Abstract

Die Erfindung betrifft eine Anordnung mit einer Gasentladungslampe (10),

  • mit einer ersten mit der Gasentladungslampe (10) in Reihe geschalteten Drossel (26), welche dazu ausgebildet ist, den Strom (iL) durch die Gasentladungslampe (10) auf einen ersten Strom (Fig. 7) zu begrenzen,
  • welcher einer hohen Leistung der Gasentladungslampe (10) entspricht,
  • mit einer zweiten, mit der Gasentladungslampe (10) in Reihe geschalteten Drossel (28), welche dazu ausgebildet ist, in Verbindung mit der ersten Drossel (26) den Strom (iL) durch die Gasentladungslampe (10) auf einen zweiten Strom (Fig. 6) zu begrenzen, der einer niedrigen Leistung der Gasentladungslampe (10) entspricht,
  • und mit einem steuerbaren Halbleiter-Leistungssteller (30), welcher zur zweiten Drossel (28) parallelgeschaltet ist und im eingeschalteten Zustand,
  • abhängig von dem an ihm eingestellten Strom, einen Strom (ith) über diesen Halbleiter-Leistungssteller (30) an der zweiten Drossel (28) vorbeifließen lässt und dadurch eine Einstellung des Stroms (iL) durch die Gasentladungslampe (10) im Bereich zwischen erstem und zweitem Strom ermöglicht.

    The invention relates to an arrangement with a gas discharge lamp (10),
  • with a first choke (26) connected in series with the gas discharge lamp (10), which is designed to limit the current (i L ) through the gas discharge lamp (10) to a first current (FIG. 7),
  • which corresponds to a high output of the gas discharge lamp (10),
  • with a second inductor (28) connected in series with the gas discharge lamp (10), which is designed to connect the current (i L ) through the gas discharge lamp (10) to a second current (Fig 6) limit, which corresponds to a low power of the gas discharge lamp (10),
  • and with a controllable semiconductor power controller (30) which is connected in parallel with the second choke (28) and in the switched-on state,
  • depending on the current set on it, a current (i th ) flows past this second power chopper (30) past the second choke (28) and thereby an adjustment of the current (i L ) through the gas discharge lamp (10) in the range between first and second stream enabled.
