Claim 0:
1. A method of manufacturing a white light emitting device, comprising the steps of:
providing first and second LEDs operable to generate excitation light having a dominant wavelength in a range from 440 nm to 480 nm;
providing a first photoluminescence material which generates light having a peak emission wavelength in a range from 500 nm to 590 nm;
providing a second photoluminescence material which generates light having a peak emission wavelength in a range from 600 nm to 650 nm;
disposing the second photoluminescence material over and into direct contact with the second LED; and
disposing the first photoluminescence material over the first and second LEDs.
