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.
