Abstract
A lighting unit including an illumination element, and an electric circuit comprising electric power supply leads, coupled with the illumination element and operable to deliver electric power to the illumination element for actuation thereof, having an electric fuse integrally coupled to at least one of the leads to provide electrical isolation of the lighting unit in the event of an electrical short therein. The invention has particular utility in application to electroluminescent lamp units, of a type which is usefully employed in assembly of multi-unit electroluminescent lamp arrays. When provided in a parallel circuit arrangement comprising a multiplicity of individually fused lamps on a common power feed, the failure of any one lamp will not cause any other lamp to cease operation.
