Patent ID: 8724054

Claim:
A spectral conversion device comprising: a plurality of discrete units, the plurality of discrete units including transparent discrete units and dyed discrete units, wherein the dyed discrete units are dyed with a photoluminescent material at a concentration greater than or equal to an amount sufficient to absorb and convert substantially all input light from a light source to a desired output spectrum; and a coating material disposed around the plurality of discrete units, wherein the coating material binds the plurality of discrete units to form a matrix, further wherein a thickness of the coating material determines the distance between each of the plurality of discrete units; wherein when the plurality of discrete units are positioned over the light source, the input light passing through the transparent discrete units is not converted, and the input light passing through the dyed discrete units is converted, further wherein the emitted input light and the converted input light correspond to the desired output spectrum to produce one or more colors.
