US Patent 7305163 Fiber optic phototherapy devices including LED light sources

Fiber optic phototherapy devices include fiber optic light emitters having fiber optic end portions at one or both ends that may be separated into a plurality of groups of end portions that receive light from one or more light emitting diodes (LEDs). The fiber optic end portions of different segments of the light emitters may also be grouped together in different groups and lighted by different LEDs for selectively lighting any or all of the segments of the light emitters at the same or different types as desired. Lenses may be used to focus the light from one or more LEDs onto the end portions of each group. The LEDs may be mounted to a heat sink to dissipate any excess heat generated by the LEDs.
