US Patent 11054090 High gamut index solid-state white light emitting devices

A white light emitting device includes a solid-state excitation source operable to generate excitation light having a dominant wavelength ranging from 440 nm to 455 nm; a first photoluminescence material which generates light having a peak emission wavelength ranging from 500 nm to 530 nm; and a second photoluminescence material which generates light having a peak emission wavelength ranging from 640 nm to 690 nm, where the device is operable to generate white light with an IEC TM-30 Gamut Index Rg ranging from 105 to 115. The device can be operable to generate white light having an IEC TM-30 Fidelity Index Rf which ranges from 85 to 95 and a sum of Gamut Index Rg and fidelity index Rf is greater than or equal to 195 and less than or equal to 200.
