An adjustment mechanism for directional recessed luminaires includes a tilt adjustment screw 104 and rotation adjustment screw 124 supported in adjacent positions on a bearing ring 102, the screws being oriented vertically and conveniently accessible through an open center of the bearing ring. Follower 106 travels vertically on the tilt adjustment screw when rotated. Drive link 108 connected to both the follower and a four bar linkage (110), transfers force from the follower to the linkage when the tilt screw is rotated. The linkage pivots about anchor points 114,116 and is pivotally connected to lamp carrier frame 118 supporting light source 105. When the tilt adjustment screw is rotated, light source moves along a path (FIG. 6, 7) to aim the light beam. After aiming, the mechanism locks the light source into place. The mechanism is compact and the adjustment screws are easily accessible from beneath the mechanism. |

1. An adjustment mechanism for a directional recessed luminaire, comprising:
a tilt adjustment screw supported on a bearing ring of a directional recessed luminaire, the tilt adjustment screw being oriented in a vertical direction and accessible for rotation by a tool inserted through an open center of the bearing ring, the tilt adjustment screw being configured to adjust a vertical tilt of a lamp carrier frame supported on the bearing ring, to vertically lift or lower a direction of light from a light source in the lamp carrier frame, with respect to an area to be illuminated by the light source; and a rotation adjustment screw supported in an adjacent position to the tilt adjustment screw on the bearing ring, the rotation adjustment screw being oriented in the vertical direction and accessible for rotation by the tool inserted through the open center of the bearing ring, the rotation adjustment screw being configured to adjust a horizontal angle orientation of the lamp carrier frame by rotating the bearing ring, to horizontally rotate the direction of light from the light source, with respect to the area to be illuminated. |
