Abstract
An elastomeric electroluminescent (EL) lamp is provided wherein an electroluminescent system, advantageously monolithic, is provided in an elastomeric structure. As a result, the lamp is thin, pliable and membrane-like. A first envelope layer is applied advantageously by screen printing to transfer release paper. An EL system is then applied, again advantageously by screen printing to the first envelope layer, and then a second envelope layer is applied to seal the EL system within the envelope. Appropriate windows are cut or left open to allow electrical contact with the EL system. An optional adhesive layer then may be applied if the lamp is to be used in transfer form for later affixation to a substrate. Alternatively, the lamp may be used as a self-contained elastomeric component installed in another product.
