Claim:
An incandescent electric lamp comprising: a bulb having an axis of revolution; a first and a second conductor wire designed for supplying said lamp with current; a filament having turns spiraling around an axis of revolution which is parallel to the axis of revolution of said bulb and having a first and a second end, the first end of said filament being connected to the first conductor wire by a first metal plate; and a metal support having a first and a second end, the first end of said metal support being connected to the second conductor wire by a second metal plate, while the second end of said metal support is connected to the second end of said filament, wherein the lamp comprises a metal bracket which is connected through a current conductor to the first or second conductor wire, has an unsecured end and comprises a portion substantially parallel to the axis of revolution of said filament, which portion is located directly opposite at least a portion of the filament and situated below and directly adjacent said filament when the lamp is in its normal operating position, wherein said filament and portion of the metal bracket are arranged such that a change in position of said filament causes said filament to contact the portion of the metal bracket.
