Abstract
A method for forming an electroluminescent lamp unit. A multi-layer sheet form electroluminescent lamp, the multi-layer sheet form lamp includes a pair of sheet-form conductive layers, one of which is transparent for transmitting light emitted from the particles, an electroluminescent sheet-form layer disposed between the pair of sheet-form conductive layers and having electroluminescent particles, and a carrier substrate for supporting the pair of sheet-form conductive layers and electroluminescent sheet-form layer. The multi-layer sheet form lamp is heated at a temperature sufficient for maintaining the operational integrity of said carrier substrate and said thermoplastic layers. The multi-layer sheet form lamp is them formed into a desired three-dimensional shape.
