Abstract:
Packaged semiconductor light emitting device are provided including a reflector having a lower sidewall portion defining a reflective cavity. A light emitting device is positioned in the reflective cavity. A first quantity of cured encapsulant material having a first index of refraction is provided in the reflective cavity including the light emitting device. A second quantity of cured encapsulant material having a second index of refraction, different from the first index of refraction, is provided on the first quantity of cured encapsulant material. The first and second index of refraction are selected to provide a buried lens in the reflective cavity.
