Disclosed is a portable phototherapy device capable of emitting electromagnetic radiation of a wavelength and intensity sufficient to obtain a desired phototherapeutic effect to a subject, without being in direct physical contact with said subject. The device is portable, capable of being flattened, folded, rolled, compressed, or otherwise collapsed, to a size smaller than that of its operating size. The device may be of any size or shape, and may optionally comprise a frame support. The device may be powered by a variety of sources, including one or more batteries. The device may be configured to deliver electromagnetic radiation sufficient to obtain one or more of a variety of desired phototherapeutic effects.

1. A portable phototherapy device adapted for the treatment of hyperbilirubinemia, comprising: (a) a floor section essentially rectangular in shape defined by a head end and a foot end and two sides, said floor being dimensioned so as to support the length of a reclining infant of up to about five kilograms, said floor having a fold-over tab attached along at least a portion of one side of the floor, the tab exhibiting one or more fasteners along its length;(b) a canopy section attached to said floor section along the side of the floor section opposite said fold-over tab, said canopy section extending from a proximal end attached to said floor section to a distal edge, said canopy section exhibiting one or more fasteners near its distal edge capable of mating with the corresponding fasteners on said fold-over tab to securely but reversibly join said distal edge of the canopy section to said fold-over tab, said canopy section being dimensioned such that joining said distal edge of the canopy section with the fold-over tab attached to said floor section forms an arcuate shell over said floor section, defining an assembled configuration having an inner surface facing said floor section and an outer surface;(c) a plurality of light sources affixed to the inner surface of said shell, said plurality of light sources being capable of emitting light of a wavelength of 400-550 nm;(d) an electrical power source;(e) circuitry operably connecting said power source to said plurality of light sources; and(f) one or more frame support elements affixed to said canopy section which are flexible yet rigid enough to support said canopy section in an arcuate shell configuration; wherein the inner surface of said shell comprises a reflective surface; and wherein said floor section, fold-over tab, and canopy sections are of a pliable material such that, when said fasteners are not fastened, said floor section, tab, and canopy section, together with said affixed plurality of light sources and frame support elements are, capable of being flattened or rolled or compressed to a disassembled size smaller than that of its operating size, and wherein, in the assembled configuration, said plurality of light sources is capable of transmitting light of sufficient intensity and wavelength to provide a desired phototherapeutic effect to an infant positioned on the floor section without said plurality of light sources of said device being in direct physical contact with said infant. 2. The portable phototherapy device of claim 1, wherein said floor section and said canopy section comprise a cloth layer. 3. The portable phototherapy device of claim 1, wherein said floor section is detachably attached to said canopy section. 4. The portable phototherapy device of claim 3, wherein said plurality of light sources are distributed throughout the inner surface of said shell. 5. The portable phototherapy device of claim 4, wherein said plurality of light sources are LED's. 6. The portable phototherapy device of claim 5, wherein said LED's are capable of emitting blue light. 7. The portable phototherapy device of claim 6, wherein said light source is capable of emitting light of a wavelength of about 450 nm to about 470 nm. 8. The portable phototherapy device of claim 1, wherein said power source is not line power. 9. The portable phototherapy device of claim 8, wherein said power source is a battery. 10. The portable phototherapy device of claim 9, wherein said battery is rechargeable. 11. The portable phototherapy device of claim 10, wherein said battery is a 12 volt battery. 12. The portable phototherapy device of claim 8, wherein power source is photovoltaic. 13. The portable phototherapy device of claim 1, wherein said circuitry comprises electrical wire. 14. The portable phototherapy device of claim 13, wherein said circuitry further comprises an on/off switch. 15. The portable phototherapy device of claim 1, wherein said frame support comprises one or more frame supports selected from the group consisting of poles, rods, tubes, slats, springs, and wire. 16. The portable phototherapy device of claim 15, wherein said frame support comprises one or more slats. 17. The portable phototherapy device of claim 15, wherein said frame support is detachably attached to said canopy section. 18. A method for treating a subject with a phototherapy device comprising: (a) providing a phototherapy device according to any of the phototherapy devices of claims 1 to 17,(b) positioning an infant in need of phototherapy on the floor of said device such that said infant is exposed to light emitting from said plurality of light sources, and(c) maintaining said exposure for a sufficient duration to achieve a desired phototherapeutic effect in said infant. 19. The portable phototherapy device of claim 15, wherein said frame support is non-detachably attached to said canopy section. 20. The portable phototherapy device of claim 15, wherein said frame support comprises one or more tubes, wherein said one or more tubes is capable of being flattened or compressed to a size that is less than the working space of the assembled and operational phototherapy device.
