Apparatus for lighting fluorescent lamp |
摘要 |
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 capacitor (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.
