PROBLEM TO BE SOLVED : To provide a fluorescent lamp that can improve a lighting start characteristic by suppressing influence of the pressure, type and mixture ratio of gas enclosed in a tube.
SOLUTION : A fluorescent lamp 1 has a glass tube 10, a transparent conductive film 11, an auxiliary protection layer 12 and a phosphor layer 13. The transparent conductive film 11 is formed on the inner surface of the glass tube 10. The auxiliary protection layer 12 is formed of zinc oxide (ZnO) on the transparent conductive film 11 so that the particle size ranges from 0.010 to 0.035 μm and the specific surface area ranges from 40 to 50 m2/g. The phosphor layer 13 is formed of calcium halo-phosphate phosphor (Ca10 (PO4)3 FCl : Sb, Mn) and rare-earth phosphor on the auxiliary protection layer 12.
