Abstract: <P>PROBLEM TO BE SOLVED: To provide a discharge lamp lighting circuit capable of suppressing increase of a current volume flowing in each of elements composing a chopper circuit even if a value of an input power source voltage to the chopper circuit decreases and capable of preventing increase of a heating volume of each of the elements.  <P>SOLUTION: In the discharge lamp lighting circuit 1, if a value of an input power source voltage decreases to less than 100V (for example, a 90V of an effective voltage), a current volume of a tube current decreases by the decreased value of the input power source voltage. Therefore, even if the value of the input power source voltage decreases to less that 100V, the current volume of the tube current decreases by the same amount and resultantly an increase of the current volume flowing in each of the elements (a chopper switch element Tr1 or a diode D5 or the like) composing a step-up chopper circuit 20 can be suppressed. Therefore, according to the discharge lamp lighting circuit 1 of this embodiment, even if the input power source voltage decreases to less than 100V, the increase of the heating volume of each of the elements composing the step-up chopper circuit 20 can be prevented.  <P>COPYRIGHT: (C)2011,JPO&INPIT
