Abstract
An electroluminescent supplementary lighting device having three-dimensional configuration will typically have a curved front face, or a partial conical front face; or have the configuration of a truncated pyramid. The entire front face is light emitting when the device is plugged into a wall receptacle. The front face is translucent, and an electroluminescent panel having substantially the same configuration as the front face underlies the front face within the attached interior of the lighting device. A connection tab extends from an edge of the electroluminescent panel into an enclosed volume within the lighting device, where connections are made to electrical prongs so as to provide a voltage across the electroluminescent phosphor lying within the electroluminescent panel between the electrically conductive front and back sheets.
