  Verfahren zur Bindung der Restgase in   elektrischen   Glühlampen. 
 EMI1.1 
 diese Substanz auf die beim Brennen verhältnismässig schwächer erwärmten Teile der Lampe, wie beispielsweise auf den Glasstab oder die Linsen u. dgl. mehr, gegeben hat, also auf Stellen, welche Temperaturen aufwiesen, bei welchen eine Zersetzung der Verbindung innerhalb der beim   Klarbrennen   in Betracht kommenden Zeiten und daher eine Bindung der Restgase durch den erst auf dem Wege der Zersetzung entstehenden Phosphor nicht erfolgen kann. 



   Unterschiedlich hievon wird erfindungsgemäss so verfahren, dass die Phosphor-StickstoffVerbindung auf die heissen Teile der Lampe aufgetragen wird. 

 <Desc/Clms Page number 2> 

 



   Es war ferner bereits   bekannt, Phospham P"N2H   am Leuchtdraht anzubringen, jedoch gibt   Phosphanm   bei der Zersetzung eine sehr erhebliche Gasmenge frei, zu deren Bindung besondere Gettersubstanzen notwendig wären, überdies aber eine erhebliche Menge Wasserstoff, welcher mit Resten von Sauerstoff Wasserdampf bildet, der den Faden   schädigt.   Im Gegensatz hiezu werden erfindungsgemäss nur wasserstofffreie Phosphorverbindungen verwendet. Auch ist die bei der Zersetzung des vorzugsweise verwendeten Phosphor-Stickstoffs entstehende Gasmenge bedeutend geringer und jedenfalls nicht so gross, dass zu ihrer Bindung eine besondere Gettersubstanz notwendig wäre. 



   Unter den   Sehutzbereich   vorliegender Anmeldung sollen aber auch   Ausführungsformen   fallen. bei welchen die anmeldungsgemässen Substanzen in Kombination mit andern, an sich bekannten Gasbindemitteln oder in Kombination mit Entsehwärzungsmitteln oder   Troekenmitteln   od. dgl. mehr verwendet werden. Die Erfindung ist offenbar zahlreicher Ausgestaltungen fähig und soll nicht auf das   Ausführungsbeispiel     eingeschränkt   verstanden werden. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Bindung der Restgase in elektrischen   Glühlampen,   dadurch gekennzeichnet, dass auf den Leuchtdraht und eventuell auch auf die denselben tragenden Teile eine wasserstoffreie Phosphorverbindung aufgebracht wird, welche erst in der Glühlampe durch Erhitzen des   Leuchtdrahtes   Phosphor freigibt.

  Process for binding residual gases in electric light bulbs.
 EMI1.1
 this substance on the parts of the lamp that are relatively less heated when burning, such as on the glass rod or the lenses and the like. Like. More, has given, that is, to places which had temperatures at which a decomposition of the compound within the times considered in the clear firing and therefore a binding of the residual gases by the phosphorus only formed during the decomposition cannot take place.



   In contrast to this, the procedure according to the invention is such that the phosphorus-nitrogen compound is applied to the hot parts of the lamp.

 <Desc / Clms Page number 2>

 



   It was also already known to attach Phospham P "N2H to the light wire, but when it decomposes, Phosphanm releases a very considerable amount of gas, which would require special getter substances to bind it, but also a considerable amount of hydrogen, which forms water vapor with residues of oxygen In contrast to this, only hydrogen-free phosphorus compounds are used according to the invention. Also, the amount of gas produced during the decomposition of the phosphorus-nitrogen, which is preferably used, is significantly less and in any case not so great that a special getter substance would be necessary to bind it.



   However, embodiments are also intended to fall under the scope of the present application. in which the substances according to the application are used in combination with other gas binding agents known per se or in combination with softening agents or drying agents or the like. The invention is obviously capable of numerous configurations and should not be understood as being restricted to the exemplary embodiment.



   PATENT CLAIMS:
1. A method for binding the residual gases in electric incandescent lamps, characterized in that a hydrogen-free phosphorus compound is applied to the light wire and possibly also to the same supporting parts, which phosphorus is only released in the incandescent lamp by heating the light wire.
