Light emission from a light package, such as from an LED light package, is enhanced by a system and method for adjusting the refractive index at the surface of the encapsulating material surrounding the light source. The surface refractive index is changed to better match the index within the encapsulating material with the index of the media surrounding the encapsulating material. In one embodiment, the index is adjusted by roughing the surface of the encapsulating material. In another embodiment, a separate layer is created having a corrective index of refraction. The separate layer can comprise photonic crystals, if desired. In some embodiments the adjusting will achieve a graded index of refraction.

A device and method for emitting output light utilizes multiple light sources to produce original light having different peak wavelengths. A first light source of the device is configured to generate first light having a peak wavelength in the blue wavelength range, while a second light source of the device is configured to generate second light having a peak wavelength in the red wavelength range. Some of the original light emitted from at least the first light source is converted into light having a peak wavelength longer than the peak wavelength of the original light using a photoluminescent material to produce the output light.
