Abstract
Light emitting devices for light emitting diodes (LEDs) are disclosed. In one embodiment a light emitting device can include a submount and a light emission area disposed over the submount. The light emission area can include one or more light emitting diodes (LEDs), a fillet at least partially disposed about the one or more the LEDs, and filling material. The filling material can be disposed over a portion of the one or more LEDs and a portion of the fillet.
Claims52
A light emitting device, comprising:
- a submount comprising a planar surface;
- a light emission area disposed over the submount, wherein the light emission area comprises at least one light emitting diode (LED);
- and
- a fillet at least partially disposed about the light emission area, wherein the fillet and the at least one LED are each disposed along the planar surface of the submount.
