Abstract
PURPOSE: To set the color face frequency (CFF) below 45Hz without sacrificing the color tone of blue color fluorescent face, by forming the fluorescent face while employing the mixture of silver activated zinc sulfide fluorecent material and green fluorescent material having long time after-glow as blue light emitting material, while setting the color level of said blue color fluorescent face in specific range.
CONSTITUTION: Zn3(PO4)2: Mn, MgSiO3: Mn or mixture of them is employed as red fluorescent material. While Zn2SiO4: Mn, Zn2SiO4: Mn, As or the mixture of them is employed as green fluorescent material. Silver activated zinc sulfide ZnS: Ag mixed with said green fluorescent material is employed as blue fluorescent material, where the color level (CIE color indicating system) on blue fluorescent face is set such that 0.140≤x≤0.165, 0.05≤y≤0.08. Consequently color face frequency (CFF) can be set below 45Hz without sacrificing the color tone on blue fluorescent face.
