  • Discharge lamp lighting apparatus including a sintered type oxide negative resistance starting element
    Patent number: 3991340
    Abstract: A discharge lamp (e.g., fluorescent lamp) lighting apparatus using as the starting element a sintered type oxide resistance element having the voltage-current characteristic that the element is rendered conductive when impressed with an inter-electrode voltage applied at the discharge lamp starting time and rendered substantially non-conductive while impressed with an inter-electrode voltage applied during lighting of the discharge lamp. The discharge lamp lighting apparatus using in particular a sintered type oxide resistance element comprising ZnO, MgO and MnO.sub.2 as the starting element presents an excellent performance.
