Description

Verfahren zur Herstel lung eines Kappenbandes für Entladungslampen und Kappenband für EntladungslampenProcess for the manufacture of a cap tape for discharge lamps and cap tape for discharge lamps
Die Erfindung betrifft ein Verfahren zur Herstellung eines Kappenbandes für Entladungslampen nach dem Oberbegriff des Anspruchs 1 sowie ein Kappen¬ band nach dem Oberbegriff des Anspruchs 8.The invention relates to a method for producing a cap strip for discharge lamps according to the preamble of claim 1 and a cap strip according to the preamble of claim 8.
Aus der veröffentlichten ungeprüften japanischen Patentanmeldung 6-96728 ist eine Niederdruck-Quecksilberdampf-Entladungslampe bekannt. Diese Entladungslampe weist eine metallische Ringkappe auf, die aus zwei metalli¬ schen Ringteilstücken besteht, wobei ein Teilstück eine Quecksilber abgebende Funktion hat, während das andere metallische Teilstück keine derartige Funk¬ tion hat. Das erstgenannte metallische Teilstück besteht aus einem nickelüber¬ zogenen Eisenträger und aus einer Quecksilberlegierung, die aus einem auf dem Träger aufgebrachten Quecksilbertitan-Legierungspulver besteht.A low-pressure mercury vapor discharge lamp is known from published unexamined Japanese patent application 6-96728. This discharge lamp has a metallic ring cap, which consists of two metallic ring sections, one section having a mercury-releasing function, while the other metallic section has no such function. The first-mentioned metallic section consists of a nickel-coated iron carrier and a mercury alloy which consists of a mercury titanium alloy powder applied to the carrier.
Die Quecksilberlegierung ist auf einer Seite, der Innenseite des Ringteilstücks angeordnet, während Getter auf der anderen Seite, der Außenseite des Ring¬ teilstücks angeordnet ist. Die in die Entladungslampe einzubringende Queck¬ silbermenge wird durch Veränderung der Länge des ersten Teilstücks be¬ stimmt. Wenn also die Quecksilbermenge zu erhöhen ist, wird die Länge des erstgenannten metallischen Teilstücks vergrößert.The mercury alloy is arranged on one side, the inside of the ring section, while getters are arranged on the other side, the outside of the ring section. The amount of mercury to be introduced into the discharge lamp is determined by changing the length of the first section. If the amount of mercury is to be increased, the length of the first-mentioned metallic section is increased.
Die Ringkappe der vorbekannten Entladungslampe ist also nicht einstückig ausgebildet, sondern besteht aus einer Mehrzahl von Komponenten. Hier¬ durch erhöhen sich sowohl die Kosten für die Herstellung der Ringkappe als auch die Kosten für die Herstellung der Entladungslampe. Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art und ein Kappenband anzugeben, das eine kostengünstigere Herstellung ermöglicht.The ring cap of the known discharge lamp is therefore not formed in one piece, but consists of a plurality of components. This increases both the costs for the manufacture of the ring cap and the costs for the manufacture of the discharge lamp. Based on this prior art, the invention has for its object to provide a method of the type mentioned and a cap band, which enables a more cost-effective production.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren nach dem An¬ spruch 1 und durch ein Kappenband nach dem Anspruch 8 gelöst.This object is achieved according to the invention by a method according to claim 1 and by a cap band according to claim 8.
Die Erfindung ist mit dem Vorteil verbunden, daß aus einer vorgegebenen Länge des nach dem erfindungsgemäßen Verfahren hergestellten Kappenban- des eine Vielzahl von Teilstücken herstellbar ist, wobei jedes Teilstück in einfa¬ cher Weise insbesondere zu einer einstückigen Ringkappe verarbeitet werden kann.The invention is associated with the advantage that a multiplicity of sections can be produced from a predetermined length of the cap band produced by the method according to the invention, wherein each section can be processed in a simple manner, in particular to form a one-piece ring cap.
Beispielsweise beträgt die Breite des bei dem erfindungsgemäßen Verfahren verwendeten Trägerbandes etwa 12 bis 55 mm. Geht man davon aus, daß für eine Ringkappe ein 5 mm breites Kappenband vorzusehen ist, lassen sich aus einem laufenden Meter des Trägerbandes nach dem erfindungsgemäßen Ver¬ fahren 200 Kappenbänder herstellen, es sind also 199 Schnitte erforderlich. Im Stand der Technik, bei dem ein Trägerband eine Breite von 5 bis 7 mm hat, las- sen sich für einen vollen Ringkappenumfang von 42 mm lediglich 23 Kappen¬ bänder herstellen.For example, the width of the carrier tape used in the method according to the invention is approximately 12 to 55 mm. If it is assumed that a 5 mm wide cap band is to be provided for an annular cap, 200 cap bands can be produced from a running meter of the carrier band according to the method according to the invention, so 199 cuts are required. In the prior art, in which a carrier tape has a width of 5 to 7 mm, only 23 cap tapes can be produced for a full ring cap circumference of 42 mm.
Das Aufbringen von Getter und Quecksilberlegierung ist um Faktoren teurer als das Material. Wenn man erfindungsgemäß quer zur Materialaufbringrich- tung schneidet und außerdem noch einseitig beschichtet, ist die Herstellge¬ schwindigkeit für ein Teilstück (Kappenband) bei gleicher Maschinenge¬ schwindigkeit um Faktoren (je nach Breite BT, Figuren 3, 4) höher.The application of getters and mercury alloy is several times more expensive than the material. If, according to the invention, one cuts transversely to the material application direction and additionally also coats one side, the production speed for a section (cap belt) is higher by factors (depending on the width BT, FIGS. 3, 4) with the same machine speed.
Nach einer weiteren vorteilhaften Ausführungsform des erfindungsgemäßen Verfahrens wird das Kappenband durch einseitige Beschichtung des Träger- bands mit dem mindestens einen in die Entladungslampe einzubringenden Material, insbesondere mit zwei Materialien, nämlich mit einer Quecksilberle¬ gierung und Getter, hergestellt werden. Dies hat unter anderen den Vorteil, daß die Beschichtung der beiden Materialien auf dem Trägerband gleichzeitig erfolgen kann.According to a further advantageous embodiment of the method according to the invention, the cap band is coated on one side by coating the carrier bands with the at least one material to be introduced into the discharge lamp, in particular with two materials, namely with a mercury alloy and getter. Among other things, this has the advantage that the coating of the two materials on the carrier tape can take place simultaneously.
Die Erfindung wird nun anhand der Zeichnung beschrieben.The invention will now be described with reference to the drawing.

Die in Fig. 1 dargestellte Ringkappe für eine Entladungslampe besteht aus ei¬ nem zweiteiligen ovalen Ring 30, der aus einem ersten metallischen Stück 31 und einem zweiten metallischen Stück 32 besteht. Das erste metallische Stück kann durch ein Kappenband gebildet sein, das in Fig. 2 dargestellt ist. In Fig. 3 ist ein Ausführungsbeispiel eines nach dem erfindungsgemäßen Ver¬ fahren hergestellten Kappenbandes dargestellt. Dabei wird ein Trägerband 1 (Metallband), das die Länge LB hat, mit mindestens einem in die Entladungs¬ lampe insbesondere durch Erhitzen einzubringenden Material beschichtet. Vorzugsweise wird das Trägerband 1, das beispielsweise aus nickelbeschich¬ tetem Eisenblech besteht, mit einer Quecksilberlegierung 2 und/oder Getter¬ material 3 z.B. durch Aufwalzen beschichtet. Die Breite BB des Trägerbandes 1 wird so gewählt, daß sie gleich dem Umfang der jeweiligen Ringkappe der Entladungslampe entspricht.The ring cap shown in FIG. 1 for a discharge lamp consists of a two-part oval ring 30, which consists of a first metallic piece 31 and a second metallic piece 32. The first metallic piece can be formed by a cap band, which is shown in FIG. 2. 3 shows an embodiment of a cap band produced by the method according to the invention. A carrier tape 1 (metal tape), which has the length LB, is coated with at least one material to be introduced into the discharge lamp, in particular by heating. The carrier tape 1, which consists, for example, of nickel-coated iron sheet, is preferably coated with a mercury alloy 2 and / or getter material 3, for example by rolling. The width BB of the carrier tape 1 is selected so that it corresponds to the circumference of the respective ring cap of the discharge lamp.
Das nach dem erfindungsgemäßen Verfahren hergestellte Kappenband 4 kann durch einseitige oder beidseitige Beschichtung des Trägerbandes gebildet wer¬ den. Beispiele für diese Ausführungsformen des Kappenbandes sind in den Fig. 3 und 4 dargestellt. Fig. 3 zeigt ein Kappenband, wobei das Trägerband 1 auf der einen Seite mit Gettermaterial 3 und auf der anderen Seite mit einer Quecksilberlegierung 2 beschichtet ist. Von dem Trägerband 1 wird quer zu seiner Längsrichtung LB (die in der Regel die Materialaufbringrichtung ist) ein Teilstück 5 abgetrennt, das das Kappenband 4 für eine Entladungslampe bildet. Das Teilstück 5 bzw. das Kappenband 4 ist über seine gesamte Breite BT mit mindestens einem Material beschichtet.The cap tape 4 produced by the method according to the invention can be formed by coating the carrier tape on one or both sides. Examples of these embodiments of the cap band are shown in FIGS. 3 and 4. 3 shows a cap tape, the carrier tape 1 being coated on one side with getter material 3 and on the other side with a mercury alloy 2. A section 5, which forms the cap band 4 for a discharge lamp, is separated from the carrier band 1 transversely to its longitudinal direction LB (which is generally the direction of material application). The section 5 or the cap band 4 is coated with at least one material over its entire width BT.
Das nach dem erfindungsgemäßen Verfahren hergestellte Kappenband hat beispielsweise eine Länge LT im Bereich von etwa 12 bis 55 mm. Die jeweilige Länge LT entspricht, wie bereits beschrieben, dem Umfang der jeweiligen Ringkappe der Entladungslampe (z.B. 48 mm bei einer T8-Niederdruck- Quecksilberdampf-Entladungslampe mit einem Durchmesser von 8/8 Inch).The cap band produced by the method according to the invention has, for example, a length LT in the range from approximately 12 to 55 mm. As already described, the respective length LT corresponds to the circumference of the respective ring cap of the discharge lamp (e.g. 48 mm in the case of a T8 low-pressure mercury vapor discharge lamp with a diameter of 8/8 inches).
Das in Fig. 4 dargestellte, nach dem erfindungsgemäßen Verfahren hergestellte Kappenband ist einseitig beschichtet. Gettermaterial und die Quecksilberle- gierung sind also auf derselben Seite des Kappenbandes angeordnet. Das in Fig. 4 dargestellte Kappenband hat eine Breite von 44 mm.The cap band shown in FIG. 4 and produced by the method according to the invention is coated on one side. Getter material and the mercury Allocation are thus arranged on the same side of the cap band. The cap band shown in Fig. 4 has a width of 44 mm.
In den Fig. 3 und 4 ist jeweils an der rechten Seite des Trägerbandes 4 ein Ab- schnitt 5 von 5 mm Breite dargestellt. Erfindungsgemäß werden aus dem lau¬ fenden Trägerband, beispielsweise wie es in den Fig. 3 und 4 dargestellt ist, Teilstücke 5 geschnitten, die jeweils eine Breite BT von 5 mm (Länge LT des Teilstückes 5 = Breite BB des Trägerbands 1 = Umfang der Ringkappe = 44 mm) haben. Durch die Bestimmung der Teilstückbreite BT, im vorliegenden Fall 5 mm, wird die Menge des in die Entladungslampe durch Erhitzung einzu¬ bringenden Materials (Quecksilberlegierung und /oder Getter) bestimmt. An¬ dererseits wird die Menge des pro Trägerbandlängeneinheit aufzubringenden Materials im Hinblick auf eine mögliche feste Breite BT des Kappenbandes bestimmt.3 and 4, a section 5 of 5 mm width is shown on the right side of the carrier tape 4. According to the invention, sections 5 are cut from the running carrier tape, for example as shown in FIGS. 3 and 4, each of which has a width BT of 5 mm (length LT of section 5 = width BB of the carrier tape 1 = circumference of the ring cap = 44 mm). By determining the section width BT, in the present case 5 mm, the amount of material to be introduced into the discharge lamp by heating (mercury alloy and / or getter) is determined. On the other hand, the amount of the material to be applied per unit tape length unit is determined with regard to a possible fixed width BT of the cap tape.
Ein nach dem beschriebenen erfindungsgemäßen Verfahren hergestelltes Kap¬ penband wird zur Herstellung einer Entladungslampe in der Weise verwen¬ det, daß es in die Entladungslampe eingeführt und in dieser befestigt wird.A cap strip produced according to the described method according to the invention is used to produce a discharge lamp in such a way that it is inserted into the discharge lamp and fastened in it.
Erfindungsgemäß hat dieses Kappenband eine Länge, die gleich dem Umfang einer Ringkappe der Entladungslampe ist (z.B. 44 mm). Die Breite des Teil¬ stücks bzw. des Kappenbandes beträgt z.B. 5 mm, wobei diese Breite in Ab¬ hängigkeit des in die Entladungslampe einzubringenden Materials gewählt wird. Das Trägerband wird also in der Weise beschichtet, daß auf einem für eine Entladungslampe bestimmten Teilstück des Trägerbandes mit einer vorbe¬ stimmten Breite BT von z.B. 5 - 7 mm die für die Entladungslampe bestimmte Menge des oder der Materialien aufgebracht ist.According to the invention, this cap band has a length which is equal to the circumference of a ring cap of the discharge lamp (e.g. 44 mm). The width of the section or the cap band is e.g. 5 mm, this width being selected as a function of the material to be introduced into the discharge lamp. The carrier tape is thus coated in such a way that on a section of the carrier tape intended for a discharge lamp with a predetermined width BT of e.g. 5 - 7 mm the amount of the material or materials intended for the discharge lamp is applied.
Das Teilstück wird evtl. in die vorbestimmte Form gebogen, in die Entla- dungslampe eingeführt und dort befestigt. Eine erfindungsgemaße Entladungslampe weist damit ein Kappenband 4 auf, wie es zuvor beschrieben bzw. beansprucht ist.The section may be bent into the predetermined shape, inserted into the discharge lamp and fastened there. A discharge lamp according to the invention thus has a cap band 4, as described or claimed above.
Die in Figur 5 dargestellte Ringkappe besteht ausschließlich aus einem erfin¬ dungsgemäßen Kappenband 4, das an seinen Enden verschweißt ist, während die in Figur 6 dargestellte Ringkappe aus einem erfindungsgemäßen Kappen¬ band und einem weiteren Band besteht, wobei Kappenband 4 und weiteres Band miteinander verschweißt sind. The ring cap shown in FIG. 5 consists exclusively of a cap band 4 according to the invention which is welded at its ends, while the ring cap shown in FIG. 6 consists of a cap band according to the invention and a further band, cap band 4 and another band being welded to one another are.
