Definitions

  • an enlarged view of the electrode frame 1 is shown. It can be seen that in the tapered region 4, in which the glass bead 5 is formed drop-like, the two electrode holders 2 and 3 are arranged very close to each other.
  • the electrode frame is introduced into the discharge vessel such that the elongated strut is positioned outside the discharge vessel.
  • this arrangement can also be used to ensure accessibility to the transverse strut at any time. Even after the gas-tight fusing and in particular after squeezing the end region of the discharge vessel, into which the electrode frame extends into the discharge vessel, a handling of this elongate strut can be carried out.
  • the elongate strut is preferably completely separated from the electrode holders after the area-wise introduction of the electrode frame into the discharge vessel. This separation of the elongate strut preferably takes place after crushing of an end region of the discharge vessel for gastight sealing of the discharge vessel.
  • the oblong strut thus serves for the stabilization during the production and introduction of the electrode frame into the discharge vessel and can be removed, in particular after squeezing, after the electrode frame has been mechanically stably arranged anyway.
  • the elongate strut is separated prior to pumping the discharge vessel. Pumping means evacuating and filling the discharge vessel with a filling material.
  • the elongate strut is preferably at least 12 mm, in particular at least 15 mm, in particular at least 20 mm, spaced from the lamp filament attached to the electrode holders. By this spaced arrangement, a substantial shortening of the entire electrode frame can be achieved.
  • the elongate strut is formed as an electrically conductive element.
  • the elongate strut is a wire, in particular Another is a vacuum wire.
  • the electrode holders are made of such a wire, in particular a Vakuvit wire, and the elongate strut may be formed of a corresponding material.
  • the elongate strut is formed with such a length that, after attaching the strut to the electrode mounts, the distance between the two electrode mounts in the region of the attached strut substantially the distance of the two Elektrodenhalte- ments at the front end portions where the lamp filament attached is, corresponds.
  • a variety of bending and forming a tapered, bottle-like portion of the electrode holders, as required in the formation of a glass bead in the prior art, can be prevented thereby.
  • FIG. 4 shows an enlarged view of an inventive electrode frame in a further production step.
  • the elongated strut 8 is also formed in the embodiment of Vakuvit wire and has a diameter of about 0.4 mm, which also corresponds to the diameter of the two electrode holders 2 'and 3'.
  • the elongate strut 8 is introduced as a transverse strut between the two electrode holders 2 'and 3' and is attached to both electrode holders 2 'and 3'. attached by resistance welding.
  • the elongated strut 8 is arranged offset back to front end areas 21 and 31 of the electrode holders 2 'and 3'.
  • the distance d4 between these front end portions 21 and 31 of the E- lektrodenhalterept 2 'and 3' to the elongate strut 8 is about 15 mm.
  • the wires are planarized. Subsequently, hooks are then bent at the front ends 21 and 31, and subsequently the lamp filament 6 is inserted into these bent hooks and clamped there. Then an expansion dimension of the electrode holders 2 'and 3' is bent and the lamp filament 6 is pasted. Then follows a bending of the final dimension of the electrode frame 1 'and an insertion of this in the rack feed. In this state of manufacture, the electrode frame 1 'is in its basic condition completed. Subsequently, this electrode frame 1 'is then introduced into the discharge vessel 7. For this purpose, the front region, to which the lamp filament 6 is fastened, is introduced into the discharge space at an end region 71 of the discharge vessel 7. This follows in the embodiment so far that the elongate strut 8 is still outside the discharge vessel 7.
  • the electrode frame 1 ' is introduced into the discharge vessel 7 so far that a distance d5 between the lamp coil 6 and the lower edge region of the end region 71 is formed. This is in the exemplary embodiment about 10 mm and is thus substantially smaller, in particular by half smaller than the distance dl in the conventional embodiment according to FIG. 1.
  • the electrode frame 1 'must therefore be introduced far less into the discharge vessel 7, whereby the discharge space can be increased in comparison to the prior art.
  • the end region 71 is then heated and squeezed in the following so that the electrode holders 2 'and 3' are fixed in position in this end region 71. are squeezed and this end 71 is closed gas-tight.
