Patent ID: 8764259

Claim:
A lighting assembly comprising a semiconductor light source; a support with a recess, within which recess the semiconductor light source is positioned; a collimator comprising a light entry opening; a light exit opening; and at least one side wall, wherein the collimator is moveable, relative to the support, within a range of motion about an axis of rotation, wherein the collimator is attached to the support such that the light entry opening of the collimator and the recess are joined in a nested manner so that light emitted by the semiconductor light source within the recess enters the collimator through the light entry opening and exits essentially only through the light exit opening of the collimator for any position of the collimator over the range of motion, wherein the recess and the light entry opening of the collimator comprises an essentially rectangular cross-section, and a collimator apron shaped to extend outwards along at least one edge of the light entry opening; and an actuator for moving the collimator about the axis of rotation, wherein the axis of rotation of the collimator is parallel to an edge of the light entry opening; a collimator comprising: a light entry opening; an apron shaped to extend outwards along at least one edge of the light entry opening; a light exit opening; and at least one side wall, wherein the collimator is moveable, relative to the support, within a range of motion about an axis of rotation, wherein the collimator is attached to the support such that the light entry opening of the collimator and the recess are joined in a nested manner so that light emitted by the semiconductor light source within the recess enters the collimator through the light entry opening and exits essentially only through the light exit opening of the collimator for any position of the collimator over the range of motion; and an actuator for moving the collimator about the axis of rotation, wherein the axis of rotation of the collimator is parallel to an edge of the recess; wherein the actuator comprises a rod connected to the edge of the light entry opening opposite the apron, which rod is rotatable about the axis of rotation to tilt the collimator about the axis of rotation.
