US Patent 7438719 Phototherapy system and device

A phototherapy system and device is disclosed, including an array of light sources from at least two distinct spectral light regions. The first spectral light region represents the treatment color, and thus is chosen for its phototherapeutic value. For instance, blue light may be the treatment color for hyperbilirubinemia. The second spectral light region represents the balancing color, and is chosen for its ability to mitigate discomfort that may be caused by viewing the treatment color. When blue is the treatment color, yellow has been found to be an effective balancing color.
