ABSTRACT:
A high-pressure discharge lamp provided with an outer bulb enclosing a discharge tube accommodates a transformer having primary winding which forms part of a current conductor to one of the main electrodes of the discharge tube. The secondary winding is coupled to an ignition electrode of the discharge tube. Higher ignition voltages can be achieved without increasing the voltage pulse on the outside contacts of the lamp.
