Lighting apparatus with electronic shadow compensation
First Claim
1. An improved lighting apparatus comprising:
- a plurality of variable intensity lighting pods, each lighting pod focused on a work field and disposed along a radius extending from the work field;
a proximity sensor within each lighting pod for detecting objects interposed between the light pod and the work field; and
a power control circuit coupled to each lighting pod and each proximity sensor for varying the light intensity of particular variable intensity lighting pods in response to objects interposed between selected lighting pods and the work field by decreasing the light intensity of each lighting pod having an object interposed between that lighting pod and the work field such that shadows within the work field are minimized.

Abstract
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.
