Claim Text:
1. A photoluminescence material paste comprising: a first inorganic photoluminescence material having a first density, a second inorganic photoluminescence material having a second density, wherein the first density of the first inorganic photoluminescence material is different from the second density of the second inorganic photoluminescence material, a light transmissive non-curable silicone fluid, wherein the first inorganic photoluminescence material and the second inorganic photoluminescence material are substantially homogenously distributed within the light transmissive silicone fluid to form the photoluminescence material paste, wherein a weight loading of the first and second photoluminescence materials in the photoluminescence material paste is in a range of about 60% to about 95%, and wherein the non-curable silicone fluid is not curable by itself and is not curable when mixed with another material and wherein the non-curable silicone fluid comprises polyphenylmethylsiloxane.
