Discharge lamp device for reducing noise radiation and surge pulse current

A discharge lamp device comprising:

• a lighting control circuit device including:
• a DC/DC conversion circuit having a first transformer for boosting a direct current voltage from a direct current power source;
• an inverter circuit having a semiconductor switching device for converting the voltage boosted by said DC/DC conversion circuit into an alternating current voltage;
• a starting circuit having a second transformer for boosting to a voltage which causes a breakdown between electrodes of a discharge lamp in starting up said discharge lamp;
• and
• an electronic circuit case for accommodating said DC/DC conversion circuit, said inverter circuit, and said starting circuit, the discharge lamp device further comprising:
• a secondary winding of said second transformer of said starting circuit that is connected between said discharge lamp and said inverter circuit connected to said discharge lamp, and
• an electrode member interposed between said second transformer and said electronic circuit case.
