Abstract: Infrared heating panels are provided with an electrically insulative substrate that carries one or more infrared heating elements. Each heating element includes an elongated first segment attached to a first surface of the substrate and an elongated second segment electrically connected in series with the first segment. At least the first segment is a strip of an electrically resistive material adapted to emit infrared radiation in response to a current. The second segment is attached to the second surface of the substrate opposite from and in a parallel arrangement with the first segment such that a first current flowing through the heating element flows through the first segment in a first direction relative to the substrate and flows through the second segment in a second direction opposite the first direction. Saunas, heating systems, and methods for reducing electromagnetic emissions in an infrared sauna are also provided.

Abstract: A far infrared panel for humid and dry environments includes a frame, a thin layer, a grounding circuit board, a cloth layer and a second layer. The thin layer includes a carbon membrane and a printed circuit board. Two wires are used to connect the carbon membrane with a control device. The grounding circuit board includes a grounding layer, a circuit board and a wire. The wire is used to connect the grounding circuit board with the ground. The second layer which has a crisscross pattern and a plurality of fixing devices are used to fixedly hold the thin layer, grounding circuit board and cloth layer in the frame. Therefore, the far infrared panel of the present invention may be used to raise the temperature of a sauna room swiftly and evenly and then can make users to sweat heavily.
