Abstract: A device and method of operation are disclosed which provide an improved light source. The device and its mode of operation serve to substantially reduce the energy required to produce sufficient light for normal human vision. A mechanical embodiment of the device serves to concentrate the total output of a light source into one or more relatively small beams, then sweep the beams of light around or over an area to be illuminated for vision. Alternatively, an electrical approach can be employed to achieve substantially the same results as the mechanical approach. Because the light emitted by the light source is concentrated within one or more relatively small beams, the intermittent lighting effect of which is undetectable by the human eye, a significant reduction in energy consumption can be achieved in that a lower-powered light source can be employed to achieve an illumination level which is comparable to that of a much higher-powered light source.
