发明名称 Low profile highly efficient vehicular LED modules and headlamps
摘要 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.

主权项 1. A vehicle headlamp module, comprising: a lens having canted input surface including a plurality of near-field lens elements, an exit surface and a cavity between the surfaces; and an LED light source positioned to direct incident light through the input surface, wherein the elements are configured to shape the light from the input surface into a collimated light pattern emanating from the exit surface containing at least 60% of the incident light.
