Abstract

The fluorescent light tube has a spiral element made of a glass with a relatively high melting point, contained within a light tube made of a glass with a relatively low melting point, which is heated at a required point to allow it to be shaped, the spiral element preventing its implosion.

Description

Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbe­ griff des Anspruchs 1.The invention relates to a device according to the Oberbe handle of claim 1.

Die heutige Herstellungstechnologie z. B. von Hochspannungsleucht­ stoffröhren auf dem Sektor der Leuchtreklame ist es,bei einer einen Buchstaben od. eine Schrift nachzeichnenden Lampe als ersten Arbeitsgang den Lampenkolben,die Röhre zu formen.Today's manufacturing technology such. B. of high voltage light tubes in the neon sign sector is at a a letter or a tracing lamp as the first Work the lamp bulb to shape the tube.

Alle anderen erforderlichen Schritte erfolgen anschließend an dem nun sperrigen Teil ebenfalls von Hand(Leuchtstoff beschicken, Elektroden ansetzen, Luft abpumpen, Quecksilber füllen. . .). Wesentlich günstiger wäre es, auf eine Palette fertiger Lampen in den verschiedensten Längenausführungen zurückgreifen zu können, die sich nach Erwärmung des Glaskolbens beliebig formen lassen. Das Problem ist es hier,daß eine Lampe ihres Vakuums wegen dabei implodieren würde. Der formbare Leuchtstofflampenkolben soll eine Lösung dieses Problems anbieten.All other necessary steps then take place on the now also bulky part by hand (feed fluorescent, Put on electrodes, pump out air, fill mercury. . .). It would be much cheaper to have a range of finished lamps to be able to use different lengths, which can be shaped as desired after heating the glass bulb. The problem here is that a lamp is there because of its vacuum would implode. The malleable fluorescent lamp bulb is said to be one Offer a solution to this problem.

Auch würde er in der bisherigen Herstellungstechnologie eine große Erleichterung beim Arbeitsgang des Kolbenformens bedeuten. He would also be one in the previous manufacturing technology great relief in the piston molding operation.  

Der formbare Leuchtstofflampenkolben besitzt folgenden Aufbau. Der eine Bestandteil ist zunächst-der gewöhnliche Lampenkolben, dessen Schmelzpunkt möglichst niedrig sein sollte. An ihn an­ liegend od. in ihn integriert ist der Spiralteil bestehend aus einem Glas mit(vermeintlich)höherem Schmelzpunkt und hoher Elastizität, Abbildung. Dieser Körper läßt sich im festen Zustand biegen ohne dabei seinen Querschnitt zu ändern.The formable fluorescent lamp bulb has the following structure. One component is initially - the ordinary lamp bulb, whose melting point should be as low as possible. To him lying or integrated in it is the spiral part consisting of a glass with (supposedly) higher melting point and higher Elasticity, illustration. This body can be in the solid state bend without changing its cross section.

Führt man nun einem formbaren Leuchtstoff Lampenkolben eine definierte Wärmemenge zu,so stellt sich der Punkt ein,an dem das Kolbenmaterial mit niedrigerem Schmelzpunkt formbar wird, jedoch keine Implosion stattfindet,da der Spiralteil den Kolbenkörper noch stabilisiert.If you now insert a formable fluorescent lamp bulb to a defined amount of heat, the point at which the piston material with a lower melting point becomes malleable, however, no implosion takes place because the spiral part of the Piston body still stabilized.

Claims (1)

Formbarer Leuchtstofflampenkolben,dadurch gekennzeichnet,daß durch die Anbringung eines bevorzugt aus Glas bestehenden Spiralteils am Lampenkolben-im Normalfall innenliegend u. einen Verformbarkeitspunkt besitzend der bei der Wärmezufuhr von außen auf den Lampenkolben eine höhere Temperatur er­ fordert als der des Lampenkolbens­ eine Implosion einer schon Vakuum gepumpten Lampe verhindert wird bzw. eine leichtere Formbearbeitung des bloßen Kolbens erfolgen kann.Formable fluorescent lamp bulb, characterized in that, by attaching a spiral part, preferably made of glass, to the lamp bulb - in the normal case internally and. possessing a deformability point which, when the heat is supplied to the lamp bulb from the outside, demands a higher temperature than that of the lamp bulb prevents an implosion of a lamp which has already been vacuum-pumped, or the bare bulb can be shaped more easily.
