Diagram of a Nernst lamp taken directly from an original instruction manual from 1903. [1]

Bildbeschreibung von Deglr6328: "A Nernst lamp diagram from 1903. It is interesting to note that the light emitting ceramic filament is called a "glower" as after Nernst lamps fell into obsolesence and disuse the term "Nernst glower" went on to be used to describe the infrared emitting source used in IR spectroscopy devices. Recently, even this term has become obsolete as Nernst glowers have been largely replaced for this purpose by silicon carbide glow bars or "globars" [2] which are conductive even at room temperature and therefore need no preheating."

Eigene Übers. (Bogart99 14:24, 14. Okt 2005 (CEST)): "Diagramm einer Nernstlampe von 1903. Interessanterweise wird der lichtemittierende Keramik-Heizfaden als "glower" (dt. "Leuchter") bezeichnet, denn nachdem Nernstlampen außer Gebrauch kamen wurde der Begriff "Nernst glower" weiterhin verwendet, um die Infrarot-emittierende Quelle bei IR-Spektroskopie-Geräten zu beschreiben. In jüngster Zeit veraltete auch dieser Begriff, weil "Nernstleuchter" weitgehend durch Siliziumkarbid-Leuchtstäbe bzw. "Globare" ersetzt wurden, die sogar bei Raumtemperatur leitend sind und deshalb nicht vorgeheizt werden müssen."
