A process for manufacturing electroluminescent lamps using a laser beam to remove a material layer of a multi-layer material structure, in which the laser beam has a first energy level directed at a first material layer, e.g., a conductor, laid over a second material layer, e.g., an insulator/substrate. The laser beam is moved in an overlapping fashion such as spiral pattern motion across the first material layer. A part of the first material layer is sublimed exposing a region of the second material under the area where the spiral pattern was applied. Additionally, a second laser beam having a second energy level, e.g., higher than the first energy level, is moved along a path over the exposed second material layer subliming the remaining underlying layers to form the final lamp shape.
A process for removing material, the process comprising the steps of:
A process for fabricating an electroluminescent lamp, the process comprising the steps of:
A method of making an electroluminescent lamp including sequential front electrode, phosphor, dielectric and rear electrode layers, comprising laser etching the rear electrode to sufficient extent to electrically isolate the phosphor layer from said rear electrode layer.
A process for making electroluminescent lamps from an electroluminescent laminate having at least a first conductive layer, a phosphor layer, a dielectric layer and a second conductive layer, said process comprising the steps of:
A process for fabricating an electroluminescent lamp, the process comprising the steps of:
An electroluminescent lamp including sequential front electrode, phosphor, dielectric and rear electrode layers, wherein the rear electrode comprises a metalized film including a marginal region demetalized by spiral loop lasing to electrically isolate the phosphor layer from the rear electrode.
