Patent ID: 7888691

Claim:
A structure comprising: a semiconductor light emitting device 34 comprising a light emitting layer disposed between an n-type region and a p-type region, wherein the light emitting layer is adapted to emit first light having a first peak wavelength; a first wavelength converting material 38 adapted to absorb the first light and emit second light having a second peak wavelength; a second wavelength converting material 36 adapted to absorb one of the first light and the second light and emit third light having a third peak wavelength; wherein the first and second wavelength converting materials are disposed in a path of light emitted by the semiconductor light emitting device; and a filter 40 adapted to reflect fourth light having a fourth peak wavelength and transmit light having a peak wavelength longer or shorter than the fourth peak wavelength, wherein the fourth light comprises one of a portion of the second light and a portion of the third light, and wherein the filter is disposed in the path of at least a portion of the first, second, and third light.
