A discharge lamp circuit in which the lamp is substantially instantaneously started and in which the power consumption of the lamp after starting is reduced with substantially no vibration due to piezoelectric effects and caused by currents flowing through a nonlinear dielectric element. An inductive stabilizer is connected in series with one of the filaments of the discharge lamp and a nonlinear circuit is connected in parallel with the filaments of the discharge lamp. The nonlinear circuit is composed of a nonlinear dielectric element and a bidirectional switching means connected in parallel with the nonlinear dielectric element. A reverse-conductive circuit is connected in series with the nonlinear circuit and in parallel with the filaments of the discharge lamp, the reverse-conductive circuit including a reverse-conductive semiconductor switch mean which is conduction-controlled in the forward direction but which is always conductive in the reverse direction. |
