Description
Bei der Herstellung von Glühlampen spielen Fangstoffe (Getter) eine wesentliche Rolle. Es ist bekannt; Phosphor und Phosphorverbindungen oder ähnliche Stoffe zu benützen, die vor dem Zusammenbau der Glühlampe auf das sogenannte Gestell und auf den Leuchtdraht selbst aufgebracht und dann während des Pumpprozesses oder nach dem Abschmelzen verdampft werden. Die Anwendung solcher Fangstoffe setzt jedoch eine sehr gute Vorentgasung aller eingebauten Metallteile voraus. Bei Speziallampen kann diese Vorentgasung einen erheblichen Aufwand bedeuten. Bei Verwendung von Fangstoffen aus Metalldampf kann man auf eine Vorentgasung der Metallteile weitgehend verzichten, doch hat man aus Gründen der Lichtabsorption das Einbringen von Metalldämpfen in Glühlampen bisher abgelehnt.In the manufacture of light bulbs, catches (getters) play a role essential role. It is known; Phosphorus and phosphorus compounds or the like Use materials that are placed on the so-called frame before assembling the light bulb and applied to the filament itself and then during the pumping process or be evaporated after melting. However, the use of such catchments continues a very good pre-degassing of all built-in metal parts. With special lamps this pre-degassing can mean considerable effort. When using catching materials from metal vapor one can largely dispense with a pre-degassing of the metal parts, but you have to introduce metal vapors in for reasons of light absorption Incandescent lamps rejected so far.
Vorliegende Erfindung gestattet nun die Anwendung von Fangstoffen aus Metalldampf auch in der Glühlampenfertigung, insbesondere aber bei der Herstellung von Speziallampen dadurch, daß der Getterstoff im unteren, meistens durch den Sockel abgedeckten Teil der Lampe angebracht und sodann durch elektrisch zugeführte Wärme verdampft wird.The present invention now allows the use of traps from metal vapor also in the manufacture of incandescent lamps, but especially in the manufacture of special lamps in that the getter material is in the lower part, mostly through the base covered part of the lamp attached and then by electrically supplied heat is evaporated.
Als Fangstoff wird beispielsweise Barium in Eisenhülsen verwendet. Das Material wird in Längen von beispielsweise etwa i bis 2 mm und einem Durchmesser von i mm in eine Drahtwendel im unteren Teil der Lampe eingelegt und während des Pumpprozesses mittels Stromdurchgang durch die Wendel verdampft. In der Praxis hat es sich gezeigt, daß z. B. Zweifadenlampen, die verhältnismäßig viel Metall im kleinen Vakuumraum aufweisen, bei Anwendung des Verfahrens nach der Erfindung ohne jegliche Vorentgasung der Metallteile nach der Getterung mit Barium einwandfrei mit hoher Lebensdauer brennen. Es hat sich weiter gezeigt, daß im Betrieb durch Stromstöße frei werdende Gase ebenfalls absorbiert werden und dadurch eine erhöhte Betriebssicherheit gewährleistet wird. Die Dosierung des Fangstoffes kann durch Stromregulierung oder durch vorher bestimmte Menge übersichtlich gut vorgenommen werden.Barium, for example, is used as a catching material in iron shells. The material is available in lengths of, for example, about 1 to 2 mm and a diameter of i mm inserted into a wire coil in the lower part of the lamp and during the The pumping process is evaporated by the passage of current through the coil. In practice it has it has been shown that z. B. two-filament lamps that contain a relatively large amount of metal in the small Have vacuum space, when using the method according to the invention without any Pre-degassing of the metal parts after gettering with barium flawlessly with high Burn life. It has also been shown that during operation by power surges released gases are also absorbed and thereby increased operational safety is guaranteed. The dosage of the catch material can be regulated by current or can be done clearly and well through a previously determined amount.
An Hand der Abb. i (Zweifadenlampe) wird die Erfindung näher erläutert. Ein mit vier Elektrodendurchführungen versehener Quetschfuß i dient dem bekannten Aufbau der Lampe, wozu im betrieblichenAnwendungsfalle drei Elektroden erforderlich sind. Eine vierte Elektrode 2 hat den Zweck, die Stromverbindung zur Wendel 3 herzustellen. Der Getterniederschlag erfolgt im unteren Teil der Lampe 4. Abb. II zeigt den normalen Aufbau einer Zweifadenlampe ohne zusätzliche Elektrode, hierbei ist die Wendel 3 an zwei betriebsmäßig benutzte Elektroden angeschlossen. Während des Getterprozesses wird diese Wendel so stark erhitzt, daß sie einseitig durchbrennt und dadurch die normale Stromzuleitung zu den Glühfäden freigibt.The invention is explained in more detail with reference to Fig. I (two-filament lamp). A pinch foot i provided with four electrode feed-throughs is used for the known one Structure of the lamp, which requires three electrodes in operational use are. A fourth electrode 2 has the purpose of establishing the current connection to the filament 3. Getter precipitation occurs in the lower part of lamp 4. Fig. II shows the normal Construction of a two-filament lamp without an additional electrode, here the filament is 3 connected to two operational electrodes. During the getter process this filament is heated so much that it burns through on one side and thereby the releases normal power supply to the filaments.
Bei Verwendung besonderer Hilfselektroden für die Stromzuführung zur Wendel 3 kann die Wendel aus einem nicht oder nur bei sehr hohen Temperaturen schmelzenden Stoff, z. B. aus Molybdän oder Wolfram, gefertigt sein. Im Falle der Alb. 1I besteht sie zweckmäßig aus Nickel.When using special auxiliary electrodes for the power supply to the Helix 3 can consist of a helix that does not melt or melts only at very high temperatures Fabric, e.g. B. made of molybdenum or tungsten. In the case of the Alb. 1I exists they suitably made of nickel.
