ABSTRACT:
For coupling a halogen incandescent lamp to a plastic lamp base in correct positional relationship, a sheet-metal lamp holder is rigidly engaged with a hermetic end seal of the lamp, and a sheet-metal sleeve is anchored in the lamp base. The sleeve has several connecting fingers extending therefrom for somewhat loose engagement in openings in the lamp holder. The loose engagement of the sleeve fingers in the lamp holder openings permit adjustment of the positions of the lamp and the lamp base, which are secured respectively to the lamp holder and to the lamp base, with respect to each other. The sleeve fingers are welded to the lamp holder following the adjustment of the positional relationship between the lamp and the lamp holder.
