Title
(EN) OPTICAL ASSEMBLY FOR A PROJECTOR AND PROJECTOR COMPRISING SUCH AN OPTICAL ASSEMBLY
(FR) ASSEMBLAGE OPTIQUE POUR UN PROJECTEUR ET PROJECTEUR COMPRENANT UN TEL ASSEMBLAGE OPTIQUE
Abstract
(EN) The present invention relates to an optical assembly for a projector, comprising: - an optical element with a set of lenses, the lenses being suitable for cooperating with a first plurality of light sources, such as LEDs, of said projector, wherein the lenses are suitable for generating primary light beams and are spaced apart from one another by means of inter-lens spaces; - a grating for filling at least part of said inter-lens spaces of the set of lenses, suitable for cooperating with a second plurality of light sources, such as LEDs, of the projector, wherein the grating is suitable for generating a secondary light effect; and - a support element suitable for supporting the set of lenses, at the inter-lens spaces, wherein the grating and the support element are suitable for overlaying by enclosing the optical element between the inner face of the grating and the upper face of the support element and thereby fixing the set of lenses so as to form the optical assembly.
(FR) La présente invention concerne un assemblage optique pour un projecteur, comprenant : - un élément optique avec un ensemble de lentilles, lesdites lentilles étant adaptées pour coopérer avec une première pluralité de sources lumineuses, telles que des DEL, dudit projecteur, dans lequel lesdites lentilles sont adaptées pour générer des faisceaux lumineux primaires et sont espacées les unes des autres à l'aide d'espaces inter-lentilles, - une grille pour remplir au moins une partie desdits espaces inter- lentilles dudit ensemble de lentilles, adaptée pour coopérer avec une deuxième pluralité de sources lumineuses, telles que des DEL, dudit projecteur, dans lequel ladite grille est adaptée pour générer un effet lumineux secondaire, et - un élément de support, adapté pour supporter l'ensemble de lentilles, au niveau des espaces inter-lentilles, dans lequel la grille et l'élément de support sont adaptés pour se superposer en enfermant l'élément optique entre la face intérieure de la grille et la face supérieure de l'élément de support et fixer ainsi l'ensemble de lentilles afin de former l'assemblage optique.
