ABSTRACT:
Electric lamp inlead wires are provided with bends to shape them into desired configurations for holding a filament or arc tube. The bends are shaped to provide a small reverse bend section. This prevents an inherent springback tendency at the bends, and improves the permanency of the bent shapes.
