    摘要: There is herein described a patterned thin-film wavelength converter which comprises a substrate having a first patterned surface with a first pattern, and a thin film 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.

    摘要: 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.

    摘要: 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.
