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.
