Abstract

Cet indicateur de planche de bord d'automobile comporte derrière un cadrant (11) un prisme transparent tel que la lumière provenant d'une source lumineuse traversant le prisme vient éclairer une aiguille montée sur le cadrant (11). Le prisme (20) comporte un élément réflecteur faisant converger la lumière de la source lumineuse (30) vers une zone centrale υ de la source lumineuse. Un axe (40) monté par un trou traversant (23) dans le prisme (20) présente en son extrémité supérieure une partie concave (40B). Une aiguille (40), dont une troisième partie est réfléchissante, est montée sur la partie concave (40B) de l'axe (40A) permettant de réfléchir en direction de l'aiguille (40) la lumière renvoyée vers la zone centrale υ depuis le prisme (20).
