PHOSPHOR COMPOSITION FOR LOW-PRESSURE GAS DISCHARGE LAMPS |
摘要 |
The phosphor composition for low-pressure gas discharge lamps with a high light efficiency for generating radiation with a color temperature of greater than 5000 K and a very good general color rendering index Ra of greater than 90 includes at least one halophosphate phosphor, a phosphor which emits in the red wavelength region and a phosphor which emits in the blue-green wavelength region. In addition, according to the invention the phosphor composition contains an Eu-doped barium magnesium aluminate phosphor BaMgAl10O17:Eu and a Tb-doped green-emitting phosphor.
