ABSTRACT:
An electroluminescent panel lamp being of either a split-electrode or parallel plate type is disclosed wherein the lamp consists of a main body having an electroluminescent layer between first and second conductive layers. An integral electrical connector tab is formed from the materials of the main body. In the parallel plate embodiment the first conductive element is exposed so as to form a front electrode, the rear electrode being the second conductive layer. In the split-electrode embodiment, the second conductive layer on the main body and connector tab is split into two halves, the two halves on the tab being the electrical connections and lying in the same plane. An alternating current charge applied to one half of the split second conductor will capacitively couple it to the other half through the unconnected first conductor. A universal connector that can connect an electrical power source to either the parallel plate or split-electrode embodiment is also disclosed. The connector has a pair of spaced apart contact fingers of different lengths that contact the front and rear electrodes of the parallel plate lamp or both halves of the second conductor in the split electrode lamp.
