Light therapy modality

摘要

A method of light therapy includes non-invasive, intra-cranial administration of bright light via the ear canal of a subject by using a light intensity of 0.7-12 lumens, and a treatment time of 1-15 minutes. A medical device including radiation elements for directing the light via the ear canal for use in the light therapy is described.

主权项

1. A medical device for treating a subject for depression, the medical device comprising:
radiation means for directing light directly into an ear canal of the subject suffering from depression, the radiation means including at least one phosphorus-based white light emitting diode (“LED”) having a primary peak wavelength in the range of 450-475 nm and a secondary peak wavelength in the range of 495-570 nm; adapter means for arranging the radiation means in an external ear of the subject to enable administration of light via the ear canal; and a controller unit for adjusting bright light administration and optical radiation provided to the ear canal by the radiation means.
