The lighting element or lamp is encapsulated in a moisture impervious material. A process for manufacturing an elongated electroluminescent light strip is also provided.
Claims10
A process for the manufacture of an elongated electroluminescent light strip comprising the steps of:
- a) feeding an elongated electroluminescent lamp which includes an electrically conductive layer, a substantially moisture resistant phosphor matrix layer including a coating Of hydrolyzed trimethylaluminum and spaced apart bus strips, wherein said bus strips extend from said electroluminescent lamp to an extruder;
- and
- b) encapsulating the elongated electroluminescent lamp in an extrudate by continuously extruding a polymeric material about said electroluminescent lamp to fully encapsulate said electroluminescent lamp.
A process for the manufacture of an elongated electroluminescent light strip comprising the steps of:
- (a) forming an elongated electroluminescent lamp including an electrically conductive layer, a phosphor matrix layer which is coated with hydrolyzed trimethylaluminum disposed along one side against said electrically conductive layer, a second electrically conductive layer disposed along a second side of said phosphor matrix layer and a pair of spaced apart bus strips, said bus strips being disposed such that one bus strip is in contact with each electrically conductive layer, wherein said bus strips extend from the electroluminescent lamp to an extruder;
- and
- (b) encapsulating the elongated electroluminescent lamp in an extrudate by continuously extruding a polymeric material about said electroluminescent lamp to fully encapsulate said electroluminescent lamp.
