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.

Lighting system comprising a mercury-free metal halide lamp with a luminous efficacy of at least 75 lm / W and a color rendering index of at least 75 and an electronic ballast, the electronic ballast impressing a rectangular power supply and keeping the power constant. The filling comprises the following components:
  • a buffer gas that also acts as a starting gas to ignite the lamp,
  • a voltage gradient generator; consisting of at least one metal halide, which evaporates easily and which is mainly (more than 50%) responsible for creating a voltage gradient which corresponds approximately to that of mercury,
  • a light generator consisting of a metal and / or metal halides.
