ABSTRACT:
An electroluminescent panel and method of making the same includes a plurality of layers on a transparent electrode in which each layer is formed with the same compatible polymer carrier resin base material so that the individual layers have an integrated uniformity. A polyester laminating resin is disclosed for the resin base material of each layer which is activated by a small amount of diisocyanate sufficient to provide temperature stability, but insuffient to transform the base material into a urethane. Also disclosed is an electroluminescent lamp which emits light only in discrete areas such as to produce a pattern of light in which the phosphor is applied in a pattern corresponding to the discrete areas which are to be illuminated. Similarly, the electrodes are restricted to the illuminated regions or areas, thereby conserving material as well as reducing the power requirements of the lamp. Also disclosed is an electroluminescent lamp in which the power leads are applied to the lamp at locations inwardly of the margin of the lamp, and a method of attaching the power leads inwardly of the lamp margins.
