Abstract
A transformative wavelength conversion medium is provided, comprising: a phosphor; and, a curable liquid component, wherein the curable liquid component, comprises: an aliphatic resin component, wherein the aliphatic resin component has an average of at least two epoxide groups per molecule; and, a curing agent; wherein the curable liquid component contains less than 0.5 wt % of monoepoxide molecules (based on the total weight of the aliphatic resin component); wherein the curable liquid component contains 1 to 90 wt % of polyepoxide molecules containing at least three epoxide groups per molecule (based on the total weight of the aliphatic resin component); and, wherein the curable liquid component is a liquid at 25° C. and atmospheric pressure; wherein the phosphor is dispersed in the curable liquid component.
