Abstract

Apparatus and methods for lighting. The apparatus may include a beam-angle changing lens. The beam-angle changing lens may be movable from a first position in front of a slotted cylinder to a second position in front of the slotted cylinder. The slotted cylinder may be fixed with respect to translation along the central axis. The slotted cylinder may be configured to move the beam-angle changing lens from the first position to the second position when the slotted cylinder is rotated. The slotted cylinder may be configured to displace the support to move the lens to the positions. The apparatus may include a guide pin. Rotation of the slotted cylinder may displace the guide pin linearly in a direction parallel to the axis. Motion of the guide pin may move the lens. The apparatus may include a rotatable shaft. The rotatable shaft may be configured to rotate the slotted cylinder.
