Electric lamp with stress relieving means |
摘要 |
An electric lamp (e.g., tungsten-halogen) wherein a glass bridge (31) is used and has the support wires (23) of the lamp's filament structure (13) passing therethrough. The support wires are indented (e.g., with V-shaped notches) on opposing sides thereof just below the bridge to permit movement of the portions of the support wires between the bridge and press-sealed end (17) of the lamp's envelope (11) during press-sealing, thereby substantially relieving stresses on the bridge (31) and possible breakage thereof as may occur if such wires were retained in a fixed, non-movable arrangement.
