Abstract

L'invention concerne un procédé de fabrication d'une lamelle (10) pouvant être éclairée pour un diffuseur d'air et une lamelle (10) pouvant être éclairée, comprenant au moins un guide de lumière (18), un premier diffuseur (16) et un corps (12) de lamelle entourant au moins par endroits le guide de lumière (18) et le premier diffuseur (16). Le corps (12) de lamelle présente un orifice de réception s'étendant au moins par endroits sur la longueur de la lamelle (10) et, dans une section de liaison (26) entre les branches (22, 24) du corps (12) de lamelle, au moins une section de sortie de lumière (20) sur la face avant de la lamelle (10). Un premier diffuseur (16) fait d'une matière plastique transparente est introduit dans l'orifice de réception du corps (12) de lamelle, une section de liaison (32) du premier diffuseur (16) étant située entre les branches (28, 30) du premier diffuseur (16) dans la zone de la ou des sections de sortie de lumière (20). Puis un guide de lumière (18) est introduit, lequel est agencé entre les branches (28, 30) du premier diffuseur (16).
