    • A vehicle headlamp module is provided that includes a lens having a plurality of near-field lens elements, a canted input surface, an exit surface and a cavity between the surfaces. The headlamp module also includes an LED lighting module that directs incident light through the input and exit surfaces. The lens elements are configured to transmit from the exit surface a collimated light pattern containing at least 60% of the incident light. In some embodiments, the exit surface includes a step-wise pattern of optical elements. In other implementations, a headlamp assembly is provided that includes a plurality of vehicle headlamp modules. Each headlamp module includes: a lens with a canted input surface and an exit surface, a bezel surrounding the lens, and an LED light source that directs incident light through the input surface. The lens of each module includes a plurality of near-field lens elements.
    • 提供一种车辆前照灯模块,其包括具有多个近场透镜元件的透镜,倾斜输入表面,出射表面和表面之间的空腔。 前照灯模块还包括将入射光引导通过输入和出射表面的LED照明模块。 透镜元件被配置为从出射表面发射包含至少60%的入射光的准直光图案。 在一些实施例中,出射表面包括光学元件的逐步图案。 在其他实施方式中,提供了包括多个车辆前照灯模块的头灯组件。 每个头灯模块包括:具有倾斜输入表面和出射表面的透镜,围绕透镜的边框,以及引导入射光通过输入表面的LED光源。 每个模块的透镜包括多个近场透镜元件。
