Definitions

  • a metal halide lamp with a wall load of more than 40 W / cm 2 is known, in which a filling is introduced in a discharge vessel with activated electrodes, which contains either aluminum chloride or bromide.
  • Such fillings tend to have very short lifetimes in the order of 100 hours. They should produce a spectrum similar to daylight, with a high load being accepted.
  • EP-A 459 786 a lamp for photo-optical purposes and a long service life is known, in particular for video projection, which contains mercury and argon as filling components iodides of the rare earths dysprosium and neodymium as well as cesium.
  • Rare earth fillings have hitherto been customary for lamps of this type, since they ensure good color rendering with high luminous efficacy. We hereby expressly refer to the content of this document.
  • a bulb made of ceramic material (Al 2 O 3 ) is also suitable, as is already known for other lamp types.
  • the lamp is advantageously combined with a reflector to form a structural unit, as described in EP-A 459 786.
  • the lamp is mounted approximately axially in the reflector.
  • the reflector has a dichroic coating, for example.
  • 0.05 mg Tm is added to the first embodiment. This achieves an R / G / B ratio of 26.5: 57.5: 16.
  • the corresponding spectrum is shown in FIG. 8. There, the spectrum without Tm (curve a) from FIG. 2 is compared with that of the Tm-containing filling (curve b).
  • the thulium mainly fills the spectrum between 510 and 630 nm.
  • FIG. 6 and 7 show the behavior of a 200 W lamp, which is otherwise constructed similarly to the 170 W lamp.
  • the fillings used here are on the one hand identical to filling C), and on the other hand the following filling E) was used: E) 0.9 mg AlJ 3 , 0.1 mg InJ, 0.36 mg HgBr 2 .
