Conductive Layer Net Ignition Aids

Abstract

Embodiments of the present invention relate to high intensity discharge (“HID”) lamps which have an electrically insulating arc tube including a central portion with an interior discharge region and two legs each extending from an end of the central portion, the central portion being a larger size than the legs. Electrical conductors extend through each of the legs and are ending in electrode components which are spaced apart from each other in the discharge region. A light transmitting envelope encloses the arc tube, and a frame member is electrically attached to one of the electrical conductors. Pursuant to some embodiments, an ignition aid is provided which includes an electrically conductive element disposed on one of the legs. The ignition aid includes a conductive layer that extends from the electrically conductive element to the central portion.
