Electroluminescent ornaments and display systems
View Patent ↗Electroluminescent holiday lighting systems are provided including electroluminescent ornaments of varying constructions. An ornament shell or base has a layered construction including a base conductor, active conductor, electroluminescent layer and numerous insulation and protective layers. The electroluminescent layer is activated by a controller that selectively applies an activation bias to the ornament to illuminate it under specific conditions. Numerous ornament and lighting system controllers are also provided for controlling electroluminescent lights and displays, some in combination with other lighting technologies such as LED systems.
1. An ornament comprising:
a shell having a plurality of coatings applied to the shell, said plurality of coatings being layered on the shell and including a base conductor layer, an active conductor layer, and an electroluminescent layer disposed between the base conductor layer and the active conductor layer; and
an electronics platform having a DC/AC converter and a DC power supply, the DC power supply coupled to the DC/AC converter, and the DC/AC converter having a first lead electrically coupled to the base conductor layer and a second lead electrically coupled to the active conductor layer, the electroluminescent layer being illuminated when the DC power supply is in an active state;
wherein the electroluminescent layer includes a plurality of portions; and
wherein each of the plurality of portions is coated with a different color electroluminescent material.
2. The ornament of claim 1 , wherein the plurality of coatings includes a first insulating coating disposed between the base conductor layer and the electroluminescent layer, and a second insulating coating disposed between the electroluminescent layer and the active conductor layer.
3. The ornament of claim 1 , wherein the plurality of coatings includes an outer protective coating encasing the plurality of coatings between the shell and the outer protective coating.
4. The ornament of claim 1 , wherein each of the plurality of portions is a different-colored, wedge-shaped portion disposed along the shell.
5. The ornament of claim 1 , wherein each of the plurality of portions is a different-colored, vertically-oriented, wedge-shaped slice disposed along the shell.
6. The ornament of claim 1 , wherein the active conductor layer is a fine wire weave layer.
7. The ornament of claim 2 , wherein the first and second insulating coatings are clear coatings.
8. The ornament of claim 1 , wherein the ornament is a Christmas ornament and the shell is a Christmas ornament shell.
9. A lighting device, comprising:
a base conductor;
a first insulating layer disposed on the base conductor;
an electroluminescent layer disposed on the first insulating layer;
a second insulating layer disposed on the electroluminescent layer; and
an active conductor layer disposed on the second insulating layer;
wherein the electroluminescent layer includes a plurality of portions; and
wherein each of the plurality of portions is coated with a different color electroluminescent material.
10. The lighting device of claim 9 , wherein the lighting device is a branch of a decorative artificial tree.
11. The lighting device of claim 9 , wherein the lighting device is selected from the group consisting of a needle of an artificial Christmas tree, a leaf of an artificial holiday wreath, and a leaf of an artificial holiday tree.
12. The lighting device of claim 9 , wherein the lighting device is a branch of a decorative artificial tree.
13. The lighting device of claim 9 , further comprising an electrical converter having a first lead and a second lead, the first lead being electrically connected to the base conductor and the second lead being electrically connected to the active conductor layer.
