the compression spring 5 in contact, which on the one hand forms an electrical line between the connecting cable 12 and the contact end and on the other hand presses the tubular lamp to one or more further tubular lamps in the lamp tube, so that good electrical contact is ensured between the contact ends 4 of the respective tubular lamps.

Um zu verhindern, dass die Kontaktenden 4 der Soffittenlampen 2 mit dem üblicherweise geerdeten Leuchtenrohr 3 in Berührung kommen, sind jeweils Hülsen 9 vorgesehen, die die gesamten Umfangsflächen der Kontaktenden 4 umschliessen. Diese Hülsen bestehen vorzugsweise aus einem bis etwa 1200 hitzebeständigen Kunststoff, der elektrisch nicht-leitend ist. Polyacetalharz (POM) ist zwischen -50° und +1500 C hitzebeständig und hochisolierend, und daher als Hülsenmaterial gut geeignet.In order to prevent the contact ends 4 of the festoon lamps 2 from coming into contact with the usually grounded lamp tube 3, sleeves 9 are provided which surround the entire circumferential surfaces of the contact ends 4. These sleeves preferably consist of one to about 120 0 heat-resistant plastic that is electrically non-conductive. Polyacetal resin (POM) is heat-resistant and highly insulating between -50 ° and +150 0 C, and therefore well suited as a sleeve material.

Bei dem dargestellten Ausführungsbeispiel befindet sich zwischen den aufeinander zu gerichteten Kontaktenden zweier Soffittenlampen eine Zwischendruckfeder 7. Man kann diese Zwischendruckfeder 7 jedoch auch weglassen, so dass sich die Spitzen der Kontaktenden 4 der Soffittenlampen 2 direkt berühren und auf Grund der Federwirkung der Druckfeder 5 in gutem Kontakt gehalten werden. Selbstverständlich müsste dann die Hülse 9 entweder etwas verkürzt oder besser noch in ihrem Innendurchmesser vergrössert werden, damit das Hülsenende nicht an den Glasansatz anstösst, sondern die Soffittenlampe mit ihrem Glasmantel mindestens so weit in die Hülse eingeschoben werden kann, dass sich die Spitzen der Kontaktenden 4 berühren.In the illustrated embodiment, an intermediate compression spring 7 is located between the contact ends of two festoon lamps facing each other. However, this intermediate compression spring 7 can also be omitted, so that the tips of the contact ends 4 of the festoon lamps 2 touch directly and are in good condition due to the spring action of the compression spring 5 Be kept in contact. Of course, the sleeve 9 would then either have to be shortened a little, or even better, so that the inside diameter of the sleeve does not abut the glass shoulder, but rather the tubular lamp with its glass jacket can be inserted into the sleeve at least to such an extent that the tips of the contact ends 4 touch.

Auf der rechten Seite sind der Leuchtenkörper, das Leuchtenrohr, die Hülsen und Druckfedern, nicht aber die Soffittenlampe selbst im Querschnitt dargestellt. Auf der linken Seite der Zeichnung ist die erfindungsgemässe Leuchte von aussen zu sehen.An den Leuchtenkörpern bzw. Leuchtenrohrhaltern 6 sind Befestigungsarme 16 und Befestigungslaschen 17 zum Befestigen der Leuchte an der Wand oder an der Decke dargestellt.On the right side, the lamp body, the lamp tube, the sleeves and compression springs, but not the festoon lamp itself, are shown in cross-section. The luminaire according to the invention can be seen from the outside on the left-hand side of the drawing. Fastening arms 16 and fastening lugs 17 for fastening the luminaire to the wall or to the ceiling are shown on the luminaire bodies or luminaire tube holders 6.

Ersichtlich ist der konstruktive Aufwand für die erfindungsgemässe Leuchte denkbar gering. Die Leuchte kann ohne grosse Mehraufwendung und auf einfache Weise mit den gleichen Leuchtenkörper bzw. Leuchtenrohrhaltern unter Verwendung unterschiedlich langer Leuchtenrohre auf einfache Weise verkürzt oder verlängert werden, was bei üblichen Leuchtröhren nicht der Fall ist. Bei der Wahl der Leuchtenrohre gemäss der vorliegenden Erfindung ist lediglich darauf zu achten, dass die Leuchtenrohre in ihrer Länge jeweils um ein ganzzahliges Vielfaches der Länge der Soffittenlampen abgestuft sein müssen.Obviously, the design effort for the lamp according to the invention is extremely low. The lamp can be easily shortened or lengthened with little effort and with the same lamp body or lamp tube holder using lamp tubes of different lengths, which is not the case with conventional fluorescent tubes. When choosing the lamp tubes according to the present invention, it is only necessary to ensure that the lamp tubes must each have an integer multiple of the length of the tubular lamps.

Gegenüber Leuchtstoffröhren mit Leuchtstoffstarterbetrieb hat die erfindungsgemässe Leuchte auch den wesentlichen Vorteil, dass sie mit verschiedenen Spannungen betrieben, also über einen Dimmer regelbar ist und kein Ablass zu Funkeinschaltstörungen gibt.Compared to fluorescent tubes with fluorescent starter operation, the luminaire according to the invention also has the essential advantage that it operates at different voltages, that is to say it can be regulated by means of a dimmer and does not give rise to radio switch-on interference.
