Abstract

A phosphor coated film laminate is produced in a continuous coil suitable for further processing to provide an electroluminscent lamp construction and lamp. Dielectric material is applied to the phosphor surface of the film laminate in a desired shape by screening or punching and electrical connections are formed on the front and read conductors of the EL lamp. A continuous coil of electroluminscent lamps and construction is also described.

Claims

1. Method for electroluminescent (EL) lamp construction comprising the steps of:

providing a first continuous roll having a length and a width dimension of an electroluminescent phosphor coated conductor film comprising a conductive layer laminated between a phosphor particulate layer and an optically clear protective film layer and defining a front conductor laminate;

applying a dielectric layer on the phosphor surface side of the front conductor laminate;

applying a conductor layer on the dielectric layer and defining a rear conductor laminate;

joining said front and rear conductor laminates defining a parallel plate EL lamp, and

attaching a connector to the conductive layer.

2. The method of claim 1 further including the step of providing an ITO conductive layer.

3. The method of claim 1 further including the step of providing a polymer conductive layer.

4. The method of claim 1 further including the step of enveloping the joined front conductor and rear conductor laminates defining the parallel plate EL lamp.

5. The method of claim 1 wherein the step of applying a dielectric layer further comprises the step of printing the dielectric layer on the phosphor layer.

6. The method of claim 1 wherein the step of applying a dielectric layer on the phosphor surface side further comprises the steps of:

providing a dielectric coated conductive film comprising an aluminum foil conductive layer laminated between a dielectric layer and an optically clear protective film layer and defining a rear conductor, and

laminating the dielectric coated conductive film to the phosphor coated conductor film.

7. The method of claim 6 further including the step of cutting the rear conductor in the desired size and shape of the parallel plate EL lamp prior to the step of laminating the dielectric coated conductive film to the phosphor coated conductive film.

8. The method of claim 6 further including the step of punching out one or more pieces of the rear conductor in the desired sizes and shapes of the parallel plate EL lamp during the step of laminating the dielectric coated conductive film to the phosphor coated conductor film.
