Patent

CA 2323579

The invention is a temporary or emergency lighting system constituted by a bearing structure (2) made of flexible plastic material and having one or more light sources (4) at its top and a support base (1) at its bottom. The structure, which is kept constantly inflated by means of a fan (6), is constituted by one or more superimposed cylinders or cones that are internally divided in sections (2, 1) in order to ensure the progressive and vertical inflation of the structure. The structure can be folded in order to reduce the dimensions of the system as much as possible when it is closed and to make it possible to carry it on the shoulders. The light source is fixed or provided with a rotary mirror (8), in such a way as to direct or rotate the light beam. Some cords or tensioning elements (3) are provided on the structure to limit the height of the bearing structure. The power supply to fans, various functions and/or light source can be guaranteed through a current generator, the power mains or batteries.

L'invention se rapporte à un système d'éclairage temporaire et/ou d'urgence comportant une structure porteuse (2) en matière plastique souple et possédant une ou plusieurs sources lumineuses (4) au niveau de sa partie supérieure et une base de support (1) au niveau de sa partie inférieure. La structure, qui est maintenue en permanence à l'état gonflé au moyen d'un ventilateur (6), est constitué d'un ou de plusieurs cylindres ou cônes superposés qui sont divisés intérieurement en sections (2, 1) permettant un gonflage progressif et vertical de la structure. Cette dernière peut être pliée de façon à réduire autant que possible l'encombrement du système lorsqu'il est fermé et à le rendre transportable sur les épaules. La source lumineuse est fixe ou installée sur un miroir pivotant (8) de manière à diriger ou faire tourner le faisceau lumineux. Plusieurs cordons ou éléments tendeurs (3) sont fixés sur la structure et servent à réduire sa hauteur. L'alimentation des ventilateurs, de divers organes et/ou sources lumineuses peut être assurée par un générateur de courant, le secteur ou des batteries.
