Abstract: A portable light delivery device for delivering light to the blood supply of a human body through a nonocular area of skin on the body includes an attachment member, a portable light delivery unit connected to the attachment member and a portable power supply. The portable light delivery unit provides one or more wavelengths of light within a specifically determined range of intensity and a specifically determined angle of illumination. A portable control unit may be included on the light delivery device for selectively controlling the light delivery unit. A programming device associated with the control unit selectively changes the programming of the controller. The light delivery device is portably secured to a region of the body having a substantial amount of blood vessels near the surface thereof to deliver light to the blood supply of the body for treating mood disorders, seasonal affective disorder and disorders involving circadian rhythm and sleep.

Abstract: A device is provided for delivering light to the blood supply of a human body through a non-ocular skin area. The device has a plurality of light emitting diodes (LEDs) spaced apart from each other and extending through apertures for emitting light to the body and a power supply connected to the light delivery unit. The device provides wavelengths of light within a specifically-determined range of intensity and a specifically-determined angles of illumination. Devices may be included for controlling and programming the output of the LEDs. A method is provided for delivering light to a non-ocular body region for treating jaundice, breaking down bilirubin and treating other disorders.
