Abstract

An electric lamp at least one end of which is provided with a gas-tight seal having at least one metal foil sealed therein, said metal foil having secured to it the end of a current supply wire projecting outside the lamp, as well as the end of a pole wire projecting inside the lamp, with the special feature that said metal foil is bent so as to shorten its length in the longitudinal direction of the lamp.
