The invention discloses a liquid crystal projection lamp for a vehicle and the vehicle. The projection lamp comprises a driving module, an imaging lens module, an input lens module, a light source and a lamp shell (5), the driving module comprises a driving board (11) and a liquid crystal screen (12), and the driving board (11) is used for sending projection data received from the vehicle control unit to the liquid crystal screen (12); the liquid crystal screen (12) is used for displaying a projection image corresponding to the projection data; the imaging lens module is used for amplifying the projection image and outputting the amplified projection image; the light source can be turned on and/or turned off in response to a control instruction of the driving board (11); the input lens module is arranged between the light source and the imaging lens module, and the liquid crystal screen (12) is arranged between the input lens module and the imaging lens module; the driving module, the imaging lens module and the input lens module are all contained in the lamp shell (5), and a limiting structure matched with the driving module, the imaging lens module and the input lens module is arranged in the lamp shell (5). Compared with a DPL projection device, the liquid crystal projection lamp for the vehicle is low in cost and reliable in performance.

    一种车用液晶投影灯及车辆,投影灯包括驱动模块、成像镜头模块、输入镜头模块、光源和灯壳(5);驱动模块包括驱动板(11)和液晶屏(12),驱动板(11)用于将从整车控制器接收到的投影数据发送给液晶屏(12);液晶屏(12)用于显示投影数据对应的投影图像;成像镜头模组用于放大投影图像并输出放大后的投影图像;光源能够响应于驱动板(11)的控制指令点亮和/或关闭;输入镜头模块设置在光源与成像镜头模块之间,液晶屏(12)设置在输入镜头模块与成像镜头模块之间;驱动模块、成像镜头模块和输入镜头模块均容置于灯壳(5)内,灯壳(5)内设置有与驱动模块、成像镜头模块和输入镜头模块相匹配的限位结构。车用液晶投影灯与DPL投影装置相比成本低、性能可靠。
