Abstract: Solid-state lighting devices including light-emitting diodes (LEDs), and more particularly packaged LED devices are disclosed. LED packages are disclosed herein with arrangements of LED chips and corresponding lumiphoric regions that are configured to provide overall light emissions having improved color mixing and emission uniformity. LED packages are further disclosed herein that are configured to be tunable between different colors or correlated color temperatures (CCTs) while providing improved color mixing and emission uniformity. Arrangements may include differing lumiphoric regions that are arranged with various alternating patterns including one or more intersecting lines, rows of alternating lumiphoric regions, patterns that alternate in at least two directions, and checkerboard patterns.

Abstract: A light emitting device includes a light emitting diode (“LED”) that emits light having a dominant wavelength in the blue color range, and a recipient luminophoric medium that is configured to down-convert at least some of the light emitted by the LED. The recipient luminophoric medium includes a green phosphor that down-converts the radiation emitted by the LED to radiation having a peak wavelength that is between about 525 nanometers and about 550 nanometers, a yellow phosphor having a wavelength peak that is between about 550 nanometers and about 580 nanometers, and a red (Ca1-x-ySrxEu2+y)SiAlN3 phosphor. The (Ca1-x-ySrxEu2+y)SiAlN3 phosphor has a europium content y of between about 0.003 and 0.009 and a strontium content x of between about 0.150 and 0.300.
