| titleOfInvention | SPIRAL STARTING ELECTRODE FOR HIGH INTENSITY DISCHARGE LAMPS |
| abstract | A firing electrode 20 is provided for a high intensity discharge lamp 10, free of electrodes, of the type having a tube 11 located inside the bore of an excitation coil 16, in which tube a plasma discharge must be produced which is caused by the excitation coil. The initiating electrode is a conical conductive coil having a narrow end 20e disposed adjacent to the surface of the tube. A high voltage is developed by induction, while the spiral electrode receives an HF magnetic flux, to cause a sufficient electric field to create a glow discharge in the tube, and cause there to be a rapid passage through a high intensity solenodal discharge to form the discharge plasma in response to the normal field provided by the excitation coil. Application to high intensity discharge lamps, devoid of electrodes. |
