PROBLEM TO BE SOLVED: To provide a fluorescent lamp inverter circuit which reduces heat generation of a fluorescent lamp tube itself by preventing an effective value of lighting current from fluctuating even if an input voltage of the fluorescent lamp inverter circuit fluctuates and prevents the precision of dimmer light control from worsening. SOLUTION: This fluorescent lamp inverter circuit has input voltage detection means R11, R12 detecting voltages input in an inverter IN which supplies power to a fluorescent lamp 2, a signal generation means 7 generating a signal which lights the fluorescent lamp 2, and a frequency adjusting means Tr11 changing a frequency of a signal generated by the signal generation means 7 in accordance with a voltage value detected by the input voltage detection means R11, R12. |
