ABSTRACT:
The method of providing a pair of contact terminals on the back side of an electroluminescent (EL) lamp, of the type which has EL material between front and back conductive layers, which are disposed on a transparent substrate. A bump of conductive material deposited on the front conductive layer is insulated from the back conductive layer for providing a contact terminal on the back of the EL lamp which is connected to the front conductive layer. A preferred embodiment includes the further steps of adding an extension which relocates the back connection to a different place on the back of the EL lamp.
