Light emitting device

Abstract

Provided is a light emitting device that is bright in both scotopic vision and photopic vision, and has reduced glare for humans. The light emitting device includes 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, wherein the light emitting device emits light having a dominant wavelength in a range of 490 nm or more and 500 nm or less, wherein the light emitting device has an S/P ratio, which is the ratio of a luminous flux in photopic vision to a luminous flux in scotopic vision, being 6.5 or less, and wherein the light emitting device has a light emission intensity in the light emission peak wavelength of the light emitting element that is greater than that in the light emission peak wavelength of the fluorescent material.
