摘要：
Tips (34) for electrodes that are adapted to be applied to a ceramic halide lamp are formed by backwinding tungsten wire into a coil (42) onto a tungsten shank (40). The outer diameter (D3) of the coil of tungsten wire is maintained sufficiently small so that the electrode tips can be inserted through openings in the legs of the electric arc tube of the ceramic halide lamp and the tungsten coil (42) positioned within the hollow interior of the electric arc tube.
