Abstract
An infrared radiant panel is formed by overlaid substrates having conductors thereon which are electrically activated to generate heat to cause infrared radiation of desired wavelengths. The conductors are arranged to cancel magnetic fields caused by current flow therethrough. A conductive shield further suppresses fields generated by the panel.
Claims18
A low EMF radiant infrared panel comprising:
- (a) at least one nonconductive substrate;
- (b) a first infrared region of the infrared panel formed in a first region of the at least one nonconductive substrate to radiate infrared energy in a first range of wavelengths and a second infrared region of the infrared panel formed in a second region of the at least one nonconductive substrate to radiate infrared energy in a second range of wavelengths, each of the first and second infrared regions including:
- (1) a first conductor formed on a first substrate surface of the at least one nonconductive substrate in a selected pattern;
- (2) a second conductor formed on a second substrate surface of the at least one nonconductive substrate in the selected pattern, the second conductor being positioned in close adjacent relation to the first conductor and being aligned therewith;
- (3) the first and second conductors receiving a level of current required to generate heat to cause infrared radiation in a range of wavelengths associated with the respective infrared region;
- and
- (4) the first and second conductors being electrically activated in opposite polarities to cause cancellation of first components of electromagnetic fields resulting from currents flowing in the first and second conductors;
- (c) a conductive electromagnetic shield layer positioned in covering relation to the first and second infrared regions to suppress second electromagnetic field components resulting from currents flowing through the first and second conductors;
- and
- (d) each of the first and second conductors being a bifilar conductor which extends on its respective substrate surface in a pattern in which a first segment of each of the respective first and second conductors is positioned in closely adjacent, parallel relation with a second segment of the respective first and second conductors along the respective first and second conductors such that current flows in opposite directions in the first and second segments to thereby cause cancellation of components of electromagnetic fields generated by currents flowing in the segments.

A low EMF radiant infrared panel comprising:
- (a) a plurality of nonconductive substrates, each substrate having opposite substrate surfaces;
- (b) a first infrared region and a second infrared region formed on a surface of a first nonconductive substrate to radiate infrared energy respectively in a first range and a second range of wavelengths and on a surface of a second nonconductive substrate to radiate infrared energy in the first and second ranges of wavelengths, each of the infrared regions including:
- (1) a first conductor formed on a surface of a first nonconductive substrate in a selected pattern;
- and
- (2) a second conductor formed on a surface of a second nonconductive substrate in the selected pattern;
- (c) the substrates being joined in mutually overlaying relation to position the first conductor in closely adjacent aligned relation to the second conductor;
- (d) the first and second conductors receiving levels of current required to generate heat to cause infrared radiation in a range of wavelengths associated with the respective infrared region;
- (e) the first and second conductors being electrically activated in opposite polarities to cause cancellation of components of electromagnetic fields resulting from currents flowing in the conductors;
- (f) a conductive electromagnetic shield layer positioned in covering relation to the first and second infrared regions to suppress additional electromagnetic field components resulting from currents flowing through conductors thereof;
- and
- (g) each of the first and second conductors being a bifilar conductor which extends on its respective substrate surface in a pattern in which a first segment of each first and second conductor is positioned in closely adjacent, parallel relation with a second segment of the respective first and second conductors along the respective first and second conductors such that current flows in opposite directions in the first and second segments to thereby cause cancellation of components of electromagnetic fields generated by currents flowing in the segments.
