Title
(EN) INTERNALLY ILLUMINATED SIGN
(FR) PANNEAU INDICATEUR A ECLAIRAGE INTERIEUR
(JA) 内部照明標識
Abstract
(EN)
An internally illuminated sign comprising an information display section having at least one flat or curved surface, exhibiting retroreflectivity to the light from the front surface of the sign and having a plane translucent to the light from the interior of the sign, an illuminator disposed on the back of the information display section, and a rectangular body for holding the information display section and the illuminator while closing. A retroreflective element being employed in the information display section is a prism type retroreflective element based on the principle of total internal reflection and a large number of prism type retroreflective elements are arranged while touching tightly each other to form a continuous retroreflective surface wherein at least the retroreflective part on the back of the large number of prism type retroreflective elements does not have a part coupling with other layers.
(FR)
L'invention concerne un panneau indicateur à éclairage intérieur comprenant une section d'affichage d'informations comportant au moins une surface plane ou courbe, permettant une rétroréflexion de la lumière depuis la surface avant du panneau et comportant un plan transparent à la lumière provenant de l'intérieur du panneau, un illuminateur situé derrière la section d'affichage d'informations, et un corps rectangulaire servant de support pour la section d'affichage d'informations et pour l'illuminateur. La section d'affichage d'informations comprend un élément de rétroréflexion sous forme de prisme à réflexion interne totale et des éléments de rétroréflexion sous forme de prismes en contact étroit les uns avec les autres pour former une surface de rétroréflexion continue, au moins une partie de la zone de rétroréflexion à l'arrière des éléments de rétroréflexion n'est pas en contact avec d'autres couches.
