Abstract
A light therapy system and method are provided for treating humans or terrestrial or aquatic animal and plant subjects with non-coherent light. The system includes an electrical controller configured with two supplies of voltage, high and low frequency pulse-width-modulators, adjustable high and low frequency duty cycle controllers for controlling the duty cycle outputs of the respective high and low frequency pulse-width-modulators that determine light pulsation intensities, and at least one light source electrically connected to the electrical controller and having at least two distinct light emitting elements. One light emitting element operates at high light pulsation frequencies, and another light emitting element operates at low light pulsation frequencies. The light may include a plurality of the high frequency powered light emitting elements and a plurality of the low frequency powered light emitting elements.
