Abstract

A discharge lamp lighting device comprising a drive circuit receiving an oscillation output of an oscillation circuit and generating a drive signal output; an oscillation circuit of the discharge lamp which is charged by the alternating ON/OFF of a plurality of switching elements of inverting bridge consisting of the drive signals thereby driving the discharge lamp; which is characterized in : comprising a current limiting circuit having an oscillation frequency for controlling the oscillation circuit thereby limiting the current flowing on the oscillation circuit; the current limiting circuit comprising a current detection circuit part for detecting the current flowing on the resonant circuit and converting the current into a voltage, and a frequency control circuit part for corresponding the output voltage of the current detection circuit part with the oscillation frequency of the oscillation circuit.
