Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
59 words
A process for manufacture of an elongated electroluminescent light strip comprising the steps of: a) continuously feeding an elongated electroluminescent lamp having bus elements extending therefrom to an extruder; and b) extruding a plastic extrudant at a temperature less than that which would damage said elongated electroluminescent lamp about said elongated electroluminescent lamp to entirely encapsulate said electroluminescent lamp.
Claim 2
Dependent Claim
59 words
A process for manufacture of an elongated electroluminescent light strip comprising the steps of: a) continuously feeding an elongated electroluminescent lamp having bus elements extending therefrom to an extruder; and b) extruding a plastic extrudant at a temperature less than that which would damage said elongated electroluminescent lamp about said elongated electroluminescent lamp to entirely encapsulate said electroluminescent lamp.
Claim 3
Dependent Claim
25 words
The process of claim 1 comprising the further step of interposing a layer of semi-transparent film over said electroluminescent lamp prior to the encapsulating step.
Claim 4
Dependent Claim
11 words
The process of claim 1 wherein said extrudant comprises ionomer resin.
Claim 5
Dependent Claim
12 words
The process of claim 1 wherein said extrudant comprises high density polyethylene.
Claim 6
Dependent Claim
10 words
The process of claim 1 wherein said extrudant comprises polychlorotrifluoroethylene.
Claim 7
Dependent Claim
46 words
The process according to claim 1 further comprising the step of positioning a bus bar along the entire length of the electroluminescent light strip on either side of the electroluminescent lamp for electrically energizing the electroluminescent lamp along substantially the entire length of the light strip.
