Abstract

La présente invention porte sur un guide lumineux avec une optique qui guide la lumière sortant du guide. Le dispositif arrive à une commande précise de la lumière réfléchie par extraction de la lumière d'une zone limitée du guide lumineux. La configuration des réflecteurs utilisés pour l'extraction sélective détermine la nature de la lumière transmise. Les réflecteurs peuvent être situés sur un côté du guide lumineux de façon opposée à un côté de sortie du guide lumineux.
