Abstract: A wavelength converting layer is disclosed that includes a plurality of phosphor grains 50-500 nm in size and encapsulated in cerium free YAG shells and a binder material binding the plurality of phosphor grains, the wavelength converting layer having a thickness of 5-20 microns attached to the light emitting surface.

Abstract: A first component with a first sidewall and a second component with a second sidewall may be mounted onto an expandable film such that an original distance X is the distance between the first sidewall and the second sidewall. The expandable film may be expanded such that an expanded distance Y is the distance between the first sidewall and the second sidewall and expanded distance Y is greater than original distance X. A first sidewall material may be applied within at least a part of a space between the first sidewall and the second sidewall. The expandable film may be expanded such that a contracted distance Z is the distance between the first sidewall and the second sidewall, and contracted distance Z is less than expanded distance Y.

Abstract: An optical isolation material may be applied to walls of a first cavity and a second cavity in a wafer mesh. A wavelength converting layer may be deposited into the first cavity to create a first segment and into the second cavity to create a second segment. The first segment may be attached to a first light emitting device to create a first pixel and the second segment to a second light emitting device to create a second pixel. The wafer mesh may be removed.

Abstract: A wavelength converting layer is partially diced to generate a first and second wavelength converting layer segment and to allow partial isolation between the first segment and the second segment such that the wavelength converting layer segments are connected by a connecting wavelength converting layer. The first and second wavelength converting layer segments are attached to a first and second light emitting device, respectively to create a first and second pixel. The connecting wavelength converting layer segment is removed to allow complete isolation between the first pixel and the second pixel. An optical isolation material is applied to exposed surfaces of the first and second pixel and a sacrificial portion of the wavelength converting layer segments and optical isolation material attached to the sacrificial portion is removed from a surface facing away from the first light emitting device, to expose a emitting surface of the first wavelength converting layer segment.

Abstract: In a method according to embodiments of the invention, for a predetermined amount of light produced by a light emitting diode and converted by a phosphor layer comprising a host material and a dopant, and for a predetermined maximum reduction in efficiency of the phosphor at increasing excitation density, a maximum dopant concentration of the phosphor layer is selected.

Abstract: 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® Galaxy Blue pigment, comprising an aluminum oxide core coated on both sides with thin films of SnO2, and TiO2, and Ronastar® Blue, comprising Calcium Aluminum Borosilicate and TiO2 may provide the dielectric platelets.
