ABSTRACT:
A pattern change mechanism is provided for use with a lighting fixture. The mechanism includes a plurality of blocking members for blocking light directed by the reflector of the lighting fixture toward a target surface, means for moving the blocking members to achieve small, medium and large patterns of light on the target surface. The moving means includes a rotation member, drive means, actuator means linked to the blocking members and a handle for rotating the rotation member to thereby effect movement of the blocking members through the drive means and actuator means.
