zu geben. Ein Teil des Vorschaitwiderstandes kann den Kathoden gemeinsam sein.
Besonders vorteilhaft ist die neue Erfindung bei Anwendung von im wesentlichen plattenförmigen Anoden, die eine besondere Bedeutung für Projektionszwecke besitzen, weil die Lichtausstrahlung nach den Richtungen in denen sie nicht ausgenutzt werden kann. beschränkt ist. Sehr günstige Anordnungen

In der Zeichnung sind zwei Ausführungsformen der Erfindung dargestellt. und zwar zeigt Fig. 1 einen Längsschnitt und Fig. 2 je zur Hälfte den entsprechenden Grundriss und Querschnitt, und die Fig. 3 und 4 in Seiten-und Vorderansicht eine andere Anordnung der Kathoden. Die Fig. 5 und (i veranschaulichen schematisch die Einfügung der Vorschaltwiderstände in die Zuleitungen zu den Kathoden.

EMI1.2
to give. A part of the series resistor can be common to the cathodes.
The new invention is particularly advantageous when using essentially plate-shaped anodes which are of particular importance for projection purposes, because the light emission in the directions in which it cannot be used. is limited. Very favorable arrangements

of the edge, or if they are installed in this way, dat.! they are evenly distributed in the anode plane.
Two embodiments of the invention are shown in the drawing. 1 shows a longitudinal section and FIG. 2 shows half of the corresponding plan and cross section, and FIGS. 3 and 4 show a different arrangement of the cathodes in side and front views. FIGS. 5 and (i schematically illustrate the insertion of the ballast resistors into the leads to the cathodes.
EMI1.4
Ballast resistor is built in.
PATENT CLAIMS:
1. Tungsten arc lamp, characterized in that the anoder (a) is assigned several cathodes (b), for each of which a series resistor is provided.
