A flexible patch (10) provided with a plurality of light sources (16) mounte d in spaced apart array on its undersurface, and covered with an optically transparent polymer material. The light sources (16) are energized with an electrical current supplied by a flexible polymer battery (44), which is preferably rechargeable. Electrical current is convey ed through a lead (42) that extends from the flexible battery to the flexible patch (10) and then through an electrical circuit that includes a plurality of conductive traces (12, 14) formed using a conductive ink applied to the surface of a flexible substrate that supports the light sources. The thickness of the flexible patch (16) at its maximum is less than 1.0 millimeters. The light sources (16) can be separatly groupe d, the electrical current supplied to each group individually controlled to achieve a desired light intensity, and/or duration exposure to the light therapy over different portions of the undersurface (40) of the flexible patch (10) with different portions of the treatment site.
