Light emitting devices for light emitting diodes (LEDS)

1. A light emitting device, comprising:

a submount comprising at least one of a dielectric layer, a core layer, a solder mask layer and one or more reflection layer;

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 comprises a substantially horizontal surface disposed against the reflection layer and the fillet further comprises a substantially vertical surface disposed against at least one or more of the dielectric layer and the solder mask layer.

2. The light emitting device of claim 1 , wherein a right angle is formed at an intersection of the substantially horizontal and the substantially vertical surfaces of the fillet, and the fillet comprises a curved upper surface.

3. The light emitting device of claim 2 , wherein the curved upper surface of the fillet is concave.

4. The light emitting device of claim 1 , further comprising retention material at least partially disposed about the light emission area and above a portion of the submount.

5. The light emitting device of claim 1 , wherein the reflection layer is disposed between the core layer and a portion of the light emission area.

6. The light emitting device of claim 1 , further comprising a filling material disposed over a portion of the light emission area and the fillet.

7. The light emitting device of claim 1 , wherein the fillet and the at least one LED are each disposed along a planar surface of the submount.
