Abstract

The lamp has at least part of the coils of the lamp arranged tightly adjacent to each other in shape fitting manner with no intervening gaps. The tube is blown into its final form in a tool at deformation temperature after winding.

Description

Energiesparlampen mit gewendelten Gasentladungsröhren haben sich in letzter Zeit in zunehmendem Maße wegen ihrer besseren Lichtverteilung durchgesetzt. Ein wesentlicher weiterer Vorteil ist die Möglichkeit, auf dem gleichen Lampenvo­ lumen höhere Lichtleistungen unterzubringen.Energy saving lamps with coiled gas discharge tubes have become the latter Time increasingly enforced because of their better light distribution. Another important advantage is the possibility of using the same lamp lumen to accommodate higher light outputs.

Nach wie vor gilt jedoch der Grundsatz, daß bei gleichem Lichtstrom Gasentla­ dungslampen größer sind als herkömmliche Glühlampen.However, the principle still applies that gas discharge at the same luminous flux lamps are larger than conventional incandescent lamps.

Die bisher auf dem Markt befindlichen Energiesparlampen mit Gasentladungs­ röhren wurden ausschließlich so gewickelt, daß die Windungen einen möglichst gleichmäßigen Abstand voneinander besitzen.The energy-saving lamps with gas discharge that were previously on the market tubes were only wound in such a way that the coils were as possible have an even distance from each other.

Um die Baulängen der gewendelten Gasentladungsröhren zu verringern, wird er­ findungsgemäß vorgeschlagen, zumindest einen Teil der Windungen ohne Zwi­ schenraum formschlüssig nebeneinander anzuordnen.In order to reduce the overall length of the coiled gas discharge tubes, it is proposed according to the invention, at least part of the turns without intermediate arrange space next to each other in a form-fitting manner.

Die Vorteile einer derartigen Ausführung sind offenkundig:
The advantages of such a design are obvious:

  • - Die Baulänge wird verringert.- The overall length is reduced.
  • - Der Aufbau der Wendel ist wesentlich solider.- The structure of the helix is much more solid.
  • - Das von der Wendel abgegebene Licht ist eine geschlossene Lichtfläche.- The light emitted by the filament is a closed light surface.
  • - Die Herstellung der Wendeln wird vereinfacht. - The manufacture of the helices is simplified.  
  • - Ein Blasen der Gasentladungsröhren in einer einfachen Form ist möglich.- It is possible to blow the gas discharge tubes in a simple form.

Die Fig. 1 zeigt ein Beispiel einer bisherigen Doppelwendel im Vergleich mit Fig. 2, die die gleiche Wendel in erfindungsgemäßer Ausführung zeigt. Fig. 1 shows an example of a prior art double helix compared with Fig. 2, showing the same helix in the inventive embodiment.

Zum besseren Verständnis ist in Fig. 3 die Ansicht der Wendel in axialer Richtung dargestellt.For a better understanding, the view of the helix is shown in the axial direction in FIG. 3.

Fig. 4 zeigt schematisch den Aufbau einer Blasform zur Fertigstellung der Gasent­ ladungsröhre im Schnitt. Fig. 4 shows schematically the structure of a blow mold for the completion of the gas discharge tube in section.

Das Ausführungsbeispiel zeigt eine doppelt-gegensinnig gewickelte Wendel und entspricht der am häufigsten auf dem Markt anzutreffenden Form. Dieses Beispiel ist jedoch in keiner Art als Einschränkung des Erfindungsgedankens aufzufassen. Das Prinzip der Erfindung kann ebenso bei einfachen Wendeln erfolgreich benützt werden. Auch die Lage der Wendel im Lampendesign ist beliebig wählbar, gleich­ gültig ob die Wendelachse mit der Lampenachse identisch ist oder dazu senkrecht oder schräg steht.The embodiment shows a double-wound coil and corresponds to the most common form on the market. This example is not to be interpreted in any way as a limitation of the inventive concept. The principle of the invention can also be used successfully with simple helices become. The position of the filament in the lamp design can also be selected as desired Valid whether the filament axis is identical to the lamp axis or perpendicular to it or stands at an angle.

Zum Ausführungsbeispiel noch folgende Erläuterungen, um den Erfindungsgedan­ ken besser verstehen zu können.For the exemplary embodiment, the following explanations to the inventive concept to understand better.

Der Größenvergleich einer herkömmlichen Doppelwendel Fig. 1 mit einer erfin­ dungsgemäßen Ausführung Fig. 2 zeigt den enormen Größenunterschied. Die neue Wendel wirkt nicht nur kompakter, sondern ist auch mechanisch wider­ standfähiger. Das homogene Lichtfeld ist konzentrierter und benötigt keine mat­ tierte Verkleidung, wie dies bei herkömmlichen Glühlampen oft der Fall ist. Es entspricht auch mehr dem gewohnten Eindruck einer herkömmlichen Glühlampe.The size comparison of a conventional double helix Fig. 1 with an inventive design Fig. 2 shows the enormous size difference. The new spiral not only looks more compact, but is also more mechanically resistant. The homogeneous light field is more concentrated and does not require a matt coating, as is often the case with conventional light bulbs. It also corresponds more to the usual impression of a conventional light bulb.

Die Windungen (1) in Fig. 1 sind mit Abstand gewickelt, zum Unterschied der Win­ dungen (2) in Fig. 2., wo sie formschlüssig aneinander liegen. Bei der Herstellung solcher Wendeln muß auch nicht durch besondere spiralförmige Einrichtungen für einen gleichmäßigen Abstand gesorgt werden, die Windungen können einfach und problemlos nebeneinander gewickelt werden.The turns ( 1 ) in Fig. 1 are wound at a distance, in contrast to the Win ( 2 ) in Fig. 2, where they are positively against each other. In the production of such coils, it is not necessary to ensure a uniform spacing by means of special spiral devices, the windings can be easily and easily wound next to one another.

Bei dem dargestellten Beispiel einer Doppelwendel sind die beiden offenen Rohrenden (3) am selben Ende der Wendel, da im Scheitelpunkt (4) die Steigung der Wendel umkehrt. Dies ist in Fig. 3 deutlich zu erkennen.In the illustrated example of a double helix, the two open tube ends ( 3 ) are at the same end of the helix, since the gradient of the helix reverses at the apex ( 4 ). This can be clearly seen in FIG. 3.

Da keine spiralförmigen Einrichtungen benötigt werden, genügt ein glatter Mittel­ dorn (6) mit einer Aussparung (7) zur Aufnahme des Scheitelpunktes (4), um bei der Herstellung des Gasentladungsgefäßes die Windungen (5) der Wendel aufzunehmen. Auch das Außenwerkzeug (8), das in der Trennfuge (9) geteilt ist, benötigt keine besondere Profilierung. Eine glatte, zylindrische oder leicht koni­ sche Oberfläche genügt, um dem gewendelten Glasrohr seine endgültige Form durch Einpressen von Luft oder einem Schutzgas durch die Luftzuführungen (10) zu geben. Dadurch verliert das fertige Produkt das Aussehen eines handwerklich hergestellten Artikels. Auch die eventuell angeformten Profilierungen der zunächst runden Glasrohre verleihen dem Produkt ein besonderes Aussehen der Perfektion.Since no spiral devices are required, a smooth central mandrel ( 6 ) with a recess ( 7 ) for receiving the apex ( 4 ) is sufficient to accommodate the turns ( 5 ) of the coil during the manufacture of the gas discharge vessel. The outer tool ( 8 ), which is divided in the parting line ( 9 ), does not require any special profiling. A smooth, cylindrical or slightly conical surface is sufficient to give the coiled glass tube its final shape by injecting air or a protective gas through the air inlets ( 10 ). As a result, the finished product loses the appearance of a handcrafted article. The possibly molded profiles of the initially round glass tubes also give the product a special appearance of perfection.

Bei der großen Zahl der Anwendungsmöglichkeiten des Erfindungsgedankens ist es nicht möglich, alle Vorteile im Detail darzustellen, aber aus der beschriebenen Beispiel lassen sich ohne weiteres solche zusätzlichen Verbesserungen erkennen und ableiten.Given the large number of possible uses of the inventive concept it is not possible to show all the advantages in detail, but from the described For example, such additional improvements can be easily recognized and deduce.
