A light emission device comprising a light emitting element, a wavelength conversion (e.g. phosphor) element, and a filter that reduces Color over Angle (CoA) effects by at least partially reflecting light from the light emitting element that strike the filter at near-normal angles of incidence. In some embodiments, a combined phosphor and filter layer is formed over the LED die. The filter may comprise a dispersion of self-aligning moieties, such as dielectric platelets in a film that is vacuum laminated to the LED structure. Xirallic&#xae; Galaxy Blue pigment, comprising an aluminum oxide core coated on both sides with thin films of SnO, and TiO, and Ronastar&#xae; Blue, comprising Calcium Aluminum Borosilicate and TiOmay provide the dielectric platelets.
