Abstract
Several means are described for providing an electrical coupling path through a protective, insulative layer, e.g. cellulose acetate, located on an electrically activated flash lamp envelope. The function of the path is to interconnect a thin conductive coating positioned on the envelope's external surface under the insulative layer with an electrical contact located externally of the flash lamp and adapted for igniting the lamp.
