US Patent 11402081 Adjustable lighting device

A lighting device assembly includes a light source attached to a heat sink member to emit light in a first direction. A support structure supports the heat sink member in a pivotally adjustable orientation about an adjustment axis, to allow adjustment of the first direction. A drive mechanism selectively drives the heat sink member to pivotally adjust the orientation of the heat sink member about the adjustment axis to change the first direction. The drive mechanism includes a drive screw having, a collar threaded to the drive screw to move linearly along the drive screw axis as the drive screw is rotated, and at least one strut to transfer linear movement of the collar to pivotal movement of the heat sink member.
