Light emitting device

A light emitting device, comprising

• a light emitting element having a dominant wavelength in a range of 430 nm or more and 500 nm or less, and
• a fluorescent material that is excited by light emitted from the light emitting element and has a light emission peak wavelength in a range of 507 nm or more and 660 nm or less, the light emitting device emitting light having a dominant wavelength in a range of 490 nm or more and 500 nm or less,
• the light emitting device having an S/P ratio, which is the ratio of a luminous flux in scotopic vision to a luminous flux in photopic vision, being 6.5 or less,
• the light emitting device having a light emission intensity in a light emission peak wavelength of the light emitting element that is greater than a light emission intensity in the light emission peak wavelength of the fluorescent material,
• wherein the light emitting device emits light having chromaticity coordinates (x, y) within an area in the xy chromaticity coordinate system of the CIE 1931 chromaticity diagram, wherein when the chromaticity coordinates (x=0.0082, y=0.5384) is defined as a first point, the chromaticity coordinates (x=0.0454, y=0.2950) is defined as a second point, the chromaticity coordinates (x=0.2000, y=0.3200) is defined as a third point, and the chromaticity coordinates (x=0.2000, y=0.4000) is defined as a fourth point, the area is demarcated by a first straight line connecting the first point and the second point, a second straight line connecting the second point and the third point, a third straight line connecting the third point and the fourth point, and a fourth straight line connecting the fourth point and the first point.
