Abstract
An electroluminescent sheet-form lamp comprising a transparent insulation layer, a transparent first conductive layer below the insulation layer forming a first electrode, a layer of phosphor material below the first conductive layer, a layer of dielectric material below the phosphor layer, a second conductive layer below the dielectric layer forming a second electrode, and electrical connection means for applying an electrical potential between the conductive layers to cause the phosphor to transmit light through the transparent conductive layer and the transparent insulation layer, one of the conductive layers having been formed as a general conductive coating preapplied over a panel of larger dimension than the lamp, from which the lamp has been cut. The lamp provides an improved electrical connection, wherein the one conductive layer has a line of interruption which isolates a localized region of the one conductive layer from electrical continuity with a main portion of the one conductive layer, the main portion of the one conductive layer forming the respective electrode and being connected to one of the connection means to apply electrical potential thereto without applying e…
