1. A therapeutic light source for treating a target tissue with a therapeutic light energy having a therapeutic light power density, the source comprising:

  • a plurality of LEDs, each LED transmitting divergent light, the LEDs distributed across a first region, the divergent light across the first region having a first total light power density less than the therapeutic light energy; and

    an optical train optically coupling the LEDs with the target tissue, the optical train combining the divergent light and delivering the divergent light within a second region smaller than the first region so that the delivered divergent light has the therapeutic light power density.
