CA 2241838

An optical fiber conduit (32) comprising an optical fiber core (22) surrounded by a cladding (24) with a reflective material or holder and/or reflector (34) attached adjacent to or in contact with the cladding (24) covered optical fiber core (22) along its longitudinal length and includes a plurality of illuminators (28-30) that are formed by uniform cuts (41) in the optical fiber core (22) emit reasonably even light perpendicularly along the length of the conduit (32) outwardly. The light pattern can be made to emit various beam patterns from very narrow to very wide by altering the shape of the optical fiber core (22) and/or by the cuts (41). The cut optical fiber is embedded in a clear environmentally protective coating to protect the cuts (41) from dust and moisture and to maintain the alignment of the holder and/or reflector (34) with optical elements (106) and the optical fiber core (22).

L'invention porte sur un canal optique fait d'une fibre optique (32) comportant une âme (22) entouré d'une gaine (24), et un matériau réfléchissant, ou support et/ou réflecteur (34) situé à proximité de l'âme, ou contre l'âme (22) recouverte par la gaine (24), sur toute sa longueur. L'âme (22) comporte une série de sources lumineuses (28, 30) consistant en incisions uniformes (41) pratiquées dans l'âme (22) et émettant vers l'extérieur de la lumière sensiblement uniforme perpendiculairement à l'axe longitudinal du canal (32). L'émission de lumière peut être réglée pour émettre différentes formes de faisceaux lumineux, du très étroit au très large, en modifiant la forme de l'âme (22). La fibre optique incisée est noyée dans un revêtement transparent protégeant les incisions (41) de la poussière et de l'humidité et maintenant l'alignement du support et/ou du réflecteur (34) avec les éléments optiques (106) et l'âme (22) de la fibre optique.
