More Information
Summary:A lighting device comprises a planar array of LEDs comprising a set of parallel LED strips and an optical sheet extending over and parallel to the plane of the array of LEDs. The optical sheet comprises an interleaved pattern of parallel optical strips and pass through strips and it is movable relative to the array of LEDs to create different output beam characteristics.
