More Information
Summary:An electric lamp construction is described having at least one pair of conductive inlead wires of dispersion strengthened copper alloy to serve as the sole means of the physical support for a resistive incandescent filament physically connected thereto, and wherein one of said inlead wires is further electrically connected to a fuse lead of a copper solution alloy with nickel and tin. Said fuse metal produces less metal arc damage when melted during the lamp operation as compared with other fuse metals now in commercial use.
