Abstract
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). Lenses may be used to focus the light from one or more LEDs onto the end portions. The LEDs may be mounted to a heat sink to dissipate any excess heat generated by the LEDs.
Claims17
A phototherapy device for phototherapy treatment of a patient comprising a light emitter for emitting light, the light emitter comprising one or more layers of optical fibers, the optical fibers having end portions extending from at least one end of the light emitter, the end portions being tightly secured together, and at least one light emitting diode (LED) for focusing light on the end portions for transmission of the light to the light emitter for emission therefrom, wherein the at least one LED is inside a housing and is mounted to a heat sink attached to a back side of the housing to dissipate any excess heat generated by the at least one LED inside the housing.
A phototherapy device for phototherapy treatment of a patient comprising a light emitter for emitting light, the light emitter comprising one or more layers of optical fibers, the optical fibers having end portions extending from at least one end of the light emitter, the end portions being tightly secured together, a plurality of light emitting diodes (LEDs) inside a housing for focusing light on the end portions for transmission of the light to the light emitter for emission therefrom, and a single multi-faceted lens inside the housing in close proximity to two or more LEDs for focusing light from the two or more LEDs onto the end portions.
A phototherapy device for phototherapy treatment of a patient comprising a light emitter for emitting light, the light emitter comprising one or more layers of optical fibers, the optical fibers having end portions extending from at least one end of the light emitter, the end portions being tightly secured together, and at least one light emitting diode (LED) for focusing light on the end portions for transmission of the light to the light emitter for emission therefrom, the LED being mounted to a heat sink, and means for increasing the amount of power to a plurality of LEDs in response to a decrease in the light output from the LEDs to maintain a substantially constant light output from the LEDs.
A phototherapy device for phototherapy treatment of a patient comprising a light emitter for emitting light, the light emitter comprising one or more layers of optical fibers, the optical fibers having end portions extending from at least one end of the light emitter, the end portions being tightly secured together, and at least one light emitting diode (LED) for focusing light on the end portions for transmission of the light to the light emitter for emission therefrom, the LED being mounted to a heat sink, and a preprogrammed power curve based on an average life curve of a plurality of LEDs that is used to increase the power to the LEDs as the LEDs age over time.
