Abstract

- L'objet de l'invention est un procédé de masquage sélectif d'un guide de lumière en matière polymère transparente pourvu de parties de diffusion de lumière consistant à déposer de l'encre sur une ou plusieurs zones localisées du guide de lumière pour masquer lesdites une ou plusieurs zones et les rendre inaptes à diffuser de la lumière. L'invention concerne en outre un guide de lumière pourvu de parties de diffusion qui comporte des zones masquées au moyen du procédé de l'une quelconque des revendications précédentes.The object of the invention is a method of selective masking of a light guide made of transparent polymer material provided with light scattering parts consisting in depositing ink on one or more localized areas of the light guide in order to mask said one or more areas and make them unsuitable for diffusing light. The invention further relates to a light guide provided with diffusing portions which has areas masked by the method of any one of the preceding claims.
