ABSTRACT:
The unlit margin of a first EL lamp is covered by the lit edge of a second EL lamp to provide a substantially seamless lit area. The lamps are joined mechanically. The EL lamps are connected in parallel electrically by conductive tape overlying at least a portion of the bus bars of the lamps. A plurality of lamps can be joined together to provide an EL lamp substantially larger than obtainable by other means.
