    Abstract: A light emitting diode (LED) lighting apparatus including an array of first optic elements overlying an array of LED chips, wherein each of the LED chips is configured to emit light of a first wavelength range through a light emitting surface of the overlying first optic element. The array of first optic elements are also underlying an array of second optic elements, wherein each of the second optic elements is configured to convert light of the first wavelength range to be emitted through the light emitting surface of the underlying first optic element to light of a second wavelength range different from the first wavelength range.

    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.
