Abstract: A photoluminescence material paste comprises: a first inorganic photoluminescence material having a first density, a second inorganic photoluminescence material having a second density and a light transmissive non-curable silicone fluid that is not curable by itself. The first density of the first inorganic photoluminescence material is different from the second density of the second inorganic photoluminescence material. The first and second inorganic photoluminescence materials are substantially homogenously distributed within the light transmissive non-curable silicone fluid to form the photoluminescence material paste. 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%.
