ABSTRACT:
A high frequency applicator for energizing electrodeless lamps is described. The applicators are end cups electrically attached to the ends of phased feed points of a planar transmission line, and facing each other so as to form a gap between the end cups. The end cups each have a concave surface facing the gap which forces an electric field concentration in the vicinity of the end cups and in the gap between the opposing end cups. Such a field configuration is useful for energizing a lamp capsule placed within the gaps formed by the end cups. The end cups can be made of metal or metallized ceramic.
