Methods and apparatus for light therapy

1. An apparatus for use in light therapy comprising:

at least one light emitting diode array adapted to emit a wavelength of light;

a targeting mechanism coupled to the at least one light emitting diode array so as to allow light emitted from the at least one light emitting diode array to be repeatably positioned on a target area during non-contact light therapy;

an imaging mechanism adapted to record an image of a target area,

wherein the targeting mechanism is coupled to the imaging mechanism and includes at least one targeting light source, the at least one targeting light source adapted to allow the imaging mechanism to be repeatably positioned on a target area prior to image recording during each of a plurality of different non-contact light therapy treatments so as to provide clinically repeatable dosages sufficient to have a therapeutic effect, and

wherein the apparatus further comprises a sequencer mechanism having:

a first position in which the at least one targeting light source is off and the imaging mechanism does not record an image;

a second position in which the targeting light source is on and the imaging mechanism does not record an image; and

a third position in which the targeting light source is off and the imaging mechanism records an image.

2. The apparatus of claim 1 wherein the at least one light emitting diode array comprises a plurality of light emitting diode arrays, each light emitting diode array adapted to emit a different wavelength of light.

3. The apparatus of claim 2 wherein each light emitting diode array includes a plurality of light emitting diodes and wherein light emitting diodes that emit different wavelengths are uniformly interdispersed.
