Claims
- 1. An apparatus for attaching a tab-type structure to the base of a high intensity discharge lamp, said apparatus comprising:
- a resistance welder; and
- a welding fixture attached to said welder including a frame, a bottom electrode disposed within said frame, having an apertured surface means for guiding said lamp within said apparatus in contact with said frame, a back stop structure having a surface positioned proximate to said guide means for minimizing lamp movement within said apparatus and a retractable top electrode positioned above and spaced from said bottom electrode;
- wherein said apertured surface of said bottom electrode supports said tab-type structure to be attached to said lamp base.
- 2. An apparatus for attaching a tab-type structure to the base of a high intensity discharge lamp, said apparatus comprising:
- a resistance welder; and
- a welding fixture attached to said welder including a frame, a bottom electrode disposed within said frame, having an apertured surface means for guiding said lamp within said apparatus in contact with said frame, a back stop structure having a surface positioned proximate to said guide means for minimizing lamp movement within said apparatus and a retractable top electrode positioned above and spaced from said bottom electrode;
- wherein said guide means includes two guide pins to guide said lamp within said fixture, said guide pin positioned on said frame on either side of said bottom electrode.
- 3. An apparatus for attaching a tab-type structure to the base of a high intensity discharge lamp, said apparatus comprising:
- a resistance welder;
- a welding fixture attached to said welder including a frame, a bottom electrode disposed within said frame, having an apertured surface means for guiding said lamp within said apparatus in contact with said frame, a back stop structure having a surface positioned proximate to said guide means for minimizing lamp movement within said apparatus and a retractable top electrode positioned above and spaced from said bottom electrode;
- a lamp support bracket spaced from said bottom electrode for supporting a lamp positioned within said apparatus; and
- a light source and screen, said light source disposed adjacent said welding fixture and emitting a light beam that passes through said lamp positioned within said fixture and creating a shadow image on said screen.
