Abstract:
1. A light emitting device comprising a light emitting element, a red phosphor formed from a nitride phosphor and a green phosphor formed from a halosilicate, the emission spectrum having a first peak at a wavelength between 440 nm and 470 nm, a second peak at a wavelength between 510 nm and 550 nm and a third peak at a wavelength between 630 nm and 670 nm, the minimum relative light emission intensity between the second peak wavelength and the third peak wavelength of the emission spectrum being 52% or more and 80% or less of whichever the lower of the relative light emission intensity of the second peak wavelength and the relative light emission intensity of the third peak wavelength, wherein the red phosphor is activated with Eu and is represented by the following general formula (I): wherein M the green phosphor is represented by the following general formula (II) or general formula (III): formula (II) being formula (III) being
