Abstract
A vehicle lighting module is provided that includes a lens having a plurality of near-field lens elements, an input surface, and an exit surface. The lighting module also includes an LED light source that directs incident light through the input surface and out of the exit surface. The plurality of lens elements is configured to transmit from the exit surface a collimated light pattern containing at least 60% of the incident light. Further, a vehicle headlamp assembly is provided that includes a plurality of vehicle lighting modules, each module comprising a lens, and an LED light source that directs incident light through the lens. The assembly further includes a case for housing the lighting modules. The lens includes a plurality of lens elements configured to transmit at least 60% of the incident light in a collimated, vehicular light pattern.
