Abstract
A lighting system is disclosed. The lighting system comprises at least one light source comprising a light emitting diode (LED) and one or more phosphors optically coupled to the LED to convert at least a portion of original light emitted by the LED to provide a modified LED light having a first predetermined spectral output, and an optical material that is optically coupled to at least a portion of a surface of a light guide plate and optically coupled to receive at least a portion of the modified LED light and to convert at least a portion of the modified LED light to at least one predetermined wavelength to provide modified light having a second predetermined spectral output, wherein the optical material comprises one or more types of quantum confined semiconductor nanoparticle. A device including a lighting system is also disclosed.
