    Abstract: Solid state light emitting apparatuses include blue LEDs (including but not limited to a combination of short wavelength and long wavelength blue LEDs) to stimulate green lumiphors, with supplemental emissions by either red lumiphors and/or red solid state light emitters, to provide aggregate emissions with high S/P ratio (e.g., at least 1.95) and favorably high color rendering values (e.g., 85 or greater), preferably in combination with high brightness and high luminous efficacy. In certain embodiments, a solid state light emitting apparatus may be devoid of a LED having a peak wavelength of from 470-599 nm and/or devoid of lumiphors peak wavelengths in the yellow range. Multiple LEDs may be arranged in an emitter package.

    Abstract: The present disclosure is directed to LED components, methods and systems using such components, having light emitter devices with emissions tuned to meet CRI and LER goal values at a defined CCT. These emitter devices and methods may use a combination of light emitting diodes and quantum dots to tune the emission to meet these criteria. The quantum dots may incorporate additional features to protect the quantum dots from environmental conditions and improve heat dissipation, such as coatings and thermally conductive features.

    Abstract: Solid state light emitting apparatuses include blue LEDs (e.g., including short wavelength and long wavelength blue LEDs in combination) to stimulate green lumiphors, with supplemental emissions by red lumiphors and/or red solid state light emitters, to provide aggregate emissions with high S/P ratio (e.g., ≧1.95) and high color rendering values (e.g., ≧85), preferably in combination with high brightness and high luminous efficacy. In certain embodiments, a light emitting apparatus may be devoid of a LED having a peak wavelength of from 470-599 nm and/or devoid of lumiphors with peak wavelengths in the yellow range. Multiple LEDs may be arranged in an emitter package. A fabrication method includes mounting multiple solid state emitters (e.g., with a first blue and a second red emitter) to a common substrate, applying a stencil or mask over the second emitter, applying a lumiphoric material over the first emitter, and removing the stencil or mask.
