ランプ点灯装置。[Claim for Utility Model Registration] A DC power supply circuit that full-wave rectifies a commercial AC power supply using a full-wave rectifier circuit, smoothes it with a smoothing capacitor, and converts it to DC, and a DC power supply circuit that generates fluorescence by driving oscillation by applying DC voltage. In a fluorescent lamp lighting device equipped with an inverter circuit that lights the lamp at high frequency, there is a resistor that is connected between the smoothing capacitors of the full-wave rectifier circuit of the DC power supply circuit to prevent rush current when the commercial AC power is turned on, and this resistor. A normally open relay contact connected in parallel to the AC power source, and a relay that operates after a delay time of half a cycle or more of the commercial AC power source and closes the relay contact with the AC current flowing from the time the commercial AC power source is turned on. Fluorescent lamp lighting device.
