Abstract
A light emitting apparatus is disclosed for medical applications including photo-dynamic-therapy (PDT), photobiostimulation (photobiomodulation), photo-sterilization, and photo-curing. The light emitting apparatus comprises a plurality of semiconductor light emitting elements, preferably light emitting diodes (LEDs) to produce a high intensity light beam, and a liquid light guide for delivering the light beam from the light source to the treatment site.
Claims5
A light emitting apparatus for performing medical treatment, including but not limited to photobiostimulation (photobiomodulation), photo-dynamic-therapy (PDT), photo-sterilization, and photo-curing on a targeted site, the light emitting apparatus comprising:
- an array of high power light emitting diodes (LEDs) to produce a light beam with high light intensity;
- and
- a liquid light guide having a proximal end positioned in a path of the light beam to collect and deliver the light beam to a distal end of the light guide and output the light beam to the targeted site;
- wherein the liquid light guide has an acceptance angle and core diameter comparable to the divergence angle and size of the light beam to achieve a high light coupling efficiency.
