Claim Text:
1. A light emitting device comprising: at least one light emitting element which has a peak wavelength in a range of 400 nm to 480 nm; and a sealing resin layer which covers the light emitting element, the sealing resin layer including a far-red phosphor which, when excited by excitation light from the light emitting element, emits light having a peak wavelength in a range of 700 nm to 800 nm, wherein the sealing resin layer further includes at least one type of red phosphor which, when excited by the excitation light from the light emitting element, emits light having a peak wavelength in a range of 600 nm to 700 nm, the far-red phosphor has a specific gravity in a range of 6.5 to 7.5, and the red phosphor has specific gravity in a range of 2.0 to 4.0.
