Abstract
The invention proposes a dielectric barrier discharge lamp having a phosphor mixture and improved color rendering. The phosphor mixture comprises at least the phosphor components A: cerium-activated yttrium aluminate (YAlO:Ce) and B: europium-activated barium magnesium aluminate (BaMgAlO:Eu). To further improve the color rendering and to match the emission spectrum to the spectral sensitivity of film, the phosphor mixture optionally also comprises the phosphor component C: cerium- and manganese-activated gadolinium magnesium zinc pentaborate (Gd(Zn,Mg)BO:(Ce, Mn)) and/or the phosphor component D: europium-activated strontium aluminate (SrAlO:Eu).
