  • Lamp with internally pressed fuse
    Patent number: 5345144
    Abstract: A press sealed lamp with an internally pressed fuse is disclosed. The filament structure is conveniently formed so the fuse links across a looped section of the initial filament structure. The loop structure provides strength to the fused filament structure prior to sealing. After the lamp is sealed, a portion of the exposed loop is trimmed, thereby limiting the electrical connection to the path through the fuse.
