Claim Text:
1. A white light illumination system comprising a multi-chip excitation source and a phosphor package, the multi-chip excitation source comprising: a first radiation source for providing UV co-excitation radiation to the phosphor package, the first radiation source emitting in wavelengths ranging from about 250 nm to about 410 nm; a second radiation source for providing blue co-excitation radiation to the phosphor package, the second radiation source emitting in wavelengths ranging from about 410 nm to about 480 nm; and a phosphor package configured to emit photoluminescence in wavelengths ranging from about 440 nm to about 700 nm upon co-excitation from the first and second radiation sources, wherein the phosphor package includes a green emitting aluminate-based phosphor; wherein the phosphor package further including a red emitting phosphor, the red emitting phosphor comprises a nitride-based red phosphor; and the nitride-based red phosphor is of a general formula M
