초록 ▼

Described herein are devices, systems, and methods for delivering phototherapy to a subject. A phototherapy light engine is combined with other components to form a phototherapy system that provides phototherapy treatment to a subject. A phototherapy system may be implemented as a hand held system c

대표청구항 ▼

1. A phototherapy light engine comprising: a. a thermally conductive core substrate having a first and a second surface;b. a plurality of light emitting diodes (LEDs) for emitting light comprising phototherapeutic component wavelengths, the plurality of LEDs configured to couple with said first surface of said thermally conductive core substrate, said thermally conductive core substrate for absorbing heat from said plurality of LEDs;c. a plurality of light reflectors functionally coupled to said plurality of LEDs for reflecting said emitted light, thereby directing said light toward a skin surface for treatment of a phototherapy subject;d. a window positioned to cover at least part of said first surface of said thermally conductive core substrate;e. a collar coupled to said first surface of said thermally conductive core substrate, said collar adapted to engage the skin surface and to limit escape of the emitted light from the skin surface and a surrounding area, wherein said collar is coupled to one or more sensors that cause the device to enable phototherapy when the collar is in contact with the skin surface of the phototherapy subject; andf. a heat sink coupled to said second surface of said thermally conductive core substrate, wherein said heat sink is configured and adapted to conduct heat away from said thermally conductive core substrate;wherein one or more of said plurality of light reflectors is positioned on the interior surface of the collar at the perimeter of the plurality of LEDs, and surrounds the plurality of LEDs. 2. The phototherapy light engine of claim 1, wherein said thermally conductive core substrate comprises aluminum. 3. The phototherapy light engine of claim 1, wherein said heat sink is functionally coupled to a fan. 4. The phototherapy light engine of claim 1, wherein said heat sink is functionally coupled to a thermally conductive enclosure. 5. The phototherapy light engine of claim 1, further comprising a plurality of contact pads coupled to at least one of said plurality of LEDs and to said first surface of said thermally conductive metal core substrate, for conducting heat from said plurality of said LEDs to said thermally conductive core substrate, said plurality of contact pads having an area that is larger than an area of at least one of the LEDs. 6. The phototherapy light engine of claim 1, wherein said plurality of LEDs comprises one or more bare die LEDs. 7. The phototherapy light engine of claim 6, further comprising a plurality of optically transmissive covers in direct contact with said bare die LEDs without an air gap therebetween, for reducing optical losses from internal refraction between said bare die LEDs and air. 8. The phototherapy light engine of claim 1, wherein said plurality of LEDs emit light in a therapeutic range comprising a UVB frequency range. 9. The phototherapy light engine of claim 8, wherein said UVB frequency range is about 300-320 nanometers. 10. The phototherapy light engine of claim 1, wherein one of said plurality of reflectors is cone shaped and is positioned and configured to reflect light emitted from exactly one of said plurality of LEDs. 11. The phototherapy light engine of claim 1, wherein said plurality of light reflectors comprise an aluminum reflector surface for reflecting the emitted light toward the skin surface. 12. The phototherapy light engine of claim 1, further comprising a housing configured for housing at least one of said thermally conductive core substrate, said heat sink, said plurality of LEDs, said plurality of light reflectors, said window and said collar. 13. The phototherapy light engine of claim 12, wherein said window is positioned within said housing so that a portion of a sidewall of said housing extends beyond said position of said window. 14. The phototherapy light engine of claim 1, wherein said window is adapted to filter some of the emitted light to block and/or attenuate light in certain wavelengths. 15. The phototherapy light engine of claim 13, wherein said portion of said sidewall of said housing that extends beyond said position of said window is coupled to a reflective surface for reflecting light inward and toward the skin surface. 16. The phototherapy light engine of claim 1, wherein said collar comprises a soft bio-compatible material.
