    Abstract: There is herein described a lighting device including a composite encapsulant and an optical component. The lighting devices include a first interface between the composite encapsulant and a light emitting surface of a light source, and a second interface between the composite encapsulant and the optical component. In various embodiments, the composite encapsulant is configured to increase a critical angle at the first interface, so as to limit total internal reflection at the first interface. Moreover, the properties and/or other features of the composite encapsulant may be controlled to also limit total internal reflection at the second interface. Methods of making such lighting devices are also disclosed.

    Abstract: There is herein described a patterned thin-film wavelength converter (100,200) which comprises a substrate (104) having a first patterned surface with a first pattern, and a thin film (106,206) deposited on the first patterned surface. The thin film consists of a wavelength converting material and has a second patterned surface that is distal from the substrate. The second patterned surface has a second pattern that is substantially the same as the first pattern of the substrate. An advantage of the patterned thin-film wavelength converter is that post-deposition processing is not required to produce a textured surface on the wavelength converting material. A method of making the patterned thin-film wavelength converter is also described.

    Abstract: A wavelength converter for an LED is described that comprises a substrate of monocrystalline garnet having a cubic crystal structure, a first lattice parameter and an oriented crystal face. An epitaxial layer is formed directly on the oriented crystal face of the substrate. The layer is comprised of a monocrystalline garnet phosphor having a cubic crystal structure and a second lattice parameter that is different from the first lattice parameter wherein the difference between the first lattice parameter and the second lattice parameter results in a lattice mismatch within a range of 15%. The strain induced in the phosphor layer by the lattice mismatch shifts the emission of the phosphor to longer wavelengths when a tensile strain is induced and to shorter wavelengths when a compressive strain is induced. Preferably, the wavelength converter is mounted on the light emitting surface of a blue LED to produce an LED light source.

    Abstract: There is herein described a light source comprising a semiconductor device emitting a primary light, a thermally conductive optic having a reflective coating and a wavelength converter having a front surface and a rear surface. The optic is mounted to the rear surface of the wavelength converter and the primary light impinges on the wavelength converter in an emission region. The wavelength converter converts at least a portion of the primary light into a secondary light that is emitted from the front and rear surfaces of the converter and the optic reflects secondary light emitted from the rear surface back into the emission region. The light source may be used in either transmissive or reflective configurations.

    Abstract: Disclosed herein are technologies utilizing sacrificial material layers for producing and transferring wavelength converters for light emitting devices via lift-off. In some embodiments the technologies utilize a precursor in the form of a substrate having a sacrificial layer formed thereon. The sacrificial layer may possess one or more properties that allow it to survive processing of a conversion layer formed thereon, and to facilitate removal of the substrate via a lift off process. In some embodiments the sacrificial layer may be configured to survive relatively high temperature processing without substantially affecting the performance of the conversion layer, and to facilitate removal of the substrate via laser lift off.
