Abstract
(EN)
An optically interrupted linear fiber optic light strip (30) that includes a core (32), a clad (34), a first jacket material (36) that is made of substantially a translucent, white or other light color material, a second jacket (40), made of a black or dark opaque material, and a plurality of cuts, notches or other indented optical interruptions (38) in the form of 'Vs', squares or rectangles or other configurations extending through the two jackets, the cladding and into the fiber optic core, together with, optionally, a third or outermost jacket, made of a clear, protective material, which fiber optic strip may, optionally be illuminated with relatively high power LED source(s), or conventional incandescent light source(s) by placing the light sources at either end or both ends of the light guides.
(FR)
La présente invention concerne une bande lumineuse linéaire à fibre optique munie d'interruptions optiques (30), qui comprend : un coeur (32) ; une gaine (34) ; une première enveloppe protectrice (36) réalisée dans une matière sensiblement translucide blanche ou d'une autre couleur claire ; une seconde enveloppe protectrice (40) réalisée dans une matière opaque noire ou sombre, une pluralité de fentes, d'entailles ou d'autres interruptions optiques en creux (38) en forme de V, de carrés ou de rectangles ou d'autres configurations s'étendant à travers les deux enveloppes protectrices, la gaine et le coeur de la fibre optique ; et, facultativement, une troisième enveloppe protectrice le plus à l'extérieur, réalisée dans une matière protectrice transparente. La bande de fibre optique de l'invention peut être facultativement illuminée par une ou des diodes électroluminescentes de relativement haute puissance ou par des sources lumineuses incandescentes traditionnelles qui sont placées à l'une ou l'autre ou aux deux extrémités du guide optique.
