PROBLEM TO BE SOLVED: To suppress effectively a falling amount of luminescence of a whole fluorescent light, deterioration of a luminosity distribution of the fluorescent light, reduction of the life of the fluorescent light, or the like. SOLUTION: It is a fluorescent lamp lighting circuit, equipped with a high frequency voltage generating circuit 11 which generates voltage for producing the fluorescent light 10 to be turned on, a current waveform detection circuit 12 which detects the current waveform of the voltage waveform from the current which flows to the turned-on fluorescent light 10, and a voltage control circuit 13 which controls generating of voltage, based on the result of the detection. |
