The invention relates to the technical field of carpet lamps, in particular to a vehicle carpet lamp, a vehicle carpet lamp system assembly and a design method. The vehicle carpet lamp comprises: an LED light source, which is used for emitting illumination light beams; a light beam adjusting mechanism, which is used for adjusting the illumination light beams into parallel light beams; a pattern array light-transmitting sheet, which comprises a light-transmitting surface provided with a plurality of sub-patterns which are distributed in an array, wherein the light-transmitting surface is perpendicular to the propagation direction of the parallel light beams; and a fly-eye len, wherein the light inlet surface of the fly-eye lens is perpendicular to the propagation direction of the parallel light beams, the light outlet surface of the fly-eye lens is provided with sub-lenses in one-to-one correspondence with the sub-patterns, and each sub-lens can amplify the corresponding sub-pattern and project the sub-pattern to a target projection area on the projection surface of the fly-eye lens, so that the sub-pattern and the target projection area converge together to form a set pattern. According to the invention, a mode of shielding projection imaging is adopted, and the precision and scale requirements on the sub-patterns of the pattern array light-transmitting sheet are reduced, so that the array projection of the sub-patterns on the pattern array light-transmitting sheet is realized at low cost.

    本发明涉及地毯灯技术领域,具体涉及一种车辆地毯灯、车辆地毯灯系统组件和设计方法。该车辆地毯灯中,LED光源,用于发出照明光束;光束调整机构,用于将照明光束调整为平行光束;图案阵列透光片,包括设有呈阵列分布的若干个的子图案的透光面;其中,透光面垂直于平行光束的传播方向;复眼透镜,其进光面垂直于平行光束的传播方向,其出光面上设置有与子图案一一对应的子透镜;每个子透镜能够将其对应的子图案放大并投影至复眼透镜的投影面上的目标投影区域,共同会聚为设定图案。本发明采用遮挡投影成像的方式,降低了对于图案阵列透光片的子图案的精度和尺度要求,从而低成本地实现了图案阵列透光片上的子图案的阵列投影。
