FLUORESCENT COMPOSITION FOR A LOW-PRESSURE DISCHARGE LAMP HAVING A VERY HIGH COLOR TEMPERATURE |
摘要 |
A phosphor composition for a low-pressure discharge lamp with a high light yield and a high color temperature contains phosphors which emit in the red wavelength region, including yttrium oxide doped with europium or gadolinium-zinc-magnesium pentaborate doped with cerium and manganese, phosphors which emit in the green wavelength region including lanthanum phosphate doped with cerium and terbium and/or cerium-magnesium aluminate doped with terbium and/or cerium-magnesium pentaborate doped with terbium, and optionally a phosphor which emits in the blue wavelength region of the barium-magnesium aluminate doped with europium type. The phosphor composition additionally contains at least one phosphor which emits in the blue or blue-green wavelength region selected from the group consisting of manganese-strontium-barium-magnesium aluminate doped with manganese and europium or barium-magnesium aluminate doped with europium and manganese and strontium aluminate doped with europium and strontium-barium-calcium chloroapatite doped with europium and strontium borophosphate doped with europium. |
