Abstract
The disclosure is directed to glass frits materials containing phosphors that can be used in LED lighting devices and for methods associated therewith for making the phosphor containing frit materials. Suitable non-lead glasses have a composition, in mol %, in the range of 20-24% KO, 8-12% ZnO, 2-6% AlO, 35-41% BOand 22-28 SiO. Suitable leaded glasses have a composition, in wt %, in range of 72-79% PbO, 8-13% AlO, 8-13% BO, 2-5% SiOand 0-0.3% SbO. Commercial high-lead glass can be used in practicing the disclosure. Among the unique advantages are the ability to blend two or more phosphors within the same frit layer which will yield a multi-phosphor-containing glass after firing; the ability to deposit the phosphor onto a substrate into a desired geometric pattern; and the fluorescing layer can be applied to the active plane, with the glass serving as protective substrate.
