Abstract

L’invention concerne un moyen d’éclairage allongé (5), c’est-à-dire une lumière de type câble, et ses procédés de fabrication. Le moyen d’éclairage comprend des conducteurs allongés sensiblement parallèles (6a, 6b) s’étendant dans le sens de la longueur et des dispositifs électroluminescents (9) espacés le long de la longueur du moyen d’éclairage et connectés de part et d’autre des conducteurs. Le moyen d’éclairage possède un corps interne allongé (7) avec des évidements (90) logeant les conducteurs. Une partie de chaque conducteur dépasse de l’évidement dans lequel il est logé et cette partie est connectée aux dispositifs électroluminescents, par exemple par brasage. L’ensemble corps interne, conducteurs et dispositifs électroluminescents est gainé dans un revêtement translucide ou transparent externe (10). Le corps interne et le revêtement externe sont de préférence formés par extrusion d’élastomères de silicone. Selon un procédé de fabrication préféré, le corps interne est extrudé avec les conducteurs pour constituer un câble (12), le matériau du corps interne gainant complètement les conducteurs. On arrache ensuite les morceaux (14, 15) dans le sens de la longueur de ce matériau pour exposer les portions de conducteur. Les dispositifs électroluminescents sont ensuite connectés, et l’ensemble résultant est gainé par extrusion du revêtement externe par-dessus celui-ci.
