Abstract

La présente invention se rapporte à une unité optique (1) comprenant : - un premier collimateur destiné à recevoir un premier faisceau lumineux émis par une première source de lumière ; - un deuxième collimateur (21) destiné à recevoir un deuxième faisceau lumineux (F2) émis par une deuxième source de lumière ; - un organe de coupure (3) ; - un système de projection (4) ; Selon l'invention, l'organe de coupure (3) est agencé de manière à arrêter ou réfléchir les rayons l'atteignant d'un côté ou de l'autre. Le premier collimateur est agencé de manière à envoyer le premier faisceau lumineux d'un côté de l'organe de coupure tandis que le deuxième collimateur (21) est agencé de manière envoyer le deuxième faisceau lumineux (F2), des deux côtés de l'organe de coupure. En outre, le système de projection (4), le premier collimateur, le deuxième collimateur (21) et l'organe de coupure (3) sont agencés de manière à projeter le premier faisceau (F1) en un faisceau à coupure et à projeter le deuxième faisceau (F2) en un faisceau sans coupure.The present invention relates to an optical unit (1) comprising: - a first collimator intended to receive a first light beam emitted by a first light source; - a second collimator (21) intended to receive a second light beam (F2) emitted by a second light source; - a switching device (3); - a projection system (4); According to the invention, the cut-off member (3) is arranged so as to stop or reflect the rays reaching it from one side or the other. The first collimator is arranged to send the first light beam to one side of the cut-off device while the second collimator (21) is arranged to send the second light beam (F2) to both sides of the switch. breaking device. Further, the projection system (4), the first collimator, the second collimator (21) and the cutoff member (3) are arranged to project the first beam (F1) into a cutoff beam and to project the second beam (F2) in a beam without cutoff.
