Bei gasgefüllten elektrischen Glühlampen, insbesondere bei solchen, die mit einem Schirm versehen sind, z. B. bei Autolampen, kann der in der Lampe vorgesehene Schirm im Betrieb der Lampe gasförmigen Wasserstoff abgeben. Es ist bekannt, daß Wasserstoff infolge der Wasserdampfreaktion durch den sogenannten Kreisprozeß den Glühfaden beschädigt und die Lebensdauer der Lampe verkürzt. Man hat schon versucht, diesen Nachteil durch die Verwendung verschiedener Getter zu beseitigen. Die Anwendung eines metallischen Zirkongetters ist verbreitet, weil die Getterwirkung des Zirkons bereits seit mehreren Jahrzehnten bekannt und festgestellt ist, daß Zirkon die verschiedenen Gase optimal bei einer jeweils anderen Temperatur absorbiert. Es wurde auch gefunden, daß die Anwendung des Zirkongetters in Glühlampen an Stellen mit einer Temperatur von 200 bis 600° C vorteilhaft ist, da der Getter bei dieser Temperatur den schädlichen Wasserstoff und den Sauerstoff ziemlich gut, den in der Lampe notwendigen Stickstoff jedoch nicht in ausschlaggebenden Mengen absorbiert. Aus der einschlägigen Literatur geht hervor, daß Zirkon nicht imstande ist, Kohlenmonoxyd und im allgemeinen Kohlenwasserstoffe in ansehnlichen Mengen zu absorbieren. Weiterhin ist bekannt, daß man in Glühlampen als Getter verschiedene Metallnitride verwenden kann. Diese Nitride, wie z. B. Zirkonnitrid oder Bornitrid, erleiden aber im allgemeinen beim Betrieb der Lampe eine thermische Zersetzung, so daß sie ihre Wirkung eigentlich als Metallgetter ausüben. Sie geben im Betrieb Stickstoff ab.In the case of gas-filled electric incandescent lamps, especially those that are provided with a screen, e.g. B. In the case of car lamps, the screen provided in the lamp can produce gaseous hydrogen when the lamp is in operation hand over. It is known that hydrogen as a result of the water vapor reaction through the so-called cycle process Damage the filament and shorten the life of the lamp. One has already tried this Eliminate disadvantage by using different getters. The application of a metallic zirconia getter is widespread because the getter effect of zircon has been known and established for several decades is that zirconia optimally absorbs the various gases at a different temperature. It it was also found that the use of zirconia in incandescent lamps in places with a temperature from 200 to 600 ° C is advantageous because the getter removes the harmful hydrogen and oxygen at this temperature pretty good, but does not absorb the nitrogen required in the lamp in significant quantities. The relevant literature shows that zircon is incapable of producing carbon monoxide and in general To absorb hydrocarbons in considerable quantities. It is also known that in incandescent lamps can use various metal nitrides as getter. These nitrides, such as. B. zirconium nitride or boron nitride, but generally suffer a thermal decomposition during operation of the lamp, so that they take their effect actually exercise as a metal getter. They give off nitrogen during operation.
Es ist nun gefunden worden, daß die Getterwirkung des Zirkons nicht in jeder Beziehung befriedigt. Im Gegensatz zu den aus der älteren Literatur ersichtlichen Angaben ist festgestellt, daß Zirkon den Stickstoff, den Wasserstoff und den Sauerstoff optimal bei einander naheliegenden Temperaturen absorbiert. Der Unterschied zwischen den optimalen Werten beträgt etwa 50° C. Wenn man also den Zirkongetter in der Lampe an einer Stelle anordnet, an welcher die Absorptionsfähigkeit des Zirkons für Wasserstoff bzw. Sauerstoff optimal ist, so wird sich im Laufe eines längeren Betriebes der Lampe die Temperatur an dieser Stelle naturnotwendig in einem gewissen Maße erhöhen, und das Optimum wird für den Stickstoff den vorteilhaftesten Wert erreichen. Wenn das Zirkon aber den in der Gasfüllung der Lampe in einigen Prozenten vorhandenen Stickstoff absorbiert, so finden in einer Lampe mit Edelgasfüllung, insbesondere wenn dieses Edelgas Krypton enthält, Überschläge statt.It has now been found that the getter effect of zirconium is not satisfactory in every respect. In contrast to the information apparent from the older literature it is established that zircon is the nitrogen, the Hydrogen and oxygen are optimally absorbed at temperatures that are close to one another. The difference between the optimal values is about 50 ° C. So if you put the zirconia in the lamp on a Place where the zirconium's absorption capacity for hydrogen or oxygen is optimal, so the temperature at this point will naturally increase to a certain extent in the course of longer operation of the lamp Increase measurements, and the optimum will reach the most favorable value for nitrogen. if but the zirconium absorbs a few percent of the nitrogen present in the gas filling of the lamp, so flashovers take place in a lamp with a noble gas filling, especially if this noble gas contains krypton.
Um diesen Nachteil zu vermeiden, ist nunmehr nach einer Verbesserung gesucht, die auch gefunden wurde und die hauptsächlich darin besteht, daß bei einer gasgefüllten elektrischen Glühlampe, insbesondere mit einem Schirm versehenen gasgefüllten Glühlampe, z. B. einer Autolampe, deren Gasfüllung mindestens bis zu 90% ausIn order to avoid this disadvantage, an improvement is now being sought, which has also been found and which consists mainly in the fact that in a gas-filled electric incandescent lamp, in particular with a screen provided gas-filled incandescent lamp, e.g. B. a car lamp whose gas filling is at least up to 90% off

Edelgasen besteht, die Lampe erfindungsgemäß einen Getterstoff enthält, welcher die die Qualität der Lampe schädlich beeinflussenden Komponenten der nicht edlen Gase, insbesondere Wasserstoff, Sauerstoff und eventuell Kohlenmonoxyd bzw. Kohlenwasserstoffe, aus dem Gasraum der Lampe absorbiert, sowie einen weiteren Getterstoff, welcher gewährleistet, daß das Verhältnis der zum Betrieb der Lampe erwünschten Komponente der nicht edlen Gase, insbesondere das Verhältnis des Stickstoffes zu den edlen Gasen, sich im Wasser nicht ändert.There is noble gases, the lamp according to the invention contains a getter substance, which the quality of the lamp harmful components of the non-noble gases, especially hydrogen, oxygen and possibly Carbon monoxide or hydrocarbons, absorbed from the gas space of the lamp, as well as another getter substance, which ensures that the ratio of the components desired for operating the lamp is not noble gases, especially the ratio of nitrogen to noble gases, does not change in water.
Der die schädlichen Gase absorbierende Getterstoff ist oder enthält dabei vorzugsweise Titan und/oder Aluminium und/oder Vanadium.The getter material which absorbs the harmful gases is or contains preferably titanium and / or aluminum and / or vanadium.
Der Getterstoff, welcher das Verhältnis der zum Betrieb der Lampe erwünschten Komponente der nicht edlen Gase aufrechterhält, ist zweckmäßig ein solcher oder enthält einen Bestandteil, der für Stickstoffnachschub sorgt, indem durch entsprechend hohe Erhitzung unter thermischer Zersetzung Stickstoff abgegeben wird.The getter substance, which is the ratio of the components required for operating the lamp to the non maintains noble gases, is expediently such or contains a component that is necessary for nitrogen replenishment ensures that nitrogen is given off through a correspondingly high level of heating with thermal decomposition.
Für diesen Zweck ist oder enthält der betreffende Getterstoff Bornitrid und/oder Zirkonnitrid und/oder Titannitrid. Neben Bornitrid, Titannitrid, Zirkonnitrid kann natürlich auch irgendein anderer ähnlicher Stoff verwendet werden.For this purpose, the relevant getter material is or contains boron nitride and / or zirconium nitride and / or Titanium nitride. In addition to boron nitride, titanium nitride, zirconium nitride, any other similar substance can of course also be used be used.

Die Fähigkeit des Titans, Wasserstoff zu absorbieren, zeigt im ganzen Temperaturgebiet zwischen der Zimmertemperatur und 300° C keine wesentlichen Unterschiede. Dies hat den Vorteil, daß man den Titangetter auch an kühleren Stellen der Lampe anordnen kann, wo das Titan Stickstoff praktisch kaum absorbiert. Gleichzeitig wird -die sauerstoffabsorbierende Fähigkeit auch an kühleren Stellen entsprechend sein, mit Rücksicht darauf, daß das Titan gegenüber dem Sauerstoff besonders empfindlich ist. Bei der Anwendung von Aluminium wird gemäß den Versuchsergebnissen die Absorption des Kohlenmonoxyds und der Kohlenwasserstoffe eine vorteilhaftere, wogegen "bei der Anwendung von Vanadium die Absorption bei mittleren Temperaturen einen vorteilhafteren Wert zeigt. Es ist daher beispielsweise vorteilhaft, Titan, Aluminium und Vanadium gemeinsam anzuwenden, wobei dann Titan in der größten Menge vorhanden ist. Titan kann jedoch auch allem angewendet werden. In bezug auf das Titan ist zu bemerken, daß man in die Lampe Titanhydrid einbringen kann, welches dann thermisch zu Titan zer- ao setzt wird.The ability of titanium to absorb hydrogen shows in the whole temperature range between room temperature and 300 ° C no significant differences. This has the advantage that you can also use the Titanium Setter Can arrange cooler places of the lamp, where the titanium hardly absorbs nitrogen. At the same time will -The oxygen-absorbing capacity must also be appropriate in cooler places, with consideration given to the fact that the Titanium is particularly sensitive to oxygen. When using aluminum, according to Experimental results show that the absorption of carbon monoxide and hydrocarbons is more advantageous, whereas "When using vanadium, the absorption at medium temperatures shows a more advantageous value. It is therefore advantageous, for example, to use titanium, aluminum and vanadium together, in which case titanium is present in the greatest quantity. However, titanium can also be applied to anything. In relation to titanium it should be noted that titanium hydride can be introduced into the lamp, which then thermally decomposes to titanium is set.
Zur Sicherung des Stickstoffnachschubs werden vorteilhaft ein oder mehrere der vorher erwähnten Nitride angewendet, welche, wie gesagt, im Laufe der thermischen Zersetzung N2 abgeben.To ensure the supply of nitrogen, one or more of the aforementioned nitrides are advantageously used, which, as stated, release N 2 in the course of thermal decomposition.
Werden z. B. Titan und Bornitrid gemeinsam verwendet, so kann eine Mischung dieser Stoffe an derselben Stelle der Lampe vorgesehen sein. In anderen Fällen, insbesondere wenn das Titan an im Verhältnis kühleren Stellen angeordnet wird, ist es vorteilhaft, das Bornitrid getrennt an einer wärmeren Stelle der Lampe anzuordnen. Unter Berücksichtigung der jeweiligen Verhältnisse kann man eine Mischung mehrerer der genannten Stoffe oder aber diese Stoffe einzeln getrennt mit Vorteil in der Lampe verwenden, wenn man diese in feinverteiltem Zustand entweder auf eine Metallfläche oder auf eine Glasfläche aufträgt.Are z. B. titanium and boron nitride are used together, a mixture of these substances can be used on the same Place of the lamp be provided. In other cases, especially when the titanium is relatively cooler Places is arranged, it is advantageous to arrange the boron nitride separately at a warmer place on the lamp. Taking into account the respective circumstances a mixture of several of the substances mentioned or these substances separately with advantage in the Use a lamp if you have it in a finely divided state either on a metal surface or on a glass surface applies.
Im Laufe der Versuche wurde auch die maximale Menge des notwendigen Getters festgestellt. Die Anwendung noch größerer Mengen kann für den Betrieb der Lampe in gewissen Fällen nachteilig sein. Es wurde gefunden, daß das Gewichtsverhältnis des absorbierenden Stoffes zum inneren Volumen der Lampe einen maximalen Wert dann erreicht, wennIn the course of the tests, the maximum amount of getter required was also determined. The application even larger amounts can be disadvantageous for the operation of the lamp in certain cases. It was found, that the weight ratio of the absorbent material to the internal volume of the lamp is a maximum Value reached when
E1^x = O1I-KE 1 ^ x = O 1 IK
ist, wo E'n:fäie zulässige größte Menge des Getterstoffes in mg und K das Volumen des Kolbens in cm3 bedeutet. Gleichzeitig wurde auch das richtige Gewichtsverhältnis des absorbierenden Stoffes im Verhältnis zu der in der Lampe vorhandenen Metallarmatur festgestellt, und es wurde gefunden, daß der maximale Wertis where E'n: fäie denotes the largest permissible amount of getter substance in mg and K denotes the volume of the flask in cm 3 . At the same time, the correct weight ratio of the absorbent material in relation to the metal armature present in the lamp was also determined, and it was found that the maximum value
E" — E " -
5555
ist, wobei E'nsx die notwendige maximale Menge des Getterstoffes in mg und G das Gewicht der Metallarmatur in g bedeutet., wherein E'n sx the maximum amount of getter necessary in mg and G is the weight in g of the metal fitting.
Schließlich sei noch bemerkt, daß es vorteilhaft ist, wenn die Temperatur der verschiedenen Getterstoffe im Innern der Lampe mindestens 150° C, jedoch höchstens 500° C beträgt. Es kann nämlich zwischen diesen Temperaturgrenzen erreicht werden, daß der Getter bzw. die Gettermischung keine schädliche Wirkung ausüben. Die vorstehenden Ausführungen beziehen sich auf Lampen mit Edelgasfüllung, bei welchen der Edelgasgehalt der Lampe mindestens 90 °/0 des gesamten Gasgehaltes beträgt.Finally, it should be noted that it is advantageous if the temperature of the various getter substances inside the lamp is at least 150.degree. C., but at most 500.degree. This is because it can be achieved between these temperature limits that the getter or the getter mixture have no harmful effect. The above statements relate to lamps with a noble gas filling, in which the noble gas content of the lamp is at least 90 ° / 0 of the total gas content.
