A self-excited oscillation type inverter that converts a DC voltage into a high-frequency voltage and lights a low-pressure discharge lamp through the current-limiting impedance of a capacitive reactance.It is installed on the output side of this inverter and generates a discharge current to the discharge lamp when cut off. and a control device that shuts off the switch device during a period including near the center of each half-cycle of the output current of the inverter when the discharge lamp is lit, The control device includes a monostable multi-by-break having a re-trigger function that generates a period for cutting off the switch device, and when the discharge lamp is not lit, the re-trigger puts the switch device in the cut-off state. A discharge lamp lighting device characterized by having a configuration that maintains the discharge lamp.
