Abstract (en)
[origin: EP0453893A1] A mercury vapour high-pressure discharge lamp (1) having a metal halide filling contains a first rare earth halide (dysprosium, thulium, holmium) and a second rare earth halide (cerium, neodymium, praseodymium, lanthanum) and, finally, an alkali-metal halide (sodium, caesium). This filling eliminates, in particular, the red deficiency. <IMAGE>
