Abstract
The invention comprises a system and method for treating an exposed tissue of a patient with a light energy. A plurality of light emitting devices are optically coupled with a patients tissue, and apply light treatments to the tissue. A driver circuit and a controller operate to drive the light emitting devices to output different intensities of light treatment to different sub-areas of the tissue being treated.
