System and method for treating exposed tissue with light emitting diodes

摘要

The invention comprises a system and method for treating an exposed tissue of a patient with a light energy. A plurality of light emitting diodes are disposed over an area of a supporting structure. The light emitting diodes emit light energy. The light energy comprises a substantial band of wavelengths between about 380 and 800 nm. The light emitting diodes are optically coupled to the exposed tissue of the patient. A driver circuit is electrically coupled to the light emitting diodes for driving a current through the plurality of light emitting diodes. An average irradiance of the light energy emitted from the area by the light emitting diodes is at least about 30 mW per square centimeter during a treatment. In some embodiments, the light energy emitted from a first light emitting diode substantially overlaps with light energy emitted from several adjacent light emitting diodes as the light energy propagates toward the tissue. A substantially uniform irradiance profile distribution forms near a surface of the tissue.
