  • Fluorescent coating for high output lamps with color temperatures of less than 2700 kelvin
    Patent number: 8350460
    Abstract: The invention relates to a fluorescent coating for Hg low-pressure discharge lamps, comprising a fluorescent composition from at least one green fluorescent material emitting in the green spectral range, especially a Tb-and/or Eu-doped green fluorescent material, and a red fluorescent material emitting in the red spectral range, especially a Eu and/or Mn red fluorescent material. The invention is characterized in that a further fluorescent material is present which is adapted to absorb UV Hg and Hg-Vis radiation.
