Claims
- 1. An electroluminescent lamp module comprising;
- a substrate having a relatively large lamp receiving surface, having an array of conductive traces disposed on said surface and
- a plurality of multi-layer sheet-form electroluminescent lamps, each comprising a sheet-form layer containing electroluminescent particles, said layer disposed between a pair of sheet-form conductive layers, one of which is transparent for transmitting light emitted from said particles, each of said lamps having conductors exposed for engagement with said conductive traces on said substrate, each of said lamps being of area smaller than said substrate and placed thereupon, said lamps being permanently secured face-to-face to said substrate by securing structures, each of which penetrates respective mating surfaces of each of said lamps and said substrate, said securing structures at least partially extending through the respective lamps and said substrate and being permanently joined thereto.
- 2. The electroluminescent lamp module of claim 1 wherein a first one of said plurality of electroluminescent lamps has a first light emitting characteristic that is different from a light emitting characteristic of a second one of said plurality of electroluminescent lamps.
- 3. The electroluminescent module of claim 1 wherein said light emitting characteristics of said first and second lamps comprise colors, whereby the color of said first lamp is different from the color of said second lamp.
- 4. The electroluminescent module of claim 1 wherein said light emitting characteristics of said first and second lamps comprise lamp intensities, whereby the intensity of said first lamp is different from the intensity of said second lamp.
- 5. The electroluminescent module of claim 1 wherein said substrate is a flexible substrate.
- 6. The electroluminescent lamp module of claim 1 wherein said plurality of electroluminescent lamps are flexible.
- 7. The electroluminescent lamp module of claim 1 wherein said transparent sheet-form conductive layer of at least one of said electroluminescent lamps is disposed adjacent said lamp receiving surface of said substrate, said substrate including transparent portions to permit light emitted from said at least one electroluminescent lamp to pass through said substrate.
- 8. The electroluminescent lamp module of claim 7 further comprising flexible conductive connectors electrically connecting exposed conductors disposed on the other of said pair of sheet-form conductive layers of said at least one electroluminescent lamp to said conductive traces on said substrate.
- 9. The electroluminescent lamp module of claim 1 wherein said securing structures comprise portions of said substrate that have been mechanically deformed.
- 10. The electroluminescent lamp module of claim 1 or 9 including a thermal bond between a substance of said lamp and a substance of said substrate in the region of said securing structures.
- 11. The electroluminescent lamp module of claim 10 wherein said thermal bond comprises an ultrasonic weld.
- 12. The electroluminescent lamp module of claim 1 wherein each of said securing structures extends through the entire thickness of corresponding portions of said sheet-form lamp and substrate.
- 13. An electroluminescent lamp module comprising:
- a flexible substrate having a relatively large lamp receiving surface, having an array of conductive traces disposed on said surface; and
- a plurality of flexible, multi-layer sheet-form electroluminescent lamps, each comprising a sheet-form layer containing electroluminescent particles, said layer disposed between a pair of sheet-form conductive layers, one of which is transparent for transmitting light emitted from said particles, each of said lamps having conductors exposed for engagement with said conductive traces on said substrate, each of said lamps being of area smaller than said substrate, said lamps each being placed on said substrate and permanently secured face-to-face thereto by localized ultrasonic weld regions between said mating surfaces of said sheet-form lamp and substrate with said lamp and substrate being mutually deformed at said weld regions, said lamps having conductors engaging corresponding conductive traces of said array.
- 14. The electroluminescent lamp module of claim 1 or 13 wherein said transparent sheet-form conductive layer of at least one of said electroluminescent lamps is disposed adjacent said lamp receiving surface of said substrate, said substrate including transparent portions to permit light emitted from said at least one electroluminescent lamp to pass through said substrate.
- 15. The electroluminescent lamp module of claim 14 further comprising flexible conductive connectors electrically connecting exposed conductors disposed on the other of said pair of sheet-form conductive layers of said at least one electroluminescent lamp to said conductive traces on said substrate.
