ABSTRACT:
A machine for producing multiple beams of light from a single beam of light having at least one light beam source, device to direct the light beam source upon a single or multiple faced rotating reflective or refractive surface which then sweeps the beam repeatedly outward with an annular displacement of 360 degrees or less, and a plate containing openings which is disposed so as to intercept the rotating reflected beam and allow light to pass only through the openings in the plate effectively reshaping the angularly displaced beam into multiple beams. A control system is provided which may be incorporated into the machine, if desired, which uses shutter device and an electronic control system for selection and recall of beams produced by the machine. Reflective or refractive surfaces are provided inside the machine which direct the produced beams to a convenient position. Three embodiments are described including a version which produces multiple beams which emanate from the machine in an orderly row, a version which may be mounted overhead and produces beams in a 360 degree displacement, and a version which rests upon a table.
