ABSTRACT:
A light emitting diode projection apparatus and method is provided for irradiating a subject with ultraviolet radiation, comprising a plurality of light emitting diodes configured to emit ultraviolet radiation and arranged in a matrix, and a power modulation control unit in communication with the diodes. The power modulation control unit is configured to energize and cause the diodes to emit light and thereby irradiate the subject with ultraviolet radiation sufficient to cause material physical change in the subject.
