Patent ID: 8676044

Claim:
A sauna comprising: an enclosure assembly for accommodating a user; at least one infrared emitter coupled with the enclosure assembly and operable to emit infrared radiation over at least two different specified wavelength-ranges in the infrared-wavelength spectrum, wherein each specified wavelength-range comprises one of near-infrared radiation, mid-infrared radiation, and far-infrared radiation; wherein the at least one infrared emitter comprises at least one heating element selected from, at least one array of LEDs, an element containing ceramic particles with a nanometer scale dimension, a carbon-containing planar heating element and a heating element on a polyimide film substrate; and at least one driver module coupled to the at least one infrared emitter and operable to control the at least one infrared emitter to emit infrared radiation over one of the at least two specified wavelength-ranges in the infrared wavelength spectrum, wherein a heat control module operably coupled to the at least one driver module and operable to allow a user to fixedly specify desired output infrared radiation over the wavelength-range associated with each of the at least one infrared emitter.
