Abstract
Light emitting diode (LED) apparatuses and methods having a high lumen output density. An example apparatus can include a substrate with one or more LEDs enclosed by an encapsulant. The encapsulant comprises beveled edges and/or top surface facets. By providing facets in the encapsulant and minimizing the chip-to-area ratio through efficient via placement, a high lumen density is achieved. Facets and bevels can be created by removing material from the encapsulant with a beveled blade.
