置。 A hot cathode with dimming includes a hot cathode fluorescent tube in which a self-excited inverter that supplies DC power to the power terminal is connected to a filament electrode, and the dimming of the hot cathode fluorescent tube is controlled by a dimming control generation circuit. In the fluorescent tube lighting device, the self-excited inverter has a transformer, and the secondary output of the transformer is connected to both poles of one side of the filament of the hot cathode fluorescent tube through a capacitor, and the secondary output of the transformer is The configuration is such that the rectified output of the self-excited inverter is guided through a rectifier circuit, and both poles of one side of the filament of the hot cathode fluorescent tube are connected to receive adjustment from the dimming control signal generation circuit. 1. A dimming hot cathode fluorescent tube illumination device comprising a switch circuit that controls the brightness of the hot cathode fluorescent tube using a switch mechanism that opens and closes in response to a light control signal.
