Patent attributes
An electronic lighting apparatus with at least one multiple position adjustable lighting pod. Each lighting pod includes at least one variable intensity light source and a proximity sensor for detecting objects interposed between the lighting pod and a work field. Each variable intensity light source is powered by a controllable pulse width modulated power supply or other suitable power supply which can be utilized to vary the intensity of the light source. In response to detection of an object interposed between a particular lighting pod and the work surface, the power to that lighting pod is increased, increasing the illumination of the work field. Alternatively, power to that lighting pod may be decreased and power to alternate lighting pods is increased, thereby minimizing shadows within the work field.
