Abstract
An electrodeless lamp assembly includes an electrodeless, high intensity discharge lamp capsule and a coaxial electric field applicator. The coaxial electric field applicator includes an outer conductor assembly including a tubular outer conductor having a distal end disposed at or near a first end of the lamp capsule, an outer ring disposed at or near a second end of the lamp capsule, and a plurality of cage wires connected between the outer ring and the tubular outer conductor. A center conductor assembly includes a center conductor coaxially positioned with respect to the tubular outer conductor and has a distal end disposed at or near the first end of the lamp capsule. High frequency power, supplied to the tubular outer conductor and the center conductor, is coupled by the electric field applicator to the lamp capsule. The center conductor assembly may include a guard ring positioned near the first end of the lamp capsule for concentrating electric fields in the lamp capsule.
