第(1)項記載の蛍光灯点灯装置。[Claims for Utility Model Registration] (1) An inverter circuit that rectifies an AC power source in a rectifier circuit and operates in oscillation by switching a switching element using the DC voltage smoothed in a smoothing circuit as a power source. A fluorescent lamp is connected to the circuit output, and a first switch for eliminating preheating current is connected to the non-power terminal of the fluorescent lamp, and a first switch for eliminating the resistance is connected in parallel with the resistor that prevents the input rush current that occurs when the power is turned on. In a fluorescent lamp lighting device with two switches connected, the first switch is turned on for a predetermined period of time from the moment AC power is supplied, the second switch is turned off, and the first switch is turned off after a predetermined period of time has elapsed. and a second switch is turned on. (2) The lighting of the fluorescent lamp according to claim 1, wherein the first switch and the second switch are configured by the contacts of the same relay, and the switch is provided with a control circuit for driving the relay. Device.
