Abstract

Conducteur de lumière (10) destiné à éclairer un dispositif d'affichage et/ou un clavier, fait en matière translucide et ayant la forme d'un élément plan avec un bord périphérique (24). Un certain nombre de raccords se trouvant sur l'un des côtés et ayant la forme d'enfoncements arqués (150) transmettent la lumière depuis des sources de lumière vers le conducteur de lumière (10) de façon parfaitement régulière. Un certain nombre d'enfoncements réfléchissants de forme arquée (60, 62) qui se trouvent sur le bord périphérique (24) réfléchissent la lumière au niveau du bord pour la renvoyer vers le conducteur de lumière (10) afin que les touches de l'appareil soient bien éclairées.
