ABSTRACT:
Electroluminescent lamp designs and methods of fabricating electroluminescent lamps. Lamp designs provide laminar style lamps that include an electrically conductive layer with one or more openings therethrough separated by conductive elements. The openings preferably have a minimum edge to edge distance of less than about 0.005 inches and the conductive elements have a width of less than about 0.002 inches. Lamp designs also include "iso-planar" lamps that contain an electrically conductive layer with one or more channels separating the layer into two or more electrically conductive elements and an electroluminescent material disposed between the electrically conductive elements. The laminar style lamps and iso-planar lamps may be fabricated using printing techniques and the iso-planar lamps may also be fabricated using etching techniques. Both printed laminar and iso-planar lamps may be permanently reshaped using sheet forming techniques such as vacuum-forming or drape-forming.
