HIGH INTENSITY DISCHARGE LAMP WITH IGNITION AID.

摘要

A high intensity discharge lamp 10 includes an electrically insulating arc tube 14. A sealed shroud 12 encloses the arc tube. An electrically conductive frame member 18 is disposed inside the shroud and is electrically connected to an electrical conductor 30 that extends in the arc tube. Electrically conductive foil 26 is fastened to the frame member and forms a closed loop that encircles a leg 42 of the arc tube by an angle in a range of at least 270 degrees to 360 degrees. The foil is fastened to the frame member and can be connected to it¬ self. A distance from an outer surface of a flange of the arc tube leg to a proximal edge of the foil can range from 1.5 to 8 mm. A width of the foil can range from 1 mm to 4 mm.
