Abstract

La présente invention se rapporte à un ensemble optique (1) destiné à former un faisceau présentant une ligne de coupure. L’ensemble optique (1) comprenant: une première pièce optique (2) en matériau transparent comprenant : des guides de lumière comprenant chacun un dioptre d’entrée et une sortie élémentaire ; une sortie commune située en aval des sorties élémentaires; une première face s’étendant entre les sorties élémentaires et la sortie commune, cette première face étant délimitée en aval par un bord de coupure ; un matériau réfléchissant (5) distinct du matériau de la première pièce optique (2) et disposé en face de la première face de la première pièce optique (2), le matériau réfléchissant (5) s’étendant depuis le bord de coupure vers les sorties élémentaires ; Selon l’invention, le matériau réfléchissant (5) et la première pièce optique (2) étant agencés de manière à se retenir l’un à l’autre sans pièce supplémentaire et de manière à ce que le matériau réfléchissant (5) soit en contact direct avec le bord de coupure.Figure pour l’abrégé : figure 2The present invention relates to an optical assembly (1) intended to form a beam having a cut-off line. The optical assembly (1) comprising: a first optical part (2) made of transparent material comprising: light guides each comprising an input diopter and an elementary output; a common output located downstream of the elementary outputs; a first face extending between the elementary outputs and the common output, this first face being delimited downstream by a cut-off edge; a reflective material (5) distinct from the material of the first optical part (2) and placed opposite the first face of the first optical part (2), the reflective material (5) extending from the cut-off edge towards the elementary outputs; According to the invention, the reflecting material (5) and the first optical part (2) being arranged in such a way as to be held together without an additional part and in such a way that the reflecting material (5) is in direct contact with the cut edge.Figure for abstract: Figure 2
