1. A light emitting device, comprising:
a light emitting diode (LED) having a light emitting first side surface and a light emitting second side surface defining a corner therebetween, and a light emitting top surface;
a luminophoric medium layer directly on the light emitting top surface and at least partially covering the corner; and
a support layer disposed between the corner and the luminophoric medium layer, a perimeter of the support layer comprising a transition area that curves from a position proximate the light emitting first side surface to another position proximate the light emitting second side surface, the transition area separating the luminophoric medium layer from the corner, and wherein the support layer extends at least partially over the light emitting top surface.
