Abstract

La présente invention se rapporte à un indicateur lumineux L'indicateur 10 comprend un cadran généralement circulaire 12 et une aiguille 18 constitués chacun d'une matière transparente ou translucide. Les rayons lumineux envoyés par une source lumineuse 28 à travers la partie périphérique 12a du cadran sont acheminés vers la partie d'extrémité de l'aiguille après deux réflexions successives sur les surfaces réfléchissantes 22 du cadran et 24 de l'aiguille. De ce fait, l'aiguille est éclairée à sa partie d'extrémité extérieure qui est formée d'une surface mate oblique 26 qui diffuse les rayons lumineux. La partie périphérique 12a du cadran joue un rôle de concentration de la lumière avant que celle-ci n'atteigne la surface réfléchissante 22 du cadran. La présente invention est notamment applicable aux indicateurs lumineux montés sur le tableau de bord des véhicules automobiles.The present invention relates to a luminous indicator. The indicator 10 comprises a generally circular dial 12 and a hand 18 each made of a transparent or translucent material. The light rays sent by a light source 28 through the peripheral part 12a of the dial are routed towards the end part of the needle after two successive reflections on the reflecting surfaces 22 of the dial and 24 of the needle. As a result, the needle is illuminated at its outer end portion which is formed by an oblique mat surface 26 which diffuses the light rays. The peripheral part 12a of the dial plays a role of concentrating the light before the latter reaches the reflecting surface 22 of the dial. The present invention is particularly applicable to light indicators mounted on the dashboard of motor vehicles.
