Abstract: La grille comprend une pluralite de passages de lumiere (3) delimites par des parois (4, 5, 6, 7) de hauteur appropriee et disposes a une distance mutuelle appropriee permettant a la lumiere emise par une source lumineuse (9) de se propager dans lesdits passages de lumiere. La grille comprend au moins deux organes de grille plans independants et paralleles (1, 2) disposes l'un pres de l'autre ou ecartes d'une distance predeterminee. Les organes de grille peuvent etre fixes l'un a l'autre par de moyens de retention (8), par exemple des connexions rapides. Les organes de grille peuvent etre du meme type ou de types differents de telle sorte que, par exemple, les deux organes soient des grilles ecran ou que l'un des organes soit une grille ecran alors que l'autre, de preference l'organe de grille inferieur, peut etre une grille a basse luminence a miroir. En fabriquant une grille constituee de deux organes espaces il est possible de placer les parois (4, 5, 6, 7) a une distance plus grande, ce qui permet une economie de materiau tout en maintenant l'angle d'ecran habituel. Une telle construction permet en outre de reduire l'epaisseur des parois par rapport aux grilles de types connus, ce qui implique une economie de materiau supplementaires. Le poids total de la grille est ainsi reduit de facon notable. De plus de nouveaux effets lumineux sont rendus possibles en donnant des couleurs differentes aux organes de grille.
