gebettet ist. Bei diesen Glühlampentypen wurde der Glühfaden zwischen zwei entsprechend geformten, massiven, sehr dicht aneinander anliegenden Stücken aus Glas oder dgl. luftdicht eingebettet, worauf die beiden Teile des Lampenkörpers durch einen Zement. durch eintauchen in geschmolzenes Glas oder in anderer geeigneter Weise fest und luftdicht miteinander vereinigt wurden.
Gemäss vorliegender Erfindung wird der massive Lampenkörper dadurch hergestellt, dass der mit einem entsprechenden luftdichten Material überzogene Glühfaden mit streng- flüssigem Glas von möglichst geringne Ausdehnungskoeffizienten oder reinem Quarz wiederholt überfangen wird, bis der Lampenkörper die gewünschte Stärke erreicht hat. hiebei werden gleichzeitig die Zuleitungsdrähte in die Lampe eingeschmolzen.

is bedded. In these types of incandescent lamps, the filament was embedded in airtight manner between two correspondingly shaped, solid, very tightly fitting pieces of glass or the like, whereupon the two parts of the lamp body were cemented. by immersion in molten glass or in some other suitable manner, firmly and airtightly combined.
According to the present invention, the massive lamp body is produced by repeatedly covering the filament coated with a corresponding airtight material with strictly liquid glass with the lowest possible expansion coefficient or pure quartz until the lamp body has reached the desired thickness. at the same time the lead wires are melted into the lamp.
