Abstract
Light-emitting devices including solid-state light-emitting devices, light-emitting diode (LED) devices, and LED packages with support elements for improved near-field and far-field emissions are disclosed. LED chips may be mounted to support elements in a manner that directs light through the support elements in desired emission directions. Support elements include optical structures that spread and mix light laterally within the support element. Optical structures include various light-altering layers, such as light-diffusing layers or light-reflective layers, that are arranged to effectively increase internal reflections for lateral spreading of light. Patterned arrangements of light-altering layers include portions that mask direct emissions for LED chips, thereby redistributing emissions laterally to increase near-field and/or far-field uniformity across an increased portion of emitting surfaces. Support elements as described may be well suited for low profile LED devices where device heights are less than or equal to device widths.
