ABSTRACT:
An electroluminescent (EL) lamp having at least two integral fusible links and a method of manufacturing such a lamp are disclosed. The present invention provides for a fusible link between the front electrode input power contact area and the transparent electrode. In addition, the present invention provides a second fusible link between the back electrode input power contact area and the transparent electrode. The fusible links are designed to become non-conductive (open) if a certain current level is exceeded. The EL lamp fails in a controlled way, without signs of combustion. The EL lamp is therefore protected from self-destruction when subject to an anomaly or manufacturing defect.
