Consisting of a high-voltage winding, a high-impedance element connected in series to the secondary high-voltage winding, and a switching element connected in parallel to this high-impedance element and becomes conductive after a predetermined period of time has passed after the power is turned on. A lighting device for a discharge lamp, characterized in that the discharge lamp is maintained in a slight discharge state or is inhibited from discharging until a predetermined time has elapsed after the power is turned on.

Claims

[Claims for Utility Model Registration] In a device comprising a discharge lamp connected to the secondary side of an inverter oscillation transformer operated by a power source obtained by rectifying an alternating current power source, the high voltage circuit for lighting the discharge lamp is provided as described above. A secondary high-voltage winding of the oscillation transformer, a high-impedance element connected in series to the secondary high-voltage winding, and a high-impedance element connected in parallel to the high-impedance element that becomes conductive after a predetermined period of time after power is turned on. It is composed of switching electrons,
A lighting device for a discharge lamp, characterized in that the initiation of discharge during the heating process of the discharge electrode of the discharge lamp is prevented by the high impedance element. '4 Figure 2-1
