Abstract

L'invention concerne un dispositif d'éclairage linéaire à diodes électroluminescentes comprenant une lentille linéaire (21), au moins translucide, d'axe longitudinal parallèle à l'axe longitudinal (L) du corps (2), avec une face externe d'émission (22) de la lumière et une face interne de réception (23) de la lumière des diodes (5), dont - la face d'émission (22), vue en section droite transversale, possède une partie centrale (24) de forme générale convexe et protubérante bordée par deux parties latérales planes, chaque bord de la partie centrale formant avec la partie plane correspondante un angle, mesuré à l'extérieur de la lentille linéaire, inférieur ou égal à 95°, et - la face de réception (23), vue en section droite transversale, comprend : - une région centrale (30) en partie au moins concave située en regard de la région centrale de la face d'émission pour former une cavité d'accueil des diodes, deux parties latérales planes sensiblement parallèles aux parties latérales planes de la face d'émission pour former deux ailes (32) latérales de diffusion de la lumière qui bordent la lentille linéaire (21), chaque bord de la région centrale formant avec la partie plane correspondante un angle, mesuré à l'intérieur de la lentille linéaire, supérieur ou égal à 100° et de préférence supérieur à 110°.
