Patent ID: 6974224

Claim:
A method of illuminating an animal's body, the method comprising: positioning a light delivery module adjacent to a selected component of an animal's body, the module having first and second light delivery elements that can each be activated to intermittently illuminate the body component with light having at least two wavelengths; exposing the body component to light from the first light delivery element of the light delivery module, the first element having a first selected range of wavelengths and a second selected range of wavelengths that does not substantially overlap the first range, for a first selected exposure time interval, and allowing light received in this first time interval to produce at least one free electron within or adjacent to the body component; exposing the body component to light from the second light delivery element of the light delivery module, the second element having a third selected range of wavelengths and a fourth selected range of wavelengths that does not substantially overlap the third range, for a second selected exposure time interval, and allowing light received in this second time interval to produce at least one free electron within or adjacent to the body component, where the first and second exposure time intervals are spaced apart by a dark time interval having a selected length Δt(dark) that is at least about 0.1 sec; and allowing the at least one free electron produced during each of the first and second exposure time intervals to come to equilibrium with the body adjacent to or within the body component.
