Abstract

PURPOSE:To provide a discharge lamp lighting apparatus, in which an auxiliary starting electode is disposed adjacently of a main electrode, and the value of a resistance connected between said auxiliry starting electode and double-voltage starting circuit is selected in a proper range so as to effect transfer from auxiliary discharge to main discharge in a stable menner. CONSTITUTION:When terminal 1b of AC power source 1 is held at a positive voltage, capacitor 6 is charged at the polarity shown in the drawing. On the other hand, when terminal 1a of power source 1 is held at a positive voltage, a voltage charged in capacitor 6 and the voltage of power source 1 are impressed in series, so that capacitor 8 is charged to a double voltage. Output voltage of double-voltage starting circuit 5 is impressed between auxiliary electrode 4 and main electrode 3b via auxiliary starting resistance 10 and glow discharge is caused, whereby electrode 3b is heated and glow discharge is developed between main electrodes 3a and 3b. In the above arrangement, value of the auxiliary resistance 10 is 100-2000 ohm.
