Abstract
At least one conductive layer runs the length of an EL panel and individual lamps are connected to the conductive layer. In one embodiment of the invention, the electroluminescent layer of the panel does not cover a portion of the front electrode and the conductive layer is electrically coupled to the exposed portion of the front electrode. In another embodiment of the invention, the EL panel includes at least two rear electrodes and the conductive layer is coupled to one of the rear electrodes. An insulating layer between the conductive layer and other parts of the EL panel prevents unintended electrical connections to the conductive layer.
