Electroluminescent edge connect-composite lamp/strip and method of making the same

A process for providing a pair of electrical contact areas on one side of an electroluminescent lamp, comprising the steps of:

• providing a transparent substrate having a first conductive layer thereon, the first conductive layer having a first edge and a second edge;
• depositing an electroluminescent layer on the first conductive layer, the electroluminescent layer having an edge Spaced from the first edge;
• depositing a first insulating layer on the electroluminescent layer, the first insulating layer having an edge spaced from the first edge;
• depositing a second conductive layer on the first insulating layer, the second conductive layer having an edge spaced from the first edge;
• depositing a second insulating layer on the second conductive layer, the second insulating layer having an insulating end extending around and enclosing the edge of the second conductive layer and a second end spaced from the second edge;
• and
• depositing a film of conductive material on the second insulating layer, the film having a conductive end extending around the insulating end and making electrical contact with the first conductive layer and a second end spaced from the second edge.
