The invention relates to a projection unit (491, 492, 493) of or for a vehicle (48), comprising: a light source (12); a reflective microdisplay (32) for reflecting the light emitted by the light source (12); a first lens unit (14) for collecting light emitted by the light source (12) along a first axis (A1); a reflector (28) for guiding the light collected by the first lens unit (14) along a second axis (A2) to a reflective microdisplay (32); a second lens unit (38) for collecting the light reflected by the reflective microdisplay (32) and for guiding the collected light to the projection surface (42) wherein the reflective microdisplay (32) is arranged inside the projection unit (491, 492, 493), the reflective microdisplay (32) being rotated by a rotation angle (alpha) such that the row direction (DR) and/or the column direction (DC) is inclined with respect to the first axis (A1). Furthermore, the invention relates to a vehicle component (44) and/or a vehicle (48) comprising such a projection unit (491, 492, 493).
本发明涉及一种车辆(48)的或用于车辆(48)的投影单元(491、492、493),包括:光源(12);反射式微显示器(32),反射式微显示器用于反射由光源(12)发射的光;第一透镜单元(14),第一透镜单元用于沿着第一轴线(A1)收集由光源(12)发射的光;反射器(28),反射器用于沿着第二轴线(A2)将由第一透镜单元(14)收集的光引导到反射式微显示器(32);第二透镜单元(38),第二透镜单元(38)用于收集由反射式微显示器(32)反射的光并用于将所收集的光引导到投影表面(42),其中反射式微显示器(32)布置在投影单元(491、492、493)内部,反射式微显示器(32)旋转了一旋转角度(α),使得行方向(DR)和/或列方向(DC)相对于第一轴线(A1)倾斜。此外,本发明涉及包括这种投影单元(491、492、493)的车辆部件(44)和/或车辆(48)。
