  • Patent number: 11870009
    Abstract: Light-emitting diodes (LEDs), and more particularly edge structures for light shaping in LED chips are disclosed. Edge structures may include a repeating pattern of features that is formed along one or more mesa sidewalls of active LED structure mesas. Such active LED structure mesas may include a p-type layer, an active layer, and at least a portion of an n-type layer. Features of the repeating pattern may be configured with a size and/or shape to promote redirection of laterally propagating light from the active layer at the mesa sidewalls. In this manner, light that may otherwise escape the LED chip at the mesa sidewalls may be redirected toward an intended emission direction for the LED chip. Certain aspects include reflective structures that are provided on the active LED structures mesas and are further arranged to extend past the active LED structure mesas to cover the repeating pattern of features.
