LIGHT-EMITTING DEVICE Russian patent published in 2011 - IPC H01L33/50 

FIELD: physics.

SUBSTANCE: light-emitting device has a light-emitting element, a red luminophor formed from a nitride luminophor, and a green luminophor formed from a halogen-silicate, in whose radiation spectrum of which there is a first peak at wavelength between 440 nm and 470 nm, a second peak at wavelength between 510 nm and 550 nm and a third peak at wavelength between 630 nm and 670 nm. The minimum relative intensity of optical radiation between the second peak wavelength and the third peak wavelength is equal to or less than 80% of the least relative intensity of optical radiation at the second and third peak wavelengths.

EFFECT: light-emitting device has high quality of colour reproduction.
