Abstract

A light assembly includes a carrier. A first high beam light module is rotatably attached to the carrier for rotation relative to the carrier about a first high beam horizontal axis. A first low beam light module is rotatably attached to the carrier for rotation relative to the carrier about a first low beam horizontal axis. The first high beam horizontal axis and the first low beam horizontal axis are parallel with each other. A bar interconnects the first high beam light module and the first low beam light module. An adjustment drive is coupled to the bar. The adjustment drive is operable to move the bar along a bar axis. Movement of the bar along the bar axis simultaneously rotates the first high beam light module about the first high beam horizontal axis, and the first low beam light module about the first low beam horizontal axis.

Dependent claims

A headlamp assembly for a vehicle, the headlamp assembly comprising:

a carrier;
a first light module rotatably attached to the carrier and rotatable relative to the carrier about a first horizontal axis;
a second light module rotatably attached to the carrier and rotatable relative to the carrier about a second horizontal axis;
wherein the first horizontal axis and the second horizontal axis are parallel with each other;
a main actuator bar interconnecting the first light module and the second light module;
and
an adjustment drive coupled to the main actuator bar and operable to move the main actuator bar along a bar axis to simultaneously rotate the first light module about the first horizontal axis and the second light module about the second horizontal axis;
wherein the carrier includes a plurality of posts, and the main actuator bar includes a plurality of slots extending substantially along the bar axis, with one of the plurality of posts slideably disposed within one of the plurality of slots to slideably support the main actuator bar relative to the carrier and allow movement of the main actuator bar relative to the carrier generally along the bar axis.

A light assembly comprising:

a carrier;
a plurality of first light modules, with each of the plurality of first light modules rotatably attached to the carrier and rotatable relative to the carrier about a respective horizontal module axis;
a plurality of second light modules, with each of the plurality of second light modules rotatably attached to the carrier and rotatable relative to the carrier about a respective horizontal module axis;
wherein the plurality of first light modules and the plurality of second light modules are stacked vertically relative to each other along a vertical rotation axis;
a main actuator bar extending along a bar axis, and interconnecting the plurality of first light modules and the plurality of second light modules;
wherein the main actuator bar includes horizontal threads extending along the bar axis;
an adjustment drive defining annular threads disposed in meshing engagement with the horizontal threads of the main actuator bar, wherein rotation of the adjustment drive about a shaft axis moves the main actuator bar along the bar axis to simultaneously rotate the plurality of first light modules and the plurality of second light modules about their respective horizontal module axis.
