Abstract
A method and apparatus for the multi-dimensional control of a light source's brightest point over a targeted area is disclosed. Control and drive electronics are presented to the beam-steering device causing the beam-steering component to steer the spot of light toward a targeted area in at least a two-dimensional scanning pattern about a vertical and horizontal axis. The result is an illuminated pattern displayed on a targeted area that appears to be a solid, uniformly illuminated light pattern, having the intensity of a spot beam and the area of a broad beam.
