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.
