Abstract
An electric lamp is provided having an outer envelope or jacket with a lamp base attached thereto, the lamp base having an aperture extending therethrough. A sealed inner capsule is supported within the outer envelope and electrically connected to the lamp base and to an electrically conductive elongated member one end of which engages an inner wall of the outer envelope and an opposite end of which extends through the aperture in the lamp base. A spring is provided which urges the one end of the elongated member against the inner wall and which will urge the opposite end of the elongated member out of the aperture if the envelope is broken thereby disconnecting voltage to a lead of the inner capsule.
