  • Each module is made up of a two part enclosing body or shell.
  • the shell is generally triangular in cross section through the vertical axis of the module, but with rounded corners, thereby forming what is called herein a tri-liptic shape, since it has both triangular and elliptical characteristics.

  • a base unit may be provided with one or more modules arranged vertically above the base.
  • the base unit may be a shell which contains an audible signaling device.
  • a cover is preferably connected over the top of the upper most module to seal the unit.
  • a panel providing the part, which forms the remaining side of tri-liptic shape is attached to close the other part to the module, thereby providing an enclosure containing the light source which is sealed against adverse environmental affects.

Abstract

L'invention concerne un dispositif de signalisation visuelle, pourvu de modules de source lumineuse empilables (10). Chacun de ces modules (10) est 'triliptique', c'est-à-dire de forme généralement triangulaire, les coins du triangle étant néanmoins arrondis. A l'intérieur de ce triangle, un cercle parfait contribue à la dispersion optique de ladite source lumineuse (74). Chacun desdits modules est formé d'une pièce moulée arrière (18, 20) et d'une pièce moulée avant (22). Le module de source lumineuse (10) contient une source lumineuse (26), placé sur une plaque de circuit imprimé (70). Ce module contient également un dispositif électronique qui commande ladite source lumineuse, la faisant clignoter ou l'éclairant en permanence, ou un réflecteur pivotant autour d'une ampoule fixe (74). Un conduit (60), constitué d'une bande de plaque de circuit imprimé pourvue de connecteurs à ses extrémités opposées, s'étend entre les parties supérieure et inférieure de chaque module de la pile. La plaque contenant la source lumineuse est insérée par l'intermédiaire de glissières (76) dans un autre connecteur, fixé audit conduit. Le module de source lumineuse (10) peut être rapidement retiré et interconnecté à une pile par raccordement des parties supérieure et inférieure des pièces moulées arrières des modules adjacent de la pile, grâce à des parties saillantes et à des fentes (36, 38) qui s'emboîtent les unes dans les autres. Un couvercle (14) et un socle (12) peuvent également être raccordés aux modules supérieur et inférieur de la pile, le socle pouvant contenir un avertisseur sonore (82). Le raccordement des différents modules de la pile ne nécessite pas l'utilisation de tiges ou de vis séparées traversant la pile entière.
