Description

Verfahren zum Anbringen von Luminophoren auf die Glaswände von elektrischen Entladungsgefäßen, insbesondere elektrischen Entladungslampen Die Erfindung betrifft ein Verfahren zum Anbringen von Luminophoren auf die Glaswände von elektrischen Entladungsgefäßen, insbesondere el°ktrischen Entladungslampen oder diesen zugeordneten Glasschirmen 'oder Glashüllen, bei welchem auf die Glaswand vorerst eine Bindemittelschicht und auf diese sodann die Luminophorschicht aufgebracht wird.Method of attaching luminophores to the glass walls of electrical Discharge vessels, in particular electric discharge lamps The invention relates to a method of attaching luminophores to the glass walls of electrical Discharge vessels, in particular electrical discharge lamps or associated therewith Glass screens' or glass envelopes, in which a binder layer is initially applied to the glass wall and the luminophore layer is then applied to this.

Die Erfindung beruht in der Erkenntnis, daß .eine besonders gute Haftfähigkeit der Luminophorschicht ohne Beeinträchtigung der durch sie bewirkten Lichtumsetzung dann erhalten wird, wenn erfindungsgemäß als Bindemittel ,eine Arsensäureschichtoder Antimonsäureschicht verwendet: wird. Jede dieser beiden einander chemisch sehr nahestehenden Säuren bildet, wenn sie mit oder ohne Erwärmen zum Eintrocknen gebracht ist, zufolge chemischer Reaktion mit der Glassubstanz eine den Luminophor tragende zementartige Zwischenschicht, die eine große Haftfähigkeit der L umin:ophorschicht verbürgt. Hierbei ergibt sich des weiteren auch noch der zusätzliche Vorteil einer leichteren und sicheren Herstellungsweise des Luminophorbelages, da die genannten beiden Säuren im Gegensatz zu vielen anderen Säuren nicht hygroskopisch sind, daher keinen die Verarbeitung störenden Wasserdampf aus der Luft an sich reißen.The invention is based on the knowledge that .a particularly good adhesion the luminophore layer without impairing the light conversion caused by it is obtained when according to the invention as a binder, an arsenic acid layer or Antimonic acid layer used: is. Each of these two chemically very closely related Acids forms when dried with or without heating, according to chemical reaction with the glass substance creates a cement-like bearing for the luminophore Intermediate layer, which guarantees a high level of adhesion of the lumin: ophor layer. This also has the additional advantage of being lighter and safe production method of the luminophore coating, since the two acids mentioned unlike many other acids are not hygroscopic, hence none of them Processing disruptive water vapor from the air.
