müssen, wie z. B. Wolfram-, Molybdän-oder Niekelmetall, also durchgehends kostspielige Metalle.
Wählt man die Anordnung nach vorliegender Erfindung, so lässt sich leicht die Menge des'in Betracht kommenden Stromzuführungsmetalles auf einen Bruchteil vermindern. Ba ist sogar unter Umständen möglich, statt der teueren Metalle billigere Metalle zu verwenden, die bei anderer Anordnung überhaupt nicht in Betracht gezogen werden könnten.
In der Zeichnung sind zwei Ausführungsformen dargestellt.
Fig. 1 zeigt einen ringförmigen Gliihkörper der bisher üblichen Anordnung. Die Stromzuführungen sind bis dicht an die Spirale herangeführt.
Fig. 2 zeigt eine Anordnung gemäss vorliegender Erfindung. Die Spirale a ist an ihren Enden bund c gestreckt und nach den Stromzuführungen hin abgebogen. Die abgebogenen Stücke d und e sind so lang, dass sie einer bedeutenden Abkühlung durch das Gas in der Lampenglocke unterliegen und die Nachteile der Lichtbogenbildung in der Nähe der Anschlussstelle vermieden werden ; f und g sind die Stromzuführungen.
Während bei der üblichen Anordnung, wie sie in Fig, 1 dargestellt ist, die Halterung nur durch die Halter h, i, k geschieht und in der Nähe des Endes der Spirale keine besondere Halterung erforderlich ist, ist es bei vorliegender Anordnung zweckmässig, an den Enden der
Spirale noch je einen Halter/bzw. m anzubringen.
Fig. 3 zeigt eine Anordnung nach vorliegender Erfindung mit zickzackförmigem Spiraldraht.

can therefore reduce the strength of this power supply to the mechanically permissible limits.

must, such as B. tungsten, molybdenum or Niekelmetall, so consistently expensive metals.
If the arrangement according to the present invention is selected, the amount of the power supply metal in question can easily be reduced to a fraction. Ba is even possible under certain circumstances to use cheaper metals instead of the expensive metals which could not be considered at all in a different arrangement.
Two embodiments are shown in the drawing.
Fig. 1 shows an annular glow body of the conventional arrangement. The power supply lines are brought right up to the spiral.
Fig. 2 shows an arrangement according to the present invention. The spiral a is stretched at its ends b and c and bent towards the power supply lines. The bent pieces d and e are so long that they are subject to significant cooling by the gas in the lamp cap and the disadvantages of arcing near the connection point are avoided; f and g are the power supply lines.
While in the usual arrangement, as shown in Fig. 1, the holder is only done by the holder h, i, k and no special holder is required near the end of the spiral, it is useful in the present arrangement to the Ends of
Spiral still one holder / or. m to be attached.
Fig. 3 shows an arrangement according to the present invention with a zigzag spiral wire.
