Description

  

      Z-usatzpatent    zum Hauptpatent     Nr.    192442.    Elektrische     Lainpe.       Gegenstand vorliegender Erfindung ist  eine elektrische Lampe gemäss dem Patent  anspruch des Hauptpatentes mit einer     Ver-          dampfungsleuchtröhre    und einem zu dieser  parallel geschalteten Glühfaden. Die zusätz  liche Erfindung besteht darin,     dass    die     Ver-          dampfungsleuchtröhre    von     Zündgasen    frei ist.  



  Die bisher verwendeten     Verdampfungs-          leuchtröhren    benötigten zur Einleitung der  Zündung und Herabsetzung der Zündspan.       nung    spezielle Gase, vorzugsweise Edelgase,  wie z. B. Argon und Neon. Diese Gase waren  dazu da, die Entladungsstrecke für eine ent  sprechende Zündspannung leitfähig zu ge  stalten, weil der durch die     Gasentladungs-          temperatur    erzeugte Dampf des     Metallboden-          körpers    ja erst leitfähig wird, wenn er den  entsprechenden Sättigungsdruck erreicht hat.  Dieser wiederum kann nur erreicht werden,  wenn das Rohr die dafür notwendige Tem  peratur besitzt.  



  Diese kostspielige und langwierige<B>Ab-</B>  füllung von Edelgasen ist bei der erfindungs  gemässen Röhre überflüssig, weil der in Pa  rallelschaltung zu dieser     Verdampfungsleucht-          röhre    liegende Glühfaden eine solche Wärme    ausstrahlt,     dass    der     Metallbodenkörper,    wie  z. B.     Rg,    Na, sofort so verdampft wird,     dass     bereits zur Zündung die Leitfähigkeit der  Röhre über die Moleküle des Metalldampfes  hergestellt wird.

   Es genügt also bei der 'er  findungsgemässen Lampe, das Rohr nur zu  evakuieren und den Bodenkörper einzubrin  gen.     Zweckmässigerweise    besitzt<B>-</B> dabei die       Verdampfungsleuchtröhre    ausser dem     ver-          dampfbaren        Metallbodenkörper    keine weitere  Füllung.



      Additional patent to main patent no. 192442. Electric Lainpe. The present invention relates to an electric lamp according to the patent claim of the main patent with an evaporation tube and a filament connected in parallel to this. The additional invention is that the evaporation tube is free of ignition gases.



  The previously used evaporation tubes were required to initiate the ignition and reduce the ignition voltage. tion special gases, preferably noble gases, such as. B. argon and neon. These gases were there to make the discharge path conductive for a corresponding ignition voltage, because the vapor of the metal floor body generated by the gas discharge temperature only becomes conductive when it has reached the corresponding saturation pressure. This, in turn, can only be achieved if the pipe has the required temperature.



  This costly and lengthy <B> Ab- </B> filling of noble gases is superfluous with the tube according to the invention, because the filament in parallel to this evaporation tube radiates such heat that the metal bottom body, such. B. Rg, Na, is immediately evaporated in such a way that the conductivity of the tube is established via the molecules of the metal vapor at the time of ignition.

   In the case of the lamp according to the invention, it is therefore sufficient only to evacuate the tube and to bring in the bottom body. Expediently, the evaporation tube has no further filling apart from the vaporizable metal bottom body.
