Definitions

  • emergency illumination is at best a secondary feature of the design with light radiated through the lower extremity of the sign housing or blade having travelled through the sign body first and therefore being limited both in intensity and angle of projection.
  • Figure 5 is a detailed sectional side view of a cartridge with a different internal configuration to that of Figure 4. Detailed description of the Preferred Embodiment
  • the light emerging from the outer surfaces of the body halves back illuminates the signs carried on the sign carrying surfaces of the respective body halves, while the light emerging from the inner surfaces of the body halves travels across the cavity 31 and through the opposite walls 35 of the sign carrying element 12 to back illuminate the signs carried over the opposite outer surfaces of the sign carrying element.
  • light is refracted and/or reflected towards the respective sign carrying surfaces 33 by virtue of the corrugated surfaces 32 bounding the interface between the cavity 31 and the respective wall portions 35 of the sign carrying element 12.
  • Other possible internal reflection modes involve light undergoing multiple internal reflections within one of the body halves before emerging from one of the surfaces 32, 33.

Abstract

L'invention concerne un élément porteur d'un panneau éclairé intérieurement d'un ensemble panneau/éclairage d'urgence, dans lequel une unité de base (11) est agencée pour être montée sur un plafond (33), le corps du panneau (12) s'accrochant sur la base. L'élément porteur du panneau (12) s'étend en dessous de la base (11) et peut se détacher de celle-ci. Une connexion électrique entre le dispositif porteur (12) et le module électronique (16) de la base (11) s'effectue par l'intermédiaire d'une paire de connecteurs électriques coopérants (24, 25). L'élément de panneau (12) est formé dans un matériau transparent, semi-transparent ou translucide et il est moulé sous la forme d'une paire de moitiés de coquille, lesquelles, lors de leur assemblage, enferment deux sources lumineuses (26, 27), dont une, supérieure (source 26) exécute une fonction normale d'éclairage de panneau, l'autre source (27) exécutant une fonction d'éclairage d'urgence, de sorte que le panneau est éclairé, de même qu'une zone environnante du plancher, lors de conditions d'urgence. La base (11) loge des batteries (14), transformateurs (15) et un module électronique (16), lequel comporte les circuits de commande de communication, de charge des batteries, de surveillance du dispositif, et de ballast électronique, nécessaires à l'exécution des fonctions d'éclairage d'urgence et d'éclairage du panneau.
