    Kühlvorrichtung   für Vakuummetalldampflampen. 



   Bei   Vakuummetalldampflampen   ist es bekannt, die erforderliche Wärmeableitung von den Polgefässen durch Grossoberflächenkühler (fächerartig   angeordnete Blechstüeke)   zu bewerkstelligen, die aussen an den Polgefässen befestigt sind. Die so ausgestatteten Vakuummetalldampflampen befinden sich innerhalb eines regelmässig aus Metall bestehenden Reflektors. Infolgedessen kann die   Grossoberfläehen-   kühlung der Polgefässe nur unvollkommen zur Wirkung gelangen, denn die   Grossoberflächenkühler   befinden sich in der fast unbewegten warmen Luft innerhalb des Reflektors. 



   Bei der neuen Kühlvorrichtung, die in einer Ausführungsform in der Fig. 1 in Vorderansicht, in der Fig. 2 im Längsschnitt und in der Fig. 3 in der Draufsicht schematisch dargestellt ist, befindet sich in der üblichen Weise die Vakuummetalldampflampe a innerhalb des Reflektors b, mit dem eine, ihre Polgefässe eng umschliessende Metallhülse c gut   wärmeleitend   verbunden ist. 



   In manchen Fällen ist es vorteilhaft, beispielsweise durch aussen an dem Reflektor angebrachte Kühlrippen d, den Reflektor als Grossoberflächenkühler auszubilden. 



   PATENT-ANSPRÜCHE :
1. Kühlvorrichtung zur Wärmeableitung von den Polgefässen von Vakuummetalldampflampen, dadurch gekennzeichnet, dass mindestens eine, die Pölgefässe eng   umschliessende   gut wärmeleitende Hülse gut wärmeleitend mit dem Reflektor verbunden ist.

    Cooling device for vacuum metal vapor lamps.



   In the case of vacuum metal vapor lamps, it is known to carry out the necessary heat dissipation from the pole vessels by means of large surface coolers (sheet metal pieces arranged in a fan-like manner) which are attached to the outside of the pole vessels. The vacuum metal vapor lamps equipped in this way are located within a reflector made of metal. As a result, the large-surface cooling of the polar vessels can only have an imperfect effect, because the large-surface coolers are located in the almost unmoved warm air inside the reflector.



   In the new cooling device, which is shown schematically in one embodiment in FIG. 1 in a front view, in FIG. 2 in longitudinal section and in FIG. 3 in plan view, the vacuum metal vapor lamp a is located within the reflector b in the usual manner , with which a metal sleeve c, which tightly encloses its pole vessels, is connected with good thermal conductivity.



   In some cases it is advantageous to design the reflector as a large surface cooler, for example by means of cooling fins d attached to the outside of the reflector.



   PATENT CLAIMS:
1. Cooling device for dissipating heat from the pole vessels of vacuum metal vapor lamps, characterized in that at least one, the pole vessels tightly enclosing well thermally conductive sleeve is connected to the reflector with good heat conductivity.
