Patent number: 7425079Abstract: A mountable electroluminescent welt that is easier to attach to a desired surface or joint. The welt includes an electroluminescent light which includes a center conductor and at least one outer conductor with an electroluminescent chemical dispersed therein that undergo electroluminescence when excited with by a suitable AC current. The welt includes a transparent or semi-transparent sheath casing circular or oval in cross-section with at least one integrally formed, laterally extending wing member. The wing member is a relatively thin structure that extends longitudinally over a portion or the entire length of the outer casing. In the preferred embodiment, the outer edges of the wing member are converged towards their outer edges thereby enabling the wing to be placed into a joint space. A suitable attachment means, such as sewing, an adhesive, or a closed joint, may be used to attach the wing to the desired surface or joint while allowing the outer casing to be exposed.Type: GrantFiled: May 20, 2002Date of Patent: September 16, 2008Inventors: Kevin Bruce, Luis Lorca-Merono
