Abstract

Beleuchtungssystem, umfassend eine quecksilberfreie Metallhalogenidlampe mit einer Lichtausbeute von mindestens 75 lm/W und einem Farbwiedergabeindex von mindestens 75 und ein elektronisches Vorschaltgerät, wobei das elektronisches Vorschaltgerät der Lampe eine Rechteck-Stromversorgung einprägt und die Leistung konstant hält. Die Füllung umfaßt folgende Komponenten:
  • ein Puffergas, das auch als Startgas zur Zündung der Lampe wirkt,
  • einen Spannungsgradientenbildner; bestehend aus mindestens einem Metallhalogenid, das leicht verdampft, und das hauptsächlich (zu mehr als 50%) dafür verantwortlich ist, einen Spannungsgradienten zu erzeugen, der in etwa dem von Quecksilber entspricht,
  • ein Lichterzeuger, bestehend aus einem Metall und/oder Metallhalogeniden.
