ABSTRACT:
An electrodeless high-intensity-discharge lamp, having an envelope situated within the bore of an excitation coil and in the interior of which envelope is to be provided a discharge plasma driven by the excitation coil, is provided with a pair of starting electrodes each of which is either adjacent to, or entering the envelope through, the associated one of an opposed pair of envelope end surfaces. Coupling of a high voltage pulse between the pair of starting electrodes causes an electric field to be produced, between each electrode and the other one of the electrodes or the excitation coil, of magnitude and position sufficient to cause the material within the lamp envelope to create at least one spark channel in which the plasma can then be formed responsive to the normal field provided by the excitation coil.
