发明名称 Lighting system with variable shaped beam
摘要 A lens for use in a light fixture provided to project a beam of light in a first light pattern having a first cross-sectional geometry. A lenticular lens element is supported in the fixture and movable into a position to interrupt the beam of light for selecting beam shape by altering the first projected light pattern from the first cross-sectional geometry to a second cross-sectional geometry different from the first geometry and for moving the second pattern to a desired orientation. The lens element may be carried by a disc rotatably mounted in the fixture. The disc may carry a plurality of lens elements which can also change the orientation of the projected light patterns.
