Abstract[English]
The present invention relates to the technical field of projection, and in particular to a projection lens system. The system comprises projection lenses, a light splitting device, and a lens assembly I; the lens assembly I forms a primary image plane which is guided to different emergent light paths by means of the light splitting device; and the projection lenses are respectively arranged on the emergent light paths. The present invention can realize multi-screen and multi-directional projection display under the condition that a single light valve is shared, and the projections of various directions are relatively independent, so that the projections of different directions can be conveniently and flexibly adjusted; the structure is compact; and the occupied space is small.[French]
La présente invention se rapporte au domaine technique de la projection, et elle concerne en particulier un système de lentilles de projection. Le système comprend des lentilles de projection, un dispositif de division de lumière et un ensemble lentille I ; l'ensemble lentille I forme un plan d'image principal qui est guidé vers différents trajets de lumière émergente au moyen du dispositif de division de lumière ; et les lentilles de projection sont respectivement disposées sur les trajets de lumière émergente. La présente invention peut réaliser un affichage par projection multi-écran et multidirectionnel à condition qu'un seul modulateur de lumière soit partagé, et les projections de diverses directions sont relativement indépendantes, ce qui permet de les ajuster de manière commode et flexible ; la structure est compacte ; et peu d'espace est occupé.[Chinese]
本发明涉及投影技术领域，尤其涉及一种投影镜头系统，包括投射镜头、分光装置和镜头组件一，镜头组件一形成一次像面并通过分光装置和引导至不同的出射光路，各出射光路上分别设置投射镜头。本发明在共用单个光阀的情况下能实现多屏多方位的投影显示，各方位的投影相对独立，能方便的对不同方位的投影进行灵活调整，结构紧凑、占用空间小。
