Abstract
A light emitting device includes a LED having a light emitting first surface and a light emitting second surface that define a corner. A support layer is disposed to receive light emitted by the light emitting second surface and is disposed adjacent the corner. A luminophoric medium layer at least partially covers the light emitting first surface and the light emitting second surface where the luminophoric medium layer is at least partially supported by the support layer to prevent a narrowing of the luminophoric medium layer.
Claims20
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.
A light emitting device, comprising:
- a body;
- a light emitting diode (LED) mounted on the body, the LED having a light emitting first surface and a light emitting second surface defining a corner therebetween, and a light emitting top surface;
- a support layer disposed to receive light emitted by the light emitting second surface and disposed adjacent the corner, the support layer having a perimeter on the body, the perimeter comprising a transition that curves proximate the corner, and wherein the support layer extends at least partially over the light emitting top surface;
- and
- a luminophoric medium layer at least partially covering the light emitting first surface and the light emitting second surface, the luminophoric medium layer being at least partially supported by the support layer.
