摘要
A high intensity discharge lamp, such as a high power sodium or metal halide lamp, having an electronic ballast. The electronic ballast may incorporate resonance-based circuitry for achieving an ignition state via a frequency sweeping step, the particular ignition voltage being inherent to the operational state of the high intensity discharge lamp. The operating state of the lamp may be sensed in order to apply power and voltage levels appropriate for steady state operation.
