MODULAR HEADLAMP ASSEMBLY FOR PRODUCING A LIGHT DISTRIBUTION PATTERN

摘要

A modular headlamp assembly includes low beam headlamp module for providing illumination in a predetermined light distribution pattern. The low beam headlamp module includes a low beam heat sink and mounting assembly having a low beam heat sink portion with first and second sides. A low beam reflector member is attached to the low beam heat sink and mounting assembly such that the low beam heat sink portion bisects the reflector low beam member into first and second segments. A plurality of LED light sources is supported by the low beam heat sink portion. The reflector assembly and plurality of LED light sources produce a light distribution pattern extending at least 40 degrees in a first horizontal direction and at least 40 degrees in a second horizontal direction, with the light distribution pattern having a sharp horizontal cutoff line parallel to and below a horizon.
