US 8,556,490 B1 · Systems, methods and devices for providing quantum dot lighting solutions

Abstract

A light module for providing an array of quantum dot disks and methods for manufacturing the same are described herein. The light module may include at least one light emitting diode (LED) light source in an edge lighting configuration emitting light into a waveguide, such as a frustrated total internal reflection (FTIR) waveguide. At least a portion of the waveguide includes a nanophosphor material, such as a quantum dot disk. Moreover, the waveguide includes at least one aperture on a surface of the waveguide optically aligned with the nanophosphor material. The light module further includes a lens optically aligned with the aperture of the waveguide, such as an over-optic. In alternative embodiments of the invention, the light module may includes at least one LED light source optically aligned with a quantum dot disk remotely located from the LED light source and optically aligned with an over-optic lens.
