Abstract:
1. A light therapy appliance, comprising: a battery; one or more Light Emitting Diodes (LEDs) configured to emit at least two different colored lights at different associated wavelengths; a hand held portable enclosure configured to enclose the battery and the one or more LEDs and sized to be held in a palm of a hand; a lens configured to direct the at least two different colored lights emitted from the one or more LEDs; and a sleeve configured to reflect and direct the light emitted from the LEDs out through a front end of the enclosure; wherein the lens includes a continuous smooth front face to allow the application of the at least two different colored lights directly to skin; and wherein the enclosure includes top and bottom circular surfaces and a round outer edge configured to extend around lateral sides and back end of the enclosure between the top and bottom circular surfaces; wherein the lens curves outwardly only along a front end of the enclosure; wherein the one or more LEDs are positioned substantially orthogonally to the lens; and wherein the sleeve is configured to surround the one or more LEDs and extend between a circuit board that holds the one or more LEDs and the lens so that substantially all of the light emitted from the one or more LEDs is directed through the sleeve out through the lens.
