Abstract

Eine quecksilberfreie Metallhalogenidlampe mit einer Lichtausbeute von mindestens 70 lm/W und einem Farbwiedergabeindex von mindestens 80, besitzt ein keramisches Entladungsgefäß, in das Elektroden vakuumdicht eingeführt sind. Die Füllung umfaßt folgende Komponenten:

  • ein Edelgas, das als Puffergas wirkt,
  • eine Verbindung eines Halogens X mit zumindest einem der Metalle Hafnium und/oder Zirkon (im folgenden als Metallhalogenid HZM bezeichnet), wobei dieses Halogenid im folgenden zusammenfassend als HZH bezeichnet wird, wobei HZH gleichzeitig Aufgaben der Spannungsgradientenbildung und der Förderung des Kreisprozesses wahrnimmt,
  • ein Lichterzeuger, bestehend zumindest aus einem weiteren Metallhalogenid,
  • mindestens ein weiteres Metallhalogenid MYn, das leicht verdampft und das als Spannungsgradientenbildner verwendet wird,
  • wobei der spezifische Mol-Gehalt der HZH größer gleich 3 µmol/cm3 ist.
A mercury-free metal halide lamp with a light output of at least 70 lm / W and a color rendering index of at least 80, has a ceramic discharge vessel, in which electrodes are inserted vacuum-tight. The filling comprises the following components:
  • a noble gas that acts as a buffer gas,
  • a compound of a halogen X with at least one of the metals hafnium and / or zirconium (hereinafter referred to as metal halide HZM), this halide being referred to collectively as HZH, wherein HZH simultaneously performs tasks of stress gradient formation and promotion of the cyclic process,
  • a light generator, consisting of at least one additional metal halide,
  • at least one further metal halide MY n , which readily evaporates and which is used as a stress gradient former,
  • wherein the specific molar content of the HZH is greater than or equal to 3 μmol / cm 3 .

Dabei gilt zusätzlich: 5≤(X+Y)/HZM≤15, wodurch die Lebensdauer der Lampe mehr als 5000 Std. beträgt.
