SOLID STATE LIGHTING USING QUANTUM DOTS IN A LIQUID

摘要

A lighting apparatus that provides general lighting in a region or area intended to be occupied by a person includes a source of light of a first spectral characteristic of sufficient light intensity for the lighting application as well as a reflector or a diffusely reflective chamber or cavity having a transmissive optical passage. An exemplary lighting fixture of the type disclosed herein also includes a liquid containing quantum dots. Various containers, locations and positions for the liquid are disclosed. The quantum dots provide a wavelength shift of at least some light to produce a desired second color characteristic in the light output.
