FLUORESCENT MERCURY VAPOR DISCHARGE LAMP COMPRISING TRICHROMATIC PHOSPHOR BLEND

摘要

A fluorescent mercury vapor discharge lamp for generating white light with good color rendering of illuminated objects is achieved by blending three different phosphors, namely a blue green-emitting phosphor Ba_1-a-bM_gA1₁₀O₁₇:Eu_aMn_b, wherein 0.01 = a = 0.5 and 0 = b = 0.5, a yellow-emitting phosphor selected from the group of (Sr_{1 -}
