Abstract:

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.
