Abstract
Light-emitting diode (LED) packages and more particularly LED packages with directional emission intensity and color uniformity are disclosed. LED packages include one or more LED chips on a submount with arrangements of light-altering materials and lumiphoric material layers that provide directional light emissions with improved color over angle uniformity. Light-altering materials are provided that cover sidewalls of LED chips while lumiphoric material layers cover LED chips and light-altering materials. Such LED packages may avoid the need to include encapsulation materials and/or lenses that would otherwise cover the lumiphoric material layers. As such, exterior light-exiting faces of LED packages are formed by surfaces of lumiphoric material layers.
