A device includes a LED die having a peak emission at a blue or shorter wavelength, a LED die having a peak emission at a red, orange, yellow, green, or cyan wavelength, and a homogenous light conversion material positioned to receive light emitted from the LED dies. The light conversion material including: (i) a first phosphor compound having a peak emission at a green wavelength; (ii) a second phosphor compound having a peak emission at an orange wavelength; and (iii) a third phosphor compound having a peak emission at a red, orange, yellow, green, or cyan wavelength. The device is a packaged LED device and a relative concentration of the phosphor compounds and a relative luminosity of the LED dies are selected so the device emits white light satisfying a preference P1 and a fidelity F3 according to a TM-30 standard for color rendering.
A light emitting device, comprising:
11-13. (canceled)
A light emitting device package comprising a first light emitting device according to any one of the previous claims, wherein the relative concentration of the first, second, and third phosphor compounds in the homogenous light conversion material, and the relative luminosity of the first and second LEDs are further selected so that the light emitting device, during operation, emits first white light having a first correlated color temperature (CCT);
