Claim 14:
15. A light emitting device comprising:
a first LED and a first phosphor configured to emit a red spectral component light having a red color point;
a second LED and a second phosphor configured to emit a blue spectral component light having a blue color point, the second LED and second phosphor separate from the first LED and first phosphor;
a third LED and a third phosphor configured to emit a green spectral component light having a green color point, the third LED and third phosphor separate from the first and second LEDs and first and second phosphors, the 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 LED, the second LED and the third LED,
the red spectral component light, the blue spectral component light, and the green spectral component light combine to form a composite white light.
