Patent Number: 5980066 
Title: Lighting System with Multiple Beam Shapes 
Abstract: Overlapping lenses for use in a light fixture provided to project a beam of light in a first beam shape having a first cross-sectional geometry. A first lens device 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 beam shape from the first cross-sectional geometry to a second cross-sectional geometry different from the first geometry. The first lens device includes at least one lenticular lens element having lens lenticules oriented in a first direction. A second lens device, separate from the first device, is supported in the fixture and movable into a position to interrupt the beam of light for selecting beam shape by altering the second projected beam shape from the second cross-sectional geometry to a third cross-sectional geometry different from the first and second geometries. The second lens device includes another lenticular lens element overlapping the one lenticular lens element of the first lens device and has lenticules oriented in a second direction, different from the first direction. The lens elements may be carried by discs rotatably mounted in the fixture. Each disc may carry a plurality of lens elements which can be combined by overlapping to change beam angle and beam shape.
