  • Incandescent lamp with vibration-protected filament mount
    Patent number: 4180757
    Abstract: An incandescent lamp has a coiled filament with an improved life when it is mounted substantially in the same direction in which a mechanical shock occurs. In a particular embodiment of a miniature lamp known as a switchboard lamp, the filament is mounted, without further support, between two posts. This results in a greater light effectiveness that permits a current reduction through the filament while maintaining desired light output levels in its operational environment. The filament is protected from harmful shock levels by being mounted between twisted posts which orient the filament in the general direction of a mechanical shock imparted to the lamp through key telephone button releases.
