  • Electric incandescent lamp
    Patent number: 4404491
    Abstract: In some types of electric incandescent lamps a cylindrical contact cap is connected to the part of the current supply conductor projecting beyond the pinch seal of the lamp envelope, which cap is mounted in an insulator sleeve. In known lamps the ceramic insulator sleeve 9 is secured on the pinch seal by means of cement.In lamps according to the invention, the insulator sleeve is coupled to the contact cap by means of a metal spring.

  • Halogen incandescent lamp
    Patent number: 4396858
    Abstract: A two-pinch line voltage halogen incandescent lamps according to the invention has metal foils in the pinches which foils are connected to respective internal current conductors and external conductors. The metal foils extend from the pinches into the cavity formed by the lamp envelope. The internal current conductors have a maximum diameter of 300 .mu.m and are welded to the metal foils in a place situated in the cavity formed by the lamp envelope, in a place situated in the pinch, or both in the cavity and in the pinch. The construction prevents explosion of the lamp as a result of cracking of the pinches caused by a discharge arc.

  • Halogen incandescent lamp
    Patent number: 4367428
    Abstract: Mains voltage halogen incandescent lamps according to the invention have at least one metal foil (25) incorporated in the pinch seal (22) of the lamp envelope (21) which extends into the cavity (23) enclosed by the lamp envelope (1) and is connected to an internal current conductor (29) situated entirely within said cavity (23). The lamps furthermore have a non-current-carrying supporting member (31) for said internal current conductor (29) which is embedded in the pinch seal (22) at a distance from the metal foil (25).

  • Halogen incandescent lamp
    Patent number: 4331900
    Abstract: Two-pinch mains voltage halogen incandescent lamp according to the invention have metal foils (6) in the pinches (5) which foils are connected to respective internal current conductors (8) and respective external current conductors (10). The metal foils (6) extend beyond the pinches (5) into the cavity (7) formed by the lamp envelope (1). The internal current conductors (8) do not penetrate into the pinches (5). The construction prevents explosion of the lamps as a result of cracking of either pinch caused by a discharge arc.
