ABSTRACT:
A light emitting device comprised of a light emitting diode on a mounting surface, the light emitting diode includes a substrate layer and at least one active region. A resilient substantially transparent and substantially phosphor free polymer layer extends from the mounting surface to above at least one quarter of a height of the substrate layer but below a top surface of the light emitting diode. A second phosphor containing layer extends from the phosphor free polymer layer to above the top surface of the light emitting diode.
