Abstract
Official abstract text for this publication.
A solid state lighting device including a light source capable of emitting white light including a blue spectral component and having a deficiency in a spectral region, and an optical component that is positioned to receive at least a portion of the light generated by the light source, the optical component comprising an optical material for converting at least a portion of the blue spectral component of the light to one or more predetermined wavelengths such that light emitted by the solid state lighting device includes light emission from the light source supplemented with light emission at one or more predetermined wavelengths, wherein the optical material comprises quantum confined semiconductor nanoparticles. Also disclosed is lighting fixture, a cover plate for a lighting fixture and a method.
First claim
Opening claim text (preview).
The invention claimed is: 1. A solid state lighting device comprising a phosphor converted LED light source that emits white light including a blue spectral component and having a deficiency in at least one spectral region, and an optical component that is positioned to receive at least a portion of the white light generated by the light source and supplement the spectrum of the white light passing through the optical component, the optical component comprising an optical material…
