A fluorescent lamp lighting apparatus in accordance with the present
invention has first switching means (M1) driven by a high-voltage-side
pulse signal input from a drive-signal generation circuit and second
switching means (M2) driven by a low-voltage-side pulse signal input from
the drive-signal generation circuit, wherein the first switching means
(M1) is connected in series with the second switching means (M2), and a
first capacity (C5) and an inductance element (L1) and the
above-mentioned second switching means (M2) are provided between the
high-voltage-side terminals of a pair of filament electrodes of a
light-emitting tube (4), whereby a constant luminous flux can be
maintained immediately after lighting.
