Embodiment Construction

[0048] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In some instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

[0049] figure 1 A composite core electrode 5 according to some embodiments of the invention is schematically shown, which may include a copper wire 2 and a conductive compound layer 4 . The diameter of the copper wire 2 is, for example, approximately 0.5 mm. The concentric conductive compound layer 4 may have a thickness of, for example, approximately 0.5 mm. In some embodiments, therefore, the outer diameter of the composite core electrode 5 may be approximately 1.5 millimeters.

[0050] The conductive compound 4 may include, for example, PVD...

Abstract

The present invention provides an electroluminescent cable (10) and method of fabrication thereof. For example, an electroluminescent cable (10) includes a composite core electrode including an elongated flexible metal portion (2) substantially surrounded by one or more layers of a flexible conductive compound (4), the composite core electrode surrounded by a dielectric layer (6), an electroluminescent layer (8), a transparent conductive layer (12) and a polymer layer (16).

Description

technical field [0001] The present invention relates generally to electroluminescent light sources, and more particularly, to flexible, elongated electroluminescent light sources. Background technique [0002] Some flexible and extended electroluminescent light sources are known in the prior art, such as electroluminescent wires, electroluminescent filaments, electroluminescent cables, electroluminescent strips, electroluminescent substrates, and the like. Some flexible extended electroluminescent light sources may comprise a metal core electrode on which are sequentially applied a dielectric layer, an electroluminescent layer, a conductive transparent layer serving as an external electrode, and one or more The light-emitting polymer layers are spaced apart and colored in various colors. When an alternating voltage of suitable frequency and amplitude is applied to the core and outer electrodes, the electroluminescent layer emits light through the transparent electrodes. ...
