ABSTRACT:
A pair of starting electrodes are provided for an electrodeless high-intensity-discharge lamp of the type having an arc tube situated within the bore of an excitation coil and in the interior of which tube is to be provided a plasma arc discharge driven by the excitation coil. Each of the starting electrodes is a conductive ring actuated by a piezoelectric bender to move from a normal rest position away from the arc tube to a starting portion disposed adjacent to an associated one of an opposed pair of envelope surfaces. A high-voltage pulse coupled between the starting electrodes causes an electric field to be produced sufficient to create a glow discharge in the arc tube, and cause an almost instantaneous transition to a high-current solenoidal discharge to form the discharge plasma responsive to the normal field provided by the excitation coil; thereafter, the benders are de-activated and the starting electrodes move back to the rest positions.
