用于车辆的照明装置
摘要：
本发明涉及一种用于车辆的照明装置，该照明装置包括通过透明的遮盖片封闭的壳体，在该壳体中设置有包含至少一个第一光源和第二光源(3、3'、3”)的光源单元，并且在该壳体中设置有包含用于产生全息发光图像的全息元件(8)的光学单元，其中，所述光学单元具有至少一个遮光元件(9、9'、9”)，以用于限制光源(3、3'、3”)的发射角度范围 所述光学单元具有配设给第一光源(3、3'、3”)的第一光学构件(7、7'、7”)和配设给第二光源(3、3'、3”)的第二光学构件(7、7'、7”)，利用所述第一光学构件和第二光学构件能使由光源(3、3'、3”)发射的光(10、10'、10”)朝全息元件(8)方向偏转，在各光学构件(7、7'、7”)之间的过渡区域(12)中，遮隔元件(13、13')这样伸出，使得阻止由第一光源(3)发射的、不入射到所配设的第一光学构件(7)上的散射光(15)入射到相邻的第二光学构件(7')上，并且反过来阻止由第二光源(3')发射的、不入射到第二光学构件(7')上的散射光(15')入射到第一光学构件(7)上。
摘要（英）：

The invention relates to a lighting device for vehicles, said lighting device having a housing which is closed by a transparent cover pane and in which there are a light source unit, containing at least one first and one second light source (3, 3', 3''), and an optical unit, containing a hologram element (8) for generating a holographic luminous image. The optical unit has at least one screen element (9, 9', 9'') for limiting an emission angle range (Phi) of the light source (3, 3', 3''). The optical unit has a first optical component (7, 7', 7'') associated with the first light source (3, 3',3'') and a second optical component (7, 7', 7'') associated with the second light source (3, 3', 3''), with which components light (10, 10', 10'') emitted by the light sources (3, 3', 3'') can be deflected in the direction of the hologram element (8). In a transition region (12) between the optical components (7, 7', 7''), a shielding element (13, 13') protrudes such that scattered light (15) which is emitted by the first light source (3) and does not impinge on the associated first optical component (7) is prevented from impinging on the adjacent second optical component (7') and, conversely, that scattered light (15') which is emitted by the second light source (3') and does not impinge on the second optical component (7') is prevented from impinging on the first optical component (7).
