Claim 18:
19. A light emitting device comprising:
a plurality of first LEDs and first phosphors configured to emit a red spectral component light having a red color point;
a plurality of second LEDs and second phosphors configured to emit a blue spectral component light having a blue color point, the second LEDs and second phosphors separate from the first LEDs and first phosphors;
a plurality of third LEDs and a third phosphors configured to emit a green spectral component light having a green color point, the third LEDs and third phosphors separate from the first and second LEDs and first and second phosphors, each third phosphor comprising a green phosphor having a peak wavelength between 500 nm and 580 nm and a red phosphor having a peak wavelength greater than 630 nm; and
a controller configured to independently control an input power for the first LEDs, the second LEDs and the third LEDs,
the red spectral component light, the blue spectral component light, and the green spectral component light combine to form a composite white light.
