Abstract

L'invention porte sur un procédé de fabrication d'un guide de lumière à écran diffusant intégré, comprenant la réalisation (E1) d'un moule et la mise en œuvre d'un processus de bi-injection de matériaux plastiques distincts dans ledit moule, ledit processus de bi-injection comprenant : - une première phase d'injection (E2) d'un premier matériau plastique présentant des caractéristiques optiques adaptées pour former un guide de lumière, et, après un temps prédéterminé de refroidissement du premier matériau plastique injecté, - une deuxième phase d'injection (E3) d'un deuxième matériau plastique présentant des caractéristiques optiques adaptées pour former un écran diffusant pour couvrir au moins partiellement le guide de lumière. L'invention vise aussi un dispositif d'éclairage d'ambiance comportant une pièce monobloc formant un guide de lumière à écran diffusant intégré.The invention relates to a method for manufacturing a light guide with integrated diffusing screen, comprising the production (E1) of a mold and the implementation of a process of bi-injection of separate plastic materials into said mold. , said bi-injection process comprising: - a first injection phase (E2) of a first plastic material having optical characteristics suitable for forming a light guide, and, after a predetermined time for cooling the first plastic material injected , - a second injection phase (E3) of a second plastic material having optical characteristics adapted to form a diffusing screen to cover at least partially the light guide. The invention also relates to an ambient lighting device comprising a single piece forming a light guide with an integrated diffusing screen.
