Abstract
Abstract An integral, light weight, recyclable, self-contained battery operated and insulated lighting system using an electroluminescent light source is described. This is achieved by re-locating the terminals of an electroluminescent light source away from the outer edges, securing the power supply unit onto the body of the light source, and encapsulating both the electroluminating light source and the converter into one unit. On-off control, if desired, is incorporated in the same unit using a commercial membrane switch. Only the low voltage D.C. end of the converter is therefore exposed for attachment to a regular battery which may also be encapsulated with the converter and light source into one single unit, increasing further the water and electrical resistivity and hence the safety of the system. The system is recyclable. A damaged or spent unit can be removed, replaced, followed by the re-encapsulation of the entire system.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
An improved electroluminescent lighting system using a conventional electroluminescent light source having a luminescent face, a non-luminescent face, and external edges, the improvement comprising: (a) at least two electric termination points positioned on the non-luminescent face of said light source and at a distance from the external edges; (b) an energizing module attached to said termination points by a connecting means and positioned by an adhering means on the non-luminescent face of said light source at a distance from the external edges; and (c) a resilient and water resistant cover encapsulating the luminescent face, the non-luminescent face, and the external edges of said light source, said termination points, said energizing module, and said connecting means.
Claim 2
Dependent Claim
