1. A light emitting device, comprising:
a first LED die having a peak emission wavelength L1 in a blue or shorter wavelength;
a second LED die having a peak emission wavelength L2 in a red, orange, yellow, green, or cyan wavelength; and
a homogenous light conversion material positioned to receive light emitted from the first and second LED dies, the light conversion material comprising:
a first phosphor compound having a peak emission wavelength LP1 in a green wavelength;
a second phosphor compound having a peak emission wavelength LP2 in an orange wavelength; and
a third phosphor compound having a peak emission wavelength LP3 in a red, orange, yellow, green, or cyan wavelength;
wherein the light emitting device is a packaged LED device and a relative concentration of the first, second, and third phosphor compounds in the homogenous light conversion material, and a relative luminosity of the first and second LED dies are selected so that the light emitting device, during operation, emits white light having a spectral power distribution satisfying a preference P1 and a fidelity F3 according to a TM-30 standard for color rendering.
