れる効果を有する。As described above, according to the present invention, at least one preheating winding is attached to the output winding of the output transformer of the high frequency inverter! It is connected differentially, and the voltage between both electrodes of the discharge lamp is set to below the starting voltage before the filament preheating is completed when the power is turned on, and above the starting voltage after the preheating is completed, and glow discharge is automatically performed after the preheating is completed. This eliminates the drawback of the conventional method, which applies a voltage higher than the starting voltage at that point between the electrodes of the discharge lamp before the preheating is completed, that is, shortens the service life due to damage to the filament4. It has the effect of eliminating it.

実に行なえる効果を有するＯFurther, according to the present invention, a switch means is inserted in a preheating circuit constituted by a filament and a preheating winding differentially connected to an output winding, and the preheating circuit is opened by the switch means after preheating of the filament is completed. Therefore, even if for some reason the lamp voltage of the discharge lamp drops below its starting voltage when preheating is completed, the preheating circuit will be opened immediately after that.
The lamp voltage of the discharge lamp can be made higher than the starting voltage before the preheating of the filament is completed, and the discharge lamp can be lit reliably.
