Abstract
A high intensity discharge lamp includes 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 is a larger size than the legs. Electrical conductors extend through each of the legs and are spaced apart from each other in the discharge region. A light transmitting envelope encloses the arc tube. A frame member is electrically attached to one of the conductors. An ignition aid includes an electrically conductive foil disposed around one of the legs and in electrical contact with the frame member. An electrically conductive crown disposed in electrical contact with the foil is located on or near the central portion.
